DESCRIPCIÓN DE LA ACCIÓN: EU-Diversify, INIA lenguado, MINECO Joan Cerdà.

1) Project Title: Exploring the biological and socio-economic potential of new/emerging candidate fish species for expansion of the European aquaculture industry (DIVERSIFY). 7FP-KBBE-2013-GA 602131, DIVERSIFY.

This 5-year-long project (2013-2018) has received funding from the European Union’s Seventh Framework Programme for research, technological development and demonstration (KBBE-2013-07 single stage, GA 603121, DIVERSIFY). The consortium includes 38 partners from 12 European countries –including 9 SMEs, 3 Large Enterprises, 5 professional associations and 1 Consumer NGO- and is coordinated by the Hellenic Center for Marine Research, Greece. Further information may be obtained from the project site at “www.diversifyfish.com”.

BRIEF DESCRIPTION – AIM:

The project DIVERSIFY has identified a number of new/emerging finfish species, with a great potential for the expansion of the EU aquaculture industry. Although the emphasis is on Mediterranean cage-culture, fish species suitable for cold-water, pond/extensive and fresh water aquaculture have been included as well. These new/emerging species are fast growing and/or large finfishes marketed at a large size and can be processed into a range of products to provide the consumer with both a greater diversity of fish species and new value-added products. The fish species to be studies include meagre (Argyrosomus regius) and greater amberjack (Seriola dumerili) for warm-water marine cage culture, wreckfish (Polyprion americanus) for warm- and cool-water marine cage culture, Atlantic halibut (Hippoglossus hippoglossus) for marine cold-water culture, grey mullet (Mugil cephalus) a euryhaline herbivore for pond/extensive culture, and pikeperch (Sander lucioperca) for freshwater intensive culture using recirculating systems.

These species were selected based both on their biological and economical potential, and to cover the entire European geographic area and to stimulate different aquaculture types. In collaboration with the SMEs and/or Large Enterprises, DIVERSIFY will build on recent/current national initiatives for species diversification in aquaculture, in order to overcome the documented bottlenecks in the production of these species and. Research will be carried out in the scientific disciplines of Reproduction and Genetics, Nutrition, Larval husbandry, Grow out husbandry, Fish health and Socioeconomics (including final product quality). The combination of biological, technological and socioeconomic research planned in DIVERSIFY are expected to

Seguimiento acciones estratégicas 2018

support the diversification of the aquaculture industry and help in expanding production, increasing aquaculture products and development of new markets. To ensure the dissemination and implementation of the new knowledge that will be developed by the project, a wide range of dissemination activities have been planned, targeted both to the aquaculture production and its associated sectors (i.e., food processing and retailing), as well as the European consumers.

Besides the technical improvement of the selected species, the socio-economic research in DIVERSIFY includes an applied market development approach solutions on perception of aquaculture products, market demand, buyer preferences, new product development, value adding and market development. These outcomes will help the EU aquaculture sector and the supply industry in targeted marketing and improvement of its international competitive position.

The project DIVERSIFY is funded under the 7th Framework Programme of the European Commission (7FP-KBBE-2013). This 5-year-long project is coordinated by Dr. Constantinos C Mylonas of the Institute of Marine Biology, Biotechnology and Aquaculture (IMBBC), one of the three institutes of the Hellenic Center for Marine Research (HCMR), and has a total budget of 11,8 million euro for its 5 year duration. Participating in the project are a total of 38 partners from Spain, France, Italy, Greece, Israel, Belgium, the Netherlands, Denmark, Norway, the United Kingdom, Germany and Hungary. The partners are mainly research and academic institutions, but the consortium includes also 3 Large Enterprises, 9 Small and Medium Enterprises (SME), 5 Professional Associations and one consumer NGO.

2) TÍTULO DEL PROYECTO: Gestión de los reproductores basada en su comportamiento para aumentar la producción de gametos y el éxito reproductivo en el lenguado senegalés (Solea senegalensis) cultivado (F1) y salvaje.

PROJECT TITLE: Broodstock management based on breeders behaviour to increase gamete production and spawning success of captivity reared (F1) and wild Senegalese sole (Solea senegalensis).

RESUMEN DE LA PROPUESTA:

El cultivo del lenguado senegalés (Solea senegalensis) sigue atrayendo la inversión de empresas privadas. Sin embargo, un aspecto que sigue siendo un cuello de botella al cultivo del lenguado senegalés es la disfunción reproductiva del comportamiento en los machos F1 que causa un fallo total de huevos viables de los stocks F1. La presente propuesta continúa con el proyecto RTA2011-50 donde se encontró que la presencia de peces salvajes que se reproducen, aumentan el comportamiento reproductivo y desove de los ejemplares F1. La propuesta pretende aprovechar estos avances para determinar el efecto a largo plazo de la presencia de reproductores salvajes con desove exitoso tiene sobre los ejemplares F1 incluidos en los grupos que han estado estabulados con los reproductores salvajes desde antes de la pubertad. Los objetivos novedosos de la presente propuesta son: a) Determinar el efecto de ejemplares salvajes que se reproducen con éxito sobre la producción de esperma de los ejemplares F1; b) Determinar el efecto de la retirada de parejas dominantes que se reproducen con éxito sobre la propia reproducción de la pareja dominante y sobre los ejemplares subordinados, c) Estudiar la producción de esperma en reproductores dominantes y subordinados d) Estudiar la relación entre el dominio espacial y la dominancia reproductiva con el fin de predecir la dominancia reproductiva a partir de la dominancia espacial y e) Comparar la roseta olfativa entre peces silvestres y cultivados y la respuesta del electro-olfatograma a feromonas potenciales. Estos objetivos se entregarán a través de manejo de reproductores y estudios de comportamiento reforzados con análisis histológicos, electro-

olfatograma y de expresión génica. Potencialmente estos avances proporcionaran a la industria mediante protocolos de gestión de reproductores que incrementaran el desove de los ejemplares F1, aumentaran la producción de esperma para la fecundación artificial y la producción de huevos de reproductores salvajes. Estos protocolos facilitarán la implantación de programas de mejora genética. La propuesta contribuye a la línea prioritaria de investigación 23.

General objective:

Seguimiento acciones estratégicas 2018

To determine the effect that the presence of successfully spawning breeders / social environment has on the reproductive capacity of other breeders and explore how to predict which breeders will be reproductively successful.

Specific Objectives

Objective 1: To determine the effect of the presence of spawning wild fish on reproductive success and sperm production of F1 fish.

Application: This objective aims to both increase F1 spawning and sperm production to quantities that can be used by the industry. It is anticipated that the long term exposure to wild fish spawning will increase the spawning from F1 fish to levels that the industry can use (predictable large quantities of fertilised eggs) and that increased sperm production will facilitate the collection of sperm for cryopreservation and/or direct use for artificial fertilisation. This is an innovative approach to the problem and will be the most comprehensive study to date on the effects of successful mating on the reproductive success of organisms that fail to reproduce.

Objective 2: To study sperm production in dominant and subordinate fish and determine the effect of removing dominant spawning pairs on the spawning of both the dominant pairs and subordinate fish.

Application: This objective aims to increase the spawning from a given number or biomass of wild breeders through innovative broodstock management procedures. At present a few breeders dominate the spawning in a wild broodstock. Successfully splitting a broodstock into many spawning pairs could increase egg production 5-10 times compared to a group in which 1-3 pairs dominate spawning and the majority of the breeders do not reproduce. The definition of which breeders produce more sperm will facilitate the collection of sperm for cryopreservation and/or direct use for artificial fertilisation.

It should be noted that objectives 1 and 2 have an apparent contradiction. Objective 1 has the hypothesis that spawning by wild fish increases spawning in F1 fish and objective 2 has the hypothesis that spawning dominant fish suppress spawning in non-spawning fish. Firstly it should be acknowledged that the two objectives address different situations, objective 1 addresses non-spawning F1 fish that have a reproductive dysfunction that blocks spawning and objective 2 non-spawning wild fish that do not have any reproductive dysfunction. However, it should be considered that F1 fish could also experience dominance from experienced wild breeders. In this context, in objective 1, the F1 breeders that have experienced wild spawning from before puberty that will not be held with wild fish will address this point. These F1 fish have been held since 2012 with wild spawning fish and a number entered puberty in 2014. The trial will start when all fish have passed puberty in 2016. In addition the successful broodstock management procedure that objective 2 aims to develop could be applied to the mixed F1 + wild breeder tanks in objective 1.

Task 2.1 Evaluation of the genetic variation in captive meagre broodstocks (led by FCPCT).

Preliminary studies have indicated that meagre broodstock in Europe, which were formed

from juveniles obtained from mainly a single commercial hatchery, have reduced genetic

Seguimiento acciones estratégicas 2018

variability as the juveniles originated from a small group of parents (Soula et al., 2011; Duncan

et al., 2013a). Fin clips will be taken from individuals in broodstock groups held for aquaculture

purposes (FCPCT, IRTA, HCMR, ARGO, FORKYS); a minimum of 30 fish will be sampled from

each of the 10 different broodstock groups from the participating RTD centres and SMEs. The

collection of finclips will be undertaken also in commercial hatcheries that are not participating

in DIVERSIFY and the following partners will coordinate the collection in different regions of

Europe: FCPCT, IRTA (Spain and Portugal), IFREMER (France), HCMR (Greece, Cyprus and

Turkey), UNIBA (Italy and Malta) and IOLR (Israel). Already defined genetic markers (Andree et

al., 2010; Soula et al., 2011) will be applied and existing multiplex optimised and basic

population genetics parameters (allelic richness, heterozygosity indices and inbreeding

coefficients) will be estimated in order to describe the genetic status of captive broodstock

and identify future needs. These needs will probably be that the genetic pool must be enlarged

with the incorporation of wild stock or the mixing of existing captive stocks to ensure that the

genetic variability of the base populations used in European aquaculture will enable the

genetic selection of desirable production traits whilst avoiding problems associated with

inbreeding. This task will result in deliverable D2.2 Genetic characterisation of different

meagre captive broodstocks and evaluation of available variability.

Task 2.2 Development of protocols for paired crossing in spontaneous spawning (led by IRTA).

Previous studies (IRTA) examining parentage contribution, indicated that 86% of spawns in

communal spawning tanks were from only two parents, indicating that planned single paired

crosses could be achieved by isolated pairs. A total of six pairs will be selected that are at the

right post vitellogenic stage or have flowing milt (Duncan et al., 2012) and placed in spawning

tanks (IRTA). At weekly intervals (total of 6 weeks), the pairs will be induced to spawn with an

injection of 15 μg GnRHa kg-1. From the second week onwards when fish are manipulated to

inject the females, the males will be transferred to a different tank in order to be crossed with

a different female, producing a total of 36 families at the end of the experiment. Egg fecundity

and quality (i.e., morphology, fertilisation, hatching and larval survival) will be assessed using

96-well microtiter plates (Panini et al., 2001; Duncan et al., 2012). Micrtotiter plates are loaded

individually with fertilized eggs and are maintained in a controlled temperature incubator until

yolk-sack absorption. The plates are examined under a stereoscope every day, and embryonic

development, hatching and larval survival are monitored. This task will result in deliverable

D2.3 Protocol for paired spontaneous tank spawning of meagre.

Task 2.3 Description of sperm characteristics and cryopreservation methods (led by IFREMER).

Part of the state-of-the-art of in vitro fertilization protocols is to have good quality sperm

available when the females ovulate and ova are stripped. At three time-points in the spawning

season, sperm quality of 10 males held in IRTA will be assessed (IFREMER, IRTA) by (a) sperm

concentration through image analysis, (b) sperm motility (% mobile cell, velocity, linearity of

tracks) using the CASA plugin of ImageJ software (Wilson-Leedy & Ingermann, 2007; Fauvel et

al., 2010), (c) sperm membrane integrity by eosin/nigrosin sperm viability test (Björndahl et al.,

2003) and (d) sperm energetic status using ATP measurement kits (Boryshpolets et al., 2009).

Then chilled storage will be studied according to Fauvel et al., (2012) and cryopreservation will

be adapted using a commercial diluent (Cryofish from Cryobiosystem, France). The conditions

of sperm dilution in terms of volume, osmolality, pH and cryoprotectant type will be tested by

Page 10: FICHA PARA EL SEGUIMIENTO DE ACCIONES ESTRATÉGICAS …€¦ · 2) Universidad de Cádiz (UCA) y la Universidad de Alicante (UA) 3) Dirección General de Pesca y Acuicultura ... que

Seguimiento acciones estratégicas 2018

comparison of sperm motility performance based on CASA analysis. This task will result in

deliverable D2.6 Description of sperm characteristics and cryopreservation protocol of meagre

sperm.

Task 2.4 Development of in vitro fertilization methods for planned crosses (led by IRTA). The

state-of-the-art method to obtain planned crosses to produce desired families is strip

spawning of eggs and in vitro fertilisation. Ten females (five wild and five cultured fish) at the

right post vitellogenic stage (Duncan et al., 2012) will be induced to ovulate at weekly intervals

with a single injection of 15 μg GnRHa kg-1 (IRTA). The females will be examined for ovulation

at predetermined hours post injection, based on preliminary data from HCMR indicating that

ovulation occurs after 32-36 h at 19°C. This work will be lead by IRTA with participation from

HCMR and IFREMER, who will send their scientists to the IRTA facilities at the time of the

experiment. When obtained, ovulated eggs will be fertilised with fresh or stored sperm and

egg quality parameters determined as above (Task 2.2). A data set will be built up that will

determine the interaction between, female stage at stimulation, time of response to hormone

injection (ovulation) and egg quality to identify optimal stripping times after hormone

injection. This task will result in deliverable D2.7 Protocol for the strip spawning of meagre

females and in vitro fertilization.

Task 2.5 Development of Single Nucleotide Polymorphisms (SNP) marker tools for the genetic

characterization of fast and slow growers (led by HCMR). One of the principal bottlenecks to

meagre production is variable growth rates, causing uncertainty in the prediction of total yield

from each ongrowing cycle. Fast and predictable growth is an important and highly desired

trait, which affects the profitability of food animal production, since feed costs account for the

largest proportion of production costs. SNPs explain the greatest part of the genetic

differences between individuals and are suitable for genetic evaluation and strategies that

employ molecular genetics for selective breeding. Therefore, this task aims at using SNPs to

identify markers and genes associated with genetic variation in growth through Next

Generation Sequencing (NGS) of the whole transcriptome of 10 fish from different families and

phenotypic size (of the same age) that will provide a data-set of over 100,000 SNPs. The

chosen SNP discovery strategy will be two-fold. First, the whole transcriptome of muscle and

liver of more than 10 fish from different families and phenotypic size will be sequenced to gain

information regarding the gene sequence of meagre and to identify thousands of SNPs that

can have impact on the functional role of protein-coding genes. This step will lead to a

catalogue of polymorphic loci at the expressed part of the genome and will set the ground for

understanding growth and other traits of interest in meagre. Second, to identify SNPs that will

have significant association with growth, we will conduct a preliminary QTL mapping

experiment using ddRAD (double-digest Restriction site Associated DNA) Sequencing. Fin clip

samples and phenotypic growth data (weight and morphometric measures) will be obtained

from more than 250 individual meagre from tasks in WP20 Grow out husbandry – meagre.

These fish are going to be genotyped in order to infer parentage allocations and the progeny

from one or two large families (approx. 130 fish), which exhibit the greatest phenotypic

used in a genetic linkage mapping analysis to build the first linkage map of the species. Finally,

a second RADseq library will be constructed following the same protocol for some 140

breeders from SMEs and based on the results obtained from the QTL analysis a primary

selection programme will be initiated based on a sub-group of fish. This task will result in

deliverables D2.1 SNP library and chip to genetically characterize meagre or to use in marker

assisted breeding programs, D2.4 Construction of a genetic linkage map in meagre (Mo36), and

D2.5. Identification of genetic markers related to growth for use in marker assisted breeding

programs for meagre through QTL mapping (Mo 36).

Task 6.3 Development of spawning induction procedures (led by IEO). Available information

from Partners of DIVERSIFY (Mylonas et al., 2004; Fauvel et al., 2008; Peleteiro et al., 2010)

indicates that GnRHa implants (HCMR) may be effective in inducing oocyte maturation and

ovulation, and that stripping protocols may be needed. Therefore, GnRHa implants will be

used in the available stocks (HCMR, CMRM, and MC2). All broodstocks will be monitored for

reproductive function (see task 6.2). When fish are at the correct maturation stage they will be

induced to spawn using GnRHa implants, testing doses of 50-200 μg kg-1. Two approaches will

be taken: (a) Fish will be placed in large tanks ≥40-m3 under controlled photothermal

conditions and allowed to spawn spontaneously (HCMR, MC2). Large tanks were shown in

groupers to overcome the lack of spawning after ovulation (Marino et al., 2003). If fish fail to

spawn, they will be sampled to identify failure of maturation or spawning, the latter being the

experience in smaller tanks. Depending on the outcome, the approach will be adjusted with

new doses (insufficient maturation) or strip spawning (lack of spawning). (b) Experiments will

be conducted in smaller tanks (≤15 m3) and fish will be monitored for ovulation. Ovulated eggs

will be inseminated in vitro using sperm from spermiating males and the eggs will be incubated

(IEO, CMRM, HCMR). If fish fail to spawn, they will be sampled to confirm if the failure is

related to lack of maturation and new implant doses will be tested. A researcher from IRTA will

visit to participate in spawning induction procedures. Eggs will be monitored for quality (See

Task 2.2). Nutritional quality (See WP3) of egg batches will also be determined (CMRM, ULL) to

compare with nutritional status of wild fish (Task 6.2) and to identify nutrients that may be

lacking from the broodstock diet. Samples will be sent to ULL for nutritional analysis. Between

the different stocks, husbandry variables such as sampling procedures, disturbance due to

sampling, photothermal regime and nutrition (raw fish supplemented with commercial

broodsotck diets) will be standardized and maintained as close to identical as possible.

Standardization of these parameters will facilitate comparison of results from different stocks

to determine optimal tank sizes, implant doses and spawning protocols. This task will

contribute to deliverables D6.7 Develop a spawning induction method for spontaneous

spawning of wreckfish in large tanks, and will also result in D6.3 Develop spawning induction

methods with in vitro fertilization of wreckfish and D6.6 Define an in vitro fertilization protocol

to be employed by the industry to spawn wreckfish.

Task 7.3 Optimization and scale-up of a breeding protocol for grey mullet in captivity (led by

IOLR). The best performing hormonal therapy for accelerating gonadal development (based on

results of Task 7.1) and spawning induction (based on Task 7.2) will be employed to test our

ability to further extend the reproductive season (i.e., multiple spawns per individual,

manipulated photo-thermal regimes), as well as improve reproductive productivity by mass-

spawning (IOLR, DOR). For that purpose captive-reared sexually mature broodstocks will be

acclimated to either ambient or shifted photo-thermal conditions. Spawning induction trials

will be carried out using broodstocks differing in their size (2 to 20 individuals) and sex ratio

(i.e., equal, skewed in favour of males, skewed in favour of females). Spawned females will be

subjected again to the same hormonal treatment (as above), in order to obtain further spawns

(IOLR). At the same time, the selected hormonal therapy will be applied to induce spawning in

wild-caught mature fish vs. wild fish that will be acclimated to and matured in captivity (IRTA).

This step is expected to confirm the consistency and reliability of the spawning induction

protocol. Furthermore, the biochemical composition of wild fish and the spawned eggs from

both groups will be analysed (ULL) (same procedure as Task 3.1) to provide an important

reference for identifying specific nutritional requirements for improved egg quality that will be

correlated with larval quality (hatching, larval survival to yolk absorption). This task will

contribute to deliverables D7.3 Comparative effectiveness of hormonal treatments for

spawning induction in captive grey mullet and D7.7 Development of a breeding protocol for

captive reared grey mullet broodstock based on optimized hormonal treatment, group

structure and photo-thermal regime.

2) Broodstock management based on breeders behaviour to increase gamete production

and spawning success of captivity reared (F1) and wild Senegalese sole (Solea

senegalensis).

Objective 1: To determine the effect of the presence of spawning wild fish on reproductive success and sperm production of F1 fish. Participants: IRTA and IEO.

Trail 1: The following tanks of broodstock will be set up in both IRTA and IEO Santander: a) Six mixed tanks of 10 male and 10 female F1 broodstock and 5 wild males and 5 wild females (three in IRTA and three in IEO). IRTA has two tanks already set up which will be maintained from project RTA2011-50 and will need to set up one new tank. IEO has three tanks set up, but one tank did not produce fertilised spawns in 2013 and 2014 and may need to be re-established with new wild broodstock. b) Two control tanks with 10 male and 10 female F1 broodstock, (one in IRTA and one in Santander). These tanks are available and already set up in each centre.

The tanks will be managed as follows: a) Four mixed tanks will be left undisturbed (two in IRTA and two in IEO). b) Two mixed tanks (one in IRTA and one in IEO) and two control tanks (one in IRTA and one in IEO) will be sampled for F1 sperm quality at three time points each spring spawning season (early in the season in the middle of the season and towards the end of the season) in two consecutive years. These manipulations for sperm extraction have been repeatedly make in other projects and do not affect spontaneous spawning. However, four tanks will not be disturbed to give maximum opportunity to newly spawning F1 breeders. Egg quality will be recorded and paternity analysis make of all viable spawns. Sperm quality parameters will be compared with an ANOVA between males with and without wild spawning fish.

Trial 2: The following tanks of broodstock will be set up in IRTA: a) Two tanks of 10 male and 10 female F1 broodstock that have been reared from before puberty in tanks with spawning wild broodstock. b) One tank of 10 male and 10 female F1 broodstock that have been reared from before puberty in tanks with F1 broodstock that liberate unfertilised eggs. c) One tank of 10 male and 10 female F1 broodstock that have been reared in isolation as a single year class. All these tanks will be left undisturbed. Egg quality will be recorded and paternity analysis make of all viable spawns.

Objective 3: To develop group dominance tests. Participants: IRTA

In project RTA2011-50 dominance tests (Overli et al., 2004) were successfully applied to pairs of Senegalese sole to identify dominant and subordinate fish in relation to the resources food and space (small area with substrate). The dominate fish spent more time resting on or swimming above the subordinate fish (spatial dominance). Groups of 6 individuals will be pair tested (feeding and resting on another fish), each fish against each fish a total of 15 pair tests to give a ranking of dominance. The same six fish will then be group tested (feeding and resting on another fish) and fish ranked in dominance in relation to latency to feed, dominant behaviours between individuals, number of incidents and time a fish rests on another fish. These group tests will use focal observation of distinctive behaviours using an ethogram (Carazo 2012) in a similar way to other group dominance behavioural research on round fish (Huntingford et al 1993; Carvalho et al 2013); however, agonistic round fish behaviours cannot be applied to a relatively passive flatfish. The ranks from paired and group tests will be contrasted to validate group tests. A video / photo identification technique, developed in project RTA2001-50) (modified from Sánchez et al 2012 and Huntingford et al 2013) will be used to identify individual fish.

Expression of genes related to dominance will be explored as possible biomarkers. The expression of the 30 mRNA transcripts that were tested for relevance to individual coping styles in project RTA2011-50 will be examined in relation to dominance. Dominate and subordinate individuals will be identified in dominance tests, tissues obtained and total RNA extracted (TriReagent Protocol). Expression levels of specific primer sets will be quantified by real-time PCR (Biorad; Pfaffl 2001; MacKenzie et al 2010).

Objective 4: To explore the relation between spatial and reproductive dominance with the aim to predict reproductive dominance from spatial dominance. Participants: IRTA and IEO

High quality video recordings will be made of the behaviours in the broodstock tanks during the peak half hour of activity (Carazo 2012). Focal observations will be made to describe dominate behaviours such as fish resting on another fish that will be identified in objective 3. The behaviours between individuals and the number of dominant / subordinate behaviours will be used to make a classification of dominant and subordinate fish that will be compared with reproductive dominance determined from microsatellite paternity analysis. Principal components analysis (PCA) or correlation analysis and chi-squared analysis will be applied to determine relationships between the two types of dominance and if distributions of dominant and subordinate fish differ.

Objective 5: To compare between wild and cultured fish the olfactory rose and electro-olfactogram response to potential pheromones. Participants IRTA

Morphological comparison: This study has been started. Wild and F1 Senegalese sole (n=10 of each group) were sacrificed and histology of olfactory rosettes prepared with the stains to show general morphology, cell structure, mucus cells and histochemical structure. The cuts will be analysed and a manuscript prepared as part of this proposal.

Transcriptome comparison: Total RNA has been extracted (TriReagent Protocol) from the upper and lower olfactory rosettes of 4 wild and 4 F1 individuals (total 16 olfactory rosettes). The individuals were held in the same conditions and all had motile sperm when sacrificed in the middle of the reproductive season (May 2014). Six of the 16 RNA samples have been sent for RNA-seq (CNAG, Barcelona http://www.cnag.cat/) as a preliminary start to this work. The complete sample set would be processed in the present proposal. The transcriptome data will be processed and analysed to determine differential gene expression (Manchado et al 2008; Forne et al 2011; Infante et al 2011; Cerda Manchado 2013; Matin-Juez et al 2013; Hachero-Cruzado et al., 2014 - these groups support the present proposal, see supporting letters).

Briefly, Illumina short-reads will be pre-processed using SeqTrimNext pipeline and filtered-reads will be mapped onto the reference transcriptome of S. senegalensis v4.1 (http://www.juntadeandalucia.es/agriculturaypesca/ifapa/soleadb_ifapa/) using Bowtie2. Total number of transcript counts will be extracted using Sam2count.py (https://github.com/vsbuffalo/sam2counts). Finally, differential gene expression analysis will be carried out using edgeR with a p-value cut-off of 0.05 and using the Benjamini-Hochberg method for multiple testing correction as implemented in the Robina software (Lohse et al., 2012).

Electro-olfactogram: This work will be completed in an “INIA estancia” which will be undertaken by the PhD student Elvira Fatsini, a member of the research group in the proposal. The visit will be to the laboratory of Dr. Peter Hubbard, who is a world leader in olfactory physiology (see letters of support). The electro-olfactogram is a standard technique used in this laboratory with Senegalese sole (Velez et al., 2005; 2007a;b; 2009). The aim of the visit will be to explore which chemicals act as reproductive pheromones. The transcriptome work will identify olfactory receptor types; this may indicate classes of chemicals that act as pheromones. HPLC will be used to fractionate the eluate of breeders’ urine (obtained by solid-phase extraction); this contains high olfactory activity (Carazo 2012, work completed in a visit with Dr. Hubbard). The possible pheromones and fractionated urine will be compared for responses in an electro-olfactogram using wild and F1 fish to indicate which chemicals may have pheromonal activity in the urine, and to explore possible differences in sensitivity between wild and F1 fish.

Continuation of Tasks 2.4, 2.5, 6.3 and 7.3

Task 2.4 Development of in vitro fertilization methods for planned crosses (led by IRTA). The state-of-the-art method to obtain planned crosses to produce desired families is strip spawning of eggs and in vitro fertilisation. Ten females (five wild and five cultured fish) at the right post vitellogenic stage (Duncan et al., 2012) will be induced to ovulate at weekly intervals with a single injection of 15 μg GnRHa kg-1 (IRTA). The females will be examined for ovulation at predetermined hours post injection, based on preliminary data from HCMR indicating that ovulation occurs after 32-36 h at 19°C. This work will be lead by IRTA with participation from HCMR and IFREMER, who will send their scientists to the IRTA facilities at the time of the experiment. When obtained, ovulated eggs will be fertilised with fresh or stored sperm and egg quality parameters determined as above (Task 2.2). A data set will be built up that will determine the interaction between, female stage at stimulation, time of response to hormone injection (ovulation) and egg quality to identify optimal stripping times after hormone injection. This task will result in deliverable D2.7 Protocol for the strip spawning of meagre females and in vitro fertilization.

Task 2.5 Development of Single Nucleotide Polymorphisms (SNP) marker tools for the genetic

characterization of fast and slow growers (led by HCMR). One of the principal bottlenecks to

meagre production is variable growth rates, causing uncertainty in the prediction of total yield

from each ongrowing cycle. Fast and predictable growth is an important and highly desired

trait, which affects the profitability of food animal production, since feed costs account for the

largest proportion of production costs. SNPs explain the greatest part of the genetic

differences between individuals and are suitable for genetic evaluation and strategies that

Seguimiento acciones estratégicas 2018

employ molecular genetics for selective breeding. Therefore, this task aims at using SNPs to

identify markers and genes associated with genetic variation in growth through Next

Generation Sequencing (NGS) of the whole transcriptome of 10 fish from different families and

phenotypic size (of the same age) that will provide a data-set of over 100,000 SNPs. The

chosen SNP discovery strategy will be two-fold. First, the whole transcriptome of muscle and

liver of more than 10 fish from different families and phenotypic size will be sequenced to gain

information regarding the gene sequence of meagre and to identify thousands of SNPs that

can have impact on the functional role of protein-coding genes. This step will lead to a

catalogue of polymorphic loci at the expressed part of the genome and will set the ground for

understanding growth and other traits of interest in meagre. Second, to identify SNPs that will

have significant association with growth, we will conduct a preliminary QTL mapping

experiment using ddRAD (double-digest Restriction site Associated DNA) Sequencing. Fin clip

samples and phenotypic growth data (weight and morphometric measures) will be obtained

from more than 250 individual meagre from tasks in WP20 Grow out husbandry – meagre.

These fish are going to be genotyped in order to infer parentage allocations and the progeny

from one or two large families (approx. 130 fish), which exhibit the greatest phenotypic

variation will be used for RADSeq library construction and sequencing on an Illumina HiSeq

platform. Following sequencing, SNP discovery pipelines will be run to identify common SNPs

among all progeny that will provide the basis for QTL mapping. Discovered SNPs will also be

used in a genetic linkage mapping analysis to build the first linkage map of the species. Finally,

a second RADseq library will be constructed following the same protocol for some 140

breeders from SMEs and based on the results obtained from the QTL analysis a primary

selection programme will be initiated based on a sub-group of fish. This task will result in

deliverables D2.1 SNP library and chip to genetically characterize meagre or to use in marker

assisted breeding programs, D2.4 Construction of a genetic linkage map in meagre (Mo36), and

D2.5. Identification of genetic markers related to growth for use in marker assisted breeding

related to lack of maturation and new implant doses will be tested. A researcher from IRTA will
