Commercial Scallop Dive Fishery (Port Phillip Bay)

Background This Commercial Fishery Plan (Plan) relates to the Commercial Scallop Dive Fishery (Port Phillip Bay) (the Fishery), which is a new fishery created at the end of 2013 by way of a public auction. This Plan is a guide as to how the licence holder (Port Phillip Bay Scallops) wishes to develop the fishery over the coming5 years(2016 to 2021), including providing input to the ongoing management of the Fishery. This Plan is provided to assist the Department of Economic Development, Jobs, Transport and Resources (DEDJTR) in the process for developing a Scallop Dive Fishery (Port Phillip Bay) Management Plan in accordance with the Fisheries Act 1995.

Objectives of the Fishery The objectives of the Fishery are to:

a) Establish and develop the Fishery, and doing so in an ecologically and economically sustainable manner.

b) Protect and conserve the existing habitats, resources of the Fishery and the ecosystem.

c) Promotion of world’s best practice, sustainable commercial fishing practices.

d) Engage in research to understand the Fishery for both the development and sustainability of the Fishery.

e) Promote the Fishery and the best practice fishing techniques.

f) Coexist within the Fishery with other commercial fishing industries, the recreational fishing industry and the community.

Development of Fishery Port Phillip Bay Scallops proposes the ongoing development of the Fishery by establishing a 5 year Fishery Management Plan in accordance with Part 3 of the Fisheries Act 1995 encompassing the following:

1. Staged Development The Total Allowable Commercial Catch (TACC), 146 tonnes, gazetted for this fishing season (1st April 2015 to 31st March 2016) equates to approximately 4% of the total available biomass identified in the Department’s survey conducted in 2014. Port Phillip Bay Scallops proposes that TACC over the next 5 years is calculated in accordance with the following percentages of the total available biomass, and as assessed for each individual spatial zone: a) Year 1 (1st April 2016 to 31st March 2017): 10%

b) Year 2 (1st April 2017 to 31st March 2018): 10 - 15%

c) Year 3 (1st April 2018 to 31st March 2019): 10 - 20%

d) Year 4 (1st April 2019 to 31st March 2020): 10 - 20%

e) Year 5 (1st April 2020 to 31st March 2021): 10 - 20% Port Phillip Bay is divided between 6 spatial zones as follows:

This staged development will allow: i. The collection of additional data to support the sustainability of the fishery

ii. Development of export markets

iii. Development of further areas to undergo water classification Within the next five year period (2016 to 2021), it is not proposed that harvesting will be conducted in Zones 2 and 6 due to unsuitable diving conditions and complexities in water classification.

2. Biomass Surveys

Over the next 2 years Port Phillip Bay Scallops proposes that fishery independent surveys be conducted across zones which the company wishes to continue harvesting. It is proposed that these surveys be managed by DEDJTR and that funding contribution is not only from Port Phillip Bay Scallops, as the Licence Holder, but also from the recreational sector. It is proposed that surveying work will be conducted between the months of July to October. The surveys, together with other collected data, will be used to calculate the available biomass in each surveyed zone, which will then form the basis on which the TACC will be calculated on. Port Phillip Bay Scallops will submit to DEDJTR the survey findings, together with a scientific report which compiles and analyses the survey results, as part of its application to increase the TACC. It is proposed that DEDJTR will have an opportunity to review these results and engage internal or external experts to provide advice, as may be required. Port Phillip Bay Scallops also proposes that it has the ability to carry out further surveys, at its sole discretion, which results will be used in conjunction with catch effort data obtained throughout the fishing year. Annexed is a copy of the biomass survey specifications which have been developed in accordance with the Baseline Management Arrangements and in consultation with DEDJTR.

3. Factors to Consider when Calculating TACC There are many factors that may impact on Port Phillip Bay’s ability to catch the TACC, or the catch per unit effort (CPUE) during the season. These include:

• Unfavorable weather conditions

• Spatial distribution patterns and concentration • Equipment availability and possible breakdown • Market forces and demand for scallops during particular months of the year • Demand for export and successful application for export • Water classification matters including possible closure of areas due to significant rainfall

events or environmental hazards

Page 4: Commercial Scallop Dive Fishery (Port Phillip Bay) · This Commercial Fishery Plan (Plan) relates to the Commercial Scallop Dive Fishery (Port Phillip Bay) (the Fishery), which is

• Diver safety during particular times and under particular conditions • View to protect and develop certain stocks for future development • Poorer condition of scallops during mid December through to end of March

Therefore, it is proposed that there is no penalty applied to any future TACC (should the full quota not be harvested) provided any catch and effort data are supported by a biomass survey showing that the fishery is not deteriorating. We strongly expect that diver collected information will be included when discussing the above matters in TACC considerations.

4. Application of Scientific Data

That each zone is treated as an independent zone in all aspects including in relation to catch and effort data, biomass survey results and setting the TACC. For example, in the event that the TACC is not caught in its entirety in a particular zone, or if catch and effort data is not strong in a particular zone, that should not be extrapolated across all zones. That the available biomass is to be calculated on the mean. The TACC is then to be calculated on the available biomass and in accordance with the percentages identified above. When interpreting any catch and effort data the following factors also need to be considered: a) Weather conditions on any particular dive. An unfavorable weather event may not be

significant enough to prevent diving, however, it may impact on harvesting abilities.

b) Diving conditions on any particular dive. Certain factors may impact on the diver’s harvesting abilities such as:

a. Current

b. Clarity of water

c. Wind

d. Underwater terrain

e. Depth

f. Bottom conditions such as silt, sand and weeds It is proposed that Port Phillip Bay Scallops will develop a comprehensive diver log to capture this additional and other non-mandatory data.

5. Timeframe for TACC That the following timeframe be observed each year when declaring a TACC for the fishery: 1. Presentation by Port Phillip Bay Scallops to DEDJTR of all relevant scientific data and findings

together with an application for science supported TACC.

2. First week in November - declaration of proposed TACC in each of the spatial zones by way of a draft quota notice.

Page 5: Commercial Scallop Dive Fishery (Port Phillip Bay) · This Commercial Fishery Plan (Plan) relates to the Commercial Scallop Dive Fishery (Port Phillip Bay) (the Fishery), which is

5 | P a g e

3. Last week in November to first week of December - public workshop to be convened by the

Department in conjunction with Port Phillip Bay Scallops and stakeholders in accordance with the requirements of the Fisheries Act 1995.

4. Up to third week in December - public submissions to be received.

5. Second week in January - TACC to be gazetted.

6. Recreational Sector In 2015 it became apparent that there is a lack of sound knowledge and evidentiary data on the annual take of scallops in Port Phillip Bay by recreational divers. This information gap needs to be addressed through the implementation of additional measures, such as information being collected when issuing annual recreational licences, or a nominal fee in addition to the recreational licence for recreational divers who indicates that they intend to dive for scallops. This collected revenue could then assist with the provision of science for the fishery. It is proposed by Port Phillip Bay Scallops that there is no need to set, discuss or consider a recreational quota for scallops as there is no way of managing, controlling or understanding the actual take. Further, the recreational sector are adequately provided for as a result of the following: a) Two exclusion zones are in place which are unable to be commercially harvested

b) The supplementary biomass survey conducted by DEDJTR in 2015 in the exclusion zones

identified that there is a significant biomass in the exclusion zones. These findings are significant and adequately mitigates any potential risk presented by anticipated catch levels of scallops by recreational divers.

Management of the Fishery The Fishery will be managed to have regard to the objectives outlined above,whichwill ensure that the Fishery is ecologically and economically sustainable, having regard to commercial, recreational, traditional and non-consumptive uses. In particular Port Phillip Bay Scallops intends to meet its objectives by the following management:

a) Establish and develop the Fishery, and doing so in an ecologically and economically sustainable manner:

Conducting research of the Fishery in accordance with step 1 as discussed above. Plan the business development on the basis of the outcomes of scientific research.

b) Protect and conserve the existing habitats, resources of the Fishery and the ecosystems.

Hand diving for the scallops ensures that there is nil to minimal impact on existing habitats of the Fishery. All divers will be highly qualified and will be trained. The TACC in each of the zones will ensure that the existing population of scallops is sustainable.

Page 6: Commercial Scallop Dive Fishery (Port Phillip Bay) · This Commercial Fishery Plan (Plan) relates to the Commercial Scallop Dive Fishery (Port Phillip Bay) (the Fishery), which is

6 | P a g e

c) Promotion of world’s best practice, sustainable commercial fishing practices.

As detailed in b) above the Fishery will be sustainable having regard to hand diving and the TACC. Port Phillip Bay Scallops intends to engage in ongoing awareness and promotion of the sustainability of the Fishery through media outlets and the sale of the scallops.

d) Engage in research to understand the Fishery for both the development and sustainability

of the Fishery. As detailed above, research will be ongoing, both mandatory and voluntary, in relation to the Fishery.

e) Promote the Fishery and the best practice fishing techniques.

As detailed above, Port Phillip Bay Scallops will be involved in ongoing promotion of the Fishery including the uniqueness and importance of hand diving within the Fishery. This promotion will include through media outlets, the involvement of industry spokespersons and well known and reputable identities within the fishing and food industry.

f) Coexist within the Fishery with other commercial fishing industries, the recreational

fishing industry and the community. The Fishery contains other stakeholders such as: a) Recreational fishing

b) Commercial fishing for other species, using other methods c) Shipping and transport d) Personal use of Port Phillip Bay Port Phillip Bay Scallops will coexist in the Fishery with these other stakeholders. This will be achieved by: i. Holding necessary meetings with representatives of other stakeholder groups, including

the recreational fishing sector, if required.

ii. Being excluded from two zones within the Fishery as identified in Figure 4 of the Management Arrangements.

iii. Ensuring access to the Fishery by the recreational fishing industry without interruption

by Port Phillip Bay Scallops. iv. Ensuring the high qualification of divers including the importance of coexistence and

safety of all stakeholders in the Fishery.

Co Management Arrangements Port Phillip Bay Scallops will maintain a close relationship with the DEDJTR including, but not limited to:

1. Real time reporting Real time reporting in relation to ensuring compliance with the TACC and zone restriction is mandatory:

• Prior to launching

• Prior to landing; and • Post landing

This reporting will be achieved by the use of an electronic application downloaded on a mobile phone device (the electronic application) and the use of a vessel monitoring system.

2. Daily Catch Records Daily catch information will be supplied to the DEDJTR and will be supplied for each trip. The collection of this data is through the electronic application, together with voluntary measures such as diving conditions captured in a comprehensive diver log (to be developed).

3. Catch Disposal Records The catch disposal record (CDR) will account for all scallops landed under the licence. The CDR is required to accompany the scallops from the landing site to the point of sale or consignment. Where the scallop catch is split between two or more purchasers at the point of landing, a separate CDR will be required for each purchaser. The sale of scallops beyond the point of landing will need to be accompanied with a sales receipt. The CDR will be recorded in a book to be supplied by the DEDJTR.

4. Annual Report An annual performance report will be submitted by Port Phillip Bay Scallops to the DEDJTR outlining the performance of the fishery for the previous 12 months and by no later than 31 May of each year and in accordance with the Fisheries Act 1995. The report is to be published on the DEDJTR’s website. The report will include the following:

• Catch information (by zone and month)

• Effort information (by zone and month)

• Information on data collection, analyses and assessments completed.

5. Reporting on additional information collected by divers Any additional information collected by divers within the Fishery during dives, such as the presence of noxious weeds and other species will be reported to the DEDJTR.

6. Sharing information collected from research conducted in the Fishery Data and research results collected by Port Phillip Bay Scallops within the Fishery will be presented and shared with the DEDJTR as decided from time to time by Port Phillip Bay Scallops to assist with understanding, the sustainability and development of the Fishery.

The relationship between Port Phillip Bay Scallops and the DEDJTR will be one of transparency and information sharing with the view that the Fishery may be further understood, maintained and developed.

Future changes required to assist with the ongoing development of the Fishery Port Phillip Bay Scallops wish to flag the following legislative and regulative requirements that it would like to have reviewed over the next 24 months:

1. Margin of error allowed in the weight to be recorded to the Department, which is currently 0.1 kg.

2. Extension of timeframe to 60 minutes for the weighing of scallops once landed, from the current time limit of 20 minutes.

3. Ability to transfer catches between vessels to enable separate vessels to transport the scallops to shore.

4. Portarlington to be permanently listed as an authorised landing site.

5. Ability to fish across multiple zones within the one trip, provided tractability can be established.

6. Ability to traverse through exclusion zones,noting the availability of the vessel monitoring system data to verify that Port Phillip Bay Scallops is not harvesting within these exclusion zones.

ANNEXURE

Tender for the provision of a fishery independent survey for Port Phillip Bay Scallops Pty Ltd

Background:

Port Phillip Bay Scallops operates as the sole licensed for the harvesting of scallops within the Port Phillip Bay.

As part of the license requirements and in order to satisfy the Department of Fisheries annual quota setting process the company is required to conduct an annual scallop abundance survey utilising methods prescribed within this document.

The fishery independent survey involves the engagement of either fisheries Victoria or an independent operator or the company itself to conduct the survey with Fishery staff in attendance to observe the process.

This survey will be the second abundance survey conducted since the scallop industry was closed in 1998. Last year the company engaged the services of Fisheries Victoria to conduct the first survey since closure.

This year the company has determined that they will engage an outside contractor to conduct the survey.

The method of data collection is viadiving and hand collection of scallop samples from 73 random sites spread over the bay in the zones designated for harvesting operations. At each site 2 x 50m, parallel transects 1 metre wide are swum by divers where all scallops are collected.

The 73 transect sites will be allocated in zones 1,3,4,&5.

Zones 2 and 6 have been deemed unsuitable for harvesting and (as was the case with last year’s survey) will not be designated with sampling sites.

Data collection via Survey

A fishery-independent survey is designed to provide data on:

• Density (number of scallops per m2); and • Size structure of sampled scallops.

These data would be combined with additional (non-mandatory) data such as length-to-weight relationships, size/age structure and fine-scale spatial information, to covert the survey data into information that can be used to empirically set TACC/s (Total Allowable Commercial Catch) at the fishery and zone level based on current information (providing scope for a larger change to the TACC). More information on the additional data required to support the fishery is provided in ‘Additional (non-mandatory) data’ below.

Page 11: Commercial Scallop Dive Fishery (Port Phillip Bay) · This Commercial Fishery Plan (Plan) relates to the Commercial Scallop Dive Fishery (Port Phillip Bay) (the Fishery), which is

11 | P a g e

It is important to note that, due to the variable nature of scallop fisheries, the fishery-independent survey must be conducted on an annual basis to inform the TACC. If a survey is not conducted prior to the season, the TACC reverts to initial values.

Fishery-independent survey design

The design of the fishery-independent survey (FIS) is based on the survey design used to estimate scallop abundance for the commercial scallop dredge fishery from 1982 to 1996. This survey design represents a starting point that can be refined by the licence holder over time (see below).

The survey uses a random stratified sampling design of six strata (Appendix , Figure 1). The boundaries of the strata are based on bathymetry (the boundary of Stratum 2 is the 20m deep contour) and historical scallop abundances in Port Phillip Bay (Coleman 1998).

The number of sampling sites in each stratum is based on historical abundance.

The number of sample sites will be distributed as follows:

Zone 1 -15

Zone 2 – 0

Zone 3 – 15

Zone 4 – 15

Zone 5 – 28

Zone 6 – 0

All sites will be within the 10m-20m range of depth range with a minimum of 75% of sites within the 14m -18m range. This will ensure that the data reflects the practice of not wishing to dive too close to shore to avoid possible pollution sources and not wishing to dive too deep for diver safety reasons.

The sites are located by using random numbers to generate pairs of grid co-ordinates. The positions thus selected are plotted until the required number of sites has been allocated in each stratum. In the field, sampling sites are located by a global positioning system (GPS).

At each survey site, two divers, using underwater breathing apparatus, swim a 50m x 1m belt transect. The transect pairs are situated roughly in parallel either side of the stern quarters of the vessel at anchor.

Scallops down to 25mm or less in shell length (when measured in a straight line at the widest point across the shell) are collected and brought on board the research vessel. Scallops less than 90mm shell length are measured to the nearest millimetre and returned to the water as soon as practicable. Scallops that are 90mm and larger are retained.

This provides a number of scallops per 100m2 and size-frequency information for each site.

Page 12: Commercial Scallop Dive Fishery (Port Phillip Bay) · This Commercial Fishery Plan (Plan) relates to the Commercial Scallop Dive Fishery (Port Phillip Bay) (the Fishery), which is

12 | P a g e

On returning to port, retained scallops are weighed to provide a total whole weight retained and then each retained scallop is measured to the nearest millimetre and weighed. This provides information on the length-to-weight relationship for individual scallops of a harvestable size.

The licence holder must engage an observer (a person independent of the licence holder or associates) to oversee the survey who must travel on board the vessel during the survey and oversee the measuring and weighing in port. The observer must be approved by the Department prior to the survey commencing.

As noted earlier, this survey design represents a starting point and may be refined over time by the licence holder as data are collected to inform improvements. The Department will need to approve any modification to the initial design but, essentially, the following will apply:

• Once data have been collected, a statistician will be required to review the properties of the data and, where possible, to perform a power analysis to estimate how many survey sites would be required to obtain statistically significant comparisons over time;

• Replication should be such that precision (standard error/mean) does not exceed 25%, noting that Coleman (1998) estimated that the standard error of the mean for 70 stratified random sites was typically 15 to 30%; and

• The boundaries of historical strata must be maintained.

Two-tiered designs, where preliminary surveying is used to identify commercially viable sub-strata for more intensive sampling, may be considered for inclusion once initial baselines have been established. Although sub-stratification has merit in increasing the precision of abundance estimates, it may be substantially costlier than the standard approach, and caution is required to ensure that scaling the observed densities to estimate absolute biomass avoids creating bias that may inflate recommended TACC to unsustainable levels.

Fishery-independent survey analysis and assessment

The survey would provide information on density and size structure of sampled scallops. Using the size information and a known growth rate (Sause et al. 1987), the number of scallops that would be of harvestable size (i.e. 90mm or larger) in the season following the survey is predicted using a simple model based on the von-Bertalanffy growth equation (Gwyther and Burgess 1986).

It is likely that growth rates for scallops in Port Phillip Bay have changed over time so this is one area of research that could be voluntarily undertaken by the licence holder (see Additional (non-mandatory) data).

The estimated abundance of scallops per stratum is calculated as the mean number of scallops per square metre multiplied by the total area of the stratum. Estimating abundance this way allows for comparisons with historical data, which is useful because it provides the opportunity to compare the abundance predicted by the survey with the actual yield of the fishery in the season following the survey. Historically, the results of the dive surveys generally provided a high level of accuracy in predicting the quality of the following fishing season, although in some years high mortality and/or slow growth diminished their accuracy (Coleman 1998)

For the purpose of setting a TACC for the current fishery, the estimated abundance of scallops per zone, rather than per stratum, needs to be calculated. The estimated abundance of scallops

Page 13: Commercial Scallop Dive Fishery (Port Phillip Bay) · This Commercial Fishery Plan (Plan) relates to the Commercial Scallop Dive Fishery (Port Phillip Bay) (the Fishery), which is

13 | P a g e

per zone is calculated as the mean number of scallops per square metre multiplied by the total area of the zone. As zone boundaries were set to approximate strata boundaries, the number of sites set per stratum will be an appropriate number for zones.

The simplest way to then calculate biomass in each zone would be to use the scaled estimates of abundance for each zone and the mean weights from retained scallops (whole fresh weight per individual) from a range of size categories (90mm and larger) to estimate the percentiles of biomass in each category.

A proportion (e.g. 10 to 20%) of the average estimated biomass (of scallops 90mm or larger) for each zone would be set as the TACC. Setting the proportion at a relatively conservative level of 10 to 20% ensures sustainable harvest in the event of high mortality and/or slow growth (as observed during the historical dredge fishery). It also ensures, in combination with the size limits, that sufficient future reproductive potential is retained, and accounts for the vulnerability of scallops to fishing (sedentary and aggregated in beds).

Additional (non-mandatory) data

There is a unique opportunity to collect data at the commencement of fishing that will be invaluable in the future research and management of the species. Information from the start of exploitation provides a critical baseline of data against which the progress of the developing fishery can be compared. Failure to collect data at the outset can limit assessment options in the future, especially in any early stock reduction phase of the fishery.

It is, therefore, in the licence holder’s best interests to collect additional data at the lowest spatial scale possible (ideally, at the scale of each dive location) from the commencement of fishing.

The additional data that can be collected include:

• Additional details on catch and effort (recording dive depth, ascent time, descent time, GPS location and catch for each dive).;

• Size structure of the catch (measuring shell length - widest diameter in millimetres); and • Length-to-weight relationship for the catch (measuring shell length and weight of

individual scallops).

The additional details on catch and effort would, ideally, be recorded for each dive, while information on size structure and length-to-weight relationship would be recorded for part of the catch (sub-sample).

These additional data would need to be collected independently by the licence holder, either manually, or via electronic devices.

Additional data on effort can be collected via electronic dive profile loggers and the size structure of the catch can be collected via electronic GPS-enabled shellfish-measuring boards. The Victorian abalone industry has been using electronic measuring machines coupled with data storage loggers for many years and these devices are eminently suited to monitoring scallop catches.

Although not mandated, electronic data acquisition represents a low cost method for accurate and precise geospatial monitoring of commercial catch and effort. Hand-measured data is an

Page 14: Commercial Scallop Dive Fishery (Port Phillip Bay) · This Commercial Fishery Plan (Plan) relates to the Commercial Scallop Dive Fishery (Port Phillip Bay) (the Fishery), which is

14 | P a g e

acceptable alternative, but it will be slower, prone to operator error, and will incur additional labour costs associated with transcribing data from datasheets into an electronic database.

Other data can be collected to provide information on the status of the scallop resource in Port Phillip Bay and to provide inputs for various stock assessment models (see Level 3) but collecting these data requires the destruction of animals and/or experiments to be conducted. The Department can work with the licence holder to determine a suitable sampling strategy for these data, at the licence holder’s request.

These other data include:

• Age structure of the catch. This provides size-at-age information which is relevant to the setting of size limits;

• Growth. Growth rate was determined during the 1980s (Sause et al. 1987) but is likely to have changed in the intervening period. Growth rate information, in conjunction with survey data, is used to determine the TACC; and

• Meat weight of individuals (weight of adductor and gonad dried to a constant weight – 60oC for 48 hours) and the condition of the gonad (visual inspection). This provides information on the condition of scallops (i.e. suitability for harvest) which may affect the value of the TACC over the course of the fishing season. Monthly meat weight is one of the inputs for a per-recruit model.

Additional data analysis and assessment

Fishery-dependent geo-referenced catch and effort data logging provides highly resolved and accurate information that can be used to gauge the performance of the fishery in a spatially explicit manner. Spatial resolution is important because it provides information that can be used to address issues that may arise among competing user groups and supplements information about scallop distribution and abundance from fishery-independent surveys.

Detailed catch and effort data also provides a baseline from which target and limit reference points for performance indicator/s can be determined. For example, one performance indicator for the proposed Commercial Scallop Dive Fishery would be commercial catch rate (catch-per-unit-effort – CPUE expressed as kilograms of whole weight per hour of bottom time / per hour of vessel time at sea / per unit area). Reference points are values of catch rate at which a management response is required. For example, a Target Reference Point (TRP) is where the fishery aims to be and a Limit Reference Point (LRP) is where there is an unacceptable risk to the stock. Reference points are accompanied by decision rules (i.e. the TACC is automatically increased or decreased by a percentage) to ensure that there is clarity, transparency and reproducibility in the management response.

Information on the size structure of the catch (fishery-dependent) and of the population (fishery-independent survey) shows how many year groups are present in the both the population as a whole and in the harvestable proportion of the population. This indicates the future potential of the fishery. For example, fluctuations in recruitment may result in insufficient biomass to support the TACC from a preceding year, but this would be less likely if there are several cohorts in the fishery compared with relying almost exclusively on 1+ aged scallops, as was the case during the final years of the scallop dredge fishery.

The analysis and assessment of the survey and additional data must be undertaken by person/s with scientific capability, which may be the licence holder or person/s engaged by the licence holder. The Department requires that the data, analysis and assessment be audited prior to use in the broader assessment process (see Process for decision making). It is, therefore, in the licence holder’s best interests to ensure that the collection, analysis and assessment of fishery information is done correctly. The Department can provide ongoing guidance to assist in the process.
