Key Performance Metrics

11

• Total recirculating flow per system: - Quarantine and Growout = 99%

- Purge = 90%

• Influent consumption rate:- 23% system replacement/day

- Maximum daily system water exchange rate:

Quarantine = 37%

Growout = 20%

Purge = 263%


Key Performance Metrics

12

• Culture tank exchange rate:- Moderately adjustable

- Quarantine = 30 min; Growout = 45 min; Purge = 45 min

• Delta Dissolved Oxygen:- Compares inlet DO to outlet DO

- Ranges from less than 1.5 mg/L in purge to more than 6 mg/L in quarantine

- No change in dissolved oxygen within the tanks

- Concentration at the tank outlet (100% of saturation) is perceived by every fish in all parts of the tank

Proposed FSB RAS systemAbove grade FSB RAS system

Harvest

16

• Expected harvest size between 3 and 6 kg

• Fish handling technologies include:- Pump and grade 600 g smolts as they leave the quarantine

system and are distributed to growout tanks

- Move fish within the growout tank module and into the purge tank module by swimming rather than pumping

- Trial use of grading nets and screens

- Inducing fish movement through water flow, light, bubble nets, etc.


Harvest

17

• Fish held for up to 10 days in non-recircirculating water to purge potential off-flavours, and starve

• Fish harvest technologies include:- Purge tank dewater fish pipe processing area

outside biosecure rearing environment

• Trial of pre-harvest chilling is planned


Financial

18

• Expected capital cost

$23 / kg live weight of annual production

$28 / kg HOG

• Production cost$7.60 / kg HOG


Project Budget

19

Capital ($K) - Civil works & main building 1,659- RAS systems 3,437- Design 479 - Other equipment 310 - Total $5,885 K

Operating ($ / kg HOG)* • Feed 2.25• Labour 1.46• Smolts 0.58• Energy 0.74

* Preliminary estimates prior to completion of detailed design


Unique Challenges

20

• Permitting- DFO in flux due to jurisdiction transfer- Lack of well-developed aquaculture regulations

• Species- Atlantic salmon: non-native species

• Multiple funders

• Effluent- Understanding risk and mitigation of disease transfer

via effluent and groundwater


Environmental Monitoring

21

• Aquaculture license

• Canadian Environmental Assessment Agency (CEAA) screening

• Independent Environmental Monitoring Plan (IEMP)


Lessons Learned

Partnership and collaboration

Technical Advisory Committee

23

• The Salmon Aquaculture Innovation Fund at Tides Canada is supported by a multi-stakeholder Technical Advisory Committee

• The role of the TAC is to:

- Evaluate and make recommendations on project funding applications

- Review interim and final reports provided pursuant to funding agreements

- Aid in the dissemination of the research outcomes from funded projects


Performance Matrixes

24

• To support the consistent and comparative reporting of information, the TAC has developed a comprehensive set of performance metrics in the following key areas:

- Production - Productivity

- Environmental - Financial

- Social

• Within each key area the following are defined:- Parameter / indicators to be measured

- Units

- What to measure

- Frequency

- Methodology


Performance Matrixes

25

• The consistency and comparability of reporting is supported by the multiple funding agencies and projects that have adopted these performance metrics in their funding reporting requirements

• Aquaculture Innovation Workshops are a key means to share information and results

• Through the support of the Tides Canada, the Freshwater Institute has funding to support closed containment projects in B.C. to the end of 2013


Future Milestones

26

• Secure all funding

• Hire Operations Manager

• Complete detailed design drawings

• Start construction

• Intake of first smolts

• Atlantic salmon BBQ and celebration!
