Research as a driver for the development of the shellfish sector – a European perspective Gavin Burnell Aquaculture and Fisheries Development Centre, University College Cork, Ireland
The Aquatic Environment - >70% of earths surface Freshwater (< 3%) • Rivers • Resevoirs • Lakes • Ponds • Marine (97%) • Coastal zone • Estuaries • Continental shelf
Typical shellfish on-growing environment
EU shellfish production is static or declining European shellfish production from 1995 - 2004
Some of the reasons for this include: • Overstocking • Disease • Lack of natural spat supply • Invasive species • Poor performance of hatcheries • Public health issues (HABS, sanitation etc) • Lack of sites / conservation issues
1. OVERSTOCKING Examples: • Arcachon, France – Pacific oysters • Bantry Bay, Ireland – mussels
SMILE - Objectives 1. To establish functional models at the lough scale, describing key environmental variables and processes, aquaculture activities and their interactions; 2. To evaluate the sustainable carrying capacity for aquaculture in the loughs, considering interactions between cultivated species, targeting marketable cohorts, and fully integrating cultivation practices; 3. To examine the effects of overexploitation on key ecological variables; 4. To examine bay-scale environmental effects of different culture strategies. (Joao Ferreira, AFBI, IMAR)
Carrying capacity definitions and SMILE solution Physical Bathymetry, morphology: GIS models Current speed and direction: Delft 3 D Model Production Individual shellfish growth: Shell. SIM, Win. Shell models Population growth: D 3 D-Shell. SIMEco. Win 2000 framework Ecological Ecosystem response - plankton, nutrients: E 2 K Model Wild species, reefs: E 2 K-GIS resource partitioning. Watershed management strategies: SWAT-E 2 K Social The SMILE team has addressed this in China at the system scale, and in ECASA at the local scale using the FARM model. Not explicitly considered in SMILE
Delft 3 D Run Delft 3 D for large domain (Western Irish Sea and four loughs) using a fine grid (each lough has hundreds of cells) Define larger boxes (<50) within the loughs with GIS for E 2 K using (I) current and bathymetry data (ii) WFD (iii) aquaculture distribution Use D 3 D to calculate water fluxes across these larger boxes at 30 m intervals, and at the seaward boundary of the lough domain – supply these offline as spreadsheets Hydrodynamic transport simulated in E 2 K by reading these spreadsheet files during an E 2 K model run Modelling framework Eco. Win 2000 Enter larger box areas, volumes etc from GIS into E 2 K Implement individual growth model in E 2 K, test, and then add population dynamics Run full E 2 K model, calibrate and validate Management scenarios Extract E 2 K initial conditions for state variables in each box, boundary conditions and calibration data Measure individual shellfish growth rates in the field Shell. SIM Simulate individual shellfish physiology using a raceway model Use results to conceptualise an energy budget model for individual growth Implement and validate individual growth model in Stella or other simple modelling package Prepare a water quality database including both the individual lough and inputs from freshwater and ocean boundaries (measurements)

2. DISEASES Examples: • Summer mortality in Pacific oysters – France • Abalone viral Ganglioneuritis - Australia
INTERREG 3 A: Summer mortality of the Pacific oyster Crassostrea gigas in the Irish Sea Culloty, S. 1 Cotter E. 1, Malham S. 2, O’Keeffe S. 1, Lynch S. 1, King J. 2, Latchford J. 2, Beaumont A 2. 1 Dept. Zoology, Ecology & Plant Science, Aquaculture & Fisheries Development Centre/ERI, University College Cork 2 School of Ocean Sciences, Centre for Applied Marine Sciences, University of Wales, Bangor
Conclusions: Multi-factorial causes of Summer Mortality High H 2 O Temperatures Phytoplankton Blooms Increased food consumption Nutrient Enrichment Bacterial breakdown Reduced O 2 + Oyster O 2 demands = Excessive Gonad development Oyster Stress Herpes virus Vibrios Summer Mortality

3. LACK OF NATURAL SPAT SUPPLY Examples: • Mussel seed – Irish Sea, Netherlands • Pacific oyster – French Atlantic coast

The Irish Sea mussel seed fishery (tonnes) Ø 2003 – 35, 236 Ø 2004 – 24, 147 Ø 2005 - 14, 861 Ø 2006 - 23, 544 (source – DCMNR, BIM, DARD)
Seed supply limited by conservation issues Waddensea Coastal zone Delta
4. INVASIVE SPECIES Examples: • Manila clams – Italy • Pacific oysters – Netherlands
Introduced farmed species may “naturalise” and displace native species, eg. Manila clam in Italy
5. Public Health Concerns • Harmful algal blooms • Dioxins • Sewage

Strategic objective « to provide and demonstrate to consumers the benefits of high quality, safe and nutritious farmed fish and shellfish grown in sustainable conditions »
9 themes - 78 indicators
The 17 shellfish sustainability indicators 1. Improve recognition of public health benefits 2. Economically sustainable shellfish production 3. Improved quality of industry statistics 4. Ensure the availability of skilled work force 5. Strengthen/diversity the market 6. A development plan for sustainable shellfish aquaculture 7. Protect and improve environmental resources used by producers 8. Keep within the carrying capacity of the ecosystem 9. Sufficient hatchery supply of spat 10. Sustainable use of natural spat 11. Transparent site selection process for production 12. Adoption of Best Management Practices 13. Communicate the environmental and socio-economic benefits 14. Encourage use of extractive species in polycuture 15. Well informed consumers 16. Improvement of legislative tools and regulation processes 17. Sustainable shellfish aquaculture prioritised by EU
Response of European Mollusc Producers to CONSENSUS The EMPA position appeared to be that they could not accept the majority of the 17 Indicators, as several were the responsibility of non-farm operators, would not recommend development of any Code of Conduct within the framework of CONSENSUS, and proposed, as cultivated molluscan shellfish are naturally ‘organic’, that no recommendation on the issue of eco-labelling for such products should be written into CONSENSUS. 24 th April 2008.
The Working Group members reviewed all 17 Indicators, and concluded that : - they continued to represent the most appropriate measures of sustainability for the European molluscan shellfish sector - their continued validity should be formally endorsed; It was agreed that there was a clear role for industry representatives and trade associations to play, in lobbying for improved legislation, upgraded pollution prevention, greater recognition of the sector’s marginal environmental impact, more appropriate implementation of Regulations and Directives, etc. .

EAS opportunities & challenges • Further diversify membership – More from industry sector – Develop membership in CEE countries – strengthen its student forum • Increase cooperation through communication – with other aquaculture partners – with consumer organisations • Euroshell – a new network of shellfish researchers (Aad Smaal, IMARES) www. easonline. org
Challenges for RTD/Industry cooperation • European aquaculture probably still suffers from the European ‘paradox’.
• Producers need to look at the big picture and consider issues like sustainability and climate change • Scientists need to review success measurements that are based only on peer-reviewed, high-impact journals. Both need to have common fora to promote contacts and align industry needs with research programming.
Future research topics? Off-shore production is possible, but dilution not the answer!
Better use of resources through integrated multi trophic aquaculture eg use of molluscs and seaweeds to reduce nutrient load from agricultural run-off, sewage, and fish farms
Research will support shellfish production by: • Security and quality of seed • Optimising use of space - tools • Reducing risks to the consumer • Acceptance as a green industry
