1. 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

2. Marine (97%) Coastal zone Estuaries Continental shelf The Aquatic Environment - >70% of earths surface Freshwater (< 3%) Rivers Resevoirs Lakes Ponds

3. Typical shellfish on-growing environment

4. European shellfish production from 1995 - 2004 EU shellfish production is static or declining

5. 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

6. 1. OVERSTOCKING Examples: Arcachon, France – Pacific oysters Bantry Bay, Ireland – mussels

7. 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)

8. Carrying capacity definitions and SMILE SMILE solution Physical Bathymetry, morphology: GIS models Current speed and direction: Delft3D Model ProductionIndividual shellfish growth: ShellSIM, WinShell models Population growth: D3D-ShellSIM- EcoWin2000 framework EcologicalEcosystem response - plankton, nutrients: E2K Model Wild species, reefs: E2K-GIS resource partitioning. Watershed management strategies: SWAT-E2K SocialThe 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

9. Modelling framework Run Delft 3D 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 E2K using (I) current and bathymetry data (ii) WFD (iii) aquaculture distribution Use D3D to calculate water fluxes across these larger boxes at 30m intervals, and at the seaward boundary of the lough domain – supply these offline as spreadsheets Hydrodynamic transport simulated in E2K by reading these spreadsheet files during an E2K model run Prepare a water quality database including both the individual lough and inputs from freshwater and ocean boundaries (measurements) Enter larger box areas, volumes etc from GIS into E2K Run full E2K model, calibrate and validate 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 Measure individual shellfish growth rates in the field Implement individual growth model in E2K, test, and then add population dynamics Extract E2K initial conditions for state variables in each box, boundary conditions and calibration data Delft3D EcoWin2000 ShellSIM Management scenarios

52. 9 themes - 78 indicators

53. 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

54. 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. Response of European Mollusc Producers to CONSENSUS

55. 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

62. Challenges for RTD/Industry cooperation European aquaculture probably still suffers from the European ‘paradox’.

63. 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.

64. Off-shore production is possible, but dilution not the answer! Future research topics?

65. 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

66. 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
