Sea Scallop Stock Enhancement in MaineA Fishing Community Based Project
Scott Feindel and Dan Schick, Maine Dept. Marine Resources
• Year 6 of a collaborative effort involving fishermen, community organizations, UMaine Sea Grant, and Maine DMR– Year 1 – Can spat be collected in Maine state waters?
– Year 2 – Scaling up the effort and selective monitoring of seeded areas
– Year 3 – Further expansion, monitoring, socio-economic issues
– Years 4 – 5 Decreasing involvement, questions about success
– Year 6 – DMR Scallop Advisory Council sponsors an Enhancement Workshop to establish direction
• Interest in scallop culture• Mix of systematic and trial and error approach• Low cost, volunteer-based• Integrating with DMR’s scallop monitoring programs
Maine’s Inshore Scallop Fishery
• Declining landings/ increased effort• Maine contributes only 2.5% of U.S. scallop supply• Higher day boat prices (but recent decline in price)• No license limitation / large amount of latent effort
– 889 draggers, 390 divers
• Season runs Dec 1- April 15• Most fishermen have permits for multiple species• Extensive areas of historically productive bottom

The reason Maine fishermen are interested in the project…
• Maine delegation sent to Japan
• Encouragement of enhancement activities and research– Coastal Research Priorities– Development Potential of Maine Scallop Industry Report
• Assessment of issues by local organizations– Cobscook Fishermans Association, Cobscook Bay
Resource Center, Stonington Fisheries Alliance, Northwest Atlantic Marine Alliance, Saco Bay Fisheries Alliance, University of Maine, UMaine Sea Grant, Maine Dept. Marine Resources, Beals Island Regional Shellfish Hatchery
Spat bag preparation
Setting the bags
Over-wintering
Releasing the scallops
Supporting the effort:Tagging
Site evaluation/ pre- and post-seeding surveys
Integrating with fishery monitoring
Developing Research
• 10% of seed to research - 3 sites/ year monitored in different areas– Saco Bay– Christmas Cove– Cape Jellison
• Regional efforts– GSI studies UMaine Machias– Systematic spat bag deployment– Brandeis University early genetics work
Tagged scallop on bottomat Cape Jellison seeding site
When the weather is good for enhancement work – it’s also good enough to go fishing….
• License surcharge, tax• Mandatory participation• Government subsidies• Aquaculture• Transient Gear
Issues/ Future Work
• May only succeed in certain local areas
• Large amount of latent effort
• Controversy over permit by rule and inclusion of transient gear scallop culture / project participants largely opposed to lease-based aquaculture because of perceived loss of fishing ground
• Economics of scallop culture may be problematic – added problem of PSP toxin in whole scallops
Conclusions
• Bottom-up approach
• Positive exchange of information between scientists and fishermen
• Value to science and management beyond stock restoration
• Technology exists and can be adapted to Maine’s waters
• Some form of ownership incentive may be important in the long run
