1. Bay Scallop FMP Draft Amendment 1 Marine Fisheries Commission Aug. 12, 2010 Investigating Adaptive Management of Bay Scallop Harvest Based on Measures of Abundance

2. Background Bay scallop FMP finalized Nov 2007 Prohibited take occurred from 2006 – 2008 as part of the FMP management strategy Data on scallop abundance from the fishery independent sampling are evaluated annually as directed by the FMP Sampling in Core, Bogue, and Back sounds began to show an increase in abundance beginning in 2008

3. Target Re-opening Indicator A standardized scallop population level indicator was selected as a target for reopening the harvest season by the N. C. Marine Fisheries Commission at its January 2009 meeting This target was based on NCDMF sampling that occurred between the months of October and December in 1984 and 1985 for Back, Bogue, and Core sounds

4. Annual Commercial Landings 1950 to 2005

5. Progressive Triggers Allows flexibility in management Allows consideration of population variability in all areas each year Allows for limited bay scallop harvest while maintaining the FMP goal of rebuilding the stock to pre-red tide abundance levels

6. Back Sound Sampling Target (1984-85 lnCPUE) and Progressive Triggers for Adaptive Management

7. Bogue Sound Sampling Target (1984-85 lnCPUE) and Progressive Triggers for Adaptive Management

8. Core Sound Sampling Target (1984-85 lnCPUE) and Progressive Triggers for Adaptive Management

9. Additional Items to Consider Proclamation authority allows flexibility to adjust seasons, trip limits or allowed gears based on current conditions 5-year review of the FMP in 2012 Daily maximum allowed harvest is 20 bushels per person per day with a maximum of 40 bushels per day in any combined commercial fishing operation (15A NCAC 03K.0501)

10. Additional Items to Consider Recreational harvest limits are now set in proclamation Separation of gears and user groups to particular days of the week for easier enforcement Increase in commercial fishing effort due to improved harvest and open license Number who harvest bay scallops for recreational purposes is unknown

11. Management Options 1.Status quo: Continue using only target opening indicators, without progressive triggers for adaptive harvest 2. Consider adaptive management measures based on pre-determined progressive triggers for Core, Bogue, and Back sounds 3. Consider adaptive management measures for Pamlico Sound based on limited sampling with pre-determined progressive triggers

12. Management Options 4. Use pre-determined target and progressive triggers from Bogue Sound for opening areas south of Bogue Sound until a sampling time series is developed for a starting target level from this region 5. Continue to leave areas south of Bogue Sound closed to bay scallop harvest but consider adaptive management measures once a sampling time series is established to determine a target opening level

13. No public comments were received during any of the open meetings Overview of Public Meetings NCDMF received comments from a special meeting with Mr. Henry Frost, Mr. Joey Frost and Dr. Pete Peterson CommitteeAC InitialDMF InitialCrafted Own Northeast Shellfish H&WQ Southeast Central Inland

14. Other Items from Meetings Use of dish detergent to improve visibility of scallops to hand harvesters Study the impacts of hand harvest versus scallop dredge harvest on grass beds Change the definition of a scallop dredge to a scallop scrape Reinforce the need for a recreational shellfish license

15. AC and NCDMF Recommendations Consider adaptive management measures in Bogue, Back, and Core sounds using progressive triggers of 50%, 75%, and 125% of the 1984-1985 target levels Consider adaptive management measures in Pamlico Sound using progressive triggers of 50%, 75%, and 125% of the January 2009 target level

16. Use adaptive management measures with progressive triggers from Bogue Sound as a proxy to open areas south of Bogue Sound until a sampling time series is established for an appropriate target in the areas south of Bogue Sound AC and NCDMF Recommendations

17. Recommended Commercial Harvest Levels for the Progressive Triggers

18. Recommended Recreational Harvest Levels for the Progressive Triggers

19. Research Recommendations Expand the current bay scallop fishery independent sampling to improve estimates of the population abundance and spawning condition of the stock Conduct research to study the impacts of scalloping activities on bay scallop habitat
