  1. Southern Flounder FMP Amendment 1 NC Marine Fisheries Commission August 12, 2010

  2. Overview • Background • 2005 FMP and 2009 Stock Assessment • Life History • Commercial and Recreational Fisheries • Environmental Factors • Management Issues and AC and NCDMF recommendations

  3. Background • 2005 FMP recommended management measures to end overfishing, reduce bycatch, and alleviate user conflicts • 30% overall harvest reduction needed to achieve sustainable harvest • Projected overall harvest reduction of 17.2% from MFC selected management measures • Reassess the stock after 3 years • Commercial landings decreased and recreational harvest remained near time series high after FMP implementation

  4. Background • 2009 stock assessment: overfished & overfishing • Sustainable harvest based on achieving spawning potential ratio (SPR) of 25% (F threshold = 0.59) • (2005 FMP F threshold = 0.57) F (2007) = 0.75 • Further harvest reductions needed to achieve sustainable harvest • Harvest reductions based on projections that achieve sustainable harvest by 2015 • Overfishing to end 2 years after FMP adoption

  5. Life History • Live up to age 9+ and grow as large as 20+ pounds • Females grow larger than males • Spawn in ocean (November-February) • Juveniles in estuaries first two years of life

  6. Commercial Fisheries • 89% of total annual landings (1991-2007) and averaged 3.3 million pounds per year • Since FMP implementation, only 75% of total annual landings (2005-2007) and averaged 2.2 million pounds per year • 96% of landings from pound nets, gill nets and gigs • Pound nets were historically the top gear but landings surpassed by gill nets in 1995

  7. Recreational Fisheries • Harvested by hook and line, gigs and gill nets • Average annual hook and line harvest increased from 113,000 pounds/year (1991-1999) to 309,000 pounds/year (2000-2007) • Annual Recreational use of Commercial Gear License (RCGL) harvest less than hook and line harvest with big decline from 2002 to 2007

  8. Environmental Factors • Southern flounder use a wide range of coastal habitats which all serve critical functions throughout their life history • The Coastal Habitat Protection Plan (CHPP) focuses on fish habitat and threats to habitat • 26 recommendations in this FMP are specific to southern flounder

  9. Issues Ten principal management issues in 3 main categories: • Sustainable Harvest • Conflict between Fisheries • Bycatch of Undersized Southern Flounder and Protected Species

  10. Achieving Sustainable Harvest Establish harvest reductions that end overfishing in 2 years and rebuild the spawning stock biomass by 2015

  11. Management Options Commercial Recreational Status quo 15-inch size limit Season closure Reduce the 8 fish creel limit • Status quo (sea turtle lawsuit settlement) • Static/dynamic quotas • 15-inch size limit • Overall season closure • Gear season closures • Trip limits • 5.75-inch minimum mesh size for large mesh gill nets and pound net escape panels

  12. Research Recommendations • Investigate the feasibility of a quota as a management tool for the commercial southern flounder fishery • Annual survey of the recreational gig fishery (underway)

  13. AC and DMF Recommendations • Commercial: Status quo (large mesh gill net management measures implemented by sea turtle lawsuit settlement), which results in an overall commercial harvest reduction of 22.2% • Recreational: Increase the minimum size limit to 15 inches and decrease the creel limit to 6 fish, which results in an overall recreational harvest reduction of 20.2%

  14. Ocean Harvest of Southern Flounder The impact of the ocean harvest of older, larger, and predominantly female southern flounder to the stock

  15. Management Options • Status quo • Management measures specifically for the ocean flounder fisheries that reduce adult harvest of southern flounder

  16. Research Recommendations • Further research on southern flounder remaining in ocean after spawning • Determine exact spawning locations • Further otolith microchemistry research • Tagging study in ocean • Update southern flounder maturity schedule • Sample ocean spear fisheries

  17. AC Recommendation • Status quo—no additional commercial and recreational regulations specifically for ocean caught flounder DMF Recommendation • Status quo and address the research recommendations

  18. Large Mesh Gill Net -Related Conflicts User conflicts that occur between large mesh commercial gill net fishermen and recreational anglers and between large mesh gill net fishermen and other users

  19. Management Options • Status quo • Maximum yardage limit reduction • Limitations on how large mesh gill nets are set • Daytime attendance • Season closures • Nursery area restrictions • Mediation • Area/coast-wide management measures

  20. AC and DMF Recommendations • Status quo—implement mediation and proclamation authority to address user conflicts associated with large mesh gill nets

  21. Minimum Distance betweenPound Nets and Gill Netsin Currituck Sound Competition for space between pound nets and gill nets in Currituck Sound

  22. Management Options • Status quo (200-yard minimum distance) • Implement 500-yard minimum distance in Currituck Sound from August 15 through December 31

  23. Research Recommendations • Increased fish house sampling of the Currituck Sound flounder gill net and pound net fisheries • Increased at-sea observer trips with gill netters and pound netters in Currituck Sound

  24. AC Recommendation • Implement a 500-yard minimum distance between gill nets and pound nets in Currituck Sound north of the Wright Memorial Bridge (US Highway 158) from August 15 through December 31 DMF Recommendation • No recommendation

  25. Explore the Elimination of the RCGL Determine if the elimination or phase-out of the RCGL is appropriate

  26. Management Options • Status quo • Elimination of the RCGL • Prohibit the use of gill nets by the RCGL • Prohibit the use of shrimp trawls by the RCGL

  27. Research Recommendations • Reestablish a RCGL survey to obtain harvest and discard estimates • Establish an at-sea observer program of the RCGL fishery

  28. AC Recommendation • Status quo regarding the RCGL license until there are data indicating a negative influence on southern flounder and support the NCDMF research recommendations as well as a survey of SCFL holders who are inactive to collect data on what SCFL holders are doing with their licenses DMF Recommendation • Status quo and address research recommendations

  29. Update on Southern Flounder Bycatch in the Crab Pot Fishery Update of information available on southern flounder bycatch in the crab pot fishery

  30. Management Options Reduce Flounder Bycatch Minimize Ghost Pot Mortality Status quo Require degradable material in crab pots • Status quo • Require flatfish escapement devices on crab pots

  31. Research Recommendations • Formulate a bycatch estimate of southern flounder from crab pots • Further research degradable materials to determine which works best in a given water body and how other parameters, such as microbial activities and light penetration impact degradation rates and performance of the crab pot • Further research flatfish escapement devices that minimize undersized flounder bycatch and maximize the retention of marketable blue crabs

  32. AC and DMF Recommendations • Status quo and expand research on flatfish escapement devices and degradable panels under commercial conditions to other parts of the state to evaluate existing and alternative designs, degradation rates, and estimate the retention rate of legal sized blue crabs and the cost to crab pot fishermen

  33. Southern Flounder Discards in the Recreational Hook and Line Fishery Release mortality of southern flounder in the recreational hook and line fishery and its potential impact on the stock

  34. Management Options • Status quo • Implement regulations on terminal tackle used to fish for southern flounder • Implement a summertime season closure to the recreational southern flounder fishery

  35. Research Recommendations • Further research on factors that impact release mortality of southern flounder in the recreational hook and line fishery • Research on deep hooking events of different hook types and sizes on southern flounder

  36. AC and DMF Recommendations • Status quo and expand research on factors impacting the release mortality of southern flounder and on deep hooking events of different hook types and sizes on southern flounder

  37. Incidental Capture of Protected Species in Southern Flounder Large Mesh Gill Net and Pound Net Fisheries Management actions for NC’s commercial large mesh estuarine flounder gill net fishery and flounder pound net fishery addressing incidental capture of protected species

  38. Management Options • Status quo • Request funding for state observer program • Apply for Incidental Take Permit for large mesh gill net fisheries • Continue gear development research to minimize protected species interactions
