  1. Commercial Pink Shrimp Fishery Management Exhibit F January 19 th , 2018 Scott Groth, Pink shrimp project leader Marine Resources Program 1

  2. Why are we here? Issue 1: Proposed adoption of a Fishery Management Plan (FMP) Issue 2: Proposed requirement of the use of lighting devices on the footropes of shrimp trawls Eulachon smelt Ocean (pink) shrimp LED fishing light

  3. Fishery Management Plan • FMP designed to promote fishery sustainability • Describes species, fishery, and monitoring • Identifies trends, objectives, and priorities • Describes biological reference points and harvest controls • Adoption needed to meet state and MSC objectives 3

  4. What is a pink shrimp? • Ocean shrimp, bay shrimp, Pandalus jordani • Small, short lived shrimp found offshore only • Salad shrimp, shrimp cakes, shrimp cocktail Ocean (pink) shrimp

  5. Resource Analysis: Species Description • Very short lived (< 4 years) • Hermaphroditic • Carry eggs from November to April. • Live on soft bottom substrate 40-150 fathoms • Feed on copepods, euphausiids, etc. • Oregon is the center of their distribution

  6. Fishery Background • Oregon’s 2 nd most valuable state managed fishery (commercial only) • Semi-pelagic trawl fishery • Season= April 1- October 31 • Management and industry have worked closely to improve its sustainability • 1 st ever shrimp fishery to be certified “sustainable” by Marine Stewardship Council (MSC)

  7. Resource analysis: Stock status (Recruitment) • Highly variable, environmentally forced recruitment April to December: upwelling season Spring transition Early Spring: Eggs released

  8. Environmental events reflected in annual catch Major ENSO events 60 50 MILLIONS OF POUNDS 40 30 20 10 0 1960 1970 1980 1990 2000 2010 8

  9. Resource Analysis: Stock status (Stock-recruit relationship) # of spawners # of recruits NOT closely linked to • Instead, recruitment is more dependent on ocean conditions (upwelling, larval transport, water temperature, etc.)

  10. Management objectives 1. Maximize biomass yield while monitoring and addressing overfishing 2. Stable regulatory platform, maximum flexibility to fleet 3. Collaborate with fleet on research, share findings 10

  11. Harvest management strategy: Fishery description 60 50 MILLIONS OF POUNDS Annual 40 catch = 30 variable 20 10 0 1960 1970 1980 1990 2000 2010 50 TOTAL EX-VESSEL VALUE 40 (Millions of dollars) Value= 30 recent 20 increases 10 0 1980 1990 2000 2010 11

  12. Biological Reference Points and Harvest Controls • Designed to limit fishing when stock is depressed • Vetted through fleet in 2014 (73% support) June average shrimp Current season will close Following season will open catch/trip More than 12,500 lbs October 31 April 1 Less than 12,500 lbs October 15 April 15 Less than 10,000 lbs and prior April-January SLH As soon as possible April 15 exceeds 7.5 ft. 12

  13. Looking back on biological reference points 60 If this was in place, June Landings (100’s of pounds) Landings indicator 50 season would have: 40 • Closed early due to 30 persistently high sea 20 level height (El Nino 10 indicator) and low 0 landings : 1983, 1984, 1978 1981 1984 1987 1990 1993 1996 1999 2002 2005 2008 2011 2014 2017 1998 (Blue) • Curtailed season 7.75 Environmental indicator – 1982 and 1995 (Green) Sea Level Height (Apr- Jan) 7.5 Shuts fishing down 7.25 when depressed, gives 7 best chance for rebound 6.75 1978 1981 1984 1987 1990 1993 1996 1999 2002 2005 2008 2011 2014 13

  14. Industry support for FMP No Group n Yes No opinion Permit holders 15 67% 7% 27% Vessel operators 48 69% 8% 23% 14

  15. FMP Summary • FMP designed to promote fishery sustainability • Describes species, fishery, and monitoring • Identifies trends, objectives, and priorities • Describes biological reference points and harvest controls • Adoption needed to meet state and MSC objectives 15

  16. Issue 2: Footrope lighting devices • Anadromous forage fish, common bycatch of shrimp fishery • Listed as “threatened” under ESA in 2010 • NMFS 2017 eulachon recovery plan lists “eulachon bycatch” as a “high” threat LED fishing light Eulachon smelt 16

  17. Exclusion from a trawl 1 2 3 Before net entrainment In codend After entrainment Trawl door LEDs Escape hole BRD Net codend Bycatch Reduction Device (BRD) or “Shrimp grate” OFWC implemented a eulachon optimized ¾ ” in 2012

  18. Bycatch reduction timeline 2003-> Bycatch reduction devices (BRDs) required 2007-> First shrimp fishery certified “sustainable” 2010-> Eulachon listed “threatened” under ESA 2012-> OFWC implemented ‘eulachon optimized’ BRDs, which strongly reduced bycatch 2014-> LEDs discovered DRAMATIC reduction of eulachon bycatch (~ 90% ) 2017-> LED efficacy confirmed, amount of lighting better understood 18

  22. Impact of footrope lighting 2014- Huge population of eulachon LED use show 90% eulachon reduction! 100% voluntary use immediately 2017- Low population of eulachon Confirm dramatic eulachon reduction (85% ) Voluntary use reduced 22

  23. Need for footrope lighting requirement • As eulachon have been less prevalent, voluntary usage has decreased • Fishing mortality typically impactive when populations are depressed Voluntary compliance of LED use by year (from fleet surveys) 23

  24. Industry support for footrope lighting requirement No Group n Yes No opinion Permit holders 15 87% 7% 7% Vessel operators 56 74% 19% 7% 24

  25. Footrope lighting summary • Bycatch reduction research and industry cooperation have resulted in very low bycatch • LEDs are inexpensive and highly effective for bycatch reduction of eulachon smelt • Use of 5 LEDs/ net was highly effective (2017 research) • Voluntary use of LEDs has reduced in years when less bycatch encountered 25

  26. Staff Recommendation Issue 1: FMP • Adopt draft FMP Issue 2: Footrope lighting devices • Adopt OAR as described in attachment 3 26

  27. Acknowledgments • Bob Hannah and Steve Jones (ODFW retired) • Oregon’s pink shrimp industry • Oregon Fish and Wildlife Commission • MRP/ Fish division leadership • Matt Blume, Jill Smith, Kelly Lawrence, Craig Good (ODFW shrimp project) • Mark Lomeli (PSMFC) • Oregon Trawl Commission 27
