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

Fishery Management Plan

3

• 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
• bjectives

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

• 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

Resource Analysis: Species Description

Fishery Background

• Oregon’s 2nd 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

• 1st ever shrimp fishery to be certified “sustainable”

by Marine Stewardship Council (MSC)

• Highly variable, environmentally forced recruitment

April to December: upwelling season Spring transition Early Spring: Eggs released

Resource analysis: Stock status (Recruitment)

Environmental events reflected in annual catch

Major ENSO events

• Instead, recruitment is more dependent on ocean

conditions (upwelling, larval transport, water temperature, etc.) # of spawners NOT closely linked to # of recruits

Resource Analysis: Stock status (Stock-recruit relationship)

Management objectives

10

• 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

Harvest management strategy: Fishery description

Biological Reference Points and Harvest Controls

12

June average shrimp catch/trip Current season will close Following season will open 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 exceeds 7.5 ft. As soon as possible April 15

• Designed to limit fishing when stock is

depressed

• Vetted through fleet in 2014 (73% support)

If this was in place, season would have:

• Closed early due to

persistently high sea level height (El Nino indicator) and low landings : 1983, 1984,

1998 (Blue)

• Curtailed season

– 1982 and 1995 (Green)

Shuts fishing down when depressed, gives best chance for rebound

FMP Summary

15

• 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
• bjectives

16

• Anadromous forage fish, common bycatch
• f shrimp fishery
• Listed as “threatened” under ESA in 2010
• NMFS 2017 eulachon recovery plan lists

“eulachon bycatch” as a “high” threat

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

Impact of footrope lighting

22

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

Need for footrope lighting requirement

23

• 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)

Footrope lighting summary

25

• 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

Staff Recommendation

26

Issue 1: FMP

• Adopt draft FMP

Issue 2: Footrope lighting devices

• Adopt OAR as described in attachment 3
