1. An overview of the 2014 Gulf of Maine cod stock assessment Michael Palmer Northeast Fisheries Science Center National Marine Fisheries Service 166 Water St. Woods Hole, MA 02543 Maine Fishermen’s Forum Rockport, ME March 6, 2015

2. Major signals in the fisheries independent and dependent data Fishery Catches have declined since 2011 (quota reductions) Truncation in the size/age of the catch Occurrence of large fish (>80 cm) are now largely absent from the recreational fishery Catches remain concentrated in the western Gulf of Maine Some eastward shift in commercial catches since 2013 Surveys Survey indices have declined to the lowest levels of the time series Not only NEFSC surveys, but also MA DMF and ME/NH surveys Truncation in the size/age of survey catches Cod resource remains highly concentrated in the western Gulf of Maine Percent occurrence of cod has declined

3. Mean age Truncation in the age structure evident in both fishery-dependent and independent data Reductions in the mean age

4. Recreational fish size Annual MA DMF saltwater fishing derby http://www.mass.gov/eea/agencies/dfg/dmf/recreational-fishing/saltwater-fishing- derby.html http://www.mass.gov/eea/agencies/dfg/dmf/recreational-fishing/saltwater-fishing- derby.html Minimum qualifying criteria: Weigh-in: 30 lb (13.6 kg) ~ 107 cm Catch-and-release: 42 inches (107 cm) There have been no entries since 2011 Figure courtesy of S. Correia

5. Commercial fish size Commercial landings Proportion of commercial landings by market category shows decline of ‘large’ cod Large fish (>110 cm) are much less common in the ‘large’ market category compared to 7-8 years ago.

6. Commercial catch efficiency Commercial LPUE indices have declined sharply since 2010. Declines since 2010 are likely due to several factors including decreases in cod abundance, availability and quota

7. Commercial catch distributions Beginning in 2013 and continuing in 2014, there was an eastward shift in the distribution of GoM cod catches

8. Commercial catch and effort redistribution Catch efficiency of cod is greater in the western Gulf – if industry wanted to avoid targeting cod, one way to do it is to shift effort into the eastern Gulf Declines in proportion of GoM cod catch from the western Gulf coincided with an easterly shift in the spatial distribution of the groundfish fleet’s fishing effort

9. Survey distributions Reductions in the spatial extent/frequency of occurrence of cod in the Gulf of Maine

10. Survey distributions Last 8 years (2007-2014): Continued reductions in the spatial extent/frequency of occurrence of cod in the Gulf of Maine

11. Regional survey indices Declining regional survey indices (NEFSC, MA DMF, ME/NH)

12. Assessment model results Recruitment continues to be poor 2009-2013 geometric mean M=0.2: 1.5 million M-ramp: 2.7 million Fishing mortality >1.0 since at least 2011 >5 times overfishing threshold Spawning stock biomass has declined to 2,000-2,500 mt 3-4% of SSB MSY
