Pacific cod

Pacific cod in the Bering Sea is abundant and not subject to overfishing.There are four Pacific cod stocks in the north Pacific. In the east, they are: Aleutian Islands (AI), Bering Sea (BS), and Gulf of Alaska (GOA). In the west is the Bering Sea (West) and Chukotskaya, Karaginskaya & Petropavlovsko-Komandorskaya subzones stock. This rating covers the eastern Bering Sea.A small fishery for east BS Pacific cod began in the 1960s. It grew to over 240,000 tonnes in 2016 but has since declined. In 2024, 127,000 tonnes were caught.The most recent stock assessment was published by NOAA in 2024 using data up to 2024. The approach to setting targets and reference points for the stock varies depending on which tier the stock is listed as. They also vary from one year to the next, depending on the most recent stock assessment data.The BS stock is Tier 3b, indicating there are some data limitations, but there are reference points for biomass and fishing pressure.Female spawning biomass has fluctuated over the years, reaching a high of around 300,000t in the 1980s, and then declining to below 250,000t in the 1990 and 2000s. In 2024 it was projected to be 223,107 tonnes. This equates to 39% of the biomass that would exist in the absence of fishing (B39%). It is above the proxy for Maximum Sustainable Yield with regard to biomass, which is B35% for Tier 3 stocks. Spawning biomass is projected to decline slightly to 215,747t in 2025 (B38.4%) and 206,498t in 2026 (B36.7%), but will remain above MSY proxy. The stock is therefore not in an overfished state.The proxy for Maximum Sustainable Yield with regard to fishing mortality is the overfishing limit (OFL). For 2024, it is set at 0.46, declining to 0.43 in 2025 and 0.41 in 2026. The Acceptable Biological Catch (ABC), which is used to decide catch limits, is calculated as a proportion of the OFL, and was 0.37 in 2024. This equates to a catch of 167,952 tonnes. The total catch of Pacific cod has been less than the OFL in every year since 1993. Estimated catch in 2024 was 127,097 - below ABC and therefore below OFL. Therefore, the stock is not subject to overfishing.

A number of management measures are in place and compliance is good. Catches are below scientifically recommended limits. The majority of the fishery is Marine Stewardship Council certified, although certification is conditional on making some improvements.There are three Pacific cod stocks in the eastern north Pacific: Aleutian Islands, Bering Sea, and Gulf of Alaska. They are managed by the North Pacific Fishery Management Council. There are two separate but complementary fishery management plans (FMPs) for them: the Bering Sea and Aleutian Islands (BSAI) Groundfish FMP and the Gulf of Alaska (GOA) Groundfish FMP. The FMPs cover a number of species, which are managed using various measures to protect stocks and ecosystem. These include catch limits and spatial and temporal closures.The BSAI and GOA fishery is Marine Stewardship Council certified. In 2023, 85% of the total BS catch was by certified fisheries. The certification is conditional on developing clear, fishery-specific objectives.The BSAI cod fisheries mainly happen in US waters and are managed by the National Marine Fisheries Service (NMFS). Stock assessments are carried out regularly. The overfishing limit (OFL), equivalent to the Maximum Sustainable Yield, is based on the estimated stock biomass. Catch limits are based on the Acceptable Biological Catch (ABC), which is set below the OFL. This keeps catch limits below the level at which the stock would be put at risk. Management therefore appears to be following scientific advice and is responsive to stock status.There is a federal and a state fishery. The ABC is divided between the two: the federal fishery is limited by a Total Allowable Catch (TAC) and the state fishery is limited by a Guideline Harvest Level (GHL). In 2024, the GHL was set at 8% of the ABC, equating to 20,154t. The TAC was set at 147,753. The combined limits are near equal to the ABC of 167,952t. Total catch by both federal and state fishery was 127,097t, which was below the ABC. From 2019-2023, combined limits have been set near equal to ABC, and average catches have been 98% of it, in 2024 catches were approximately 76% of the ABC. Therefore, the fishery appears to be complying well with catch limits.Stock assessments and management advice are based on a tiered system, where Tier 1 indicates the most data rich, and Tier 6 is the least. The BS stock is Tier 3b, indicating that there are reference points. There is a low risk that the ABC could exceed the OFL.Other management measures include spatial and temporal closures. There are bycatch limits to protect juveniles and species of concern, such as Steller sea lions, chinook salmon and herring.In the Bering Sea and Aleutian Islands, all vessels in the groundfish fisheries must also have a Federal groundfish license and carry scientifically trained observers (100% observer coverage) who monitor bycatch. Onboard observers, dockside monitoring, and electronic monitoring systems ensure compliance. Fishermen must retain their entire catch of Pacific cod - it cannot be discarded at sea. This improves accuracy of catch data.Some of the east Bering Sea stock may occur within Russian waters, although connectivity between the areas seems uncertain. Catch data was supplied by Russia in the past, but as of March 2022 NOAA reports that it is no longer available. Harvest rates in Russian waters were thought to be low, but this is now more difficult to monitor.

Some Bering Sea cod is caught by potting. There are some interactions with seabirds and marine mammals, but this is not thought to be a threat to populations.Pacific cod in the Bering Sea are caught by longline, trawl, pot and jig. Potting accounted for around 23% from 2019-2023.Information about the effect of the pot fishery on seabed habitats is scarce, but impacts are considered to be minor.Management measures include seasons, gear restrictions, and multiple area closures. Certain locations only permit the use of trawling gear while fishing for Pacific cod, and vessels employing hook-and-line gear must comply with restrictions regarding seabird avoidance. Gear standards include biodegradable panels in pot gears.According to MSC reports, Pacific cod accounted for 98% of the average pot catch from 2014-2018. Bycatch is small, and includes yellowfin sole, yellow Irish lord, great sculpin, other large sculpins, and octopus.Bering Sea pot fisheries take very few seabirds. Northern fulmars are the most commonly taken, with an average of 189 birds per year, followed by auklets (24) and the occasional murre (3). At these levels, removals are not expected to affect populations.The Bering Sea and Aleutian Islands Pacific cod pot fishery is listed as a Category III fishery under the Marine Mammal Protection Act (remote likelihood of/ no known interaction) for harbour seal (in Bristol Bay) and humpback whale in the Central North Pacific and Western North Pacific. This indicates that annual mortality and serious injury is less than 10% of any stock's Potential Biological Removal (PBR), or is by itself responsible for the annual removal of less than 1% of every stock's PBR. The fishery is therefore not resulting in overexploitation of these species.Management measures have been implemented to protect the direct and indirect impact on Steller sea lion, for which cod is a prey species. These include establishing fishery exclusion zones around rookery or haul out sites, phased-in reductions in the proportions of the catch that can be taken from critical habitat, and additional seasonal TAC releases to disperse the fishery in time.
