Sustainability overview

Updated: December 2019 

Pink salmon are the biggest commercial salmon fishery in Alaska, followed by sockeye, chum, coho and then chinook. However, Alaska’s largest export salmon species to the UK is sockeye, followed by pink and then chum.

Pink salmon in Alaska are largely well-managed, their populations are generally in a positive state, and the fishery largely meets its objectives. However, management requires some improvement regarding monitoring and management of enhancement programmes (where hatchery-raised young salmon are released into rivers to bolster wild populations), particularly since pink salmon are one of the main fisheries that use enhancement in Alaska.

Most pink salmon are caught using purse seines and drift or set gillnets, with some caught using trolling or beach seines. Bycatch levels are generally very low and mostly include other salmon species. There is some interaction with endangered, threatened and protected species but this is generally very low, occurring in the gillnet fisheries. Most gears have a very limited impact on the habitat as most fishing gears for salmon have little interaction with the seabed, except for beach seines and set nets, which normally operate in areas with fine to medium substrates (that are not likely to be vulnerable).

Biology

Pink salmon, also called Humpback salmon (or humpy for short) are the smallest of the salmon species, but the most harvested. They have been caught for canning since the late 1800s. They start of life completely silver, turning bright greeny-blue with silver sides as adults, and turning colours again as they migrate back to their native rivers to spawn. They are named pink salmon after their pink flesh but are also named ‘humpy’ as the males develop a very large hump on their backs and hooked jaws when they return to the rivers in the spawning season. They feed on plankton, marine shrimp, krill, small fish, squid and aquatic insects; their predators include killer whales, bears and birds.

Pacific salmon occur from California north along the Pacific coast throughout the Pacific Ocean, Bering Sea and Arctic Ocean waters adjacent to Alaska. Pacific salmon are a shorter lived species and much more prolific breeders than Atlantic salmon.
Pink salmon have the shortest lifespan amongst the Pacific salmon, maturing and completing their life-cycle within two years, and have a rapid rate of growth. Although pinks are anadromous, they do not remain in freshwater for an extended period, and are also semelparous (typically die after spawning). Pinks spawn much closer to the ocean than most other Pacific salmon (usually within 30 miles of the river mouth). Females will lay 1200 to 1900 eggs between late June and early September, and the eggs hatch in late winter or early spring. Although pink salmon have low fecundity they produce large eggs which helps to ensure their resilience. As soon as they emerge from the gravel the fry migrate to the ocean and return to freshwater after 18 months to spawn.

Stock information

Pink salmon are the most abundant of the Pacific salmons. There is no concern for biomass, or for fishing mortality. Pink salmon are of medium resilience.

There are hundreds of salmon stocks in Alaska. They are grouped into Stock Management Units (SMUs). Within the MSC Alaska fishery, there are 10 main SMUs that are relevant to pink salmon (Southeast, Yakutat, Prince William Sounds, Lower Cook Inlet, Upper Cook Inlet, Bristol Bay, Norton Sound, Kodiak, Chignik, Peninsula/Aleutian Islands). Because there are so many stocks in Alaska, the stock assessments identify ‘index rivers’ as indicators to monitor abundance. These index rivers represent population levels in each of these SMUs. The target reference point (TRP) is based on escapement goals. When salmon hatch, they migrate from the rivers to the sea and when they become adults, they travel back to the rivers to spawn and are harvested along the way. To ensure that there are enough salmon to spawn and replenish the next generation, the Alaska Department of Fisheries and Game set limits on the amount of salmon that can be caught, which is called an escapement goal. A fishery is assessed on how well the TRP is met by reviewing how well the escapement goals have been met over the previous last decade.

Pink salmon have generally met or exceeded their escapement goals for the reference periods. Some underages (were escapement goals have not been met) occurred where lower levels of salmon occurred for some years in some stocks e.g. in Yukutat. The 2020 forecast for the Southeast stock shows that there have recently been poor levels of survival in marine and freshwater environments, leading to reduced harvests. This is thought to be due to drought conditions and recent changes in their sizes are attributable to a marine heat wave, followed by warm sea surface temperatures in 2014-2016. Fishery managers estimate and forecast salmon population sizes during salmon seasons and set limits accordingly to ensure that there are enough salmon left to spawn. There were no pink salmon Stocks of Concern in 2018 and there are no pink salmon listed on the Endangered Species Act.

Management

Criterion score: 0.25 info

The fishery is certified and largely well-managed as it largely meets its objective (to achieve escapement goals for the majority of the time). However, management requires some improvement regarding improved monitoring and management of enhancement programmes.

Alaskan salmon fisheries are managed nationally, by Alaskan state agencies (the Alaska Board of Fisheries (BOF) and Alaska Department of Fish and Game (ADFG); federally, by the North Pacific Fishery Management Council (NPFMC)) and internationally via the North Pacific Anadromous Fish Commission (NPAFC) and the Pacific Salmon Commission. Alaskan salmon are managed under Fishery Management Plan (FMP) under the Magnuson-Stevens Fishery Conservation and Management Act covering Chinook, Chum, Coho, Pink and Sockeye salmon. The BOF applies regulations to conserve salmon, such as quotas, open and closed seasons, bag limits, harvest levels and harvesting methods, which the ADFG implements.

The main method used to manage salmon is by ensuring they meet their escapement goals (see Stock Info tab). The ADFG conduct forecasts during the salmon season (called in-season management) to estimate how many salmon there are and the catch limits and open or close the fishery when needed. Salmon populations are monitored on a daily basis, using a variety of methods, including aerial surveys, weir counts, genetic studies, sonar, monitoring catches, their migration, escapement, hatchery contributions (often monitored real-time via otolith marking), habitat quality and environmental conditions. However, there are some data gaps, such as abundance, productivity and exploitation rates of component stocks of Susitna Sockeye salmon in the Upper Cook Inlet. Stock assessments are quantitative, conducted annually and reviewed every three years. The escapement goals act as reference points. Uncertainties are considered: some Stock Management Units (SMUs) such as Prince William Sound use risk-based methods to estimate escapement goals, however, other SMUs such as Kotzebue area, do not have adequate data to do this. There are three types of escapement goals, which accommodate for the type of fishery (commercial, sport or subsistence) and data availability. Biological Escapement Goals provide the greatest potential to reach Maximum Sustainable Yield. If stocks are consistently not achieving escapement goals and harvest levels, they are designated a Stock of Concern” (SOC), triggering stricter management, such as recovery plans. There are no pink salmon stocks of concern, two chum salmon and three sockeye. For sockeye, the efficacy of rebuilding is often unknown and timeframes are uncertain e.g. Upper Cook Inlet. Several areas listed stocks of concern that subsequently improved, and concern levels were lifted (e.g. in Bristol Bay). However, harvest strategies have not been entirely successful, as stocks in some SMUs have not been maintained throughout the reference period; some stocks remain stocks of concern (e.g. in Upper Cook Inlet).

Non-compliance in the salmon fishery and hatcheries is rare. Compliance is enforced by the ADFG, where fishers must record catches via fish tickets, which help fishery managers monitor harvests. The ADFG also monitor hatchery outputs as required in their non-transferrable permits, which limit the salmon species, volume that can be released into the fishery and specific sourcing information.”

Capture Information

Criterion score: 0 info

Salmon fisheries conducted in Alaska are generally very selective, with negligible bycatch rates. Most gear types used to catch salmon are designed to fish within the water column and do not interact with the substrate. Beach seines and set gillnets do however, have some interaction with the substrate. These gears are considered to have a low impact on the substrate as they are conducted in areas with fine to medium sediment type with a generally flat seafloor topography. Therefore, there is limited impact on the benthic environment for these gears. The US government agency monitoring interactions with Endangered, Threatened and Protected species concludes that the fishery does not pose a high risk to marine mammal species. However, there has been some interaction recorded by gillnets and beach seine gears, with some Alaskan salmon fisheries considered Category II fisheries, where some risk is considered to marine mammal species.

There is minimal unwanted catch in salmon fisheries. Catches almost exclusively comprise salmon species. Some other finfish are allowed to be retained for personal use (mainly steelhead), but this is considered to be negligible (in terms of volume). Apart from in the Southeast and Yakutat fisheries, non-salmonid species are not allowed to be retained and sold. There are cross-boundary stocks of salmon, shared between Alaska and Canada. The Pacific Salmon Treaty includes instruments to manage trans-boundary stocks, which have achieved their escapement goals in most years.

There are multiple measures in place to protect Endangered, Threatened and Protected (ETP) species, including the Endangered Species Act (ESA), the Marine Mammal Protection Act (MMPA) and the Migratory Birds Act (MBA). US government agencies (NMFS) monitor the state of ETP species and conclude that no salmon fisheries are considered high risk (Category I) to ETP species and that the interactions with ETP mammals are relatively low. Ten Alaskan salmon set and drift net fisheries were deemed Category II fisheries for their potential impact on marine mammal species. Two Alaskan salmon gillnet fisheries were listed as Category III, along with six seine (purse or beach) and one troll fishery. The species affected depend on the SMU, but generally include cetaceans, pinnipeds and otters. Category II indicates occasional incidental mortality and serious injury of marine mammals and Category III indicates a remote likelihood or no known incidental mortality or serious injury of marine mammals). NMFS does not consider there to be a significant number of interactions with ESA listed bird species. There are low levels of interaction between birds and the gillnet fisheries, but none of the species were listed under the ESA. In areas of overlap, they concluded the total number of birds exposed to gillnets in any of the overlap areas is small”. However, there are a lack of data to determine if the hatcheries have an impact on ETP species. More understanding is required on the impacts of gillnets, largely on seabird species. Greater observer coverage is required to fully determine the impacts on ETP species.

Multiple management measures are in-place to limit gear interactions and impacts with benthic environments. Hatchery programmes are monitored and managed under permits. Gear marking is required for all commercial fishing gear. In addition, Alaska state employs multiple management restrictions to protect waterways, which serve as important habitat to anadromous fish species. Through long-term habitat monitoring, the ADFG have not observed significant impacts on habitats from salmon fishing gear, and no significant impacts from gear loss. Essential Fish Habitats are designated to protect “habitat areas of particular concern” that salmon species rely on in Alaska throughout their life-history stages. This management is directed at Coho and Chinook salmon but chum and sockeye share similar habitats, so are likely to benefit. The impacts of the human activities on salmon is reviewed every five years. Whilst beach seines and set gillnets may interact with the benthic environment, they generally operate in areas where the substrate is fine to medium. Fishers are deterred from fishing in substrates that are not flat, and in areas with small biota and no seagrasses, as nets are more likely to snag on features. In addition, permits for beach seines are only provided in a three SMUs, including Yukon and Kodiak, where only a small number of permits are available. There are management measures to mitigate their impacts, including requirements to release King salmon and further gear restrictions such as mesh size, material and length limits and restrictions on when and where beach seines can be set. These fisheries do not operate in areas designated as Habitat Areas of Particular Concern.”
