RECOMMENDATIONS

CATCHERS & REGULATORS

1. Work actively to address and close out conditions placed upon the certification of the fishery in the agreed timeframe.
2. Report achievements publicly to share progress with buyers.

RETAILERS & SUPPLY CHAIN

1. Monitor the progress in closing out conditions placed upon the certification of the fishery and if agreed timelines are met.
2. Express your support to help meet conditions that may be at a government/regulatory level (where applicable).

Fisheries

Within FishSource, the term "fishery" is used to indicate each unique combination of a flag country with a fishing gear, operating within a particular management unit, upon a resource. That resource may have a known biological stock structure and/or may be assessed at another level for practical or jurisdictional reasons. A fishery is the finest scale of resolution captured in FishSource profiles, as it is generally the scale at which sustainability can most fairly and practically be evaluated.

The score is ≥ 8.

There is a single escapement goal in place for the most productive coho-bearing watershed, the Nushagak. This goal, which was discontinued in 2006, was reinstated in 2012. There were also formerly escapement goals for coho salmon in the Togiak and Kulukak Rivers (Baker et al. 2006) of Bristol Bay. However, goals these goals have not been in place since 2006, when all coho salmon escapement enumeration projects in the district were also discontinued (Baker et al. 2006). The Nushagak district produces the majority of the coho salmon harvested in Bristol Bay (Sands 2009), with a significant percentage of the harvest also coming from the Togiak and Egegik districts (Jones et al. 2012). Harvests from other districts represent less than 10% of the Bristol Bay commercial coho salmon harvest based on recent 10-year averages. Overlapping run timing with pink salmon, which are both more abundant and typically of greater commercial interest, can put coho salmon at risk of over-exploitation. However, funding limitations force managers to prioritize monitoring projects, and fisheries with relatively less harvest pressure are passively managed. The Nushagak River coho monitoring sonar project resumed in 2012 to monitor achievement of the escapement goal (Tim Sands, ADF&G, personal communication).

DATA NOTES

Scores appearing at the region level reflect the range of scores for the district profiles in the region for each of the five FishSource scoring criteria.  District profiles are scored according to the complete FishSource salmon scoring method, which can be downloaded here. A summary of the method’s scoring criteria for district profiles follows below (for the Alaska/PSC troll fishery component, scroll further to see a slightly modified set of criteria applied to mixture pool fisheries).

The FishSource sustainability criteria as applied to salmon: Criterion 1. Management Responsiveness (Is the management strategy precautionary?) 1.1 Over the last decade, has fisheries management exhibited in-season responsiveness to stock status? 1.2 Has fisheries management responded appropriately over the last 15 years when/if the stock has failed to meet management objectives and/or maintain yields? 1.3 Has management exhibited responsiveness to concerns regarding the conservation and restoration of the stock’s essential freshwater, estuarine and coastal habitats during the last ten years? Criterion 2. Management Guidelines (Do the managers follow scientific advice?) Have appropriate escapement goals or operational equivalents been developed and implemented for the fishery’s wild stocks? Criterion 3. Adequacy of Data (Do fishers comply?) 3.1 Is a portion of harvest attributable to illegal, unreported, or unregulated fishing, resulting in official harvest data that is lower than the actual catch? 3.2 Is the fishery’s harvest adequately and accurately measured and reported? 3.3 Has escapement been adequately and accurately measured and publicly reported? Criterion 4. Stock Status (Is the fish stock healthy?) 4.1 Have escapement measures for the fishery’s wild stocks been maintained above escapement goals or thresholds, or have harvest rates been below the target harvest rates? 4.2 Has the catch trend been level or increasing over a 15-year period? Criterion 5. Are hatcheries or other enhancement activities negatively affecting wild stocks? (Will the fish stock be healthy in the future?) 5.0 Do hatcheries account for 10% or less of the fishery’s total production, or are hatchery-produced fish not in substantial contact with wild salmon? If “no,” then the following sub-criteria are analyzed: 5.1 Are managers able to manage for the (wild) stocks in a fishery that also contains hatchery stocks of salmon? 5.2 Is there a low quantity of hatchery strays in the escapement throughout the freshwater habitat of the wild stock, and is hatchery straying quantified by means of a technically sound data collection and analysis? 5.3 Over the past 10 years, have hatchery strays, hatchery out-plants, or any returning hatchery-produced fish been intentionally allowed to mix with the wild stock during spawning? 5.4 Are there active and effective policies that (1) establish objectives for the conservation of wild salmon, (2) put into place operational systems that limit hatchery impacts on wild stocks, (3) grant sufficient oversight and authority over individual hatchery programs to management agencies, and (4) establish a hatchery evaluation system that monitors the performance of individual hatcheries against wild salmon conservation objectives?
