Nushagak-Mulchatna King Salmon Committee

Project Overview

Restrictions to the sport fishery due to low early season inriver passage of king salmon combined with sometimes intense fishing for sockeye in the Nushagak District in the mid-2010’s led to proposals to pair restrictions in the commercial and sport fishery. In response to the proposals and working with affected stakeholders, the board removed several triggers in the Plan to provide managers with more flexibility in managing this complex fishery with sometimes inaccurate escapement information.

During the December 2018 Bristol Bay Finfish meeting, the Alaska Board of Fisheries struck a committee to review Nushagak River fisheries and regulations, and to provide recommendations on a comprehensive solution to Chinook salmon management.  The Board charged the committee with reporting back. The Bristol Bay Science and Research Institute (BBSRI) committed to supporting the committee’s work through a stakeholder-led technical analysis of options for the committee to consider.

The BBSRI Study Team facilitated 16 committee meetings through 2022. The committee identified management challenges, measures of fishery success, management objectives, and changes to management plan action provisions during that time. On behalf of the committee, the Study Team submitted a regulatory proposal in April 2022 to the board to substantially change the management plan by inserting management objectives and regulatory changes and called for the development of a research plan to address problems with Nushagak king salmon stock assessment programs.

Throughout the 2022-2023 board cycle, the Study Team continued to work closely with the committee, the ADF&G and the Nushagak Advisory to arrive at a comprehensive, robust solution for king salmon management. After the board designated Nushagak River king salmon a stock of concern and the ADF&G submitted an Action Plan early in the regulatory cycle, these entities went to great effort, individually and cooperatively, to enhance management of this stock. As a result, the board adopted a new Stock of Concern Management Plan and sweeping changes to the existing management plan at the recommendation of the Study Team and Committee, and with broad support from the NAC, ADF&G, and stakeholders in March 2023.

Bristol Bay Board Meeting

Proposals 41 and 42 were submitted to the board to pair restrictions in the commercial and sport fisheries after restrictions to the sport fishery due to low early season inriver passage of king salmon combined with sometimes intense fishing for sockeye in the Nushagak District in the mid-2010’s. In response to the proposals, the board: · removed several triggers in the Nushagak-Mulchatna River King Salmon Management Plan that affected the sport fishery, to provide managers with more flexibility in dealing with sometime inaccurate information, · tabled Proposals 41 and 42, · created a special board committee to develop a comprehensive solution to Chinook salmon management, and · charged the committee with reporting back to the board at its March, 2020 Statewide Meeting. The Bristol Bay Science and Research Institute (BBSRI) committed to supporting the committee’s work through a stakeholder-led technical analysis of options for the committee to consider.

Spring 2019

Nushagak River King Salmon Committee Formed

The committee was originally comprised of board members Payton, Morisky and Ruffner. The board released a request for committee nominations of members of the public January 31, 2019. The board received 14 letters of interest from which they chose eight people to represent the stakeholder groups involved with the Nushagak River king salmon fisheries.

October 2019

First Meeting of the Committee

The committee first met in Anchorage on October 21, 2019, to get underway and present preliminary analyses of the fishery’s history and technical challenges associated with monitoring and managing the fishery. Committee members were provided a questionnaire about challenges and problems each saw with respect to king salmon management, what constituted success in their fishery, and what problems might be addressed by changes in the Plan and/or stock assessment programs. This meeting was distinct from subsequent committee meetings in that attendance was very large, and this was the only meeting attended by the board members.

December 2019 -

February 2020

Break-out Meetings

Subsets of the full committee met with the BBSRI Study Team in December 2019 (Anchorage; sport/commercial) and February 2020 (Dillingham; commercial, subsistence, sport). These break-out meetings produced initial lists of 1) the challenges faced by the Nushagak king salmon fisheries, and 2) what defined success from each stakeholders’ perspectives. The meetings also provided initial ideas for (3) possible management objectives to address challenges and meet measures of success in each fishery, and (4) possible regulatory actions and non-regulatory information or actions needed to achieve management objectives. The discussions identified much of the technical analysis for the Study Team to examine. COVID-19 precluded an in-person meeting for the entire committee scheduled for April 2020 in King Salmon.

February 2020

Formal Board Committee Disbanded and Follow-on Structure Determined

At the Upper Cook Inlet meeting in February 2020, the Board disbanded the formal committee and strongly encouraged stakeholders remaining on the committee to continue to work together in preparation for the next in-cycle Bristol Bay meeting in 2021. BBSRI reasserted its commitment to serve the committee and move toward its original mission outlined in the charge statement: a comprehensive solution to the Plan. The committee makeup remained the same as selected by the board initially on February 19, 2020, minus the board members.

December 2020 -

April 2021

Committee Meetings

The committee and subsets met 15 times between December 2019 and April 2022. Between meetings the Study Team pulled together committee work products and prepared goals, objectives, and agendas for follow-on meetings. Pandemic-related constraints on travel and in-person meetings precluded many of the committee meetings from being in person. The committee met via video conference December 17 and 18, 2020 to review the 2020 fisheries and refine challenges, management objectives, measures of success, possible action item, and non-regulatory information needs. The committee met again January 14, 2021, to review an early draft report describing the committee’s work and begin a focused review and discussion of possible regulatory changes to the Plan that would continue through March 2021. Subsequent meetings resulted in a refined list of possible management actions with consensus by the time the committee concluded for the winter. The Study Team met with ADF&G in April 2021 to discuss those management actions with consensus from the committee at the time.

January -April 2022

Committee Meetings

The committee reconvened in January 2022 to discuss and work toward a regulatory proposal incorporating actions with committee consensus and identify additional information or programs needed in addition to regulation changes (i.e., non-regulatory recommendations). The committee reviewed the 2021 fishing season, 2022 sockeye salmon forecast, updated tables from the Historical Report that included 2020-2021 data, and ADF&G input on the possible management actions under consideration by the committee. The Study Team presented and discussed with the committee 1) impacts of different management triggers for the Wood and Nushagak river to delay the onset of the commercial fishery in the Nushagak District, and 2) the effects of mesh size on exploitation rates. Other discussion topics included plans for BBSRI’s 2022 test fishery in the Nushagak District and input the Study Team had received from ADF&G concerning a Nushagak sockeye salmon management trigger. With input from ADF&G and the committee, the Study Team further refined the list of management actions to put forward in the form of a regulatory proposal in April 2022. The committee also raised issues to improve king salmon management that require action outside of the Nushagak-Mulchatna River King Salmon Plan, including improving inseason management and monitoring programs. Since some of the greatest fishery challenges/problems cannot be addressed by changes to the management Plan alone, the committee felt strongly that these should not be ignored in a search for comprehensive solutions. Hence, the inclusion of these non-regulatory recommendations in the committee’s work products.

September 2022

Historical Management Review

In September 2022 the BBSRI Study Team finalized Historical Review of Nushagak River King Salmon Management (Brookover 2022) after incorporating review comments received from committee members and ADF&G. The report was distributed to contributing ADF&G staff members, ADF&G Board Section and the NAC to serve as a historical reference for the upcoming board meetings. An earlier draft version was made available to, and used by, the NRKS Committee in 2019 for the same purpose. The final version was later submitted to the board record in November, prior to the scheduled Bristol Bay meeting (PC54).

October 2022

Board Work Session

Nushagak King Salmon Committee Report The BBSRI Study Team finalized the Summary of Outcomes from the Committee to Examine the Nushagak-Mulchatna King Salmon Management Plan, 2019-2022 (Brookover et al., 2022) and submitted it to the board’s record November 14, 2022, for the upcoming Bristol Bay meeting (PC53). The report documents the process and outcomes from the committee that ultimately led to the submittal of Proposal 11 directed at improving management, and non-regulatory recommendations aimed at improving stock assessment. ADF&G Action Plan On November 23, ADF&G finalized and submitted Nushagak River King Salmon Stock Status and Action Plan to the board (RC4). The Action Plan presented options for potential management actions for the commercial, sport and subsistence fisheries. It also presented research projects for Nushagak River king salmon, and proposed criteria for removing (delisting) the SOC status designation in the future Board Meeting Staff reports concerning Nushagak River king salmon at the Bristol Bay meeting were substantive, informative and, according to one board member, “refreshing.” Among the reports, staff provided information on the stock status of Nushagak king and sockeye salmon, escapement goal reviews for the same (and other) stocks, management of Nushagak River king salmon, results of a recent hooking mortality study conducted for Nushagak king salmon, a recently developed run reconstruction model, and a review of the recently submitted Nushagak River King Salmon Stock Status and Action Plan. Nushagak king salmon issues were not ripe for deliberation. The recent SOC designation, lack of availability of the pending ADF&G Action Plan, complexity of problems with king salmon management, “poor” state of king salmon stock assessment, and questions with several proposed management actions ultimately led the board to defer action to the March 2023 Statewide Meeting. Although regulatory action was deferred, much of the substantive information provided by the department for Nushagak River king salmon during the cycle was provided through the staff reports at the Bristol Bay meeting.

March 2023

Collaborative Meetings - Study Team, Committee, ADF&G, NAC

After the Bristol Bay Meeting, the Study Team met with ADF&G staff over numerous occasions to discuss elements in ADF&G’s proposed Action Plan for further consideration. The NAC met and discussed the Nushagak King Salmon Action Plan, Nushagak King Salmon Management Plan, and Proposals 11-13 on January 18 and again February 10. The NRKS Committee met in person twice to develop a solution considering the deferred proposals (11-13) and the Action Plan. On February 13, a meeting was held among committee members, ADF&G, and other interested stakeholders to discuss the concept of a separate “Stock of Concern Management Plan” and what elements might be in it, using modified draft conceptual language (Appendix D2) as a starting point. The committee also discussed changes to the existing management plan outlined in Proposal 11 and how the SOC Management Plan would mesh with it. The NAC Subcommittee met February 17 to discuss king salmon management including the ADF&G Action Plan, the draft SOC Management Plan and modified Proposal 11 contained in Appendix D3, and other topics. The subcommittee took one action to restrict mesh size in the commercial fishery to 4 ¾” until June 28. Other topics, including the WRSHA, were referenced for further discussion. On February 23, the NRKS Committee reconvened to refine language in both plans and strive for consensus on as many elements as possible. After the NRKS committee meetings were complete, the BBSRI Study Team used the consensus items to draft a revised version of Proposal 11 and the new SOC Management Plan. These versions were presented to the Nushagak AC at their March 1 meeting and the NAC voted in favor of both with three specific changes. The Study Team updated the plans to include NAC recommendations and submitted them to the board (RC13).

March

2023

Statewide Board Meeting

With specific exceptions, the SOC Management Plan and Revised Proposal 11 in RC13 had garnered consent from the NRKS Committee and the NAC in consultation with ADF&G. That consent was reflected early during the board meeting when staff referred to the plans therein as a good framework that would improve management, and in public testimony that recognized declines in Nushagak River king salmon, voiced impacts in the various fisheries, voiced support for acting now, and supported RC13, with specific exceptions, as the solution. Proposals 12 and 13 met with mixed support and opposition and less discussion. Consent on the language in RC13, with the stated exceptions, carried through board deliberations. The board amended the language to address the stated exceptions and include delisting criteria. In the end, the board approved the plans as amended, by a vote of 5-0. The board also adopted a finding for the record concerning the adoption of OEGs in the SOC Management Plan. The board took no action on Proposal 12 given the action on the SOC Management Plan and Proposal 11, and failed Proposal 13 0-5.

He also participates subsistence fishing.  ​ Robert also serves on BBSRI's Board of Directors.

Study Team Members

The three-person Study Team, sponsored by BBSRI, led and facilitated the committee process, prepared project analyses and project reports.

Committee Products

As a starting point for discussions at the early committee meetings, members were asked to identify the current challenges to, or problems with, fishery management pertaining to the Nushagak River king salmon fisheries. The focus was on challenges or problems related directly to the NMKSMP, but the discussion was not limited to challenges pertaining narrowly or only to the Plan. Ultimately, the committee identified six key challenges faced by the Nushagak River king salmon fisheries. These challenges and problems are described below and form the foundation for subsequent committee discussions.

Fishery Challenges

As a starting point for discussions at the early committee meetings, members were asked to identify the current challenges to, or problems with, fishery management pertaining to the Nushagak River king salmon fisheries. The focus was on challenges or problems related directly to the NMKSMP, but the discussion was not limited to challenges pertaining narrowly or only to the Plan. Ultimately, the committee identified six key challenges faced by the Nushagak River king salmon fisheries. These challenges and problems are described below and form the foundation for subsequent committee discussions.

Spatial and temportal overlap in distribution of king and sockeye salmon in Nushagak Bay

Managing a mixed-stock and mixed-species fishery with stocks and species of differing productivity, in addition to overlapping timing and spatial distribution of stocks and species, is a fundamental challenge in the Nushagak District commercial fishery. King salmon are caught incidentally during the commercial fishery for sockeye salmon, which makes harvesting available abundant sockeye salmon stocks while protecting weak king salmon runs difficult.

Factors that may affect this challenge include:

  • when the first commercial openings for sockeye salmon are scheduled

  • when the fishery opens relative to the tide stage

  • how and when continuous[1] fishing occurs

  • selectivity of gillnet mesh size.

The NMKSMP directs the department to keep the commercial fishery for sockeye salmon closed until the projected escapement into the Wood River exceeds 100,000 fish. The Nushagak drift and set net allocation plan (5AAC 06.368) guides commercial fishing time for each gear type during the sockeye salmon fishery.

 

[1] Questions arose as to what continuous fishing means. For committee purposes, continuous fishing meant a continuous period, from a certain point in time to the end of the season, when the commercial fishery is opened to drift nets, set nets, or both gear types until further notice or for the remainder of the season. It was distinct from intensive fishing. Intensive fishing, as discussed by the committee, meant fishing on an every-tide basis beginning at a certain point in time to the end of the season. Intensive fishing, unlike continuous fishing, is managed by emergency order daily and is characterized by repetitive fishery openings of a certain number of hours in duration, e.g., 10-hour periods. 

High uncertainty surrounding king salmon fishery assessment 

Particularly information from the inriver sonar program, lack of a rigorous king escapement goal, and lack of being able to develop any preseason indication of king run strength.
This challenge, like the first, was raised as an issue at every committee meeting held.

Uncertainties associated with the current king salmon assessment program estimates have limited the understanding of the king salmon stock, available yield, and fishery performance.

The accuracy of commercial catch estimates, including age-size-sex, is limited.

“Dropouts” in the commercial fishery are unaccounted for in the annual run accounting.  

Catch-and-release mortality in the sport fishery is not factored in to estimates of mortality associated with sport fishery.

Catch and escapement age-sex-size characteristics in are not well measured or understood, and confidence in the accuracy of the inseason and post-season sonar-based estimates of inriver abundance has declined as research has examined assumptions made in the program.

 

Without substantive improvement in these areas, and particularly with inriver abundance and escapement estimates, the development of brood tables is compromised and with it, the ability to produce robust escapement and inriver goals, pre-season forecasts and inseason inriver abundance projections.

Given the inaccuracy of assessment data, committee members felt the Plan remains too narrowly prescriptive. While the Board of Fisheries reduced the number of inriver abundance-based triggers in the Plan at the December 2018 meeting, some felt the ability to manage for even two triggers (55,000 and 95,000 fish) was questionable. Similarly, fishery management decisions are based on highly inaccurate inriver run estimates. 

Costly impacts from inseason restrictions 

Impacts from inseason restrictions are costly to the different fisheries but vary in important ways. 

Sport Fishery
In the sport fishery, complete inseason closures have had very large economic impacts for what was seen by most as likely modest biological benefits. Inseason closures have entirely precluded the ability to fish, typically for the remainder of the season. Closures carry obvious impacts to anglers, but also carry high costs, i.e., cancellations, to sport fishing businesses for the season, and negatively effect bookings for following years. In turn, the number of king salmon protected from harvest or incidental mortality by closures during years of low inriver abundance is low, i.e., in the hundreds or low thousands of fish.  Unlike the commercial fishery, it is not possible to close and then re-open the guided sport fishery without substantial impacts to the fishery.

Commercial Fishery
In the commercial fishery, the directed fishery for king salmon had remained closed in 8 of the last 10 seasons. Closures in the sockeye fishery to conserve king salmon late in the season had disproportionately higher costs in terms of foregone sockeye harvest, with a lower gain in king salmon conservation than restrictions applied earlier in the season.

Subsutence Fishery

The subsistence fishery has a statutory priority over other fisheries. Reducing the inriver subsistence fishery to less than 7 days per week when the projected escapement falls below 55,000 fish potentially jeopardizes the ability of the fishery to achieve amounts necessary for subsistence (ANS) of salmon.

Conservation Inequities
The burden of king salmon conservation has varied among fisheries (stakeholders), years, and run sizes. The fisheries, as well as the stocks, are somewhat separated in time and along the migratory path which can lead not only to king salmon conservation issues but to unequal burdens for conservation as well. 
In small king salmon runs, the sport fishery had typically borne the greater burden of conservation through inseason fishery restrictions in July while current management plans focused on prosecuting the commercial fishery. Inseason closures, as implemented in the sport fishery during 1999 and 2010, represent a very large impact on the guided sport fishery operators. When management allows for pushes of sockeye to move into the escapement in June with the intention of protecting kings and there are no subsequent restrictions to the sport fishery, it could be argued the commercial fishery has borne a greater burden of conservation.  In any event, the separation in space and time for when each fishery is restricted can lead to unequal sharing of the conservation burden.

 

Recent declines in abundance, size and returns per spawner 

Declines in abundance, size and returns per spawner of king salmon over the past 10 years have raised biological concerns and caused increase fishery restrictions. 
King salmon runs have gotten smaller in recent years, causing an increase in the number and severity of inseason restrictions in the commercial, sport and subsistence fisheries, and resulting the escapement goal not being achieved in several years.

Based on existing data, king salmon productivity (returns per spawner) appears to have decreased. King salmon have also been getting smaller in size. Committee members asked how this affects the reproductive potential of a given number of king salmon spawners in terms of egg deposition, and whether the escapement goal needs to take these runs of smaller fish into account.

Large sockeye runs and low king returns

The recent dynamic produced by the combination of Challenges #4 and #5 together resulted in both foregone harvest of early season sockeye salmon and hindered achieving the king salmon escapement goal. It has also exacerbated Challenge #1 above. 

In an unfortunate positive feedback effect, recent large sockeye returns to the Nushagak District have influenced Bay-wide drift boat fleet dynamics that have created unprecedented fleet sizes (>600 drift vessels), which has further increased early season harvest rates over historical rates, and negatively affected any attempts to limit catch of king salmon in the commercial sockeye fishery. To further amplify this phenomenon, late sockeye runs in recent years to Bristol Bay’s Eastside districts (e.g., Egegik and Naknek) can attract almost half the entire Bay’s drift fleet to the Nushagak District.

Clarity and implementation of Plan provisions

Several points pertaining to specific provisions of the Plan arose in meeting discussions. First, some felt the basis for the inseason Nushagak River king salmon escapement and inriver abundance projections was not clear. For example, it wasn’t clear whether the Plan intended to use projected inriver returns in some provisions and projected spawning escapement in others, or whether the use of the different terms was intentional.

It was also not clear how inseason projections are made, i.e., what data is used in projecting inriver returns and escapement. Committee members also stated that the method for estimating the projected sockeye escapement into the Wood River under NMKSMP provision (e)(1) was not clear, as previously mentioned under Challenge #1.

Measures of Success

After discussing the fishery challenges faced by the Nushagak River king salmon fisheries at the initial meetings, committee members were asked to discuss what constitutes success in their various fisheries; what conditions would need to be met for them to consider the fishery successful?

Inriver abundance and catch opportunity in the sport fishery. 

Consistent fishing opportunity for king salmon was emphasized as an important attribute of a successful sport fishery. Consistent inriver abundance, as a given year’s run timing allows, is needed to provide the opportunity to catch (and harvest) fish.

There was recognition that the pulsatile nature of the inriver run produces inconsistent levels of abundance throughout each season, and that natural fluctuations in run size create inconsistencies in abundance between years.

However, abundance is important for a successful fishery.

 

Ideally, success would equate to a catch rate of 2 large king salmon or more per day/angler. The opportunity to catch fish, or fishing success, is just as important and goes together with the next measure toward a achieving a successful fishery.

​To provide for consistent sport fishing opportunity, it is important that the king salmon fishery remain open throughout the 3-4 weeks from mid-June to mid-July. The ability to “have a line in the water” during this time was more critical to success than, for example, achieving high catch rates in all weeks and all seasons.

It is important that such an open fishery is predictable and consistent both within a season and from season to season. However, an open fishery alone doesn’t necessarily result in a successful fishery.

Measures of Success

Inriver abundance and catch opportunity in the sport fishery. 

Consistent fishing opportunity for king salmon was emphasized as an important attribute of a successful sport fishery. Consistent inriver abundance, as a given year’s run timing allows, is needed to provide the opportunity to catch (and harvest) fish. There was recognition that the pulse nature of the inriver run precludes consistent levels of abundance through all parts of each season, and that natural fluctuations in run size hamper consistent levels of abundance among years. However, abundance as the natural pulses allow are important for a successful fishery. Ideally, success would equate to a catch rate of 2 large king salmon or more per day/angler. The opportunity to catch fish, or fishing success, is just as important and goes together with the next measure toward a achieving a successful fishery.

Predictably open season.

To provide for consistent sport fishing opportunity, it is important that the king salmon fishery remain open throughout the 3-4 weeks from mid-June to mid-July. The ability to “have a line in the water” during this time was more critical to success than, for example, achieving high catch rates in all weeks and all seasons. It is important that such an open fishery is predictable and consistent, or could be counted on, both within a season and from season to season. However, an open fishery doesn’t, by itself, necessarily result in a successful fishery. 

Harvest opportunity.

Ideally, opportunity for anglers to harvest one or more king salmon (any size) would help to fully define success in this fishery. However, this is not as important as the ability/opportunity to fish for king salmon provided by the first two measures above and is the least important of the three. 

Access to a directed commercial fishery for king salmon fishery when a harvestable surplus of king salmon exists.

The productive capacity of the Nushagak king salmon has fluctuated in the past and has the potential to support a viable commercial fishery.  

Access to available surplus sockeye salmon subject to addressing other concerns, including but not limited to: sustaining the king salmon population, avoiding a line fishery, obtaining escapement throughout the season, attaining allocation goals among gear groups, and ensuring annual harvest rates do not reach excessively high rates (e.g., >85-90%).

Management Objectives

Provide consistent sport fishing opportunity within and among seasons. This includes a level of inriver abundance as a given year’s run timing allows, and a predictably open season.

Provide a directed commercial king salmon fishery when surplus is available.

This will require changes to king salmon stock assessment programs to include the production of a robust preseason forecast and inseason and post-season escapement estimates. These, in turn, will require robust estimates of age-specific returns, i.e., brood tables, and improved accounting of the inriver run.

Provide for an uninterrupted commercial sockeye salmon fishery (i.e., minimize disruptions to the sockeye salmon fishery).

Conducting the early season fishery conservatively will minimize the need for costly late-season king conservation measures. The concept of conservative early season fishing was initially suggested as a separate management objective but later combined here due to its similarity with this objective.

The department shall manage the commercial and sport fisheries in the Nushagak District as follows: … reasonable opportunity for subsistence harvest of king salmon. Note: This is language currently included in the NMKSMP.

The subsistence fishery is the last fishery to be closed.

Achieve escapement goals for all species in the district.

While this is a biological objective, it was raised as an important objective for both the sport and commercial fisheries. All felt it imperative to achieve goals and thereby ensure sustained salmon stocks and fisheries. In addition to providing high levels of yield, or production, achieving the inriver goals for Nushagak River king salmon was felt by sport fishery representatives to achieve the measures of success identified above. In other words, achieving the inriver goals generally provides for the consistent inriver abundance needed for a successful fishery.

Maintain a representation of age classes in the escapement similar to the run. 

This is currently implied as an objective in the NMKSMP under subsection (b)(2). It was generally discussed to be relative to a given year’s run (i.e., strive to achieve an age and size composition in the escapement that is like the return to the district).  Committee members believed that it was not intended to be used to strive to achieve historical age class representations each year (i.e., differentially harvest specific ages in a given year’s return to match the historical or average age compositions in the escapement).
