This Pacific Coast Steelhead Management Meeting delves into the history, management objectives, future directions, and critical questions that need addressing in the realm of steelhead management. Discussions focus on tribal co-management, ESA listing, hatchery fish, and regulatory compliance to maintain healthy steelhead populations. The meeting aims to review and modify the Steelhead Management Plan, incorporate recommendations for hatchery practices, and manage genetic diversity. Attendees will explore strategies for diversifying recreational opportunities, setting escapement goals, and minimizing the impact of hatchery-origin fish on wild populations.

Pacific Coast Steelhead Management Meeting What Are Managers Required to Provide Their Constituents? March 9-11, 2004 Bob Leland
Steelhead Management • History • Management objectives • Where we are going • Some questions that need addressing • Summary
Boldt Case Area • Tribal co-management • No ESA listing • Little supplementation of wild fish
Southwest Washington • No tribal co-management • Lower Columbia ESU steelhead were listed as “threatened” in March, 1998 • Wild Steelhead Release regulations initiated in 1986 for most of the ESU
Upper Columbia and SnakeUS vs. Oregon • Tribal co-management • ESA Listed as “Threatened” (3/98) and, in the Upper Reaches of the Columbia, “Endangered” (8/97) • Catch and Release (Wenatchee) in 1983 • Wild Steelhead Release for Upper Columbia in 1987, and in 1985 for the Snake River Basin • Section 10 Permit to Manage Excess Artificially Propagated Steelhead to Enhance Natural Origin Populations (10/03)
Steelhead Management • History • Management objectives • Where we are going • Some questions that need addressing • Summary
Management Objectives • Maintain healthy wild runs • Provide hatchery fish for harvest • Allocate harvestable surplus • Provide diversity of opportunity • Federal legal requirements • Co-management with Tribes
Management Objectives • Management by river systems • Estimate runsizes – wild fish focus • Set escapement goals • Monitor fisheries and escapement • Implement in-season management actions
Steelhead Management • History • Management objectives • Where we are going • Some questions that need addressing • Summary
Review and Modify the SHMP • Complete SHMP in 2 yrs, under SEPA • Work with staff, constituents, advisory group and tribes • Escapement goals • Diversity of recreational opportunities • Hatchery production • Develop regional plans for diversity of opportunity and recovery needs
Review and Modify the SHMP • Incorporation of Hatchery Scientific Review Group (HSRG) Recommendations • Wild steelhead/salmonid mgt. zones, sanctuaries • Segregated Management Programs (discrete gene-pool that is segregated, genetically & reproductively, from natural spawners) • Use locally-adapted hatchery (early-timed) segregated broodstocks • Manage the hatchery stock to maintain early spawn timing
Review and Modify the SHMP • Incorporation of Segregated Program Recommendations continued: • Smolt release & adult harvest strategies that have minimal impact on wild populations • Mark all released hatchery-origin fish to max. harvest, assess stray rates and assess genetic risk to natural stocks • Release fish in a manner to minimize straying & opportunities for natural spawning • Returning hatchery adults constitute < 5% of natural spawners
Review and Modify the SHMP • Incorporation of Integrated Program Recommendations (maintain genetic characteristics of “wild” fish among hatchery-origin fish) • Good hatchery practices • 10-20% of broodstock is composed of natural-origin spawners • Determine proper size of hatchery programs releases based on goals of stock • < 1/3 of natural origin escapement should be hatchery-origin adults • Control hatchery spawners through harvest, trapping, etc.
Steelhead Management • History • Management objectives • Where we are going • Some questions that need addressing • Summary
Some Questions That Need Addressing • Returning hatchery segregated stock adults constitute < 5% of wild spawners • Determine proper size of hatchery programs releases based on goals of wild stock
Some Questions That Need Addressing • Hoh River – segregated stock • Esc. goal for wild = 2,400; 5 yr avg. = 2, 700 • Early timed smolt release target = 100,000 • Hatchery harvest 5 yr. avg. = 2,800 • @ 70% harvest rate = 4,000 hatchery runsize • 1,200 hatchery fish, potentially spawning with wild • @ 90% harvest rate = 3,100 hatchery runsize • 300 hatchery fish, potentially spawning with wild
Some Questions That Need Addressing • Hoh River - segregated stock continued – • @ Wild esc. goal = 2,400; only 120 hatchery should have potential to spawn with wild • @ 5 yr. avg. wild esc. = 2, 700; only 135 hatchery should have potential to spawn with wild • Too many hatchery fish have the potential to spawn with wild fish • From 180 to 1,080 hatchery fish • Too many early-timed fish!
Some Questions That Need Addressing • Can efficient enough traps be put into streams to remove excess hatchery fish? • Can methodologies be developed to better estimate total hatchery run sizes? • Should early-timed hatchery release numbers be lowered or totally eliminated? • Can both tribal and recreational fisher desires be addressed? • Economic/Social – tribal and recreational • Cultural – full season; November to March/April
Some Questions That Need Addressing • For integrated programs < 1/3 of natural origin escapement should be hatchery-origin adults • Determine proper size of hatchery programs releases based on goals of natural stock
Some Questions That Need Addressing • Hoh River – (numbers from current targets/data) • Esc. goal for wild = 2,400; 5 yr avg. = 2, 700 • Integrated stock smolt release target = 100,000 • Integrated stock harvest 5 yr. Avg. = 2,800 • @ 70% harvest rate = 4,000 integrated stock runsize • 1,200 integrated stock fish, potentially spawning with wild • @ 90% harvest rate = 3,100 integrated stock runsize • 300 integrated stock hatchery fish, potentially spawning with wild
Some Questions That Need Addressing • Hoh River continued – • Wild esc. goal = 2,400; @ < 1/3 up to 800 integrated stock fish could have potential to spawn with wild • 5 yr. avg. wild esc. = 2, 700; < 1/3 up to 900 integrated stock fish could have potential to spawn with wild • At 100,000 smolt release target, number of integrated stock fish that may spawn with wild fish is: • From 300 to 1,200 fish – is with-in/close to HSRG targets • Looks real good on paper!
Some Questions That Need Addressing • Will there be funding for facility improvements/ new facilities to implement properly? • Can efficient/weather resistant traps be put into streams to remove/separate excess hatchery fish? • Can methodologies be developed to better estimate total hatchery returns/run sizes? • Will funds be available to monitor the harvested portion of run? • What actually is harvested; wild/hatchery?
Some Questions That Need Addressing • What is left to spawn? • Hatchery or wild, and in guideline proportions? • We do not currently know? Hatchery fish esc. estimates are mostly mathematical • Can both tribal and recreational fisher desires be addressed? • Economic/Social – tribal and recreational • Cultural – full season; November to March/April • Non-selective gear used by tribal & non-treaty fishers, may have greater impact to wild than hatchery portions of run? Mortality estimates difficult to derive.
Some Questions That Need Addressing • Need to start over on pre-season estimations of tribal and sport impacts • After 25 years, have it nailed down • Within the up to 33% hatchery fish allowed to spawn with wild, what will the impacts be, 20 or greater years from now? How do we avoid a potential genetic monster? • How will the new hatchery/wild interactions be determined under this new set-of-rules? • We’ve learned a lot about early timed hatchery steelhead and their genetic impacts on wild.
Steelhead Management • History • Management objectives • Where we are going • Some questions that need addressing • Summary
Summary • WDFW has a lot of steelhead management history. • Maintaining wild fish is the top priority • Hatchery fish are for harvest • Provide opportunity for tribes and sport fishers • New SHMP will be completed in 2 years • How will HSRG recommendations be incorporated into the new SHMP.
Summary • Will adequate funding be available to monitor and evaluate incorporated HSRG recommendations: • Determine proper size of hatchery program for segregate and integrated programs • Wild fish are protected for the long term • Segregated program impacts • Continued hatchery/wild interactions • Integrated program impacts • Monitor the changing fisheries & escapement composition • Continued hatchery/wild interactions due to grater proportion of spawning hatchery fish (up to 33%) • Will tribal and recreational fishers accept changes in their fisheries, due to HSRG?
