Operational Plan for the Restoration of Diadromous Fishes to the ...

� Strategy- Use stocking data and trap data to determine
survival and homing of fish stocked above Weldon. Shift
management resources away form areas that have limiting
factors that likely prevent recovery and aggressively manage
areas that are promising for recovery.
• Measure 4f: Return rate and number of rejuvenated kelts
� Strategy- Estimate kelt to spawner survival. Use data to
improve population models. Determine if this survival can be
improved. If so, pursue actions to improve if modeling
suggests a worthwhile benefit of the population.
� Strategy- Assess the potential of kelt rejuvenation. Do
experimental work if needed. Use modeling to predict
benefit and help make management decision as to value of
such a program.
Objective 5: Achieve interim juvenile life stage-specific measures to assess progress
towards goal and to inform management at specific shorter time intervals. Achieve
within five years of a sub-drainage achieving 20 % of Objective 1 measures for
hatchery and wild fish combined (Table 1). Applies to both hatchery and wild fish,
but applies to wild fish only to reach Objective 1.
• Measure 3a: On average > = 240 eggs per unit deposition on annual
basis within five years of a sub-drainage achieving 20 % of Objective 1
measures for hatchery and wild fish combined (Table 1).
o Redd counts extrapolated to # eggs
� Strategy- Improve fish passage
� Strategy- stock adults
� Strategy- trap and truck sea-run adults
� Strategy- Increase upstream escapement by decreasing
broodstock take and/or increasing adult returns.
� Strategy- Develop more precise egg deposition rates for
sub-drainages.
• Measure 3b: Use following measures (3c-3e) for hatchery and wild
juveniles. Compare hatchery verses wild survival and/or population
densities and smolt production.
• Measure 3c: > = 90 % density quantile (from cumulative drainage area
quantile regression model) or greater YOY and parr per unit of habitat
within five years of a sub-drainage achieving 20 % of Objective 1
measures for hatchery and wild fish combined (Table 1). Electrofishing
estimate or CPUE equivalent
� Strategy- Stock fry and improve fry stocking methods
� Strategy- Stock eggs and improve egg stocking methods
� Strategy- Stock reaches most likely to yield desired
densities
� Strategy- Increase connectivity
� Strategy- Improve habitat complexity
