� Strategy- Assess environmental conditions that are<br />

limiting<br />

� Strategy- Use quantile regression model coupled with<br />

development <strong>of</strong> adaptive management criteria based on<br />

quantiles.<br />

• Measure 3d: > = 3 smolts per unit (240 eggs/unit*0.0125 or estimate<br />

from parr quantile regression and typical smolt survival) within five<br />

years <strong>of</strong> a sub-drainage achieving 20 % <strong>of</strong> Objective 1 measures <strong>for</strong><br />

hatchery and wild fish combined (Table 1).<br />

o Smolt trap or o<strong>the</strong>r estimation method<br />

� Strategy- See 3c above…<br />

• Measure 3e: Egg <strong>to</strong> smolt survival <strong>of</strong> > = 1.25% within five years <strong>of</strong> a<br />

sub-drainage achieving 20 % <strong>of</strong> Objective 1 measures <strong>for</strong> hatchery and<br />

wild fish combined (Table 1).<br />

o Analysis <strong>of</strong> data<br />

� Strategy- See 3c above…<br />

� Collect appropriate juvenile abundance data and smolt<br />

data <strong>to</strong> assess. Use un-biased sampling approach.<br />

Objective 6: Increase upstream migra<strong>to</strong>ry survival rate within 15 years <strong>to</strong> allow selfsustaining<br />

levels.<br />

• Measure 6a: Improve upstream fish passage at dams <strong>to</strong> levels needed<br />

<strong>for</strong> self-sustaining population<br />

� Strategy- Estimate required passage efficiencies<br />

� Strategy- Review current in<strong>for</strong>mation and use <strong>to</strong> direct<br />

fur<strong>the</strong>r action under this objective.<br />

� Strategy- Assess fish passage at all dams as needed<br />

within 5 years<br />

� Strategy- Complete improvements based on passage<br />

efficiency and population effect within 10 years.<br />

� Strategy- Target current focus res<strong>to</strong>ration areas.<br />

• Measure 6b: Improve stream connectivity (small dams, culverts etc.) <strong>to</strong><br />

levels needed <strong>to</strong> achieve desired Ne and N.<br />

� Strategy- Assess connectivity limitations within 5 years<br />

� Strategy- Fix connectivity problems based on passage<br />

efficiency and population effect within 10 years<br />

� Strategy- Target current focus res<strong>to</strong>ration areas.<br />

Objective 7: Increase downstream migra<strong>to</strong>ry survival rate within 15 years <strong>to</strong> allow<br />

self-sustaining levels.<br />

• Measure 7a: Improve downstream fish passage at dams <strong>to</strong> levels<br />

needed <strong>for</strong> self-sustaining population<br />

� Strategy- Estimate required passage efficiencies<br />

� Strategy- Review current in<strong>for</strong>mation and use <strong>to</strong> direct<br />

fur<strong>the</strong>r action under this objective.<br />
