Two strategies for genetic monitoring of hatchery supplementation • Gene frequency monitoring design: • Change in allele frequencies through time among hatchery, natural, and wild populations • Reproductive success design: • Pedigrees in natural populations and hatchery broodstocks
Little Sheep Creek Snake River Basin geneticmonitoring study area
Little Sheep Creek steelhead • Mitigation/supplementation program • In operation for ~4 generations • Local broodstock • Sustained incorporation of wild spawners • Accelerated rearing schedule

Correlates of reproductive success • mate choice/competition • spawn time/location • sperm competition/fecundity • gamete/offspring viability • egg-parr, parr-smolt, smolt-adult • phenotypic traits
Estimation of selection gradients Model is a modification of Smouse, Meagher and Kobak (J Evol Biol 12:1069-1077); Morgan and Conner (Evolution 55:272-281) relative fitness of female j relationship between fitness and traits likelihood of observing offspring i likelihood of observing offspring sample
Steelhead selection gradients Larger females are more fit… Length …but not so larger males Length
Early returning fish are more fit Run timing
Pedigree studies at NWFSC • Little Sheep Creek steelhead • Lostine River Chinook • Catherine Creek Chinook • Upper Grande Ronde Chinook • Wenatchee River Chinook • Minter Creek coho
Reproductive success in NE Oregon Chinook captive broodstock programs Preliminary results show progeny of captive fish similar to wild in Lostine River and Catherine Creek
Reproductive success studies • Relate reproductive success to specific quantitative genetic traits and rearing regimes in both hatchery and wild • Pedigrees provide detailed characterization of micro-evolutionary processes
Conventional gene frequency monitoring studies • Allele frequency changes through time among hatchery, natural, and wild populations • Infer short-term reproductive success superimposed on long-term evolutionary divergence

Traditional genetic monitoring Geographic, temporal, and programmatic scale not possible with pedigree studies
Direct study of adaptation and domestication • Quantitative genetics via natural pedigrees • Microsatellite markers linked to functional genes • Resident/anadromous, hatchery/wild, resistant/susceptible Structural gene Microsatellite marker Fish chromosome
Future role of genetic M&E • Artificial propagation with reform remains central to recovery planning • Current genetic methods provide powerful tools for real-time M&E of hatchery reform
