Abstract |
Effects of length and condition factor on emigration rates of hatchery-reared smolts of winter steelhead (Oncorhynchus mykiss) stocked 4.7 km upstream of a permanent fish trap were examined. For three releases, an average of 19.8% of fish did not emigrate past the trap. Fish with fork lengths of 190 mm or more and condition factors (K = 105 [weight, g]/[length, mm]3) of 0.90–0.99 generally migrated at higher rates than other fish. |
