摘要:
Standing crops of juvenile rainbow trout in seven bank crib and six pool digger areas were compared with those in natural overhanging banks and pools. There was no difference in biomass, average weight, or number of trout between altered and natural areas. Trout comprised a significantly greater percentage of the total fish biomass in bank crib sections than pool digger sections. A low ratio (1.1:1) of number of age 0+ to older juvenile trout reflected selectivity of the older trout for the sample sections, since Cayuga Inlet in general had a much higher ratio (4.2:1).
