摘要:
Relative recoveries of landlocked salmon Salmo salar planted at ages 0+ (fall), I (spring) and I+ (fall) were compared by analysis of variance and a multiple range test. Data were collected from angler catches (1963–69) and from trap net catches (1963–70). Sample sizes were 987 salmon from angling and 1,018 salmon from netting. The analysis of variance revealed a significant difference in recoveries of salmon of different ages at planting, and the Student-Newman-Keuls multiple range test showed that the significant difference was between age 0+ and age I+ salmon. At Schoodic Lake, comparable sport fisheries could be provided by stocking either 1,000 age I+ salmon or 2,800 age 0+ salmon. The smaller salmon would cost only 70% as much as the larger.
