Özet

In this study, data on the incubation of eggs, survival rates and development of brook trout (Salvelinus fontinalis, Mitchill 1814) larvae and alevins were evaluated. Durations of eyeing, hatching and swim-up were 245, 415 and 675 degree-days at a temperature range of 4-12 degreesC, while survival rates from fertilisation to hatching and from fertilisation to swim-up stage were 56.5% +/- 24.28 and 52.0% +/- 23.67, respectively. Alevin weight exhibited a positive relationship with egg size (r 0,945, P < 0.01).
