Abstract :In this study, data on the incubation of eggs, survival rates and development of brook trout insert ignore into journalissuearticles values(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 ºC, 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 insert ignore into journalissuearticles values(r = 0.945, P < 0.01);.
