Temperature Requirements in Atlantic Salmon ( Salmo salar ), Brown Trout ( Salmo trutta ), and Arctic Char ( Salvelinus alpinus ) from Hatching to Initial Feeding Compared with Geographic Distribution
Development time at different temperatures from hatching to 50% feeding was studied in Atlantic salmon (Salmo salar) and brown trout (Salmo trutta) alevins. Live animals were used as food. In both species the development time decreased with increasing temperature, and these relationships were descri...
