Growth Dynamics of Three Trout Species (Oncorhynchus mykiss, Salvelinus fontinalis and Salvelinus alpinus), in Accordance with Environmental Parameters.

In the context of increase the fish farms productivity and diversification of aquaculture products, have been evaluated the growth dynamics of three species of trout: rainbow trout (Oncorhynchus mykiss), brook trout (Salvelinus fontinalis) and arctic charr (Salvelinus alpinus). All three species of trout were grown in Trecătoarea Ursului trout farm, Braşov County and have benefited from the same environmental parameters and the same feeding conditions. The growth dynamics of rainbow trout was significantly higher, compared to the other two species. This is the result of domestication and improvement of rainbow trout, as well as its genetic characters. The lower growth dynamics of brook trout and arctic charr increase the production price, this aspect having directly implications on the selling price. [ABSTRACT FROM AUTHOR]
