Özet

In this study, Black Sea trout (Salmo trutta labrax, Pallas, 1811) and Rainbow trout (Oncorhynchus mykiss, Walbaum 1792) were reared in mono and duo-culture groups. Duo-culture groups were designed to include changing numbers of individuals for each species to assess the effect of dominance. The effect of the culture strategy on growth and survival rates during the feeding transition period was compared. The growth performance of mono and duo-culture groups were found similar whereas the survival rates of the groups differed significantly. The survival rate of the duo-culture group with the 75/25 stock density for two species was found lower when compared with monoculture groups and groups of 50/50 stock density. The feed conversion ratio (FCR) for all groups was similar.
