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.
