The effect of salinity on spotting features of Salmo trutta abanticus, S. trutta fario and S. trutta labrax of cultured brown trout

Morphological differences in the skin of marble trout Salmo marmoratus and of brown trout Salmo trutta.

Despite being genetically very closely related, the marble trout Salmo marmoratus and the brown trout Salmo trutta exhibit marked phenotypic differences, particularly with regard to skin pigmentation. Histological analysis of skin from the head and gill cover of differently aged individuals of the two species was carried out in order to characterize differences in skin structure. The basic stru...

Effect of Duo-Culture on Growth Performance of Brook Trout (Salvelinus fontinalis Mitchill, 1814) and Black Sea Trout (Salmo trutta labrax Pallas, 1811) in Tank Reared Condition

The objectives of the present study were to compare growth performance and feed conversion ratios of brook trout (Salvelinus fontinalis) and Black Sea trout (Salmo trutta labrax) in monoculture and duo-culture tank reared conditions. The fish were about 9-month-old hatchery reared brook trout and Black Sea trout with initial weights of 24.18±0.64 (n=60) and 23.87±1.11 (n=60) g, respectively. Fi...

Comparison of Hatching Performances and Yolk Sac Absorptions of Black Sea Trout (Salmo trutta labrax Pallas, 1811), Brook Trout (Salvelinus fontinalis Mitchill, 1814) and Their Hybrid

The aims of this study were to determine hatching performance, body and yolk weight at hatching, the growth rate during the yolk absorption and yolk conversion efficiency of Black Sea trout, brook trout and their hybrid larvae, and to compare the relationships between length, total wet weight, dry yolk body weights of alevins and degree-days. The Black Sea trout egg has shorter incubation durat...
