Length weight relationship of brown trout Salmo trutta L inhabiting Kan stream Coruh Basin north eastern Turkey

Length-weight and length-length, fork (FL), standard (SL) and total (TL) lengths, relationships were derived for brown trout, Salmo trutta L., inhabiting Kan Stream, Çoruh Basin, eastern Turkey. Sampling was done between January–December of 2001 using electronic fishing gear. The relationships between lengths were all significantly linear (p<0.01), the b value in the length-weight relationship for males and females did not deviate from 3, and this value was significantly lower than 3 in the winter (p<0.01), when the temporal changes were taken into account, indicating that only the sampling time affected the growth pattern of Salmo trutta. Growth was isometric in the spring, summer and fall, but it was negative and allometric in the winter.
