GROWTH RATE OF BREAM [ABRAMIS BRAMA (L.)] IN LAKE DˇBIE.
Włodzimierz Załachowski, Kazimierz Więski
ABSTRACT
Length and weight growth rates of 206 bream individuals caught in 1992 and 1995 were back-calculated. Different types (non-linear vs. linear) of a relationship between the scale caudal radius and body length were revealed to prevail in the two years. The 1992 bream grew very rapidly during the first four years of life, the growth rate slowing down later on. On the other hand, the bream growth in 1995 was more uniform over time. No sex- or age-dependent differences in growth rate were found. The Lake Dąbie bream population belongs to the fast growing populations of the species.
Key words: bream, rate of growth, length-weight relationship.
