Abstract

Some growth properties of the brown trout Salmo trutta macrostigma (Dumeril, 1858) in Tekederesi, which is a branch feeding the Karasu River, were investigated. The age composition of the population varied between I and V. The population was 64.81% female and 35.19% male and the differences between the sexes were statistcally significant (P < 0.05). The mean fork length and mean body weight of the 54 individuals examined were 16.58 cm and 53.15 g, respectively. The differences between the sexes according to age groups for fork length and total weight were not statistically significant (P > 0.05). The specific and relative growth for length and weight were maximum at the second age. The length-weight relationship of the population was calculated by the least squares method and the logarithmic equation was found to be Log W = -1.4684 + 2.590 Log FL (fork length). The mean condition factor of the population was 1.052, and the differences between the sexes were not statistcally significant (P > 0.05).
