Abstract
Salmo trutta is one of the native fish that is endangered due to the sensitivity to environmental pollutants (entry of various pollutants including domestic, industrial, detergents, petroleum, etc.) of its generation. This study was carried out on 140 fresh salmon trout (Salmo trutta) fish from the mountainous region of Lar Lake in 2008 and 2009. The study their demographic structure. Based on Kruskal-Wallis non-parametric test, the statistical difference in gonadal weight (1.26 ± 0.016), relative weight of gonad (1.21 ± 0.020), Fulton index (1.50 ± 0.017) and Clark index (0.99 ± 0.015) was observed (p <0.05). T-test did not show any statistical difference in indexes such as body weight (153.44 ± 9.60 gr) and fork length (21.72 ± 1.85 cm) in both males and females at different ages (p> 0.05).
