摘要: Abstract The changes in some of the biological traits mature females critically endangered Caspian Brown Trout, Salmo trutta caspius Dorofeeva, 1967, during recent decades were analysed. results demonstrated that mean length has significantly (p 0.05) difference between relative fecundity 1947 (1451.4 per kg body weight) and 1973 (1372.6 weight), a significant (p<0.05) reduction been observed since 1986 (1199.8 weight). possible reasons for these are discussed. Based on this study, exploitation sale must be controlled, efforts should c...
