The growth characteristics of Perca fluviatilis in Fukang Reservoir,Xinjiang
摘要
Abstract
To evaluate the current status of Perca fluviatilis population in Fukang Reservoir,Xinjiang Uygur Autonomous Region,the age composition and growth characteristics of 201 P.fluviatilis specimens collected in 2021 were studied.The results showed that the age composition of the captured P.fluviatilis ranged from 1+to 7+years old,indicating a isometric pattern.The regression equation for body weight(W)and body length(L)was:W=0.021 9L2.964 8.The body length growth equation was:Lt=71.373 4[1-e-0.103 5(t+0.026 9)],where the body length growth coefficient(k)was 0.103 5,the estimated asymptotic length(L∞)was 71.37 cm,and the theoreti-cal age at growth(t0)was-0.026 9 years old.The body weight growth equation was:Wt=6 852.208[1-e-0.103 5(t+0.026 4)]2.964 8,where the body weight growth coefficient(k)was 0.103 5,the estimated asymptotic body weight(W∞)was 6 852.2 g,the theoretical age at growth(t0)was-0.026 4 years old,and the inflection age of body weight growth occurred at 10.5 years of age.The results showed that the current exploitation intensity of P.fluviatilis stock was relatively low.Therefore,it is recommended to optimize fishing gear and methods,initiate harvesting from age 3+,and increase fishing intensity appropriately to better manage the resource.关键词
