چکیده
|
The length- length (llrs), length-weight (lwr) relationships and relative condition factor (kn) of 505 specimens of pike, (esox lucius linnaeus, 1798) from anzali wetland, southwest of the caspian sea, were studied from april 2012 through march 2013. the length-length relationships among total length (tl), fork length (fl) and standard length (sl) for pike were found to be highly significant (r2 > 0.986, p < 0.001). the values of b in length-weight relationship in males (3.1495), females (3.1843) and for all specimens (3.2137) indicated isometric growth. mean relative condition factor for male, female and all specimens were 1.003, 1.004 and 1.008 respectively. the result of lwr could be used for fishery managers to approve appropriate regulations for sustainable fishery management. few studies have been conducted on these parameters of pike and this is the first report on llrs, lwr and kn of pike from iranian waters.
