The comparison some of growth characteristic in pike (Esox lucius Linnaeus, 1758) from Anzali and Amirkelayeh wetlands

The aim of this study was to estimate growth parameters of pike (Esox lucius) from Anzali and Amirkelayeh wetlands. In total, 272 and 148 specimens from Anzali and Amirkelayeh wetlands, respectively, were caught using fixed gill nets and fyke nets from November 2012 to June 2013. The age ranges were between 1 and 7 years for fish in both wetlands. Approximately, 74.53% of fish consisted of 3 and 4 years old fish. Additionally, Tmax calculated 23.08 and 21.43 for fish of Anzali and Amirkelayeh wetlands, respectively. Total length (TL) and weight (W) of pike ranged (20.4 to 71.3 cm) and (100 to 2635 g) in Anzali wetland and (19.2 to 73.6 cm) and (90 to 3140 g) in Amirkelayeh wetland. The b value of the length-weight relationship for fish of Anzali and Amirkelayeh wetlands ranged 2.782 and 2.856, respectively, indicating negative allometric growth (b
