摘要

本研究旨在揭示加利波利半岛(土耳其爱琴海北部)大西洋鲐鱼(Scomber colias Gmelin, 1789)的年龄和生长情况。于2016年1月至2016年12月期间,每月在商业鱼贩中随机取样大肠弧菌个体。共有348块耳石被成功老化。年龄标本的总长度为16.0 ~ 28.0 cm,总重量为31.72 ~ 222.68 g,平均长度为22.0 cm,总重量为101.23 g。长度-权重关系估计为W = 0.0060TL3.20 (R2 = 0.97)。所有样本的von Bertalanffy生长方程为𝐿∞= 32.0 cm, k = 0.30 year-1,𝑡0 = -1.72 year。生长性能指数( ')为2.49。本研究首次提供了关于该物种生长参数的信息,从而确定了加利波利半岛(土耳其爱琴海北部)的当前状态Scomber colias种群。

Estimation of growth parameters of the Atlantic chub mackerel (Scomber colias Gmelin, 1789) off Gallipoli Peninsula (Northern Aegean Sea, Turkey)
This study was carried out to reveal the age and growth of the atlantic chub mackerel (Scomber colias Gmelin, 1789) in Gallipoli Peninsula (northern Aegean Sea, Turkey). The individuals of sampled S. colias from commercial fishmongers randomly each month were taken during the period January 2016-December 2016. A total of 348 otoliths were aged successfully. The total length and weight of aged specimens ranged from 16.0 to 28.0 cm and from 31.72 to 222.68 g, with a mean of 22.0 cm and 101.23 g, respectively. The length-weight relationship was estimated as W = 0.0060TL3.20 (R2 = 0.97). The von Bertalanffy growth equations were computed to be 𝐿∞ = 32.0 cm, k = 0.30 year-1, 𝑡0 = -1.72 year for all samples. The growth performance index (𝛷′) was found as 2.49. The present study provides the first information on the growth parameters of the species so as to define the current state Scomber colias population for Gallipoli Peninsula (northern Aegean Sea, Turkey).
