摘要

摘要本研究涉及马尔马拉海（土耳其）常见比目鱼Solea Solea（Linneaus，1758）的生长模式、死亡率和繁殖。2017年10月至2018年9月，每月共采样580个鱼类标本。所有采样个体的总长度在11.1至29.5厘米之间，对应的年龄为1至3岁。长度-重量关系表示为W=0.022 TL2.6838，其中斜率表示负异速生长。所有样品的生长参数为L∞=33.7cm，k=0.48，t0=-0.18。一个季节性振荡增长模型显示了振荡的幅度，揭示了一个重要的季节性增长模式。总死亡率、自然死亡率和捕鱼死亡率分别计算为1.42、0.47和1.01。利用率（E=0.68）表明马尔马拉海普通比目鱼的捕捞压力很大。性别比例(♀/♂) 为1.18。雌性的性腺体指数（GSI）显示，观察到两个主要的产卵季节：一个在春季（5月），一个在秋季（9-10月）。雌性和雄性在性成熟开始时的体型估计分别为21.6和18.6厘米。

Growth pattern, mortality and reproductive biology of common sole, Solea solea (Linneaus, 1758), in the Sea of Marmara, Turkey

Abstract The study deals with the growth pattern, mortality, and reproduction of common sole, Solea solea (Linneaus, 1758), from the Sea of Marmara (Turkey). A total of 580 fish specimens were sampled monthly from October 2017 to September 2018. The total length of all sampled individuals ranged from 11.1 to 29.5 cm, corresponding to ages from 1 to 3 years. The length–weight relationship was expressed as W = 0.022 TL2.6838, where the slope indicated negative allometric growth. Growth parameters were L∞ = 33.7 cm, k = 0.48, and t0 = −0.18 for all samples. A seasonally oscillating growth model, indicating the amplitude of oscillations, revealed an important seasonal growth pattern. Total, natural, and fishing mortality rates were calculated as 1.42, 0.47, and 1.01, respectively. The exploitation ratio (E = 0.68) indicates that the fishing pressure on the common sole in the Sea of Marmara was high. The sex ratio (♀/♂) was 1.18. The gonadosomatic index (GSI) for females showed that two main spawning seasons were observed: one in spring (May) and one in autumn (September–October). Sizes at the onset of sexual maturity were estimated for both females and males at 21.6 and 18.6 cm, respectively.
