Abstract

The aim of this study was to provide a first approximation of the growth, reproduction, and length–weight relationships of Symphodus ocellatus in the southeastern Black Sea, Turkey. A total of 320 specimens (273 males, 47 females) were collected between June 2015 and May 2016, and their biological parameters were estimated for each sex and both sexes combined. Total length ranged from 6.90 to 13.70 cm and the parameters (a, b) in the power length–weight relationships were a = 0.065 and b = 2.38 for males and a = 0.102 and b = 2.20 for females. Age was successfully estimated by commonly accepted procedures for otolith analysis. The von Bertalanffy growth parameters from the otolith age estimation were L∞ = 12.66 cm, k = 0.764, and t0 = –1.151 (0–3 years) for males, and L∞ = 14.15 cm, k = 0.764, and t0 = –0.188 (1–3 years) for females. The monthly gonadosomatic index values reflected a spawning period between April and July, with a spawning peak in May–June. The present study provides the first estimate of the growth and reproduction of S. ocellatus in the southeastern Black Sea of Turkey and compares the results with those from other areas.

在黑海东南部，林奈(Linnaeus, 1758)(双鱼座:唇形鱼科)的生长和产卵期的初步近似

本研究的目的是提供生长，繁殖和长-重关系的第一个近似的Symphodus ocellatus在黑海东南部，土耳其。2015年6月至2016年5月共采集标本320只(雄性273只，雌性47只)，并对其雌雄及两性综合生物学参数进行估算。总长度范围为6.90 ~ 13.70 cm，雄虫的幂长-重关系参数(a、b)分别为a = 0.065和b = 2.38，雌虫为a = 0.102和b = 2.20。通过耳石分析的普遍接受的程序成功地估计了年龄。由耳石年龄估算得到的von Bertalanffy生长参数为:雄性为L∞= 12.66 cm, k = 0.764, t0 = -1.151(0 ~ 3岁);雌性为L∞= 14.15 cm, k = 0.764, t0 = -0.188(1 ~ 3岁)。月促性腺指数值反映产卵期为4 - 7月，产卵高峰在5 - 6月。本研究首次估计了土耳其黑海东南部的S. ocellatus的生长和繁殖情况，并将结果与其他地区的结果进行了比较。

期刊介绍： A bilingual open-access publication, Ciencias Marinas (CM) is an international peer-reviewed journal that contains original research findings in all areas of marine science. It is published quarterly by the Autonomous University of Baja California, Mexico, and all its contents are publicly available on our journal website. Though a limited number of copies are still printed, the journal is mainly distributed in its electronic format. CM was conceived in 1973 as part of an academic project aimed to entice local researchers to publicly disclose their findings by adopting the culture of peer-review publishing. This academic project evolved into an international journal after accepting papers from researchers in the United States and, eventually, other parts of the world. Because of the diversity in authorship, CM issues were initially published in either Spanish or English, and occasionally in both languages. It was not until 1984 when CM included both language versions of all its contents, and it then became the fully bilingual journal it still is today. At CM we believe our inclusive format allows us not only to address a wider range of submissions from international authors but also to make published findings available to a wider international audience. So whether you are looking for information on the redfish in Icelandic waters or the physical and biological properties of the Gulf of California, feel free to peruse CM contents. You may find them to provide source material for your research.
