Abstract

Daily growth rates and pelagic larval duration were investigated in the common two-banded seabream (Diplodus vulgaris). Fish were sampled using a beach seine from the shallow waters of Gökçeada Island, Turkey, between June 2013 and June 2014. The minimum and maximum daily age estimates were 41 and 339 d, respectively. The mean daily growth rate of young-of-the-year D. vulgaris was 0.330 mm·d–1. Our results showed that D. vulgaris exhibits a Type Ia settlement-mark with a pelagic larval duration of 29 d. The hatching period occurred from November to April. The maximum hatching frequencies were observed in winter, when the water temperature was relatively low. The natural logarithm of young-of-the-year abundance data was plotted against age, and the instant mortality coefficients were estimated. The relationships between total length and otolith morphometric measurements (otolith length [OL], width [OW], and radius [OR]) were defined by linear equations. Furthermore, it was observed that this ratio exhibited a linear relationship with OL, OW, and OR and total length and daily age.

常见的双带鲷Diplodus vulgaris（鲈形目：雀鲷科）的早期生活特征，栖息在土耳其Gökçeada岛的浅水区

研究了常见的双带鲷（Diplodus vulgaris）的日生长率和浮游幼体的持续时间。2013年6月至2014年6月，使用海滩围网从土耳其哥克塞达岛浅水区对鱼类进行了采样。每日最低和最高年龄估计值分别为41天和339天。当年小球藻的平均日生长速率为0.330 mm·D–1。我们的结果表明，D.vulgaris表现出Ia型定居标记，远洋幼虫持续时间为29d。孵化期为11月至4月。最大孵化频率出现在冬季，当时水温相对较低。根据年龄绘制了当年年轻人丰度数据的自然对数，并估计了瞬时死亡率系数。总长度和耳石形态测量值（耳石长度[OL]、宽度[OW]和半径[OR]）之间的关系由线性方程定义。此外，观察到该比率与OL、OW和OR以及总长度和日龄呈线性关系。

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.
