Abstract

Fisheries management practices require reliable data for the assessment of data poor stocks. This paper reported the first knowledge on length-weight relationship (LWR) and condition factor of Atherina boyeri in Atikhisar Reservoir, Çanakkale, Türkiye. A total of 1103 individuals of which 132 were immature was captured in June 2021. The sex ratio male to female was 1:1.75. The relationship between weight (W) and total length (TL), standard length (SL), and fork length (FL) were estimated as W=9E-06TL2.9212, W=1E-05SL2.9082, and W=9E-06FL2.9495. A. boyeri exhibited a negative allometric growth. The mean of Fulton`s condition factor of A. boyeri population in Atikhisar Reservoir was determined as 0.619±0.061. The mean Fulton`s condition factor for female individuals were higher than the males` condition factor and the difference between sexes was statistically significant. The present study made available valuable information on the data poor stock by providing LWR and condition factor of A. boyeri in Atikhisar Reservoir, a new freshwater system for the very euryhaline amphidromous species. The findings of the present study will substantially contribute to the knowledge of the population dynamics of the commercially important species for fisheries managers and decision-makers to maintain sustainable population levels.

数据贫乏存量的初步认识:土耳其Atikhisar水库新建立的阿特纳波耶里种群的LWR和条件因子

渔业管理做法需要可靠的数据来评估数据贫乏的种群。本文首次报道了Çanakkale, rkiye的Atikhisar水库中叶红叶红的长度-权重关系(LWR)和条件因子。2021年6月，共捕获了1103只，其中132只未成熟。男女性别比为1:1.75。体重(W)与总长度(TL)、标准长度(SL)、叉长(FL)的关系分别为W=9E-06TL2.9212、W=1E-05SL2.9082、W=9E-06FL2.9495。波叶菊呈负异速生长。结果表明，水库博耶利种群富尔顿条件因子均值为0.619±0.061。女性个体的富尔顿状况因子均值高于男性个体，性别差异有统计学意义。本研究通过提供极广盐性两性物种的新淡水系统Atikhisar水库的波叶刺青的LWR和条件因子，为数据储量不足提供了有价值的资料。本研究的结果将大大有助于渔业管理人员和决策者了解商业上重要物种的种群动态，以维持可持续的种群水平。

期刊介绍： Turkish Journal of Fisheries and Aquatic Sciences" (TrJFAS) is a refereed academic journal has been published by Central Fisheries Research Institute of Turkey and Japan International Cooperation Agency (JICA), and published in English. It aims to address research and needs of all working and studying within the many varied areas of fisheries and aquatic sciences. The Journal publishes English language original research papers, critical review articles, short communications and technical notes on applied or scientific research relevant to freshwater, brackish and marine environments. TrJFAS was published biannually (April & November) between 2001 and 2009. A great number of manuscripts have been submitted to the journal for review from acceptance of the SCI index. Thereby, the journal has been published quarterly (March, June, September and December) from 2010 to 2017. The journal will be published monthly in 2018.
