Abstract

Abstract This paper is the first report on the occurrence of Atherina boyeri in this region. A total of 103 individuals of A. boyeri were caught with fyke-nets (mesh size: 5 mm, polyamide) in May and June 2022. The length and weight of the sampled fish ranged from 6.52 to 8.57 cm and 1.44 to 3.46 g, respectively. The exponent b of length/weight ratio was calculated as 3.091 indicating that species presented an isometric growth. The mean value of the relative condition factor Kn was calculated as 1.106 ± 0.011. In conclusion, this study provides the first and valuable information about the spatial distribution of A. boyeri and the biodiversity of the new habitat of Reyhanlı Dam Lake. Within the scope of the traceability of a newly formed ecosystem, it would be beneficial to more extensively investigate this species in terms of the food web, population dynamics, etc. Therefore, more studies should be carried out to determine the aquatic biodiversity and population dynamics of the fishery resources in the lake. The results of this study should be considered by local fishery management authorities and decision-makers to ensure the sustainability of fishery resources and to implement appropriate fishery management approaches.

首次记录具有重要经济意义的大型沙冶炼厂(Atherina boyeri Risso, 1810，双鱼座:砂冶炼厂科)的生物学参数

摘要:本文首次报道了该地区发生的波叶红丽娜(Atherina boyeri)。2022年5月和6月，用网眼(网眼尺寸:5 mm，聚酰胺)共捕获波耶利沙鼠103只。取样鱼的长度和重量分别为6.52 ~ 8.57 cm和1.44 ~ 3.46 g。长重比指数b为3.091，表明物种呈等长生长。相对条件因子Kn的平均值为1.106±0.011。结果表明，本研究首次揭示了雷汉勒尔湖新生境白杨的空间分布和生物多样性特征。在新形成的生态系统的可追溯性范围内，从食物网、种群动态等方面对该物种进行更广泛的研究将是有益的。因此，需要开展更多的研究，以确定湖泊渔业资源的水生生物多样性和种群动态。地方渔业管理当局和决策者应考虑这项研究的结果，以确保渔业资源的可持续性，并执行适当的渔业管理办法。
