Abstract

The population structure of endemic species arabian goby Сryptocentroides arabicus in Wadi Al‑Bahayes (Oman) (23°40′47″ N; 58°11′36″ E) was investigated using 259 fish sampled in August 2020 and August 2021. In this study, the growth and reproductive traits of C. arabicus were investigated. The length-weight relationship and Von Bertalanffy growth equation were as follows: W = 0.0271L^2.3342, R = 0.8731, Lt = 20.14 (1 – e^{–0.1984(t – 0.053)}). Spawning occurred between March and June. The average fecundity per individual was determined to be 1760 ± 186.5 number/(ind./year). According to the results, the species lives in a wide area in its habitat, although it shows negative allometric growth. Since the other species in the environment, introduce Poecilia latipinna and endemic-predator Aphaniops stoliczkanus, may face the negative effects, the habitat and itself must be protected.

阿曼 Wadi Al-Bahayes 的阿拉伯隐翅鱼（翼手目，戈壁鱼科）的生物学特征：阿拉伯鰕虎鱼的种群结构

摘要利用2020年8月和2021年8月采样的259尾鱼，研究了阿曼Wadi Al-Bahayes（北纬23°40′47″；东经58°11′36″）特有物种阿拉伯鰕虎鱼的种群结构。本研究调查了阿拉伯鲑的生长和繁殖特征。长度-重量关系和冯-贝塔朗菲生长方程如下：W = 0.0271L2.3342，R = 0.8731，Lt = 20.14 (1 - e-0.1984(t - 0.053))。产卵期为 3 月至 6 月。每个个体的平均繁殖力为 1760 ± 186.5 条/（条/年）。结果表明，虽然该物种呈现负异速增长，但其栖息地的生活区域很广。由于环境中的其他物种，如引进的 Poecilia latipinna 和当地特有的食肉动物 Aphaniops stoliczkanus，可能会面临负面影响，因此必须保护栖息地和栖息地本身。
