Population and maturity characteristics of Commerson’s anchovy (Stolephorus commersonnii) from the south-west coast of India have been presented here to elaborate upon the fishery of the species in the region. The present study on Commerson’s anchovy formed the first of its kind from the Indian waters and showed that the lifespan of the species is 3.06 years. The results also revealed that Commerson’s anchovy attains the length of 10.2, 13.5 and 14.7 cm at the end of 1^st, 2^nd and 3^rd year of its life. The recruitment pattern of Commerson’s anchovy has two peaks - a minor one from February to March and a major one from June to July. The length-frequency analysis for the probability of capturing the species showed that the length at the first capture was 8.2 cm, indicating that the fish mostly being commercially exploited after they reach the first maturity i.e. the length of 7.1 cm. Total mortality, natural mortality and fishing mortality of the species were calculated as 2.78, 2.18 and 0.64 Y^-1, respectively. Virtual population analysis (VPA) indicated that the number of natural mortality of the species is much larger than the commercial utilization, indicating the low exploitation of the species from the southwest coast of India.

印度西南沿海Commerson cho鱼（Stolephorus commersonniiLacepède，1803年）的种群增长和成熟特征

这里介绍了来自印度西南沿海的Commerson cho鱼（Stolephorus commersonnii）的种群和成熟特征，以详细说明该地区该物种的渔业。目前对Commerson cho鱼的研究是从印度海域形成的，这是该种类中的第一个，表明该物种的寿命为3.06年。该结果还表明，Commerson的凤尾鱼届10.2，13.5和14.7厘米长度为1的端部^ST，2^次和3^次生命的一年。Commerson的cho鱼的招聘模式有两个高峰-从2月至3月为次要高峰，从6月至7月为主要高峰。用于捕获物质表明，在第一个捕获的长度为8.2厘米，表明鱼大多在它们到达第一成熟后正在商业开发的概率的长度-频率分析，即7.1厘米的长度。该物种的总死亡率，自然死亡率和捕捞死亡率分别计算为2.78、2.18和0.64 Y ^-1。虚拟种群分析（VPA）表明，该物种的自然死亡数量远大于商业利用数量，表明该物种在印度西南海岸的开发利用程度较低。
