Abstract

Background and Objective: The determination of the exact nature of relationship that exists between length and weight of fishes has been recognized as an important part of fishery biological studies. The present study was undertaken to elucidate the pattern of growth of male and female Liza parsia of Ashtamudi lake. The present study provides baseline information on the length weight relationship of L. parsia from Ashtamudi lake, Kollam. The study was undertaken to elucidate the pattern of growth and general well being of Liza parsia of Ashtamudi lake. Materials and Methods: The study was based on the length and weight data of 417 fishes, of which, 259 females of length range 91 mm to 187 m (20-110 g) and 158 males of length range 92-175 mm (20-90 g). The method suggested by Le Cren was followed to compute the length weight relationship. Results: Relationship between total length and weight of female of L. parsia obtained by logarithmic regression are female: Log Y = -1.406+2.7216 Log L, male: Log Y = -1.373+2.6473 Log L. Conclusion: Study indicates that an allometric pattern of growth was shown by the species and it was found to be higher in female.

喀拉拉邦Ashtamudi湖金斑鲻鱼的长度-重量关系

背景与目的:确定鱼类长度和体重之间存在的关系的确切性质已被认为是渔业生物学研究的重要组成部分。本研究旨在阐明阿什塔穆迪湖雌、雄鲤的生长规律。本研究为Kollam Ashtamudi湖的L. parsia的长重关系提供了基线信息。本研究旨在阐明阿什塔穆迪湖梭子鱼(Liza parsia)的生长模式和总体健康状况。材料与方法:以417条鱼的体长和体重数据为基础，其中雌性91 ~ 187 m (20 ~ 110 g) 259条，雄性92 ~ 175 mm (20 ~ 90 g) 158条，采用Le Cren提出的方法计算体长和体重关系。结果:经对数回归计算得到的雌虫总长度与体重的关系为:雌性:Log Y = -1.406+2.7216 Log L，雄性:Log Y = -1.373+2.6473 Log L。结论:研究表明，该物种的生长表现出异速生长模式，且雌性较高。
