The length-weight relationship was estimated for four live bait fishes i.e, Spratelloides delicatulus, Doboatherina duodecimalis, Pempheris adusta, and Ostorhinchus apogonoides obtained from Agatti island of Lakshadweep, India. Fishes were collected using a lift net with a mesh size ranging from 25 mm to 30 mm, operating at the depth of 9–18 m in the nearshore lagoon waters of Agatti island from March 2020 to April 2021. The LWR parameters; ‘a’ and ‘b’ were found to range from 0.0043 to 0.0087 and from 3.117 to 3.336 respectively with a high correlation coefficient (r²). The study would allow for the conversion of length into weight and vice versa in fish stock assessment models as well as favours the estimation of biomass of these species.

印度阿加蒂岛 (Lakshadweep) 近岸泻湖捕获的土著活饵鱼的长重关系

估计从印度拉克沙德维普的阿加蒂岛获得的四种活饵鱼的长度-重量关系，即Spratelloides delicatulus、Doboatherina duodecimalis、Pempheris adusta和Ostorhinchus apogonoides 。2020 年 3 月至 2021 年 4 月，在阿加蒂岛近岸泻湖水域的 9-18 m 深度作业，使用网眼尺寸为 25 mm 至 30 mm 的提升网收集鱼类。LWR 参数；'a' 和 'b' 分别在 0.0043 到 0.0087 和 3.117 到 3.336 之间，具有高相关系数 ( r ² )。该研究将允许在鱼类种群评估模型中将长度转换为重量，反之亦然，并有利于估计这些物种的生物量。
