摘要

本文报道了尼泊尔赤桑河奥利拉隆礁资料的长度-重量关系。研究对2019年4月至2019年7月收集的30条鱼进行了研究。体重0.8 ~ 5.2 g，体长6.1 ~ 13.4 cm。采用回归分析对数据进行分析。发现长权关系的生长性能非常显著(r=0.936)。发现鱼呈等长生长模式，指数值(b)等于2.5115。

Length-Weight Relationship of Longtail Hillstream catfish Olyra longicaudata (McClelland, 1842)

The present study reports the length weight relationshipof Olyralongicaudata from Chisang River, Nepal. Study was carried out in 30 fishes collected from April 2019 to Jul 2019. The body weight ranged from 0.8 to 5.2 g and total length from 6.1 to 13.4 cm. Regression analysis was done to analyzed the data. The growth performance of length-weight relationship is found to be highly significant (r=0.936). The fish was found to show isometric growth pattern with exponential value (b) equal to 2.5115.
