Abstract

Length–weight relations of 14 fish species caught by small-scale fishery from the Chalakudy River of the Western Ghats biodiversity hotspot, India were analyzed from April 2018 to March 2019. The following species were studied: Amblypharyngodon microlepis (Bleeker, 1853); Dawkinsia filamentosa (Valenciennes, 1844); Puntius mahecola (Valenciennes, 1844); Osteobrama bakeri (Day, 1873); Labeo dussumieri (Valenciennes, 1842); Channa marulius (Hamilton, 1822); Channa striata (Bloch, 1793); Horabagrus brachysoma (Günther, 1864); Mystus armatus (Day, 1865); Pangasianodon hypophthalmus (Sauvage, 1878); Heteropneustes fossilis (Bloch, 1794); Etroplus suratensis (Bloch, 1790); Megalops cyprinoides (Broussonet, 1782); Parambassis thomassi (Day, 1870). The main fishing gear that was used in the data collection were gill nets, seine nets, and cast nets. The b values in the LWRs ranged from 2.649 (L. dussumieri) to 3.023 (P. hypophthalmus). This study reports the first LWR reference for five species and new maximum total lengths for five species. The results provide baseline information for the sustainable management and conservation of the studied species.

印度西高止山脉Chalakudy河14种放线鱼的长重关系

分析了2018年4月至2019年3月印度西高止山脉生物多样性热点地区Chalakudy河小规模渔业捕获的14种鱼类的长度-重量关系。研究了以下种类:Amblypharyngodon microlepis (Bleeker, 1853);丝状Dawkinsia filamentosa (valcienne, 1844);Puntius mahecola (valcienne, 1844);bakeri骨瘤(Day, 1873);Labeo dussumieri (valcienne, 1842);Channa marulius (Hamilton, 1822);紫纹草(Bloch, 1793);Horabagrus brachysoma (g nther, 1864);Mystus armatus (Day, 1865);Pangasianodon hypoophthalmus (Sauvage, 1878);Heteropneustes化石(Bloch, 1794);白鳗(Bloch, 1790);巨型鲤科植物(Broussonet, 1782);Parambassis thomassi (Day, 1870)。数据收集中使用的主要渔具是刺网、围网和鱼网。lws的b值在2.649 ~ 3.023之间。本文报道了5个物种的首个LWR参考文献和5个物种新的最大总长度。研究结果为研究物种的可持续管理和保护提供了基础信息。
