摘要

刺网是海洋和内陆水域最常用的渔具之一。刺网经常使用不同颜色的细丝网。然而,刺网颜色对捕捞效率的影响对大多数渔业来说尚不清楚。因此,在本研究中,我们调查了刺网颜色对印度Vembanad湖珠斑鱼(Etroplus suratensis)捕捞效率的影响。刺网测试的颜色有透明、绿色和蓝色。结果表明,在该渔场中,三种颜色刺网的捕捞效率差异显著。与透明刺网和蓝色刺网相比,绿色刺网对珍珠斑的捕获效率最高。具体来说,与透明刺网相比,绿色刺网的效率平均估计高出74%。与蓝色刺网相比,绿色刺网的捕获效率估计高出81%。这些结果表明刺网颜色是影响该渔具捕捞效率的重要因素。

Gillnet colour affects catch efficiency in pearlspot (Etroplus suratensis) tropical estuary fishery
Gillnets are one of the most commonly used fishing gears in both marine and inland waters. Different colour filament nettings are often used in gillnets. However, the effect of gillnet colour on catch efficiency is unclear for most fisheries. Therefore, in this study we investigated the effect of gillnet colour on the catch efficiency in pearlspot (Etroplus suratensis) fishery in Vembanad lake, India. Gillnet colours tested were transparent, green and blue. Results showed that in this fishery, the catch efficiency of gillnets of the three colours tested differed significantly. The highest catch efficiency of pearlspot was shown by green gillnets compared to transparent or blue netting. Specifically, green gillnets on average were estimated to be 74% more efficient compared to transparent gillnets. For the green compared to the blue gillnets, the catch efficiency was estimated to be higher by 81%. These results demonstrate that gillnet colour can be an important factor significantly affecting the catch efficiency of this fishing gear.
