This study describes a new recreational fishing method focused on marine catfish, Genidens barbus (Endangered-EN), through the adoption of its eggs as a natural bait during its reproductive period in southern Brazilian ecosystems. Male G. barbus perform parental care, collecting eggs released by females after the fertilization process. Owing to this male behavioural pattern during the reproductive period, these individuals are easily caught in recreational fisheries that use eggs of the same species as a natural bait. The current adoption of G. barbus eggs as bait may intensify the fishing pressure on its populations. This article is protected by copyright. All rights reserved.

当有利的繁殖特性变坏时：濒危鱼类 Genidens barbus 的卵作为休闲渔业中的天然诱饵

本研究描述了一种新的休闲捕鱼方法，主要针对海洋鲶鱼 Genidens barbus (Endangered-EN)，通过在巴西南部生态系统的繁殖期采用其卵作为天然诱饵。雄性 G. barbus 执行父母照顾，收集受精过程后雌性释放的卵。由于这种雄性在生殖期间的行为模式，这些个体很容易被使用相同物种的卵作为天然诱饵的休闲渔业捕获。目前采用 G. barbus 卵作为诱饵可能会加剧其种群的捕捞压力。本文受版权保护。版权所有。
