摘要

在巴西南部,人们使用各种渔具捕捞多种鱼类。本研究旨在描述巴西南部南里奥格兰德州北海岸个体渔民使用的一种新技术。在 2019 年 6 月的三天时间里,对使用撒网和 "站立划桨 "板捕捞鲻鱼的三对渔民进行了捕捞作业的直接观察和访谈。对 107 个标本进行了采样,其中 99% 的标本总长度超过了初熟长度。因此无法对总捕获量做出准确估计。此外,这项研究还首次记录了一种新的捕鱼技术,并有可能在该地区推广,它还进一步说明,持续的捕鱼监测对于了解捕鱼动态以及管理捕鱼活动至关重要。

Fishing on boards: a new fishing technique in the south coast of Brazil
In southern Brazil, various fishing gear is used to capture numerous species of fish. The present study aims to describe a new technique used by artisanal fishers on thenorth coast of Rio Grande do Sul, southern Brazil. For three days, in June 2019, direct observations of fishing operations and interviews were carried out with three pairs of fishers who used cast nets and "stand-up paddle" boards, aiming to capture mullet. 107 specimenswere sampled, of which 99% had a total length above the length at first maturation. It was not possible to make an accurate estimate of total catch. In addition, to providing the first record of a new fishing technique, with potential for expansion in the region, this study reinforces that constant fishing monitoring is essential for understanding fishing dynamics, as well as for the management of the activity.
