摘要

Togok是一种渔具,其形状为圆锥形网体,其手臂在两根杆子上,捕获成功取决于水流。Togok渔具用于捕获Rebon虾(Acetes japonicas),但在操作过程中,许多捕获物被发现是副捕获物。大量的副渔获物会对可持续捕捞渔业产生影响,减少副渔获物的努力之一是使用BRD(副渔获物减少装置),BRD已在拖网渔具上广泛使用,但在togok渔具上却从未使用过。本次研究的目的是了解安装绳索BRD的togok渔具的主要渔获物和副渔获物的渔获量减少情况,并了解虾和鱼类的渔获量减少情况。本研究采用实验捕鱼方式,即与当地渔民进行为期20天的直接捕鱼作业。使用BRD型绳的主要捕获量减少了8.4%,副捕获量减少了11.8%,丢弃量减少了17.1%,虾类捕获量减少了8.4% ~ 13.5%,鱼类捕获量减少了10.9% ~ 22.6%。

Pengurangan Hasil Tangkapan Pada Alat Tangkap Togok dengan Menggunakan BRD (Bycatch Reduction Device) Tipe Rope BRD di Kuala Tungkal, Provinsi Jambi
Togok is a fishing gear in the form of a conical net body whose arms are on two poles and the success of catching it relies on currents, togok fishing gear is used to catch Rebon shrimp (Acetes japonicas) but in its operation, many catches are found bycatch. The high bycatch will have an impact on capture sustainable fisheries, one of the efforts to reduce bycatch is by using BRD (Bycatch Reduction Devices), the use of BRD has been widely carried out on trawl fishing gear but on togok fishing gear, it has never been done. This study aimed for knowing the reduction in catches of main catch, bycatch, and discard the togok fishing gear that has been installed with rope BRD and knows the reduction in catches of shrimp and fish species. This study uses experimental fishing, namely by carrying out direct fishing operations with local fishermen for 20 days of catch. The reduction of togok catch using BRD type rope BRD in the main catch is 8.4%, in bycatch is 11.8% and discard is 17, 1% and the reduction in catch of shrimp species ranged from 8,4% - 13,5% and reduction in catch of fish species ranged from 10,9% - 22,6%.
