围网网具性能研究进展

很多国家与地区的围网渔业在近海和远洋都有着较快速的发展。随着渔业管理日趋严格、能源成本的提升以及科学技术的发展,生态保护和能源节约日益受到关注。围网网具的研究也步入到性能优化的阶段。本文对国内外关于围网网具性能研究的文献进行梳理,概括了利用海上实测、模型试验和数值模拟方法研究围网作业性能的热点问题(沉降性能,网具受力,网具形状等),为围网的网具结构设计、渔法改进和围网性能优化提供基础依据。

Gear performance of the purse seine: A review

Purse seine fishing has developed rapidly in inshore and offshore fisheries in many parts of the world. The ecological balance and energy crisis are receiving increasing attention, together with the strict management of fisheries, growing energy consumption, and scientific and technological developments. Therefore, in this context, the optimal design of the purse seine is a very important issue for the industry. This study summarizes the study approaches used to address the difficult questions about the gear performance of the purse seine (sinking per-formance, tension force, and geometry), based predominantly on sea trials, model experiments, and dynamic simulations. An optimization strategy for the purse seine is proposed to improve the configuration of the gear and the operational technology, and to optimize the performance of the purse seine gear.
