本文通过对 2 0 0 0年海上生产调查试验的总结分析 ,初步研究了西南大西洋鱿钓作业中有关钓钩和钓线使用的生产技术问题。结果表明 :①不同颜色的钓钩的渔获效果有差异 ,以草绿色钓钩的渔获效果最好 ;②应将钓线保持在深海声波扩散层 (DSL)的上方水层进行钓捕 ;③生产中应根据渔获物个体大小的变化对钓钩的规格、单根钓线的钓钩数量和钓线的粗度进行调整。渔汛初期可使用 =1.0mm的钓钩 ,单根钓线装 2 5～30只钓钩 ,钓线选用 5 0 - 6 0号 ;渔汛末则可选用 =1.17- 1.30mm的钓钩 ,单根钓线装 15～ 2 0只钓钩 ,钓线选用 80 - 90号
Based on the summary of the survey of offshore production in 2000, this paper studies the production technology of fishing hooks and fishing lines used in squid fishing operations in the Southwest Atlantic. The results showed as follows: ① The fishing effects of different color fishing hooks are different, and the fishing with green grass hooks is the best; ② The fishing line should be kept in the upper water layer of deep-sea acoustic wave diffusion layer (DSL) for fishing; ③ The production Should be based on changes in the size of individual catches fishing hook specifications, the number of single fishing line hooks and fishing lines to adjust the roughness. In the early stage of the fishing season, 钓 = 1.0mm hooks, 25 to 30 hooks for a single fishing line, and 50 to 60 lines for fishing line can be used. At the end of the fishing season, hooks of = 1.17-1.30mm can be used, 15 ~ 20 fishing hooks, fishing lines use 80 - 90
