| 摘 要： | 试验重点在于比较菱形网目与方形网目的鱼虾分隔效果。试验分别采用菱形100mm、菱形120mm、方形100mm和方形120mm四种分隔网片方案,试验证明。菱形120mm分隔网片分隔效果最好,其分隔率为59-69％,两种方形网目的分隔效果则不甚理想。本文同时对桁拖网渔具结构提出意见,并且建议对桁拖网也要实行禁渔期政策。

| Abstract: | This experiment is designed to compare the separation rate between the diamond - mesh and square - mesh separation netting panels. Four different types of separating netting, 100mm, 120mm diamond mesh and 100mm , 120mm square mesh netting, were respectively compared in the experiment. The result indicated that the separation rate of 120mm diamond separating netting was the highest, about 59% - 69%; while the separation rates of the square separating netting were not satisfactory. We suggest that the closure of fishing season for shrimp beam trawling should be taken. |
