| 摘 要： | 为了克服养殖池传统拉网作业中存在的"缺氧"、"闷网"等弊端,提高拉网成活率,降低损失,笔者单位经过多年的研究,总结出一种新型的小型池塘拉网方法。该法将整个捕捞作业分为搭建临时网箱和单边环塘拉网两部分。拉网共需4~5人,放缓拉网速度,将养殖动物以边拉边赶的方式驱赶至网箱内暂养,然后在网箱内挑选渔获物。试验表明,本法适用于3 000~10 000 m2的小型池塘拉网作业,具有成本低、效率高、伤害小等优点,适用于亲本的无伤害捕捞。

| Abstract: | In order to overcome the hypoxia and stuffy in the nets in the traditional fishing method, to improve the survival rate, and to reduce losse, we invented a new kind of pond fishing method.The entire fishing operation was divided into two parts, including building temporary cages and one-side surrounding dragnet fishing.The entire fishing operation needed 4-5 people, with slower moving of workers.Breeding animals were driven to keep inside the cages temporarily, and then the qualified catches were selected in the cage.This method was suitable for small pond op-eration with the area between 3 000 and 10 000㎡.It had the advantages of low cost, high efficiency, small damage, and was suitable for the no-damage fishing of parents. |
