近几年,水产科技工作者相继研制出多种结构形式的架子网,试图解决架子网大量损伤幼鱼问题,最典型的有开口式、腹洞式、八片式三种,这些网在增产和释放幼鱼方面各具特色。为了选出一种最佳网型,我们于1991至1992年进行了架子网选型试验。选型以传统架子网为参照,三种典型为参选网(见网图1～4),分别进行实网生产对比试验和网模水槽试验,优选出最佳网型。本文着重介绍网模水槽试验方法、内容及结果。
In recent years, aquatic science and technology workers have developed a variety of structural forms of shelves in order to solve the large number of shelf nets juvenile problems, the most typical open, abdomen hole, eight slice three, these networks in the increase And release juveniles have their own characteristics. In order to choose the best mesh type, we carried out the selection of shelves from 1991 to 1992. Selection of traditional shelves for the reference frame, the three typical network for the election (see Figure 1 to 4), were compared net production test and net mold sink test, select the best network type. This article focuses on the network die sink test methods, content and results.
