架子网选型试验网模水槽试验报告

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，三种典型为参选图，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。

REPORT ON THE MODAL TANK TESTS OF EXPERIMENTAL NETS FOR SELECTIVE TYPE OF STOW NET WITH POCKET

During these few years, many structures of stow net with pocket were successively developed by fisheries scientific and technological workers in an attempt to tackle the damage of large quantity of juvenile fish in stow net with pocket. The most typical types were open, belly-hole and eight-panel types, all of which have their feature in the case of increasing production and releasing juvenile fish. We made experiments on the selective types of stow net with pocket from 1991 to 1992 in order to select an optimal net type. By contrast with the traditional stow net with pocket three kinds of typical net used as candidates were made in real size contrast tests and modal net tank tests, so as to optimize the best net type. This paper focuses on the methods, contents and results of modal net tanktests.
