近年来长江口渔场附近海区中国对虾(以下简称为对虾)、日益减少,加紧探索在长江口渔场附近海区增殖对虾的可行性是完全必要的。为了观察和研究对虾在该水域的河游、繁殖等基本情况,为大规模人工增殖对虾资源提供科学依据,进行一定数量的对虾标志虾放流是一个很重要的手段。所谓对虾标志虾就是在对虾脊背上用针线穿挂一个放流标志牌,而标志虾的制作及放流方法正确与否,直接影响到放流效果,现把一般的方法介绍如下。
In recent years, the shrimp (hereinafter referred to as shrimp) of the shrimp near the estuary of the Changjiang Estuary have been declining steadily. It is absolutely necessary to intensify the exploration of the feasibility of multiplying shrimp in the sea near the estuary of the Yangtze Estuary. In order to observe and study the basic situation of river shrimp swimming and breeding in this water area, it provides a scientific basis for the large-scale artificial propagation of shrimp resources. It is a very important method to carry out a certain number of shrimp shrimp discharge. The so-called shrimp shrimp shrimp logo is on the back of the shrimp with a needle hanging through a flow discharge sign, and the production and release of shrimp logo correct or not, directly affect the discharge effect, now the general method described below.
