为了使青虾养殖业健康、快速发展,结合我市青虾养殖情况,本人认为必须做好以下几个方面。 一、虾池条件 1、虾池选择。应选择交通便利、电力充备、水源充足且水质清新无污染的地方。由于青虾耗氧量高,不耐低氧环境,又属底栖动物,游泳能力差,常喜在池塘底部或岸边活动,故池塘以1500—3500平方米为宜。面积太小,波浪作用不强,且水质难控制,易缺氧泛塘。面积过大,除野选捕不便,部分到了生命周期的青虾自然死于塘内,造成损失。另外虾池太大,常有几代虾同塘现象,密度难掌握。
In order to make the shrimp farming healthy and rapid development, combined with the city of shrimp farming, I think we must do the following aspects. First, shrimp pond conditions 1, shrimp pond choice. Should choose convenient transportation, power supply, adequate water and fresh water pollution-free place. As freshwater shrimp oxygen consumption, impatience with hypoxia, and is a benthic animal, swimming ability is poor, often like the bottom of the pond or shore activities, so the pond to 1500-3500 square meters is appropriate. Area is too small, the role of wave is not strong, and difficult to control the water quality, easy to hypoxia Pan Tong. The area is too large, in addition to wild catching inconvenience, some of the life cycle of natural shrimp died in the pond, resulting in loss. In addition the shrimp pond is too large, often several generations of shrimp pond phenomenon, density difficult to master.
