无公害养鱼除饲料等投入外,关键措施在于鱼病防治。现结合生产实践,将一些具体方法介绍如下:一、共生环境。研究发现水生植物与鱼类同池共生,鱼类很少生病,这就为无公害养鱼找到了突破口。在鱼池中,多种植水生植物,如水稻、莲藕等,具体要求为:呈东西走向,行距宽约33厘米,占水体 Pollution-free fish in addition to inputs such as feed, the key measure is to prevent fish disease. Now combined with production practices, will introduce some specific methods are as follows: First, the symbiotic environment. The study found that aquatic plants co-exist with fish in the pool, fish rarely sick, which found a breakthrough for pollution-free fish. In fish ponds, planting more aquatic plants, such as rice, lotus root, etc., the specific requirements are: east-west direction, about 33 cm spacing, accounting for water
