综合养鱼是一种节能、低耗、高产、高效的养鱼方法,要因地制宜,做到合理布局和有效配置。下面介绍几种综合养鱼的好模式。一、鱼——鸭结合。一般是用旧网片遮拦部分水面养鸭。放鸭密度为每平方米水面3～4只。一只鸭年产粪40～50公斤,可转化成3～5公斤鲜鱼。一般每亩水面配养蛋鸭100～200只,或肉鸭100～120只,其粪便及溅落的饲料可生产鲜鱼300～500公斤。二、鱼——猪结合。主要配置方式有塘边建
Integrated fish farming is an energy-saving, low-cost, high-yielding and efficient method of fish farming, which should be well adapted and effectively configured according to local conditions. Here are some good patterns of integrated fish. First, the fish - duck combination. The old mesh is usually used to cover part of the surface of the duck. Put duck density of 3 to 4 water per square meter. A duck annual dung 40 ~ 50 kg, can be converted into 3 to 5 kg of fresh fish. Generally, there are 100-200 egg ducks per mu of water surface or 100-120 ducks, and 300-500 kilograms of fresh fish can be produced from their excrement and splashed feed. Second, fish - pigs combined. The main configuration has pond construction
