Ecological fish-farming method

Abstract

The invention relates to an ecological fish-farming method. The method comprises the following steps: 1) fish pond construction; 2) fish pond treatment; 3) fry stocking; 4) water quality management; and 5) feeding management. The method provided by the invention adopts an ecological circulation mode of flowing water culture and a mode of imitating natural growth, and cultured fish have good quality of fish, a high yield, and a low incidence rate; through the flowing water culture, no chemical drugs are used for sterilization and disinfection, water quality is good, and the cultured fish have afast growth speed and strong disease resistance; and aquatic animals and plants and artificial biological feed are mainly used, so that the cultured fish have fresh and delicious fish and high quality, and breeding benefits and ecological benefits are increased.

Description

technical field [0001] The invention relates to the field of fish farming, in particular to a method for ecological fish farming. Background technique [0002] In my country, the aquaculture output of the four major carp herring, grass carp, silver carp and bighead carp accounts for about 80% of the total output of freshwater aquaculture species, and they are important food materials for people's daily life. Traditional breeding ponds are mostly earthen ponds. Over time, the ridges of the ponds tend to age and collapse, and the silt at the bottom of the ponds accumulates too deep. The breeding capacity of the ponds is getting smaller and smaller, and the breeding environment is deteriorating. Moreover, current fish culture adopts static water culture more, and the pond water is in a stagnant state. The method of regularly changing the water is about to keep the water in the fish pond for several days, and change the water thoroughly every other stage, such as 6-15 days. Ho...

However, this method can still cause fish diseases in high temperature seasons, perhaps caused by incompletely sterilized bait or introduced water

Once a fish disease occurs, it can only be treated with chemical drugs, which will damage the taste of the fish and human health.

At the same time, in the breeding process, feed is mainly used for feeding. The amount of feed is large, the cost is high, the yield is low, and the benefit is poor. The taste of fish fed with artificial concentrated feed is worse than that of naturally grown fish. High-quality consumer market demand
