Brittle Anhui fish farming methods include farm site, brittle feeding, regular water changes, and live water molding.

1. Farming site

Brittle grass carp have very high requirements for the breeding environment. The breeding pond requires sufficient water, good water quality, easy access to the drainage, the bottom of the pond sediment, pond slope 1: 3. The most important thing is that the depth of the breeding pond must be more than 2.5 meters, one to give the fish enough space to swim, and the other can keep the water temperature below 20 ℃, because of the nature of the grass carp is afraid of the heat and like the cold.

2, crispy feeding

Crispy carp is fed with grass carp. The first phase of the breeding in full accordance with the feeding of grass carp, about one and a half years of feeding on the time, grass carp grow to about 5 pounds, then began to crispy breeding. Brittle culture is to change the feeding feed, mainly feeding pure natural northeastern broad beans.

Fava beans don't need to be crushed, the whole material is soaked in water for more than a day and night, so that it is soaked through the softened and swollen, which is easy for the grass carp to ingest and digest. After the grass carp ate the beans, the cell density increased, the cell wall thickening, that muscle inside the collagen content than the ordinary grass carp increased dozens of times, so it will become brittle. Usually after 4 months of feeding, grass carp become crispy grass carp.

3, regular water changes

Brittle grass carp is also very demanding on water quality, not only requires fresh water, dissolved oxygen is sufficient, and the dissolved oxygen in the breeding pool can not be less than 5 mg per liter.

So the breeding process should be regularly fresh and cool water, in the spring and winter when the temperature is low every five days to change the water, if the temperature is high in the summer, the oxygen in the water volatilization fast, fast bacterial growth, it must be 2 to 3 days to change the water, the best water citation water quality reservoirs, mountain streams, water, you can also use the river water, but it must be to ensure that the water quality is fresh and pollution-free.

4, live water body shaping

To make the crispy grass carp meat more crispy, we have to let them transported up, and often introduce running water, in the flow of the pool water, so that the fish quickly swim, jump, surf in the pool, reduce fat accumulation, increase muscle toughness.

So, crispy feeding, in addition to ensuring the feeding of a sufficient amount of fava beans, but also to ensure that they have enough space to move and a lot of movement to make the meat crispy, and the water temperature in the pool can not be higher than 25 degrees, the temperature is too high, the fish will not become crispy.
