Freshwater grouper culture technology: the latest technology of grouper culture, grouper culture technology and environment

Freshwater grouper is rich in nutritional value, is a very special fish, it not only has economy, but also the role of ornamental, the scale of culture is also getting larger and larger, and gradually become a new species of freshwater culture. Freshwater grouper is a kind of tropical fish, generally grows in fresh water, is partial carnivorous fish, freshwater grouper can adopt mixed culture. Let's take a look at how to raise it.

Culture methods of freshwater grouper

1. Pond arrangement: the bottom of the pond is sandy and there is no pollution in the surrounding sea area. Some water tanks, tires or pebbles can be laid at the bottom, because freshwater grouper has the habit of drilling holes.

2. Fish fry stocking: when a small amount of mixed culture is in the pond, there are about 22 million fish per mu of water surface. When the main fish is freshwater grouper, tilapia, grass carp, crucian carp and so on can be mixed cultured, and 150 ~ 200 freshwater grouper per mu of water surface.

3. Domestication of fish fry: surimi can be fed on the table when it reaches more than 3 centimeters, and a small amount of artificial formula feed can be added 2-3 days later, and then gradually increase the proportion of artificial formula feed until all artificial formula feed is used.

4. Feed feeding: the daily feeding amount is about 20% of the body weight of the fish, usually 3 times a day.

5. Feed selection: the protein content of artificial formula feed is 3540%, animal protein should be more than 25%, and other plant protein raw materials can be added.
