Feed is one of the biggest costs of raising fish. Paying attention to scientific feeding methods is not only beneficial to the healthy growth of fish, but also saves feed and effectively improves the efficiency of fish farming.

1. Pellets The diameter of fish pellets is usually 2.5mm~8mm, and the length is 5mm~10mm, which can be directly thrown in the fishing pond for feeding. If the feed is damp, do not feed it directly, it must be air-dried or sun-dried before feeding it; if the feed is deteriorated, it should not be fed again to prevent the fish from being poisoned after eating.

2. Cake-type feed The cake-type feed should be crushed, soaked, and pulped for feeding small fish, and it can be macerated after feeding medium to large fish.

3. Pets analysis, grain feed grains with large grains such as corn should be processed and crushed and fed to fish; small grains such as grains can be sprouted and fed to fish , The young and tender grain white buds have high nutritional value, and the fish is easy to digest, absorb quickly, and gain weight quickly.

4. For medium to large fish, the green feed is generally fed after removing the soil; for small fish, it should be chopped or beaten, and then mixed with 0.2% salt. Sprinkle and feed. The green feed is chopped and cooked, mixed with appropriate amount of bran and soda. Small fish prefer to eat it.

5. For the small fish, the bad bran feed should be macerated and refined; for medium to large fish, it should be fermented until it smells of wine. Feed a small amount at the beginning, and then gradually increase the amount, but it should not exceed 30% of the total daily feeding.

6. Protein feed Earthworms, fly maggots, insects, etc. are all high-quality animal protein feeds for fish, which can be fed directly, or dried and processed into powder to feed fish with other feeds. For block animal feed, it should be chopped and ground finely and fed into small clumps by adding binders.

7. Manure feed Chicken manure, pig manure and cow manure are good feeds for fish. The feces are dried and ground into powder, and then used with other feeds in a certain proportion. The proportion is generally 40% to 50% of chicken manure, 50% to 70% of cow manure, and 30% to 50% of pig manure.
