What are the feeding methods for fish feed? A detailed explanation of feeding techniques for various fish

Feed is one of the biggest costs of @#@233@#@. Using scientific feeding methods not only benefits the healthy growth of fish, but also saves feed and effectively improves fish farming efficiency.

1. Pellet feed: The diameter of fish pellet feed is usually 2.5-8 mm, and the length is 5-10 mm. It can be directly scattered into the fish pond for feeding. If the feed is damp, do not feed it directly. First dry it in the air or in the sun, and then feed it; if the feed has spoiled, it should not be fed again to prevent fish from being poisoned after eating it.

2. Cake-type feed: For feeding small fish, cake-type feed should be crushed, soaked, and ground into slurry before feeding. For feeding medium to large fish, it only needs to be soaked until soft.

3. Grain feed: Large grains such as corn are best crushed before being fed to fish; small grains such as rice grains can be sprouted before being fed to fish. Young grain white sprouts have high nutritional value, are easy for fish to digest, are absorbed quickly, and promote rapid weight gain.

4. Green feed: For feeding medium to large fish, green feed can generally be directly fed after removing the soil; for feeding small fish, it should be chopped or pulped, then mixed evenly with 0.2% salt and splashed in for feeding. After chopping green feed and cooking it, mix in an appropriate amount of bran, and small fish will like it even more.

5. Distiller's grains and bran feed: For feeding small fish, distiller's grains and bran-type feed should be soaked until soft and ground into slurry; for feeding medium to large fish, it is best to ferment it until it has a wine aroma before feeding. At the beginning, feed a small amount first, then gradually increase the amount later, but it should not exceed 30% of the total daily feed amount.

6. Protein feed: @#@254@#@, @#@261@#@, insects, and others are all first-class animal protein feed for fish. They can be fed directly, or dried in the sun and processed into powder to be mixed with other feed for feeding fish. For block-shaped animal feed, it should be chopped and ground finely, mixed with a binder, and made into small balls for feeding.

7. Manure feed: Chicken manure, pig manure, cow manure, and others can all be used as fish feed. Dry the manure in the sun and grind it into powder, then mix it with other feed in a certain ratio. The ratio is generally suitable at 40-50% chicken manure, 50-70% cow manure, and 30-50% pig manure.
