What to eat when raising crabs, what food to eat and how to raise crabs

Crabs raised at home can be fed with special feed, and can also be fed with bread worms, fish and shrimp, bloodworms, earthworms, lean meat, cabbage, dried beans, bitter grass, elosa and other foods. The feeding temperature should not be lower than 10 degrees, and 20-28 degrees is the most suitable for their growth. Occasionally, sprinkling salt in the fish tank can be effective in preventing infectious diseases.

If the crabs that have just arrived at home do not eat, they can be fed after a few days of starvation.

Crabs like to eat fresh ingredients. For this reason, the daily feeding management prohibits those feeds that have been stored for a long time and deteriorated. When feeding, it is necessary to put meat feed as the mainstay, and use some nutritious vegetarian food in moderation, especially more plant-based feed.

This ensures good water quality in the pond. The number of times the material is used should be determined according to the change of climate temperature. In the hot summer, feeding is sufficient at 2 times.

The exact amount depends on the weight of the crab. If there is any uneaten residue, it should be salvaged immediately to avoid deterioration affecting the water quality.

You can raise it in a basin, it doesn't matter if the water is deep or shallow, it won't drown it. However, it is better to have water freshly soaked in the shell. You can let it bask in the sun, don't bask it for too long.

You can use tap water for water, but you don't need to use it until you dry it for a day. It is also necessary to adjust the water to salt water of concentration, because it is a sea crab, so it must be raised in salt water.

Crabs are omnivorous.

You can feed them fish, whether it's raw or dried. They may also be fed fish feed, bloodworms, dried shrimp, snails, mussels. It is best to feed some grass-based foods frequently, such as bitter grass, eloso, etc.

As long as the feeding is OK, there is no need to worry about the rest, the sea crabs are very easy to raise.

There are three main types of feed.

Full-price special compound feed for river crabs;

Animality: sea and freshwater small trash fish, animal carcasses, snails, mussels, livestock and poultry blood, fish meal, silkworm pupa, etc.;

Plant-based: aquatic weeds, duckweed, water peanuts, bitter grass, black algae, etc., commercial feed: yams, potatoes, cereals, bran, bran, etc.

The feeding method of river crabs is like pond fish farming, so as to achieve "four looks and four determinations", that is, to see the season, the weather, the water quality, and the activities of the crabs, timing, fixed, qualitative, and quantitative.

Adult crabs prefer a water body environment with clean water quality and greater transparency, with abundant aquatic weeds and abundant bait, and river crabs are the most suitable for growth, and most of them are cultivated in ponds, lakes, rivers and paddy fields.

Food: (1) Full-price compound feed for river crabs;

2) Animality: sea and freshwater small trash fish, animal carcasses, snails, mussels, livestock and poultry blood, fishmeal, silkworm pupa, etc.;

3) Plant-based: aquatic weeds, duckweed, water peanut, bitter grass, black algae, yam, potato, cereals, bran, bran, etc.

Skills: (1) Look at the weather: when the weather is sunny, you should feed more, and on rainy days, you can stop feeding, foggy days, and wait for the fog to be harvested before feeding.

2) Look at the water quality: the water quality is clear, the bait can be fed normally, the water quality is strong, the feeding should be reduced appropriately, and the water should be changed in time.

3) Look at the activity of the crab: generally eat up the next morning after feeding, the amount of bait is appropriate, not all, indicating that the crab appetite is not strong or the number is too much, the reason should be analyzed in time, reduce the amount of feeding, and the crab should appropriately increase the amount of feeding during the molting period.

4) Qualitative: River crabs are sensitive to fragrant, sweet, bitter, salty, smelly and other tastes, and the feed must be fresh and palatable and rich in protein.

5) Quantitative: "Fish do not eat for a day, do not grow for three days", the same is true for crabs, which requires the amount of feeding to be determined according to the size of the crab, density, different seasons, weather, and activities, and the general daily feeding amount is 8 10% of the body weight of the crab in the pond.
