What feed should be fed to hairy crabs? How are hairy crabs raised?

Hairy crabs are the best river food to eat in September and October. Hairy crabs and other crab foods are best eaten fresh. If you buy too much, you might as well feed them while you eat them. In order to ensure the fat meat of hairy crabs, the bait is also particular and can't be fed casually. So how do you feed hairy crabs?

What kind of feed should be fed to hairy crabs?

The mainstream bait for hairy crabs now is natural animal and plant baits such as snails, small fish, corn, and wheat, which are a combination of meat and vegetables and have balanced nutrition. Some breeders also use artificial synthetic feeds to feed hairy crabs with natural baits.

Moreover, the combination of bait is also very particular. When should you eat more meat and when should you eat more vegetables? These ratios will affect the growth and development of hairy crabs.

The ratio of bait varies according to the different growth stages of hairy crabs.

Some experienced breeders will adopt a feeding method of "fine at the two ends and coarse in the middle". In the early and late stages of the growth of hairy crabs, they will mainly feed them with animal baits such as small fish and snails, supplemented by wheat and corn. In the middle stage of the crab's growth, the weather is hot and the water temperature is high, so they should do the opposite, and try to feed them with plant baits as the main bait and animal baits as the supplement.

This feeding method is in line with the growth habits of hairy crabs, can effectively fatten hairy crabs, and can avoid hairy crab diseases caused by high temperatures.

How are hairy crabs raised?

Sufficient food

The feeding is mainly composed of granular feed and frozen sea fish, with appropriate additions of water plants such as Hydrilla verticillata, Vallisneria, and snails to balance nutrition and increase the activity of crabs.

Only by roughly calculating the daily feeding amount for hairy crabs and combining it with observation can we feed enough and not too much, feed accurately, meet the nutritional needs of hairy crabs for normal growth, improve the survival rate, and increase the growth specifications.

Good water quality environment

Use microbial preparations every 15 days to improve the water environment, and regularly measure algae and plankton in the water. If the number of harmful algae such as cyanobacteria, bell-shaped algae and bell-shaped insects increases, use drugs to kill algae and insects with caution, and take measures such as frequent water changes and supplementation of beneficial algae to inhibit the reproduction and growth of harmful algae.

Open breeding environment.

About 550 crab seedlings weighing 3-4 grams are released per acre to give the crabs enough space to move around.
