How to keep hairy crabs for a long time

If the temperature is not high, the hairy crab can be placed in a deep bucket with a smooth inner wall (not stacked). Add no more than half of the hairy crab with water after putting it in, so it can be stored for 3-5 days. If the temperature is high, tie up the feet and gates of hairy crabs, put them in the freezer of the refrigerator, and cover them with wet towels.

Attention to hairy crab culture:

1. Area

A large area of breeding land will be more conducive to the growth of hairy crabs, but if the area is too large, the management of hairy crabs will cause a greater burden. Therefore, the area is within the scope of science, choose a larger area. Under the condition of 50-100mu of land, 2000-3000 animals per mu are stocked. In addition, in the pond, you can also choose to raise some grass carp, silver carp and other fish to help increase the biodiversity of the river pond.

two。 food

Hairy crab bait, generally choose natural feed as the main feed, can be small miscellaneous fish, and then appropriately add some artificial feed on it. The feeding time is: one in the morning and one in the evening before the first ten days of July; one every other day from mid-July to the end of August in the evening; and one every day from early September to early November and in the evening.

3. Daily management

It is necessary to inspect the crabs sooner or later, observe the feeding, activity, molting and water quality changes of the young crabs, and take timely measures to find abnormalities. In addition, when adding water in the rain, we should strictly prevent the young crabs from escaping from the top water, and set up anti-rodent nets and anti-rodent equipment around the pool to prevent rats from preying on young crabs.

Although it is not yet the best season for hairy crabs, the preservation method can still be well understood.
