The preservation methods of river crabs are: room temperature preservation, refrigerator freezing method and so on.

1, room temperature preservation

If the room temperature can be maintained between 15 degrees and 25 degrees, it is completely possible to put the crabs into room temperature storage. We only need to put the crabs into a larger pot, and then regularly spray them with some water to maintain humidity, so that the crabs can also be preserved for 3 to 5 days, and it is very convenient to take them as you eat them.

2, refrigerator freezing method

According to the size of the refrigerator freezer to choose the foam photo paper, the legs of the river crab tied, put into the foam box. One by one, put it next to each other, add water to the box not more than the crab can be, cover the lid and put it into the refrigerator freezer, want to eat when you take it out of the thawing can be, this method can keep the freshness of the crab, and save time for a long time.

Precautions for breeding river crabs

1, strengthen the moult management

The first moult of river crabs is very critical, which has a direct impact on the annual yield. Before the first molt, you can lower the water level, increase the water temperature, early feeding time of river crabs, to restore their physical condition. During the peak shelling period, the pond environment should be kept relatively quiet, and the feed feeding quantity should be reduced moderately. Drugs and fertilizers should be avoided during the concentrated period of moulting of river crabs.

2, reasonable baiting

Feed feeding in accordance with the "before and after the fine, the middle of the green" principle of baiting and "four" feeding method of scientific feeding, the whole process of breeding feed arrangements focus on animal feed and pellet feed, supplemented by plant feed. The feed arrangement of the whole breeding process is focused on animal feed and pellet feed, supplemented by plant feed. The amount of bait should be adjusted according to the natural feed, season, water temperature and other conditions to ensure that the river crabs eat well.
