1, refrigerator storage
Put the crayfish into a basin with a suitable size, then pour in a proper amount of water, add a little ice cubes, cover the basin with a breathable rag to ensure air circulation and avoid odor, and finally put it into the refrigerator, the temperature is about 1-2 degrees, and the activity rate of crayfish can be reduced by low temperature, so that crayfish can be kept and fed overnight.
2, big pots to feed and preserve
Crawfish are spread out in large pots, and then a proper amount of water and a little ice cubes are put in the big pots, and the amount of water should not exceed the head of crayfish, which can be about 2-4 cm. They should be placed in the shade to avoid high temperature, and large black plastic bags or other things can be covered on the pots to create a dark and humid environment, so that crayfish can relax and sleep, and reduce activities.
During the period, you can add ice cubes to keep the temperature low, and feed on vegetables, steamed bread, diced meat and other foods for 1-3 days, and some can even feed for a week, but the meat quality may be reduced due to insufficient nutrition in the later period, so it is better to eat as soon as possible.
Method of selecting crayfish
1, look at the color
Look at whether the crayfish is clear water or muddy water. When you look at the back, it is bright red and clean, which is acceptable. Then look at the fluff on its abdomen and the hairs on its claws. If it is white and neat, it is basically raised by clean water.
2. Look at the size
Try to buy lobsters that have just grown up. After all, they are too small and tasteless to eat. Touch their shells with your hands. Hard and hard are old, and those that are as elastic as nails are just changed when they grow up, so we want to buy soft shells.
3. Look at the male and female
Crayfish is divided into male and female. The male crayfish has a big clip and a small body, that is, less meat, but more yellow shrimp. The female crayfish clip is slightly smaller and fleshy. Picking crayfish is very knowledgeable, and the price of all female crayfish is slightly more expensive than that of the public.
