1. Preparation: soak in warm salt water for the first time 1-2 minutes to remove parasites or lice, then put a pot and cover it with a shelter, and spread the bottom sand. 2. Keep the light: put the basin near the window as much as possible, or where the sun can shine obliquely. 3. Feeding container: 1 A comfortable living environment must be provided for sea crabs, and plastic boxes or glass boxes can be used.

First, how to raise sea crabs without dying?

1, preparation work

(1) When breeding, soak 1-2 minutes in warm salt water, which is beneficial to remove parasites or lice. Then put a pot, cover it with a shelter, and spread bottom sand, and you can add 1-2 spoonfuls of calcium salt on it.

(2) New crabs usually get into the sand, and they will adapt to the new environment in a few days or weeks, and they will not be very active at that time.

(3) After they are familiar with the environment, they must not disturb them often. They should be placed in a dark and quiet place, change food every day and keep proper temperature and humidity.

2. Keep the light.

(1) Sea crabs should be placed near the window or in the sun as far as possible, but the light should not be too strong. You can put the cylinder in a lower position, and the highest edge of the cylinder is just at the lowest edge of the window.

(2) There must be more hidden objects in the cylinder, which can conform to their habits. Sea crabs are timid, and hiding things can make them feel safe.

3. Feeding container

(1) In order to provide 1 a comfortable environment, you can choose plastic boxes or glass boxes.

(2) The plastic box must be attached with a cover and have a certain height to prevent the sea crabs from escaping. The cover should be perforated and properly ventilated.

4. Space

(2) There should be 1 layer bottom sand in the feeding tank. The function of bottom sand is to let them have a suitable place to shell. The depth of bottom sand in the cylinder must be 1-2cm, and the sand thickness is about 2-3 mm. Generally, sand that is too young will be sucked into the shell, and sand that is too coarse will make them unable to return to the sand surface after molting.

(2) If you want to expand the space of the feeding trough, you can put some climbing plants or driftwood in the feeding trough for them to climb.

2. When is the sea crab the fattest?

1, sea crabs are generally the fattest in March-April. The most delicious female crab is produced from the end of September to the beginning of 10, and the male crab is about 1 10. Generally, the autumn of 10- 1 1 is the best time to eat sea crabs. It is better to eat female crabs in August in lunar calendar and male crabs in September in lunar calendar.

2. When eating sea crabs, you should pay attention to the fact that things like eyebrows in the abdomen of crabs must not be eaten. It is the respiratory organ of crabs, mainly used to filter water quality, and the crab white under the gills is not suitable for eating. There is crab excrement in the crab intestine. After opening the crab, you can see that there are 1 black things in the crab yellow and crab meat. You must take them off before eating.

3. Sea crabs mainly inhabit the offshore shallow sea, with the highest density in the sea area with water depth of 10-50m and sediments of 10-30m. In winter, sea crabs hibernate in the deep seabed. They belong to wide-temperature aquatic animals, and the suitable water temperature is 17-30? C, the optimal growth water temperature is 25-28? C.
