1, pike crabs can be farmed. 2, prepare brackish and pollution-free water, pond flooding depth of no more than 6 meters, put some small fish and shrimp and so on. 3, retain a part of the land area, laying a moderate amount of sand, so that pike crabs can bask in the sun, throw sand. 4, drain the pond water, clean up the bottom of the silt, can be placed under the water in the bottom of the water bottles and other containers. 5, put the size of the Different seedlings are placed separately, and the water temperature of the pond should not be lower than 20℃.

A, pike crabs can be farmed

1, pike crabs can be farmed

Pike crabs can be farmed, but farming is more difficult.

2, the morphological characteristics of the pike crab

(1) The pike crab is called in some places ? White crab? , aliases are triton pike crabs, gun crabs, sea crabs, sea crabs, etc., belonging to arthropods.

(2) Pike crabs in the male umbilicus pointed and smooth, chelipeds grow, shell surface with cyan, female umbilicus round with velvet, shell surface ochre, or spots.

(3) Pike crabs have high nutritional and economic value, suitable for mariculture, body color will vary with the surrounding environment.

(4) Pike crabs are distributed in Japan, Korea, the Malay Archipelago, the Red Sea and most of the coastal areas of mainland China.

Second, the pike crab breeding methods and conditions

1, the preparation of the pond

(1) pike crabs are suitable for growth in seawater, to be prepared for brackish water, and non-polluting water quality, irrigation, the depth of water is not more than 6 meters.

(2) You can put some small fish and shrimp in the water to provide natural food for pike crabs.

(3) Pike crabs like to sunbathe on the shore, and when establishing the pool, a part of the land area can be left to meet its preferences. A moderate amount of sand can be spread on the land to satisfy the pike crab's habit of throwing sand.

2, pond disinfection

(1) Before the seedlings are launched into the water, the pond should be drained and the silt at the bottom removed, leaving only a small part.

(2) You can put some water bottles and other containers at the bottom of the pond to provide a more suitable adjustment space for the pike.

(3) After cleaning up the pond, you can inject the right amount of water. At the same time, apply the appropriate amount of fertilizer, a few days later you can put the pike crab seedlings.

3, put crab seedlings

(1) Because the crab likes to scramble for the characteristics of the crab, when putting seedlings, the crab seedlings according to the size of the separate feeding.

(2) The temperature of the pool should not be lower than 20℃, and there should not be too much change up and down, and the water temperature should be adjusted strictly according to the change of air temperature.

4, daily management

(1) In addition to timely adjustment of the water temperature, you also need to replace the pond water in a timely manner. When the climate is hot in summer, you need to change the water 2 times a week.

(2) When the climate is hot, the pike's appetite will be reduced, you can feed some pike like small fish and shrimp and other food to maintain their nutritional needs.

(3) Pay attention to the oxygen content of the pool, when the oxygen is less, it may cause the pike crabs to die in a large area.
