1, feed with seawater, if there is no seawater, need to use salt water to water for feeding, also need to add oxygen to the water.

2, more water change, to avoid water pollution, each time the water change to adjust the salinity of the water,

3, every day regularly feeding food, try to feed to eight full, food can be fish, small shrimp and so on.

A, pike crabs at home how to raise live

1, deepen the water to enough to submerge on the line, while paying attention to the need for seawater feeding, if you can't find seawater, you can use sea salt to water to feed, 24 hours of continuous to the water to increase oxygen.

2, you need to lay soft mud in the pool or planting water plants, usually should also often change the water, to avoid serious water contamination appear infected. But before each water change, you need to adjust the water temperature and sea salinity to the same.

3, every day you need to regularly feed it food, such as fish, nematodes, earthworms, shrimp, etc., and try to control the time of each feeding in half an hour, feeding eight minutes full, and timely control of water quality after feeding.

Second, how much salinity is suitable for breeding pike crabs

1, the appropriate salinity

(1) suitable for pike crabs to live in the salinity of 13-28?, the most suitable for the growth of salinity 20-35?, when it needs to be over-wintered, the appropriate salinity is 28-35?

(2) It should be noted that when the salinity is lower than 8? or higher than 38?, the pike will stop eating and activity, and usually die after 1 day or so.

2, suitable for the growth of the pike crab other conditions

(1) temperature: suitable for the pike crab to live in the water temperature of 15.5-26 ℃, when the temperature of 15-26 ℃, feeding, normal activities and fast growth.

(2) Dissolved Oxygen: Dissolved Oxygen should not be less than 2mg/L.

(3) PH value: PH value should be 7.5-8.
