The crayfish crayfish has strong vitality and strong resistance. It should not be problematic for its temporary conservation. Even if the summer crawfish can survive for a long time in water, generally only a small amount of water needs to be raised. Yes, if it is inflated, it is easier to transport and hold, but if the soft-shelled shrimp (shrimp just after shelling or shortly before the shrimp) has a low survival rate in transportation and holding, it should be selected.
The real lobsters are the lobsters of the American lobsters and European lobsters. Broadly speaking, it also includes langoustines and Norwegian langoustines, Japanese lobsters such as Spanish lobsters, coral lobsters and clams. Sometimes it also includes freshwater crawfish. The crayfish generally inhabit the sea floor from the extremely shallow sea area several meters deep in the coastal waters to the coastal sea areas with different water depths. The crayfish adaptability to low water temperature is very strong, as long as the sea water does not freeze, the average individual can survive.
Lobster is one of the current high-end aquatic products, and its price is high. In the non-products of European and American countries, the value of crayfish is the highest. According to the biological characteristics of lobsters, the following points should be noted during the larval rearing process: 1) The salinity should generally be controlled at 15 ‰ or more, because most of the lobster captured in the sea lives in the salinity of 15-20 ‰. In order to facilitate temporary support; 2) Temporary water temperature can be reduced to about 10-15 °C, but the cooling can not be too fast, making it a process of adaptation, breeding at low temperatures can reduce its activities and losses; 3) relatively fresh The quality of water, lobster in its natural environment, the water quality is relatively good, can be used in the aquarium tank filtration equipment to maintain clean and excellent water quality; 4) adequate dissolved oxygen, lobster oxygen requirements are higher, so In the process of temporary breeding, oxygen must be supplied; 5) The stream lobster prefers to live in the environment with water flow, so the condition of flowing water should be caused during the holding process, and the small water pump can be used to circulate the water; 6) Substrate and perch The quality of sandy bottom or coral bottom or gravel bottom is better; if the time of temporary breeding is longer, the density should not be too large. It is better to have some hidden inhabitants, which is more suitable for a longer time. Holding.
