You need to pay attention to the following conditions when raising lobsters:

1. Water temperature: Lobsters live in lower water temperatures. The lowest water temperature in winter is about 5℃-6℃, which is suitable for lobster farming. If the water temperature Lower, the maturity period will be extended to 5-7 years. The suitable temperature for growth is 20℃-23℃. Lobsters grow fastest in water at this temperature. Therefore, in winter when the water temperature drops, using warm drainage to raise them is one of the ways to promote growth.

2. Salinity: The suitable salinity range of lobster is 26.90‰-34.40‰, and it can live and metamorphose in seawater with a low salinity of 23.50‰.

3. Substrate: In order to escape the predation of natural enemies, lobster larvae turn to the benthic life. The gravel of the substrate is extremely important as a place for lurking and feeding. Three to four days after metamorphosis, lobsters can burrow and lurk in sand with a particle size of 0.4 to 1.00 mm. After 8 days of metamorphosis, it can lurk in sand with a particle size of 2.0-3.0 mm.

4. Growth rate: For lobster groups before the age of 1, only oyster shells are needed to line the bottom of the pond. There is no need to put in artificial shelter nests, and purple mussels are fed as bait. Starting from the 2nd age, perchlorethylene pipes are put in as shelter nests, and the number of them is twice the number of lobsters raised.

5. The impact of water quality on lobster production cannot be ignored. The quality of water directly affects the healthy growth and development of lobster. During the breeding process, the pH value of the water should be maintained at 7.5-8.5. Between them, the transparency is 30-40 centimeters. New water should be added frequently, quicklime solution should be splashed regularly, and the water quality should be adjusted to prevent the occurrence of diseases and unsuccessful shelling.

6. Reasonable feeding of feed: The feed of lobster is animal and plant feed. The plant feed is wheat, aquatic grass, rapeseed cake, etc., and the animal feed is miscellaneous fish, miscellaneous meat and livestock offal.

Extended information:

Lobster is the general name for species under the family Lobsteridae of the phylum Phylum Arthropoda and the order Decapod. Also known as prawn, faucet shrimp, shrimp king, sea shrimp, etc. It has a thick cephalothorax, hard shell, colorful body, short abdomen, body length is generally between 20 and 40 centimeters, and weighs about 0.5 kilograms. Some parts of it have no chelae, and the abdominal limbs can evolve into chelae.

The heaviest one can reach more than 5 kilograms, and is known as the lobster tiger. The body is thick cylindrical, dorsally and ventrally slightly flattened, the head and chest carapace is well developed, thick and spiny, and there is a pair of powerful supraocular spines in the center of the front edge with closed gill chambers. Mainly distributed in tropical waters, it is a valuable seafood.

Lobster has a strong ability to tolerate hypoxia. In anoxic water environment, it can climb ashore and perform gill respiration to survive. The pH value of water quality is in the range of 5.8 to 9, and it can still survive normally when the dissolved oxygen is lower than 1.5mg/L. Normal growth requires dissolved oxygen to be above 3ml/L.
