Lobsters mainly inhabit the sandy and muddy seabed, with one tail lurking in each hole. However, in the mating period, males and females pair up and sometimes lurk in the gaps of rocks, while Japanese lobsters live in groups. Lobsters must be fed during feeding, and it is necessary to consider whether various attached organisms can be used as bait.

1, water temperature: lobsters live in low water temperature. The lowest water temperature in winter is about 5℃-6℃, which is suitable for lobster culture. If the water temperature is low, the maturity will be extended to 5-7 years. Lobster has poor high temperature resistance. In the experiment, the water temperature was raised to 25℃, and there was no special abnormality for 2 weeks. According to the experiment, the suitable growth temperature is 20℃-23℃, and lobster grows fastest in water with water temperature of 20℃-22℃, so in winter when the water temperature drops, it is one of the methods to promote growth by using warm drainage.

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

3. Bottom material: In order to avoid predation by natural enemies, the metamorphosed larvae of lobsters turn to benthic life, and the sand in the bottom material is extremely important as a place for lurking and feeding. After metamorphosis for 3-4 days, lobsters can burrow and lurk in sand with a particle size of 0.4- 1.00 mm. After 8 days of metamorphosis, it can lurk in sand with a particle size of 2.0-3.0 mm.
