Generally, there is no contraindication to polyculture of these shellfish, but they are all placed separately because of their small size.
The raw materials of spots such as East Star Spot, Stone Spot, Su Mei Spot, Rat Spot and Tiger Spot: the water temperature is about 20℃ (thermostat is needed in winter) and the salinity is 24-26%. Generally, the water is changed once a week, and all the others can be mixed.

Extended data
Advantages of mariculture:
Focus on the development of some fish, shrimp, shellfish and echinoderms (such as Stichopus japonicus) with high economic value, with short production cycle and high output per unit area. According to the culture objects, it can be divided into fish, shrimp, shellfish, algae and marine treasures, among which shellfish and algae have developed rapidly; shrimp, fish and soft marine treasures are weak. According to the spatial distribution, it is divided into marine culture such as beach, harbor and shallow sea. According to the intensive degree, it can be divided into rough cultivation (including nursing and custody), semi-intensive cultivation and intensive cultivation, with rough cultivation as the main one.
