Xiaoqinglong (crayfish): water temperature 17- 18℃, salinity 24-26%. Generally, it can survive for 3-4 days. You can mix lobster.
Dolphin and saury: water temperature 18- 19℃, salinity 16- 18%. Feed 15 days at most, and change the water once a week. They can be mixed.
Chinese mitten-handed crab, rare crab, swimming crab and cream crab: water temperature 17- 19℃, salinity 23-24%. Generally, it can live for 7 days, and all crabs can be mixed.
Meretrix meretrix: water temperature 13- 15℃, salinity 12- 15%. They can live for about five days. Generally, they are fed by running water, and there are no contraindications for mixed culture of these shellfish, but they are placed separately because of their small size.
Sturgeon, stickleback and shrimp: water temperature 12- 15℃, salinity 0. Because sturgeon is fierce, it needs to be fed separately, and other species can be mixed.
Shrimp, Neopenaeus monodon, snail shrimp and grass shrimp: water temperature 18- 19℃, salinity 16- 18%, and can live for 1-2 days at most. Because shrimp can easily deteriorate the water quality, it should be changed every 1 day. Because hotels feed a lot, they usually feed them alone.
Left-handed fish: the water temperature is about -2℃ and the salinity is 24-25%. Can feed 15 days at most, and need to change the water once a week.
Scallop, scallop, mussel and snail: water temperature 0℃, salinity 18-20%. They can be kept for up to 3 days and are usually fed with tap water. These shellfish generally have no contraindications to polyculture, but they are all placed separately because of their small size.
Raw materials for spots such as East Star Spot, Stone Spot, Su Mei Spot, Rat Spot and Tiger Spot: the water temperature is about 20℃ (constant temperature is required in winter) and the salinity is 24-26%. Generally, change the water once a week, and you can mix the rest.
Mytilus: The water temperature is about -2℃ and the salinity is 24-25%. Generally, it can be stored for 5 days, and the water is changed once every 2 days on average. Can be mixed with left-handed fish.
California bass: the water temperature is 23-28℃, although the origin of California bass is pure fresh water; However, as long as the salinity is kept below 10%, it can generally survive for 20-30 days, change water once a week, and can be mixed with other fish species.
Live abalone: water temperature 12- 15℃, salinity 10- 12%. It can be stored for 15 days at most, and the water is changed once every five days on average. Generally, it is fed alone.
Live sea cucumber: the water temperature is about 15℃ and the salinity is 10-22%. It can be stored for up to 3 days, and the water is changed once every 2 days on average. Generally, it is fed alone.
Meretrix meretrix, snail, Meretrix meretrix and swan egg: the water temperature is 65438 00℃ and the salinity is about 65438 02%, which can be stored for up to 5 days. Generally, these shellfish are fed with running water. Generally, there is no contraindication to polyculture, but they are raised separately because of their small size.
Extended data
Advantages of mariculture:
Focus on developing some fish, shrimp, shellfish and echinoderms (such as Stichopus japonicus) with high economic value, short production cycle and high yield per unit area. According to the breeding objects, it can be divided into fish, shrimp, shellfish, algae and seafood, among which shellfish and algae develop rapidly; Shrimp, fish and soft seafood are all weak. According to the spatial distribution, it is divided into beach, harbor, shallow sea and other marine cultures. According to the degree of intensive cultivation, it can be divided into intensive cultivation (including nursing and trusteeship), semi-intensive cultivation and intensive cultivation, with intensive cultivation as the main one.
