What is the salinity table of various seafood cultures?
Australian lobster: the water temperature is 12- 15℃ in summer, 18- 19℃ in winter, and the salinity is 24-26%. Generally, lobsters can live for one week, and the water can be changed every three months without muddy water, because Australian lobsters are vigorous and active.

Xiaoqinglong (crayfish): The water temperature 17- 18℃ and the salinity are 24-26%, and it can generally survive for 3-4 days. Can be mixed with lobster.

Dolphin and saury: water temperature 18- 19℃, salinity16-18%, feeding for up to 15 days, changing water once a week, and they can be mixed.

Eriocheir sinensis, rare crab, swimming crab and cream crab: water temperature 17- 19℃, salinity 23-24%, generally can live for 7 days, and all crabs can be mixed.

Clams and clams: water temperature 13- 15℃ and salinity12-15%, which can live for about 5 days. Generally, they are fed with running water, and these shellfish are generally not contraindicated for mixed culture, but they are small.

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, metapenaeus ensis, snail shrimp and grass shrimp: water temperature 18- 19℃, salinity 1 6-18%, and they can live for 1-2 days at most. Because shrimps easily deteriorate the water quality, they can live every/. Because hotels feed a lot, they usually feed alone.

Left-handed fish: the water temperature is about -2℃ and the salinity is 24-25%. It can be fed for 15 days at most, and the water needs to be changed once a week.

Scallop, scallop, mussel and snail: the water temperature is 0℃ and the salinity18-20%, which can be stored for up to 3 days. Generally, they are fed with running water. 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.

Mussel: 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. It 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 below10%, 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℃, salinity10-12%, which can be stored for 15 days at most, with water changed once every 5 days on average, and generally fed alone.

Live sea cucumber: water temperature 15℃ or so, salinity10-22%. 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.

Clam, snail, Meretrix meretrix and swan egg: water temperature 10℃ and salinity12%, which can be kept for up to 5 days. Generally, they are fed with running water, and these shellfish are generally not forbidden to be mixed, but they are kept alone because of their small size.

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.
