All kinds of seafood culture methods, water temperature control is very important.

Lobster: the water quality with no pollution and rich dissolved oxygen should be selected, at the same time, the water temperature should be about 20 ℃, the salinity should be about 25 °, the stocking time of shrimp seedlings should be spring and autumn, and the food should be disinfected by soaking in salt water before stocking. Grouper: very sensitive to temperature, suitable for growth temperature of 25-30 ℃, salinity of about 25 °, all grouper can be mixed culture. Shellfish: can be raised in dry or water, as long as the temperature is controlled at about 0 ℃.

Lobster

1. Water quality requirements

Lobster is very adaptable, in the process of breeding, it is best to choose relatively pollution-free water quality, at the same time, the dissolved oxygen in the water must be rich, if the water is not muddy, you can change the water once every three months. For the water temperature, the water temperature should not be too low. It is best to maintain the water temperature at about 20 ℃, and the salinity is about 25 °.

2. Pond disinfection and fertilization

Pond disinfection is mainly sprinkled with quicklime on the pond, quicklime can play a role in disinfection, can remove harmful substances, but also can reduce pathogens and parasites. Applying an appropriate amount of fertilizer to the pond can cultivate microorganisms and plankton in the pond, so that the lobster can eat freely. However, it is not suitable to apply too much fertilizer, and the fertilizer needs to be determined according to the area of the pond.

3. Shrimp fry restocking

Shrimp fry stocking time can choose spring and autumn, it is best to choose similar size shrimp fry in one time. Shrimp seedlings need to be soaked in salt water before stocking, which can eliminate some of the parasites and germs that they carry.

4. Management

Planting the right amount of aquatic plants in the pond can increase the dissolved oxygen in the pond, lower the water temperature in hot summer weather, and provide a place for lobster to rest and shade. However, when planting aquatic plants, do not plant too large areas, it is best not to exceed 1/2 of the area of the pond.

Lobster can choose broken-shell snail meat, mussel meat and animal offal when feeding, the food needs to be matched with meat and meat, not too simple, and meat can be mixed with plant feed such as wheat and corn. the feeding times depend on its growth and weather, usually 2-3 times a day.

II. Spotted fish

1. Grouper includes grouper, eastern grouper, mouse grouper and so on. Grouper is very sensitive to temperature, so it is necessary to control the water temperature in winter, and the suitable temperature for growth is about 25-30 ℃.

2. It is also required that the water quality should be pollution-free and transparent, and the water should be changed frequently, and the concentration of salt water should be maintained at about 25 °.

3, pond culture, it is best to imitate the sea area, the bottom quality of sand or sand is better, the pond water should reach more than 1 meter.

Third, shellfish

Shellfish include scallops, green mouths, scallops and snails, and so on. They all belong to species that prefer cold water temperatures. Shellfish can adapt to two culture methods, namely dry culture and water culture, both of which need to control the temperature at about 0 ℃.

If you keep it dry, you need to wrap the crushed ice together with shellfish, and then store it with ice at any time at 0 ℃.

If the water is raised, it is better to be flowing water, and the concentration of salt water should be controlled at about 20 °.
