Requirements for raising lobster fry:
After 7 ~10 days, the seedlings can be released after being disinfected with lime water, which requires high water temperature. The suitable growth water temperature is 20℃ ~ 30℃, and it is rarely eaten when it is lower than 15℃. The water body should maintain high dissolved oxygen, and the dissolved oxygen should be above 50 mg. The transparency of water body should be 30 ~ 40 cm. The pH value is 7.0 ~ 8.5. The shrimp fry with a density of1.5 ~ 3.5cm are stocked, and the stocking density is 4000 ~ 7000 fish/mu. When releasing the seedlings, put the plastic bag containing the shrimp seedlings in the pond for 30 minutes before opening it, so that the shrimp seedlings can gradually adapt to the water temperature in the pond, which is beneficial to improving the survival rate of the shrimp seedlings.
Extended data:
The feeding habits of lobsters are very diverse. All kinds of fresh aquatic plants, benthos, shellfish, molluscs, macrozooplankton, and the carcasses of various fish and shrimps and similar carcasses are all favorite food for lobsters, and they are also very fond of artificially fed feed. In the peak season, there are a lot of phytoplankton on the water surface downwind of the pond. It can be observed that the lobster puts its mouthparts on the horizontal plane and paddles the water with two big claws to send the algae on the water surface into its mouth, which shows that crayfish can even use the algae in the water.
