How to cryopreserve flying crabs, and how to preserve flying crabs that have just died?

Flying crabs. Storage: refrigerators, temporary storage pools.

1. Store flying crabs in the refrigerator.

For the cryopreservation of crabs, we have to depend on the situation, for example, the cryopreservation of live crabs and the cryopreservation of dead crabs are not the same. So, can flying crabs be frozen? Can flying crabs be frozen?

The crab king hand Sakura Palace hairy crab base will pay attention to the cultivation of aquatic plants in the breeding area, and adopt a recuperation policy in the release of hairy crab seedlings and the density of aquatic plants. Crab fingerlings are first stocked in the temporary breeding area where aquatic weeds have grown to a certain height and density, and are scattered at multiple points. When the aquatic weed coverage in other areas reaches 50% to 70%, the hairy crab breeding area will be enlarged.

For hairy crabs, aquatic plants determine whether the multiple shelling of hairy crabs can be successfully completed during the growth process, whether the oxygen content in the water is sufficient, and whether the natural food that hairy crabs rely on for survival is diverse. These factors, which play an important role in the growth of hairy crabs, can grow high-quality hairy crabs in this area if they are naturally provided by nature and suitable for the growth of hairy crabs.
