Time and method of juvenile crab release

When young crabs are released, they should be caught in crabs and the crab ponds can be completely cleaned and disinfected. The juvenile crabs are predominantly in winter and can be roughly from December of the current year to the end of February of the second year. Juvenile crabs should be put in sooner rather than later. Appropriate early release can adapt the young crabs to adapt to the pond's environmental conditions, extend the growing period accordingly, and increase the size of crabs listed on the market. Long-distance transport of juvenile crabs requires a long time to leave the water. Do not immediately put them into the pond after reaching the ponds to be put in. Soak them in the water for a few minutes together with the packing tools. Put the water on the surface for 5-10 minutes before putting it into the water again. Soak for a few minutes so that the juvenile crabs repeatedly absorb water, then open the package and put it into the lower pool. It is advisable to allow young crabs to climb into the pond on their own, so that it is easy to observe the juvenile constitution and determine the disability and death. It should be in the morning or evening. Juvenile crabs also use 3% - 4% saline or 50% mg/kg potassium permanganate solution before soaking for 3 - 5 minutes to prevent crab disease. Putting some species of fish, such as squid and squid, in the ponds where crabs are raised helps to purify the water, reduce the number of water changes, or change the amount of water, and can also make full use of water resources. The size of the fingerlings is suitable for 40-50 grams of tail weight. Generally, 100-150 tails of squid and 50-60 tails of squid can be released per acre. Without feeding feed and fertilizer, fish can reach 500-750 grams by the end of the year, yielding an increase of 100 kilograms per mu.
