First, when the crabs were released, the crabs began to be stocked. Because the crabs were not adapted to the new water environment, they all crawled around the pool and often caused a large number of crabs to escape. Anti-escape measures may be preceded by 1 mu to 2 mu of water surface in the crab pond, which will be raised for a short period of time. After the crab species adapts to the new water body, it will be reared to the crab pond.
Second, when there is a serious lack of bait in the crab pond, when the natural food and artificial bait in the crab pond are seriously lacking, on the one hand it will cause the crabs to kill each other; on the other hand, the crab will escape due to the bait. Anti-escape measures Spring crab ponds put 200 kilograms of fresh snails per acre, allowing them to breed naturally and allow crabs to feed freely. During the growing season, feeding should be strengthened. Feeding should be done twice a day. The amount of feeding should be 5% to 10% of the amount of pool crabs. The bait is dominated by animal foods, supplemented by plant foods.
The third is when the weather suddenly changes, especially when there are severe weather such as wind and rain. Anti-escape measures to deepen the water level when the weather changes, and then restore the original water level after the rain.
Fourth, when the ecological conditions are poor, such as small pond grasses, low transparency and low dissolved oxygen, etc., it is not conducive to shelling growth of crabs, crabs will seek a suitable environment to escape. Anti-escape measures 1. Crab ponds to keep enough water, the stability rate is stable at more than 50%; 2. The growth season every 2 days to 4 days for a new water, splash lime once every 15 days, so that the pool of dissolved oxygen to maintain at 4 mg Above 1 liter, the pH is 7.5 to 8 and the transparency is 30 cm to 40 cm.
The fifth is that when the gonadal gonadal develops and matures when migrating in river crabs, it is necessary to carry out reproductive migration. In particular, when the northwest winds or heavy rains are scraped before and after the frost falls, the crabs frequently move and climb along the pool walls. Anti-escape measures 1. Reinforce anti-escape facilities; 2. Promptly catch ripe crabs.
