August is the most critical period for crab farming. At this time, the temperature is high, the weather changes frequently, and a large number of microorganisms in the water are breeding. This severely damages the aquaculture water environment and can easily cause crab disease. August crab breeding technical guidance points are as follows: 1. Water level regulation August water level should be adjusted to maintain the highest water level, to maintain a depth of 1.2 meters, to maintain the water grass cover rate of 50% -60%, every 1 day - 2 days to the pond water, stable pond level. 2. Water quality regulation Water quality regulation should be strengthened. Change water frequently. Change water every 30 centimeters. In the high-temperature period, inject water every other day for 1 to 2 days. Use biologics every 7 days to 10 days to regulate water quality and maintain good water quality. 3. The food science feeds should adjust the ratio of vegetal to animal sex appropriately. The amount of feeding should be 7%-8% of the body weight of crabs. The proportion of vegetative food before the shell should be increased accordingly, and the proportion of animal food after oyster shells should be increased accordingly. Adopt four principles and four principles for science. 4. Disease Prevention and Control The main prevention measures are prevention and control, and the principle of prevention and control is combined. Generally, lime is splashed and sterilized once every 10 days and 15 days. The prevention and treatment of the disease should be strengthened. Do not blindly use drugs or abuse drugs. When using insecticides Be cautious. 5. Oxygen In the high-temperature period, oxygen-enhanced equipment should be turned on, and “granular oxygen†can also be spilled in the whole pool to keep sufficient oxygen in the pond, which is conducive to the normal growth of crabs. 6. Remove the residual baits, aquatic plants in the breeding, encounter floating and sedimentation of aquatic plants in a timely manner to remove, so as not to cause water quality deterioration, when the water plants are scarce, timely replanting plants. The residual bait is often removed and the food premises are sterilized.
