After the flood season, local aquaculture farmers should promptly renovate production facilities such as ponds, purse seine, and machinery. In the management of aquaculture, do the following: First, scientific feeding. From July to September, the water temperature is still relatively high, which is a critical period for the growth of fish, shrimp, crabs, and it is necessary to select high-quality feeds for scientific feeding according to their feeding characteristics. Routine fish should be fed with full-priced compound feed; in addition to feeding fine-grained feed, green shrimp should also be properly fertilized bait; crabs should be properly matched with quail, sperm and green feed. In accordance with the requirements of the "Four Ding" (timing, qualitative, positioning, quantitative) principle, but the daily feeding amount should be based on "four look" (see the weather, see the water quality, see the water temperature, see the fish shrimp and crab activities and feeding conditions ) The principle of increasing or decreasing as appropriate, to ensure that a variety of aquatic products to eat, eat well, healthy and rapid growth. The second is to regulate water quality. By using oxygen aerators and splashing oxygenating agents normally, the dissolved oxygen in the pool water must not be lower than 3 mg/L at any time. Regularly sprinkling biological agents such as photosynthetic bacteria and EM bacteria, and reforming formulations to improve the quality of pond bottoms and water, so as to keep the water quality “new, live, tender and coolâ€. Each aerobic machine is equipped with an aerator per 8-10 mu, and the aerator will be opened at noon and before dawn in the high-temperature season to ensure the normal growth of fish, shrimp and crabs. The third is to prevent diseases. The first is to observe the situation of feeding, growth, clam shells and activities of the aquaculture animals in the area through the patrol pond. The second is to select palatable and nutritious high-quality feed, determine the amount of feeding and the number of feeding according to the weather conditions, eating conditions, water environment and other factors, to ensure that aquatic animals are full, eat well, do not waste feed, do not cause environmental problems. Pollution, improve the self-immunity of farmed animals. The third is to adhere to the principle of prevention and comprehensive prevention and control, and take regular preventive measures for drugs so as to prevent problems before they occur. The fourth is timely sales. The conventional products such as C. oligorius and “Four Home Fish†began to be caught in the market from early July to late July; the shrimps can be caught in regular rounds of sales; Aphrodisiac, loach, stingray, black frog, turtle, etc. The special aquatic products such as bullfrogs should also be subject to round-robin and listing measures in light of market conditions and breeding density.
