In order to ensure the healthy growth of aquatic products and the degree of safety in summer, according to the current climate and production characteristics, the relevant experts of the Provincial Aquatic Technology Extension General Station and the provincial aquatic products industry technical system put forward the following recommendations for reference by farmers.
Deepen the water level. Strengthen water quality monitoring, pay close attention to changes in water quality, and maintain the best breeding water level. Pond water quality was measured once every 5 to 7 days, maintaining a water clarity of 30 to 35 cm and a pH of 7.0 to 8.5. Sufficient ponds should be filled with water every 3 to 5 days. Add water for the morning or evening. Add 10 to 20 cm each time.
Conservation of aquatic plants. For crab breeding ponds, we must strictly control the total amount and density of aquatic plants, and play the best role of aquatic plants. Excessive water plants have a large purification effect, but perishable water quality conflicts. Over 60% of the water in Tongkou is covered by weeds, and part of the aquatic weeds are removed in time with dragging cutters to remove the ponds and open the “well†channel to make the grasses dense and reasonable and grow vigorously, leaving some space for the free activities of the crabs. For early crab grass ponds that are severely damaged, prompt remedial measures should be taken. Water hyacinths, water peanuts, and leeks must be properly transferred. With the increase of water temperature, Elodea in Crab Pond appears "crazy" phenomenon, which is likely to cause lack of oxygen in crab ponds and large area of ​​grasses to destroy water quality. It is necessary to manually remove some Elodea. In order to protect aquatic plants, feed in intensive ponds should be scattered as far as possible. Regular use of Bacillus prevents excessive accumulation of dirt on aquatic plants.
Reasonable feeding. Continuous high-temperature exposure, fish, shrimp, crab appetite decreased, feeding should be reduced to less than 70% of the calculation, can be properly added VC, immune polysaccharides and lactic acid bacteria powder and other health products to protect the liver and intestinal health, promote digestion and absorption, improve Aquatic animal immunity. On sunny days, noon ponds were opened for 2 to 3 hours. At 10:00 in the evening, they were turned on until the morning. They were turned on hot and rainy days. Shrimp and crab ponds control aquatic weeds to cover no more than 60%. When they exceed the time, they should remove part of the plants and expose Elodea. The grass should be cut off to control its growth at 30 cm below the water surface. Replace pool water properly and open microporous aerator at night. Strengthen the patrol inspection, observe carefully the activities of aquaculture animals and the changes in water quality, and if any are abnormal, take timely measures to improve them.
Use drugs rationally. In the summer high temperature season, the water environment changes rapidly, and microorganisms reproduce rapidly and have many diseases. Many farmers will use disinfectants, algaecides, roticides, and sediment modifiers to prevent disease and regulate water quality and sediment quality. At this time, the application of topical drugs should be reduced as appropriate, because the higher the water temperature, the greater the toxicity of the drug, the greater the risk of medication, after the start of the aerator to stir the water, to break the thermal layer, to avoid the high concentration of drugs caused by local water Animal damage. In summer, many pond culture aquaculture animals are in the state of “drifting head†and “floating headâ€. In addition to oxygenating agents, the use of any other medicine will stimulate the farmed animals and special attention should be paid. After changing the water in shrimp and crab ponds, it usually induces shelling of shrimps and crabs. At this time, it is not appropriate to use drugs. In particular, the higher the water temperature, the more toxic the drugs such as copper sulfate should be used with caution.
