What are the precautions for aquaculture in hot and humid weather?
Entering July, various regions will often experience hot, humid and rainy weather, which has brought adverse effects on the aquaculture industry in this region, so scientific management of aquaculture should be strengthened in a timely manner. Several technical key points are briefly introduced below:
Prevent stress: Continuous hot and humid weather, overcast days, plus rainy weather, can easily cause stress responses in aquatic products. It is recommended to add multivitamins to the feed to increase the body's adaptability.
Prevent oxygen deficiency: With no sunlight for consecutive days, a large number of beneficial algae in the water that can carry out photosynthesis to produce oxygen die off, rot and decompose, leading to oxygen deficiency in the water body, so artificial aeration is needed to maintain the normal growth of aquatic products. In addition, bait feeding should also be adjusted in a timely manner.
Prevent diseases: Hot and humid weather easily breeds bacteria, and parasites also multiply in large numbers, so prevention and treatment should be combined, using some lower-irritation insecticides and disinfectants to reduce the discomfort of aquatic products to drugs.
Frequent bottom improvement: Frequently use bottom-improving products; especially biological bottom improvers can effectively improve the substrate and prevent oxygen deficiency in the bottom layer caused by substrate deterioration.
Emphasize water regulation: First detoxify, then use microbial agents, especially EM bacteria, to spray the whole pond, which can quickly stabilize the bacterial phase and algal phase of the aquaculture water body and keep the water quality fresh and lively.
