The control of pool color is the main technical measure for daily management. Good green color such as bean green and tea brown is a comprehensive indicator. It indicates that phytoplankton in pond water is a high-quality population of cryptophytes, diatoms and other algae. If these algae form blooms, it indicates that various nutrients are abundant. The metabolic intermediates decompose rapidly and the dissolved oxygen is in good condition. In order to make the water color good, it is necessary to fertilize and inject new water in a timely manner and discharge the pool water.
The bait is mainly water grass, dry grass and algae, supplemented with food, oil cakes, cereals and bran or snail, shellfish and so on. Feeding should be timely, appropriate, and fixed in order to check fish feeding conditions. The purpose of fertilization is to cultivate phytoplankton in ponds, mainly poultry, animal manure and green manure. In high-yield intensive intensive fish ponds, due to the high stocking density of fish, the amount of fertilizer used for feeding is high, and the amount of dissolved oxygen tends to drop, which threatens the survival of fish. New water or oxygen must be injected in time to avoid the occurrence of fish pans and floating heads.
