Spring fish farming, water transfer spring first spring flowers, water temperature began to rise, plankton began to reproduce, is a good season for water and fertilizer. First, fertilizer, water, algae, regulate water quality. One of the best means to improve the aquaculture animal's constitution is to fertilize algae and provide a material basis for feeding. The method is to apply 500 g of gold F baby microbial fertilizer per acre, and the water color can be turned green two days later to cultivate a large number of food organisms suitable for aquatic animals. At the same time, the fertilizer can also regulate water quality, increase dissolved oxygen in water, degrade the accumulated organic matter in the pond over long-term wintering, and remove harmful substances such as ammonia and hydrogen sulfide to improve water quality. Second, "a small amount of time, less Shi Qin Shi." After the aquaculture pond has good water and water quality, it should be maintained. Especially after the floods and floods, the weather in spring is particularly unstable, and more attention should be paid to the regulation of water color and water quality. Should follow the "a small number of times, less Shi Qin Shi" principle of the use of gold F baby microbial fertilizer, it is recommended to apply twice a month, each application of 500 grams per acre, according to the color and fish conditions increase or decrease as appropriate.
