1, herring culture in the culture area, we should choose a suitable culture area, there should be enough water around the pond, and the water quality should reach a certain standard, so as to facilitate the drainage work of the fish pond. In addition, traffic should be more convenient to manage the pond.

2. cleaning the pond before aquaculture, we must clean the whole pond thoroughly. First, we need to pump the water out of the pond. Remove some silt from the bottom of the pond and then water it. After that, we can't put the fry too fast. We should disinfect the river first, cultivate the water quality with some drugs, and measure the pH value in the water to ensure that the environment and various conditions in our water can meet the growth needs of herring. Herring culture technology.

3. When buying fry, you must choose those with strong physique and similar specifications. Only in this way can fish be produced in batches, and the physical condition will not be much different, so as to ensure that we will not have many bad conditions in the later breeding process. After the fry are purchased, they must be disinfected with some corresponding drugs. When releasing the fry, we try to choose a warmer weather, and we don't need to put other bait for a day or two after releasing the fry.

4. In the late stage of feed feeding, we must pay attention to the fixed position and time of each feeding, which will help the fish develop good eating habits. For feed treatment, we must ensure that it is excellent, there can be no mildew and deterioration, and the protein in the feed can not exceed 25%. The feeding times are different in different seasons, and the energy consumption of fish is large in summer. In autumn, it can be appropriately reduced to four times a day, and the feeding amount should not be too large each time. In any case, the feed we feed must be eaten within three hours, and there can be no waste.

5. Daily management of rainy weather may cause insufficient support in the pond. At this time, the aeration equipment can be turned on to provide sufficient oxygen for the fish. Especially when the fry enter the medium-term rapid growth stage, it is necessary to maintain quantitative aeration every day, change the water source regularly, and replenish some water to the pond in summer, especially to increase the quality of water change when the water quality becomes worse.
