Good timing of autumn fish farming to help you increase efficiency

The change in water temperature in autumn is generally between 20 and 30°C, which is a good time for fish growth. In this time, 4 methods will increase your profit:

1. Fill the pond water. As the saying goes, "deep water raises big fish." The water level of the ponds cultured by adult fish is deep, and the water level of the fish breeding ponds can be added to 1.5 to 2 meters so that the fish can live in a good ecological environment with large space for activities, sufficient dissolved oxygen, and abundant natural food.

2. Put enough grass. Traditionally, aquaculture has a saying that “grass with three crops” means that sufficient forage can promote fecal water supply of grassy fish such as grasshoppers, cormorants, and oysters, and promote the growth of filter-feeding fish such as cockroaches and cockroaches. Generally every 100 kilograms of grass carp are fed with 20 to 30 kilograms of dry grass every day (or 80 to 100 kilograms of water plants, or 3 to 5 kilograms of fine material). In addition, we must look at the sky, see the water, watch the fish, and have a flexible grasp of the amount of fertilizers and fertilization. We must follow the principles of feeding and fertilizing that are less frequent, more diligent, and more diligent. Let the fish eat well.

3. Scientific management. In the fall, there is a saying that “one day is magnanimous” and fish ponds with more water quality should be guarded against flooding. In the sunny afternoon and late in the evening, turn on the aerator to increase oxygen, mix up the dissolved oxygen in the upper and lower water layers, and prevent nighttime hypoxia.

4. Prevent fish diseases. Adhere to the patrol pond every day to observe the eating and activities of the fish. Pay attention to changes in water quality, change new water frequently, generally change new water once a week, each time changing the water 10 to 15 centimeters. Fresh water should be kept fresh. Residues and baits should be removed promptly. The food table should be washed frequently. The table should be sterilized every two weeks or so using bleaching powder. Routine use of bleaching powder, copper sulphate, etc. should be regularly used to prevent fish disease. . Fish diseases and dead fish were found to be promptly removed for inspection and treated with drugs.
