First, the storage time should not be too long
The pellet feed contains 12% to 14% of water in the production process, and has a long storage time, and is easily deliquescence and mildew, which affects the use value of pellet feed. After feeding, fish is susceptible to disease. It is best to produce while feeding.
Second, increase the number of feeding
The fish has no stomach, and the feed has a short residence time in the intestine. The utilization rate is not high. Therefore, under the condition that the total amount of bait is not changed, the number of feedings should be increased and the amount of each feeding should be reduced, so that the fish can always be in a state of semi-starvation, which can increase the utilization of food and reduce the feed coefficient.
Third, there must be a certain bait area and time
In multi-variety polyculture ponds, squid and grass carp catch food fast and eat a large amount, while squid eats “Swen†and the corresponding food intake is small, which often affects its growth. Therefore, the use of pellet feed should be carried out for a short period of domestication, so that the fish form a fixed food market, a fixed time of feeding habits, each feeding should be uniformly distributed, feeding time is not less than 30 minutes, feeding area of ​​40 square meters ~ 60 square meters, so that each fish can feed food.
Fourth, the particle size should be reasonable
When the fish species are stocked, the water temperature is low, the growth is slow, and the size is small. The particle feed is controlled at a size of 2 mm. With the temperature rising and the species growing, the mid-aquaculture feed has a particle size of 3 mm to 3.5 mm. It is 4 mm to 4.5 mm.
Fifth, add salt to prevent fish disease
In the production of feed pellets, 1% salt is evenly mixed in the raw materials to sterilize and prevent fish diseases.
Sixth, to apply fertilizer
The pellet feed loses in the water and the fish has a high utilization rate, which can increase the growth rate of eating fish. However, because the quality of the water in the pool is relatively light, the feeding effect of the fertilized fish is not very good. Therefore, the fish pond fed with the pellet feed must be reasonably fertilized, promote the growth and reproduction of plankton, and increase the aquaculture production of the fertilized fish.
