Extruded fish feed is an extruded porous feed obtained after the high temperature and high pressure of the extruder is suddenly reduced. Extruded feed can be used as fish feed, and the effect of extruded feed is better because of its good palatability and high digestibility.
The extruded floating fish feed has wide application prospects. In terms of breeding methods, extruded floating fish feed has wide applicability, and floating fish feed can be used in pond fish farming, rice field fish farming, running water fish farming, cage fish farming, industrial fish farming, and large water surface intensive farming. Especially for fish farming in Shanping ponds with low breeding density, fish farming in paddy fields, and intensive farming on large water surfaces, the use of floating fish feed has more advantages than other feeds. In terms of cultured species, whether it is freshwater fish or seawater fish, except for a few bottom-dwelling fish that are extremely difficult to domesticate to feed on the water surface, they can all eat floating fish feed well.
The puffed floating fish feed can be suspended on the water surface for a long time, and there is no need to set up a special feeding platform when feeding, and only need to feed at fixed points. The fish needs to float on the water surface when feeding, so that the feeding situation of the fish can be directly observed, the feeding amount can be adjusted in time, and the growth and health status of the fish can be understood in time. Therefore, the use of aquatic extruded feed is conducive to scientific feeding management, which not only saves a lot of time, but also improves labor productivity. Farmers can calculate the amount of bait to be fed according to the species, specifications, quantity, water temperature and bait feeding rate of the fish being farmed, and feed them quickly, which not only saves a lot of time, but also improves labor productivity.
The use of extruded floating fish feed can reduce water pollution. The puffed floating fish feed will not dissolve in the water for a long time, and the high-quality floating fish feed can float for about 12 hours, and it is easy to observe and control the feeding, so as to reduce or avoid the impact of powder and residual bait on the water body. pollution, which is extremely beneficial to environmental protection and the growth of fish.
