Why is it necessary to feed puffed floating fish feed in fish farming?

Aquatic puffed feed can remain suspended on the water surface for a long time, and there is no need to set up a dedicated feeding platform for feeding. It only needs to be fed at a fixed point. Fish need to float on the surface of the water when feeding, and can directly observe the feeding situation of fish, adjust the feeding amount in a timely manner, and understand the growth and health status of fish in a timely manner. Therefore, using aquatic puffed feed can help with scientific feeding management, saving a lot of time and improving labor productivity.

Aquaculture personnel can calculate the amount of bait to be fed based on the variety, specifications, quantity, water temperature, and feeding rate of the fish being farmed, and feed quickly, which not only saves a lot of time but also improves labor productivity.

Feed raw materials often contain harmful microorganisms, such as aerobic organisms, neutrophils, Escherichia coli, fungi, Salmonella, etc. The content of animal feed raw materials is relatively high. The high temperature, high humidity, and high pressure of puffing can kill the vast majority of harmful microorganisms.

Due to the high temperature and high pressure processing conditions, the starch in the feed is matured, the fat is more conducive to digestion and absorption, and the fiber structure and cell wall are destroyed and softened. Harmful substances such as gossypol in cottonseed meal and anti trypsin in soybean are also destroyed, thereby improving the palatability and digestion and absorption rate of the feed.

In addition, due to the physical and chemical changes in puffing processing, puffing feed generally produces less than 1% powder, which directly improves the effective utilization of feed. Under normal circumstances, using puffed floating feed for fish farming can save 5-10% of feed compared to using powdered or other granular feed.

The impact of puffed floating materials on water quality

Using puffed floating fish feed can reduce water pollution. Puffed floating fish feed will not dissolve in water for a long time. High quality floating fish feed can float for up to 12 hours, at least 6 hours, and is easy to observe and control during feeding, reducing or avoiding pollution to the water body from powder, residual bait, etc. This is extremely beneficial for environmental protection and fish growth.

The prospect of puffed floating materials

Puffed floating fish feed has a wide range of application prospects.

In terms of aquaculture methods, puffed floating fish feed has a wide range of applicability. Floating fish feed can be used for pond fish farming, rice field fish farming, flowing fish farming, cage fish farming, factory fish farming, and large-scale intensive aquaculture. Especially for fish farming in mountain ponds with low breeding density, fish farming in rice paddies, and intensive aquaculture on large water surfaces, using floating fish feed has more advantages than using other feeds.

In terms of aquaculture species, both freshwater and saltwater fish can feed well on floating fish feed, except for a few benthic fish that are extremely difficult to domesticate to the surface, such as sea bass, snakehead, ornamental fish, frogs, soft shelled turtles, turtles, channel catfish and other famous and excellent species, as well as commonly farmed grass carp, carp, crucian carp and other species. For species with special physiological functions such as American frogs and sea bass, using floating feed for breeding is more convenient and can better demonstrate their superiority.

According to different varieties and growth stages, producing puffed floating fish feed that is suitable for their caliber and nutritional needs can well meet the feed needs of conventional aquaculture and special aquaculture, which not only facilitates aquaculture producers but also promotes production development.
