Features of extruded floating fish feed

1. Convenient feeding management

Aquatic extruded 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 need to float on the surface of the water 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.

To reduce the occurrence of diseases, feed raw materials often contain harmful microorganisms, such as aerobic organisms, neutrophils, Escherichia coli, mold, salmonella, etc., and the content of animal feed raw materials is relatively large. The high temperature, high humidity and high pressure of puffing can kill most of the harmful microorganisms. According to data, the number of E. coli per gram of raw material reaches 10,000, and less than 10 remain after puffing. Salmonella can basically be killed after puffing at a high temperature above 85 ℃, which helps to maintain water quality and reduce Unfavorable environmental factors for aquaculture, while reaching 0.4, which is equivalent to a moisture content of 8% -10%, better improve the storage stability of diced feed.

2. The influence of expanded floating material on water quality

The use of extruded floating fish feed can reduce the pollution of water quality. 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.

Comparison of utilization rate of puffed buoyant puffed material with powdered material and granular material

Extruded floating fish feed is beneficial to improve feed utilization. Due to the processing conditions of high temperature and high pressure, the starch in the feed is ripened, fat, etc. are more conducive to digestion and absorption, and the fiber structure and cell wall are destroyed and softened, and harmful substances such as gossypol in cottonseed meal and antitrypsin in soybean are destroyed , thus improving the palatability and digestion and absorption rate of the feed.

In addition, due to the physical and chemical changes of the extruded feed, the extruded feed generally produces powder within 1%, which directly improves the effective utilization of the feed. Under normal circumstances, fish farming with extruded floating feed can save 5-10% of feed compared with powder feed or other pellet feed.

Prospects of expanded floating materials

The extruded floating fish feed has wide application prospects. In terms of breeding methods, extruded floating fish feed has a wide range of applicability, and can be used for 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 feed well on floating fish feed, such as perch, snakehead, ornamental fish, Famous and high-quality species such as American frog, soft-shelled turtle, turtle, and fork-tailed catfish, as well as conventionally farmed grass carp, carp, and crucian carp. For frogs, perch and other species with special physiological functions, it is more convenient to use floating feed for breeding, and it can show its superiority.

According to different species and different growth and development stages, extruded floating fish feeds suitable for their caliber and nutritional needs can be produced, which can well meet the needs of conventional aquaculture and special aquaculture for their feed, which is convenient for aquaculture producers. It can also promote the development of production.
