Analyze the characteristics and advantages of extruded floating fish feed:
1. Features of extruded floating fish feed
Feeding management is convenient, the aquatic extruded feed can be suspended on the water surface for a long time,
and there is no need to set up a feeding table when feeding, only fixed-point feeding is enough. Fish need to float up
to the surface of the water when they eat, so they can directly observe the fish's eating situation, adjust the feeding am
ount in time, and understand the growth and health of the fish in time. Therefore, the use of aquatic extruded feed is
helpful for scientific feeding and management, which not only saves a lot of time, but also improves labor productivity.
Breeders can calculate the amount of bait that should be fed according to the species, specifications, quantity, water
temperature and bait rate of the fish being cultured, and feed them quickly, which not only saves a lot of time, but also
improves labor productivity.
To reduce the occurrence of diseases, feed materials often contain harmful microorganisms, such as aerobic organisms, neutrophils, Escherichia coli, molds, and salmonella. The content of animal feed materials is relatively high. The high temperature, high humidity, and high pressure of the expansion can kill most harmful microorganisms. According to data, the number of Escherichia coli per gram of raw material is up to 10,000, and there are only less than 10 remaining after expansion. Salmonella can basically be killed after being expanded at a high temperature above 85 ℃, which helps to maintain water quality and reduce The unfavorable environmental factors of aquaculture reach 0.4 at the same time, which is equivalent to a moisture content of 8%-10%, which can better improve the storage stability of feed.
2. Comparison of the utilization rate of puffed and floating puffed feed with powdered materials and granular
materials
Extruded floating fish feed is beneficial to improve feed utilization. Due to the high temperature and high pressure processing
conditions, the starch in the feed is matured, fat, etc. are more conducive to digestion and absorption, and the fiber structure
and cell wall are destroyed and softened, and the gossypol in cottonseed meal and the antitrypsin in soybeans and other
harmful substances are destroyed , Thereby improving the palatability and digestibility of the feed.
In addition, due to the physical and chemical changes in the extruded process, the extruded feed generally produces powder
within 1%, which directly improves the effective utilization of the feed. Under normal circumstances, using extruded floating
feed to raise fish can save 5-10% of feed compared with powdered feed or other pellet feeds.
3. The impact of expanded floating feed on water quality
The use of extruded floating fish feed can reduce water pollution. The extruded floating fish feed will not dissolve in the
water for a long time. The floating time of high-quality floating fish feed can be as long as 12 hours, and it is easy to observe
and control on the bait to reduce or avoid the influence of powder and residual bait on the water. The pollution, which is
extremely beneficial to environmental protection and the growth of fish.
4. Prospects of expanded floating fish feed
Extruded floating fish feed has a wide range of application prospects. In terms of breeding methods, extruded floating
fish feeds have wide applicability. Floating fish feeds can be used for pond fish culture, rice field fish culture, flowing water
fish culture, net cage fish culture, factory fish culture, and large water intensive culture. . Especially for fish farming in
mountain ponds, rice field fish farming and large water surface intensive farming where the farming density is low, the use
of floating fish feed is more advantageous than other feeds.
In terms of cultured species, both freshwater and marine fish, except for a few bottom-dwelling fish that are extremely
difficult to be domesticated and eat on the surface, they can well eat floating fish feed, such as perch, snakehead, watch fish,
etc. Famous frogs, soft-shelled turtles, tortoises, catfish, etc., as well as conventionally farmed grass carp, carp, crucian carp
and other varieties. For the American frogs, sea bass and other species with special physiological functions, it is more
convenient to breed with floating feed, and it can show its superiority.
According to different species and different growth and development stages, the production of extruded and floating
fish feeds that are compatible with their calibers and nutritional needs can well meet the needs of conventional aquaculture
and special aquaculture for their feed, which is convenient for farmers, It can also promote the development of production.
