Why do fish farming need to feed extruded floating fish feed


01. Characteristics of extruded floating fish feed

Convenient feeding and management

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 on the surface of the water when ingesting, and can directly observe the fish’s eating situation, adjust the feeding amount 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.

Reduce the occurrence of diseases

Feed ingredients often contain harmful microorganisms, such as aerobic organisms, neutrophils, E. coli, molds, salmonella, etc. The content of animal feed ingredients is relatively high. The high temperature, high humidity, and high pressure of puffing can kill most harmful microorganisms.

According to data, the number of Escherichia coli per gram of raw material reaches 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 aquatic production. The unfavorable environmental factors of breeding can reach 0.4 at the same time, which is equivalent to a moisture content of 8%-10%, which better improves the storage stability of feed.
02. Comparison between the utilization rate of puffed and floating puffed materials and 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, the use of extruded floating feed to raise fish can save 5-10% of feed compared with powdered feed or other pellet feeds.
03. The influence of expanded floating material 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, at least 6 hours of floating time, and it is easy to observe and control the bait to reduce or avoid the powder. Remaining bait and other pollution to the water body, which is extremely beneficial to environmental protection and the growth of fish.
04. Prospects of Expanded Floating Material

The 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 farming, rice field fish farming, flowing water fish farming, cage fish farming, factory fish farming, and large water-intensive farming. . 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 breeding species, both freshwater and marine fish, except for a few bottom-dwelling fish that are extremely difficult to be domesticated to eat on the surface, they can well eat floating fish feed, such as perch, snakehead, ornamental fish, and frog. , Soft-shelled turtles, tortoises, catfish, and other famous and special varieties, 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.
Lima cooperates with world-famous enterprises and research institutes, combining advanced Europe technology with years of practical experience, we have successfully developed 12 series of fish feed pellet machines with advanced technology and reliable performance. In the manufacturing process, we adopt integrated quality control and have passed ISO9001 international authentication. We adopt a world-famous brand for the key electronic elements, pneumatic and hydraulic system to ensure high quality and reliability of the poultry fish feed pellet machine.
