Advantages of Puffed Floating Fish Feed
Advantages of Puffed Floating Fish Feed
1. Easy feeding and management to reduce diseases
Extruded aquatic feed can be suspended on the water surface for a long time. There is no need to set up a special feeding platform when feeding, just feeding at a fixed point. Fish need to float on the water surface when feeding, so they can directly observe the feeding situation of the fish, adjust the feeding amount in time, and understand the growth and health status of the fish in a timely manner. Therefore, the use of aquatic extruded feed is helpful for scientific feeding management, which not only saves a lot of time, but also improves labor productivity.
Breeders can calculate the amount of feed to be fed based on the species, specifications, quantity, water temperature and feeding rate of the fish being farmed, and feed the fish 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, neutrophilic bacteria, Escherichia coli, molds, salmonella, etc., and the content of animal feed raw materials is relatively high. The high temperature, high humidity and high pressure of puffing can kill most harmful microorganisms.
Data show that the number of E. coli in each gram of raw material reaches 10,000, and less than 10 remain after puffing. Salmonella can basically be killed after puffing at temperatures above 85°C, which helps maintain water quality and reduce aquatic products. The unfavorable environmental factors for 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 the feed.
2. Expanded floating fish feed improves feed utilization
Due to high-temperature and high-pressure processing conditions, the starch in the feed matures, and fats and other substances are more easily digested and absorbed, and the fiber structure and cell wall are destroyed and softened, and harmful substances such as gossypol in cottonseed meal and antitrypsin in soybeans are destroyed. , thereby improving the palatability and digestion and absorption rate of the feed.
In addition, due to the physical and chemical changes in the puffing process, the amount of powder produced in puffed feed is generally within 1%, which directly improves the effective utilization of feed. Under normal circumstances, using extruded floating feed to raise fish can save 5-10% of feed compared with using powdered feed or other pellet feed.
3. Advantages of expanded aquatic feed
Using extruded floating fish feed can reduce pollution to water quality. Puffed floating fish feed will not dissolve in water for a long time. The floating time of high-quality floating fish feed can be as long as about 12 hours, at least 6 hours. It is easy to observe and control when feeding, reducing or avoiding powder. , remaining residual bait and other pollution to the water body, which is extremely beneficial to environmental protection and the growth of fish.
In terms of farming methods, extruded floating fish feed has wide applicability. Floating fish feed can be used in pond fish farming, rice field fish farming, running water fish farming, cage fish farming, factory fish farming, and large water surface intensive farming. . Especially for fish farming in mountain ponds, rice fields and large water surfaces with low breeding density, using floating fish feed has more advantages than using other feeds.
In terms of cultured species, whether they are freshwater fish or seawater fish, except for a few bottom-dwelling fish that are extremely difficult to domesticate to feed on the surface, they can well eat floating fish feed, such as bass, snakehead, ornamental fish, and frogs. , soft-shell turtle, turtle, catfish and other famous and premium species as well as conventionally cultured grass carp, carp, crucian carp and other species. For frogs, bass and other species with special physiological functions, it is more convenient and more advantageous to use floating feed for breeding.
