1. Characteristics of puffed floating fish feed
A. Easy feeding and management
Puffed aquatic feed can be suspended on the water surface for a long time. There is no need to set up a feeding platform for feeding. It only needs to be fed at a fixed point. Fish need to float on the water surface when feeding, so that the fish's eating situation 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 puffed aquatic feed is helpful for scientific feeding management, which can save a lot of time and improve labor productivity.
Farmers can calculate the amount of feed to be fed according to the species, specifications, quantity, water temperature and feeding rate of the fish to be farmed, and feed quickly, which can save a lot of time and improve labor productivity.
B. Reduce the occurrence of diseases
Feed raw materials often contain harmful microorganisms, such as aerobic organisms, neutrophilic bacteria, Escherichia coli, mold, Salmonella, etc., and the content in animal feed raw materials is relatively high. The high temperature, high humidity and high pressure of puffing can kill most of the harmful microorganisms.
Data show that the number of E. coli in each gram of raw material is as high as 10,000, and only less than 10 remain after puffing. Salmonella can be basically killed after high-temperature puffing above 85 ℃, which helps to maintain water quality and reduce adverse environmental factors for aquaculture. At the same time, it reaches 0.4, which is equivalent to a moisture content of 8%-10%, which better improves the storage stability of feed.
2. Comparison of the utilization rate of puffed floating puffed feed with powdered feed and granular feed
Puffed floating fish feed is conducive to improving feed utilization. Due to high temperature and high pressure processing conditions, the starch in the feed is ripened, and the fat is more conducive to digestion and absorption, and the fiber structure and cell wall are destroyed and softened, and harmful substances such as cotton phenol 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 of puffing processing, the powder produced by puffed feed is generally less than 1%, which directly improves the effective utilization of feed. Under normal circumstances, using puffed floating feed to raise fish can save 5-10% of feed compared with using powdered feed or other granular feed.
3. The impact of puffed floating feed 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 it is easy to observe and control the feeding, reducing or avoiding the pollution of powdered feed, residual bait, etc. to the water body, which is extremely beneficial to environmental protection and fish growth.
4. The prospect of puffed floating feed
Puffed floating fish feed has a wide range of application prospects.
In terms of breeding methods, puffed floating fish feed has a wide range of applicability. Floating fish feed can be used in pond fish farming, rice field fish farming, flowing water fish farming, cage fish farming, factory fish farming, and large water surface intensive farming. Especially for fish farming in mountain ponds with low breeding density, fish farming in rice fields and intensive breeding on large water surfaces, floating fish feed has more advantages than other feeds.
In terms of breeding species, whether freshwater fish or marine fish, except for a few benthic fish that are extremely difficult to domesticate to feed on the water surface, they can all feed on floating fish feed very well, such as perch, black snakehead, ornamental fish, frog, turtle, forktail catfish and other famous and excellent species, as well as conventionally farmed grass carp, carp, crucian carp and other species. For species such as American frogs and perch with relatively special physiological functions, it is more convenient to breed them with floating feed, which can better show its superiority.
According to different species and different growth and development stages, our equipment can produce puffed floating fish feed that is suitable for their caliber and nutritional needs, which can well meet the feed needs of conventional breeding and special aquaculture.
