The advantages of puffed floating fish feed
According to different varieties and growth stages, producing puffed floating fish feed that is suitable for their caliber and nutritional needs can well meet the feed needs of conventional aquaculture and special aquaculture, which not only facilitates aquaculture producers but also promotes production development.
Convenient feeding and management to reduce diseases
Aquatic puffed feed can be suspended on the water surface for a long time, and there is no need for a dedicated feeding platform during feeding. It only needs to be fed at a designated location. When fish feed, they need to float on the water surface, be able to directly observe the feeding situation of the fish, adjust the feeding amount in a timely manner, and understand the growth and health status of the fish in a timely manner. Therefore, using aquatic puffed feed helps with scientific feeding management, saving a lot of time and improving labor productivity.
Breeding personnel can calculate the amount of bait to be fed based on the variety, specifications, quantity, water temperature, and feeding rate of the fish being farmed, and feed them 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, fungi, Salmonella, etc. Animal feed raw materials have a relatively high content. The high temperature, high humidity, and high pressure of expansion can kill the vast majority of harmful microorganisms.
According to data, the number of Escherichia coli in each gram of raw material reaches 10000, with less than 10 remaining after expansion. Salmonella can be basically killed after high temperature expansion above 85 ℃, which helps to maintain water quality and reduce adverse environmental factors in aquaculture, while achieving 0 4. This is equivalent to a moisture content of 8% -10%, which better improves the storage stability of the feed.
Expanding Floating Fish Feed to Improve Feed Utilization
Due to the processing conditions of high temperature and high pressure, starch in the feed is matured, fat and other substances are more conducive to digestion and absorption, and the fiber structure and cell wall are damaged and softened. Harmful substances such as gossypol in cottonseed meal and anti trypsin in soybean are also destroyed, thereby improving the palatability and digestion and absorption rate of the feed.
In addition, due to the physical and chemical changes in puffing processing, puffed feed generally produces powder within 1%, which directly improves the effective utilization of feed. Under normal circumstances, using puffed floating feed for fish farming can save 5-10% of feed compared to using powdered or other pellet feed.
The advantages of puffed aquatic feed
The use of puffed floating fish feed can reduce water pollution. Expanded 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 is easy to observe and control during feeding, reducing or avoiding pollution of water by powder and residual bait. This is extremely beneficial for environmental protection and fish growth.
In terms of aquaculture methods, puffed floating fish feed has a wide range of applicability. Floating fish feed can be used for pond fish farming, rice field fish farming, flowing water fish farming, net cage fish farming, factory fish farming, and large-scale surface aquaculture. Especially for fish farming in mountain flat ponds, rice paddies, and large water surfaces with low aquaculture density, using floating fish feed has more advantages than using other feeds.
In terms of aquaculture species, both freshwater and marine fish, except for a few benthic fish that are extremely difficult to domesticate and feed on the surface, are able to feed well on floating fishing feed, such as famous and excellent species such as sea bass, snakehead, ornamental fish, frogs, turtles, catfish, as well as conventional aquaculture species such as grass carp, carp, and crucian carp. For species such as beautiful frogs and bass with special physiological functions, using floating feed for breeding is more convenient and can better demonstrate their superiority.
