Advantages Of Floating Fish Feed

Because the extruded floating fish feed can float on the water surface for a long time, the feeding situation of the fish can be observed well after feeding, and it is convenient to adjust the feeding amount according to the feeding situation of the fish. At the same time, the growth and health status of fish on the water surface can be understood more accurately according to the change of fish’s food intake. The farmers can calculate the amount of bait according to the breed, specification, quantity, water temperature, bait casting rate and so on, so as to quickly feed, save a lot of time and improve labor productivity.

Under the processing conditions of high temperature and pressure, starch in the feed is ripened, fat and other more conducive to digestion and absorption, fiber structure and cell wall are destroyed and softened, gossypol in cottonseed meal and anti-trypsin and other harmful substances in soybean, so as to improve the palatability and digestibility of the feed. In addition, due to the physical and chemical changes during the extrusion process, the powder produced by the extrusion feed is generally less than 1%, which directly improves the effective utilization of feed. Under normal conditions, the use of extruded floatation feed for fish can save 5-10% of feed compared to powder or other pellet feed. And you could use the dry type fish feed machine if you have a small farm.

The extruded feed of planktonic fish does not remain in the water for long. The floating time of high quality floating fish feed can be up to 12 hours, and it is easy to observe and control. It reduces or avoids the pollution of powder and residual bait to the water body, which is very beneficial to environmental protection and the growth of fish.

In the way of breeding, the extruded feed of planktonic fish has wide applicability. Floating fish feed can be used for pond fish culture, paddy field fish culture, running water fish culture, cage fish culture, factory fish culture, large watertight culture, etc. The use of floating fish feed has more advantages than other kinds of fish feed, especially for the low-density fish culture in mountain ponds, rice fields and large-scale intensive water surface culture.

What should do if the fish has vertical scale disease?

    What should I do if the fish has vertical scale disease? Most aquarists who keep ornamental fish find that the fish are helpless when they are sick. In order to avoid the disease of the fish, it is necessary to do daily feeding work, control the water quality and stabilize the water temperature, and do a good job in disease prevention. Vertical scale disease is also a relatively common disease in ornamental fish. How to treat vertical scale disease? Let's take a look.

    Vertical scale disease is also known as vertical scale disease, pine scale disease, pine skin disease and so on.

    [pathogen] is a bacterium similar to P. punctatae.

    [Symptoms] The symptoms of the diseased fish are that the body surface is rough, and most of the scales at the tail part open out like a pine ball, while the scales at the base of the scales are edema, and there are translucent or blood-containing exudates accumulated inside. liquid so that the scales stand up. A little pressure is applied to the scales, and the liquid substance is ejected from the scale sac, and the scales also fall off, sometimes accompanied by congestion of the fin base and the skin surface, protuberance of the eyes, and swelling of the abdomen.  Go to see the fish feed extruder machine.

     Sick fish are slow to swim, have difficulty breathing, turn their bodies sideways, and their abdomens are upward, and die after 2 to 3 days. When the water quality is not clean, the light is insufficient, the water is deficient in oxygen, the feeding water temperature is too high, and when the fish scales are scratched, it is easy to suffer from this disease. Goldfish and koi often suffer from this disease, which is more prevalent in spring every year. Among tropical ornamental fish, foamy oviparous fishes such as Perchidae, Bettaidae and Killiidae are often affected by this disease. The disease is difficult to cure, and even after it is cured, the color, luster, and posture are not as good as before.

 

[Treatment method] The diseased fish can be immersed in a tetracycline solution with a concentration of 1/50,000 unit for 1 hour; 2% sodium chloride solution and 3% sodium bicarbonate solution can also be mixed for 10 minutes; or chloramphenicol It can also be diluted with 1% of the above liquid and sprayed into a low dose, and it can be effective for several days after adhering to it.

The fish feed size of the crushed particles

Hello:

Do you know aquatic animals like the fish? Do you raise fish?

Ordinary fish feed The particle size of fish feed raw materials is below 40 mesh, and the digestion and absorption rate is greatly reduced. The crushing particle size of the compound feed for juveniles of common carp, grass, green and bream should pass through 50-60 mesh (0.30mm-0.25mm), and the crushing particle size of the compound feed for adult fish should pass through a 30-40 mesh sieve. 60-0.355mm ).

Aquatic feed requires finer particle size: the requirements of aquatic products for feed are different from those of terrestrial livestock and poultry, and the crushed particle size of aquatic feed is often finer than that of livestock and poultry feed, mainly for the following reasons:

1.Digestive capacity. The digestive tract of fish and shrimp is short and thin, and the ratio of its length to its own body length is generally much smaller than that of livestock and poultry, and its digestion and absorption capacity is also weak. At present, most of the fish, shrimp and crab species that are cultivated are carnivorous or partial carnivorous omnivorous aquatic products, and the length of their digestive tract is shorter than that of herbivorous or filter-feeding ones. In addition, fish and shrimps have weak digestion and absorption capacity for plant-based grains or cakes, and poor utilization of raw (immature) feeds. Therefore, crushing the feed finer helps to improve the utilization rate of the feed.  And do you know the feed mixer machines and feed dryer machines? The machines will be used in the fish feed production line.

2.Feeding environment. Aquatic animals eat in water, and the feed must be put into the water. Therefore, aquatic feeds are required to have a certain stability in water to keep their shape and nutrients from being lost. The smaller particle size helps to improve the water stability of the feed. At present, the common forms of aquafeed are hard pellets, extruded pellets, soft pellets and dough-like feeds. For the first two forms, there is a hydrothermal quenching and tempering extrusion treatment during the processing. Small particle size, water and heat are easily transferred to the inside of the powder particles, reducing the difference in the degree of treatment between the center and the surface of the particles, which is conducive to starch gelatinization and protein denaturation in the feed ingredients. This change process can make the difference between different powder particles. 

Interphase bonding, inlay, and forming stable particles under the action of extrusion. The degree of change is large, which can significantly improve the water stability of the feed. For the latter two forms, the finer powder particles will bond well with cohesive substances such as starch under the action of moisture, and the surface of the soft particles or dough will be smoother, which is beneficial to improve the stability of the feed water. In addition, when pulverizing with a relatively fine particle size, the powder particles are also embedded with each other, which is also beneficial to the stability in water.

3. Individual size. The individuals that breed aquatic products are generally not as large as livestock and poultry, and their calibers are also small. For the same aquatic species, the finished product is thousands of times larger than the individual seedlings. Especially for fish, shrimp and crab fry, the particle size required for crushing is correspondingly smaller.
