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.

Introduction of the poultry ring die feed pellet machine

Do you need some ways about the poultry feeding? Come to learn about the ring die feed pellet machine.

Our chicken ring die feed pellet machine is a type of feed machinery for commercial purpose, belonging to the industrial pellet mill. The basic function of a ring die feed pellet mill is to produce high quality pelleted feeds for chicken, cattle, pigs, horse, duck etc. in large scale feed pellet plant.

Ring Die Pellet Machine application:

Mainly suitable for medium-and small-scale farming professional households and other processing of various livestock and poultry and aquatic pellet feed can reduce the cost of aquaculture. Animal feed machines can be used for raising rabbits, chickens, ducks, geese, fish, pigs, cattle, sheep, aquatic products, and so on. 

Purpose of feed quenching and tempering

A. Conducive to feed granulation molding

B. Improve feed digestion and absorption rate

C. Increasing the stability of aquatic pellet feed in water

D. Increasing the output of the granulator and reducing the power consumption E. Reducing the wear of the stamper and the pressroll

F. Destruction and killing of harmful factors

G. 2~3 liquid components can be added during quenching and tempering

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.
