Russian experts discover a new type of fish feed additive
Russian fish farming experts have recently found that chitosan, a biopolymer extracted from the shells of marine crustaceans, can be used as a fish feed additive, making fish feed easier to transport; fish that eat feed containing chitosan become plumper and finer. Ordinary fish feed is processed into loose pellets, but during transport it easily crumbles from friction or squeezing, and once put into water it quickly swells and breaks apart from soaking, causing waste. Therefore, when processing fish feed, adhesive ingredients need to be added to strengthen

For feeding medium to large fish, green fodder can generally be fed directly after the soil is removed; for feeding small fish, it should be chopped or

Three Major Disease Prevention and Treatment Methods for Pond Fish in Spring and Summer
1 Carp Hemorrhagic Disease 1.1 Symptoms and Causes The scales on the abdomen of the diseased fish, the fin rays and the caudal peduncle become congested and red. The diseased fish float up close to the ice layer or float on the water surface, gather in groups and swim slowly near the pond edge, and gradually die. ① Hemorrhagic septicemia. The diseased fish appear normal on the outside, or the area under the abdominal scales is congested and red. When the diseased fish is dissected, blood-tinged fluid emerges from the body cavity, and the internal organs have petechial hemorrhages. The disease is caused by Aeromonas hydrophila. ② Brown blood disease (hemorrhagic gill disease). The gill filaments of the diseased fish swell and become dark in color, and some gill filaments

The main components of fish oil are: triglycerides, phosphoglyceryl ethers, lipids, fat-soluble vitamins, and protein degradation products. No toxic substances such as mercury, arsenic or lead have been detected in the bodies of marine fish, while potassium, copper, aluminum, cadmium and others are all below the permitted health limits, and pesticide residues are almost zero, so the quality of the oil obtained by processing fish and fish waste is reliable. 1. Fish is one of the high-energy substances, with each gram of fat containing 94 calories,
