Regularly eating steamed fish helps protect heart health
We often see reports in the media that "eating fish is good for the heart." However, Professor Wang Cunxin, an authority on fish research in China at the Institute of Oceanology, Chinese Academy of Sciences, reminded everyone in an interview with reporters that fish are divided into sea fish and river fish, with a wide variety of types, and different fish have different effects. Eating fish really can protect the heart. Professor Wang pointed out that eating fish is greatly beneficial to the heart, and this has already been confirmed. Eskimos and residents of coastal fishing villages in Japan have fish in all three meals a day, and their lower rates of cardiovascular disease are a good example.

What are the treatment methods for fish hemorrhagic disease?
[Causes] The factors causing goldfish to suffer from hemorrhagic disease are relatively complex, generally triggered by viral, bacterial and environmental factors: 1. Viruses, bacteria (generally considered to be Bacillus monas) and parasites invade the fish body, causing damage to the whole body or part of the fish. 2. Water quality. Whether using tap water to raise fish, or lake water or well water, it must be left to stand or exposed to the sun for 2-3 days before use. If used directly without treatment, at best it will cause congestion of the fins and scales, and at worst it will kill the goldfish. [Symptoms

How to identify fish species? Observing appearance and color is key
First, look at the size specifications of the fish species. Fish of the same species from the same pond should be uniform and even in size when harvested, with little difference in body length and weight. Conversely, poor-quality fingerlings with large individual differences and uneven sizes often result in very low overall survival rates due to competition for food, mixed genetic stock, poor rearing, and other reasons. Second, look at the body color of the fish species. High-quality fingerlings have vivid, glossy body colors. Generally speaking, high-quality silver carp fingerlings should have a silver-gray back and silvery-white sides and belly; high-quality grass carp fingerlings have a pale golden-yellow body color, with gray-black reticulated scales that are relatively prominent, and the more robust the fish, the more obvious the pale golden-yellow color; high-quality bighead carp fingerlings mostly have a pale golden-yellow body color, with black markings across the body not very prominent. If the fingerling's body color is relatively dark, or even blackish, it indicates that the fingerling is a weak fry or diseased fish; the gloss on the body surface of fingerlings is caused by the mucus layer covering the body surface, which is the fish's first barrier of defense against disease. Diseased fish or weak fry lack the mucus layer, and their body surface has no gloss.

What to pay attention to when stocking fish fry in reservoirs in winter
Every winter is the golden season for stocking fish species such as silver carp, bighead carp, grass carp, and black carp into reservoirs. But quite a few fish farmers report that within 2 to 7 days after stocking the fry, large numbers of dead fish and swimming sick fish appear on the surface of the reservoir water; these fish lose their luster and their body surface mucus increases. Based on the above symptoms, it can be inferred that the fish have contracted a typical case of "acclimation sickness." This disease is mainly caused by a drastic change in water temperature, in which the nerve endings in the fish skin are strongly stimulated, causing dysfunction of the internal organs, and its death

Large Icefish Processing Technology Part 2: Detailed Methods
II. Processing of Lightly Dried Large Icefish Products The processing technology for lightly dried icefish products is simple and convenient for storage, and because this kind of processing can preserve the inherent flavor of icefish, it is more popular among consumers than salted dried products. 1.

Detailed Introduction to the Preparation Methods of Medicated Fish Bait
Treatment and prevention of fish diseases generally use pond spraying of drugs and mixing drugs into feed for feeding, which is what we usually call the oral method. The effectiveness of the oral method in treating and preventing fish diseases depends on the preparation of the medicated bait. Several commonly used preparation methods of medicated bait in production practice and precautions are introduced as follows: 1. Preparation methods of several medicated baits 1. Preparation of pellet feed medicated bait: Calculate the required feed and drugs, spread the feed evenly on a plastic film (the thickness should be uniform, not
