Compression injury: When a certain part of the fish body is pressed for a long time, it will cause the blood flow of the tissue at the site to be sluggish, causing tissue atrophy and necrosis. For example, in the case of fish transporting tools or weighing containers where the water is too little or no water, the fry and fry are piled up and squeezed and injured. This type of fish injury is often caused by ulcers in the base of pectoral fins or pelvic fins. It is because the fry is supported by the pectoral fins and pelvic fins or fins while under pressure, which is due to the pressure of body weight. This type of injury is more likely to occur in leaner fry. Bruising or abrasions: During fishing or transportation, fish often causes damage to the fish due to improper use of tools or careless handling. Lighter scales, broken fins, abrasions to the skin, and severe muscle damage. This situation is most likely to happen during winter and summer fishing. Although it will not cause fish to die on the spot, it will cause subsequent inflammation in the wounded parts of the fish and cause chronic death of the fish. Prevention and control means: It is difficult to treat fish after injury. Therefore, prevention should be the main method. Fishing tools (such as the softness of the cable, etc.) and shipping containers should be improved to minimize the number of fishing and transportation. During fishing and transportation, certain operations must be performed. Be cautious and choose the right time (such as when the water temperature is not high during the day). If you really need to drain the water to weigh, you need to have a fast flow and the drain time is not too long. The weight (mantissa) of the heavy fish is reduced as much as possible, and the quantity is less often, so that the life of the fish is mainly preserved.
