Irregular fish scales can be caused by various reasons, and the following are some possible reasons:
1. Disease: Vertical scale disease: This is a common fish disease characterized by the outward expansion of fish scales, edema at the base, and accumulation of translucent or bloody exudate inside, leading to the erection of scales. This disease may be caused by improper water exchange or other reasons.
2. Injury or damage during fishing and transportation: Fish may experience physical damage such as compression, collision, or deformation of their scales during fishing, transportation, or aquaculture.
3. Environmental impact: If there are drastic changes in the environment where fish live, such as sudden changes in water temperature or quality, or impacts from chemicals, electricity, etc., it may lead to abnormal scale growth.
4. Genetic mutations: In rare cases, genetic mutations in fish may lead to abnormal scale growth and irregular appearance. This mutation may occur naturally or be influenced by external factors such as radiation, chemicals, etc.
5. Species characteristics: Some fish species already have a special arrangement of scales, such as the "three scales". The scales of these species may not look so neat, but this is their normal physiological feature.
To address the issue of irregular fish scales, the following measures can be taken:
For irregular scales caused by diseases, diseased fish should be isolated in a timely manner and treated accordingly.
During fishing, transportation, and aquaculture, physical damage to fish should be avoided as much as possible.
Maintain a stable living environment for fish and avoid drastic changes in water temperature and quality.
For irregular scales caused by genetic mutations, special treatment is usually not required, but if it affects the health or ornamental value of fish, it can be considered for elimination or genetic improvement.
Irregular fish scales can be caused by various reasons and require diagnosis and treatment based on specific circumstances. During the breeding or ornamental process, close attention should be paid to the health status and scale growth of fish, and problems should be detected in a timely manner and corresponding measures should be taken to respond.
