? Catfish and catfish are common fish in daily life, both of which belong to catfish. In fact, there are many kinds of catfish, among which catfish and catfish are two very important ones. Although catfish and catfish are similar in appearance, this is because they belong to catfish, which does not mean that they are the same species, they are not exactly the same. In fact, there are differences between catfish and catfish, which are not exactly the same in size, appearance and distribution, so they can not be confused, and they can be distinguished from these differences.
between catfish and catfish? 1. Body shape: To distinguish catfish and catfish, we can see their body shape, because the difference between them is relatively large. The size of the earth catfish is relatively small, the weight of the earth catfish often seen in the market is only more than one catty, the larger earth catfish individual is only five or six catties, and the larger one is less. Catfish, on the other hand, are very large, weighing up to 60 kilograms.
2. Spots: The spots on the earth catfish and the big mouth catfish are also different, which can be used to distinguish them. There are spots on the surface of the earth catfish, while there are no spots on the body of the big mouth catfish.
3. Growth rate: Both catfish and catfish can be cultured artificially, but their growth rates are different. Catfish are not only large in size, but also grow much faster than catfish, so they can also be distinguished from their growth rate.
4. Distribution area: Both catfish and catfish are distributed in China, but their specific distribution areas are different. Specifically, there are catfish in the north and south of China, while catfish mostly grow in the south of the Yangtze River, that is, in the south of China.
