The classification of fish can be carried out from many aspects, for example, they can be classified from their living environment. Among them, if the living environment of fish is ocean, then it belongs to marine fish; If the living environment is fresh water, then it belongs to freshwater fish. However, there are also those that can live in both oceans and fresh water.
For example, pomfret itself contains many varieties, including those that can live in sea water and those that can live in fresh water. Among them, "silver pomfret" and "Chinese pomfret" live in the ocean. The specific distribution of these species is also different, and the specific waters and depths of their distribution are also quite different. For example, "silver pomfret" species are distributed in the range of 5-110 meters deep, and are more distributed in the Western Pacific region. There are relatively few species living in freshwater, mainly "red pomfret", also known as "freshwater white pomfret", which can be raised artificially, and can also be used as ornamental fish to live in freshwater.
As mentioned above, there are many varieties of pomfret, including both marine fish that can live in the ocean and freshwater fish that can live in fresh water. The species of pomfret that can live in fresh water are relatively few, and they can be raised artificially as economic fish; It can also be used as an ornamental fish. However, most of the pomfret species are marine fish, which can only live in the ocean, and these fish have adapted to the marine environment. Some of them live in deeper parts of the ocean and adapt to the environment with higher pressure. These pomfrets can not live in fresh water, if put into fresh water, they will not adapt to the situation, and may even die.
