It is mainly found in Asia and has become one of the most common Of the food fish.Due to less disease, cold hardy, then available on the market, but also delicious meat, it is popular with farmers and consumers.This article on the lineage of the chromatin type was studied for the classification of the fish As well as to determine the status of evolution to provide a theoretical basis.
