As a culture object, the adaptability is slightly stronger and the growth is general, but there is a great difference in gender growth. In the process of culture, in order to improve the culture effect, it is generally necessary to eliminate female fish; it is not difficult to adjust body color. The disease resistance is not as good as Watson's, and the meat quality is not very good. The price of seedling is low.
