First, ordinary Pelteobagrus fulvidraco: the natural distribution is very wide, the market adaptability is good, most markets in the country like this species. 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.

Second, Watts: the natural distribution is slightly narrow, and the adaptability of the market is not as good as that of ordinary yellows. except for the Chongqing market, other markets do not like it very much. The adaptability is not as good as that of the ordinary yellow catfish, but it grows well, and it is the best of all the yellow catfish, and the growth difference between the sexes is not as large as that of the ordinary yellow catfish, so it is generally not necessary to eliminate the female in the process of culture; it is difficult to adjust the body color.
