Major Commercial Fishes Species and the Development and Application Prospect

Investigation was undertaken to study the species and resources of major commercial fishes in Guizhou. Results showed that there were 34 species of commercial fishes, among them, 22 species belong to Cyprinidae, account for 64.7%, 5 species belong to Bagridae, take 14.7%, 2 species belong to Siluridae, Serranidae, and Channidae, and take 5.9%, respectively. Most of the distribution areas are Wu River, Chishui River, Yuan River, Beipan River, Hongshui River, and Liu River. The yield of indigenous specific and high quality commercial fish was 1977 ton annually. Presently, the domestic study about the 11 species of fishes namely Culter alburnus, carp, Crucian carp, Silurus meridionalis, mudfish, Pseudoba grus fulvidraco, Pelteobagrus fulvidraco , Leiocassis longirostris, Channa argus, and C. asiatica were developed. Researches on culture and propagation were carried out and some progresses were achieved for 13 species named Spinibarbus sinensis, Varicorhinus simus, Tor brevifilis, Sinilabeo rendahli , Semilabeo notabilis, Schizothorax grahami, S. kozlovi, Procypris rabaudi, carp, Carassius carassius , Mystus guttatus , Cranoglanis bouderius, and Mystus macropterus. Among them, some species such as S. sinensis, V. simus, S. grahami, S. kozlovi, P. rabaudi, M. guttatus, C. bouderius, and L. longirostris are suitable for development and utilization in Guizhou.
