There were 3 ecological group, i.e., migratory fishes (3 species), semi-migrated fishes (13 species), resident fishes (29 species) . The fishes in the Xinghu lake can be divided into the tropic and plain ichthyofauna compound body, China ’ s rivers and plain ichthyofauna compound body and early Tertiary Period ichthyofauna compound body. The change of fish community in Xinghu Lake was caused by various activities of human beings. The main economic species there was man-breed fish ,such as Tilapia aurea, Tilapia nilotica, Aristichthys nobilis, Hypophthalmichthys molitrix,among which Tilapia aurea and Tilapia nilotica have become dominant species by natural reproduction in the past 10 years. |
