Intentionally Introduced and Transferred Fishes in China's Inland Waters

Abstract

Investigations showed that 72 exotic species and nearly 100 native species of fishes were intentionally introduced and cultured in the inland waters of China. The most influential species were Chinese carps and tilapias, which constitute most of the production in China’s freshwaters. The main purposes of introduction involved aquaculture, sale, ornament, resources conservation and biological control. Impacts included ecological deterioration and economic loss. To solve these problems, cooperation of legislation, administration, education and technical assistance are the top priority.
