  • The ecological effects of Chinese sturgeon blocked below the Gezhouba Dam and effectiveness of protective measures for the fish were summarized in the paper.After the construction of the Gezhouba Dam,the reproductive stock structure of the sturgeon has been relatively stable.Certain river sections below the dam could meet the spawning demands,and the newly-formed spawning ground has been considered to play a vital role in maintenance of the species existence.Since the sturgeon commercial fishing was prohibited restrictly along the Yangtze River and the new spawning ground was protected in 1983,the resource of juvenile sturgeon at the estuary and the proportion of fully mature fish in stocks have increased remarkably,Although the Gezhouba Dam does not threaten the existence of the Chinese sturgeon,the direct or indirect impacts of the Three Gorges Dam on the sturgeon should be given high attention.
