碩士 === 國立臺灣海洋大學 === 海洋生物研究所 === 103 === Till 2013, there are 27 families 56 genera 69 species of freshwater and estuarine fishes including 9 families 12 genera 12 species of primary freshwater fishes had been recorded from the Kinmen islands. The current project would process the native population monitoring of the endangered cyprinid species, Metzia mesembrinum as well as the native, rare inland-water fish ecological survey of Kinmen islands, Fujian Province, R.O.C. The native habitats with the fish population around 4065 individuals during middle of 2014, then reduced about 1/2 fish populations in total during May 2015 via mark- recapture method in the field which may cause by the threatening of population increase of tilapia. The botanical garden had been selected for restoration location of this fish in 2014. After the removal of tilapia, the great success of fish reproduction in summer of 2015 have been performed the great population growth up to 13075-14180. It is worth to make more effort for freshwater fish conservation and monitoring for the very important lowland freshwater and estuarine fish fauna in Kinmen Island by joining local people progress and governmental output for alien fish species removal.
