| Popis: | 93 This study attempted to understand temporal and spatial species composition of dominant and by-catch fish larvae of larval anchovy fisheries during the period of 2002 to 2005 in coastal waters around Taiwan. From the analysis of the larvae fish compositions in different coastal waters of Taiwan, it showed significant difference in different waters. In the Kengfan, Fangliao, Wanli and Fulong waters, the dominant species were Encrasicholina punctifer and E. heteroloba, while in the Tansui and Hsinchu waters then were sardine and E. punctifer, but in the Taichung waters then were Thryssa and E. punctifer. The monthly by-catch rates of Tansui were 0.84%~76.65%. In the Hsinchu, Taichung, Fangliao and Kengfan were 0.31%~18.77%, while in the Fulong and Wanli were less than 8.49%. The compositions of by-catch larval fish varied spatiotemporal. Dominant species group of by-catches were Synodontidae, Leiognathidae, Loliginidae, Sillaginidae, Gobiidae and Carangidae in the Tanshui water, Sillaginidae, Leiognathidae, Synodontidae, Gobiidae, Sparidae and Apogonidae in the Kengfang water, Leiognathidae, Loliginidae, Sillaginidae, Synodontidae, Ophichthidae, Nemipteridae and Apogonidae in the Fangliao water, Sillaginidae, Leiognathidae, Sparidae, Siganidae, Mugilidae and Megalopidae in the Hsinchu water, Leiognathidae, Kuhliidae, Gobiidae, Sparidae and Sillaginidae in Taichung water, Pomacentridae, Synodontidae and Mugilidae in the Fulong water, and Sparidae, Apogonidae, Carangidae and Leiognathidae in the Wanli water. Except Taichung, it was also found the temporal variation of by-catch species composition in the different coastal waters around Taiwan. |
