中文摘要：于2014年3月至2015年7月从我国雷州半岛红树林区采集成鱼和幼鱼样本共1720尾,在依据Fish Base等鱼类形态分类系统进行鉴定的基础上,利用COⅠ条形码技术确认存在94个物种,分属11目33科72属。结果表明:红树林区鱼类种群极其丰富,其中鲈形目(Perciformes)鱼类物种最多,为59种,占总物种数的62.77%,其次是鲱形目(Clupeiformes)和鲻形目(Mugiliformes),分别占6.38%和5.32%。鲈形目中又以虾虎鱼科(Gobiidae)为优势类群,含29种(占30.85%)。按生态类群分:海洋洄游鱼类最多,占物种总数的32.98%,其次为海洋偶见鱼类、两侧洄游鱼类,分别占22.34%、17.02%,以虾虎鱼类物种为主的红树林定居鱼类约占11%。本研究表明红树林生态系统是许多海水、淡水和洄游性鱼类在特定生活阶段的重要栖息地和育幼场所。另外,COⅠ条形码技术可有效快捷地鉴定出红树林海域的鱼类。

外文摘要：We randomly collected 1720 young and adult fish from March 2014 to July 2015 in mangrove waters of Leizhou Peninsula during a fish survey to enrich local fish species database and the ecological and environmental status, and to test the applicability of combining the CO I barcode technology with FishBase and other fish morphological classification schemes. In total, 94 species were identified, belonging to 72 genera, 33 families, and 11 orders. The results show that fish species in the mangrove waters was abundant, of which Order Perciformes were the most abundant fish （59 species or 62.77% of the total species）, followed by Clupeiformes （6 species, 6.38%）, Mugiliformes （5 species, 5.32%）, and Characiformes （2 species, 2.13%）. Of the Perciformes, gobies were dominant species （29 species, 30.85%）. In addition, marine migratory fish were the highest species taking 32.98%, followed by marine stragglers 22.34%, amphidromous 17.02%, and few estuarine species. In addition, 11% of major gobies inhabit the mangrove estuarine. Therefore, mangrove waters are an important habitat and nursery field for many marine, fresh, and migratory fishes. On the other hand, CO I barcoding has been proved practical in studying the fish biodiversity.
