摘　　要： 2005年12月-2006年5月,采用实地调查、资源调查、走访调查等方法,对梅江干流开展鱼类资源调查研究,本地区鱼类以鲤形目为主,占总种数的69.23%,其中又以鲤科鱼类为最多,占鲤形目的68.89%;其次是鲈形目和鲇形目,分别占总种数的15.38%和10.77%。此次调查采集到21种在《广东淡水鱼类志》梅江水系没有记录的鱼类。梅江鱼类可划分为热带平原、江河平原、中印山区、上第三纪和北方平原五个鱼类区系复合体。同时,本文探讨了梅江鱼类资源的合理开发与保护对策。 An investigation on fish resources in the Meigjiang River of Meizhou was carried out from December 2005 to May 2006. By use of collecting fish specimen, consulting relevant documents and visiting the local, integrating record in the past reference, we have collected 42 fishes and studied 65 species altogether in this area, which belong to 6 Orders, 17 Families and 42 Genus. Cypriniformes is the dominant species in this area, which accounts for 69.23% of the total ; Cyprinidae is the largest Order, which accounts for 68.89% of the Cyprinidae. Siluriformes and Perciformes account for 15.38% and 10.77% of the total respectively. 21 fishes which were not recorded in the part of the Meijiang River in the book entifled ＂The Freshwater Ichthyography of Guangdong＂ were collected. The fishes in the Meijiang River can be divided into the tropic and plain ichthyofauna compound body, rivers and plain ichthyofauna compound body, Sino- India mountain area ichthyofauna compound body, early Tertiary Period ichthyofauna compound body and northerm plain ichthyofauna compound body. This paper also discusses the reasonable exploitation and conservancy of fish resources in the Meijiang River.
