摘要/Abstract

摘要： 2003年6月至2004年5月，通过底拖网作业收集鱼类标本对广西合浦儒艮国家级自然保护区及其邻近水域鱼类种数进行了调查，并走访当地鱼市进行实地调查.共记录到保护区及其邻近水域的鱼类14目41科57种，其中55种为硬骨鱼类，占总数的96.49%，另有2种软骨鱼类，占总数的3.51%.有41种为暖水性鱼类，占总数的71.93%.生态类型中底层鱼类共37种，占总数64.91%.区系特征以北太平洋和印度太平洋区系为主.掠夺性获取和开发以及环境污染是目前这一水域鱼类资源面临的最大威胁，针对以上威胁提出了相应的保护对策.

Abstract: An investigation was made on the fish resources and fish habitats of Hepu Dugong State Nature Reserve and its adjacent waters from June 2003 to May 2004. The local fish markets were surveyed, and fishermen and fishmongers were interviewed to get fishery information. A total of 57 fish species belonging to 41 families and 14 orders were recorded, among which, 55 were bony fish, and 2 were elasmobranch. There were 41 fish species belonging to warm-water fish, and 37 fish species belonging to benthonic fish. The faunal characteristic was mainly of Northern Pacific and Indo-Pacific fauna. Devastating fishing and environmental pollution were the most serious threats to the local fishery resources, and some counter measures were proposed for conservation and management of the resources.

Key words: Windbreaks/shelterbelts, Highly effective and mu lti functional management, Indices and criteria
