摘要
漓江光倒刺鲃金线鲃国家级水产种质资源保护区是广西第一个国家级水产种质资源保护区。为了评估保护区对于野生水生生物资源的保护和恢复效果,促进保护区功能的进一步完善,对该保护区开展了一次较为全面的野生鱼类资源现状调查。通过雇请专业渔民记录每日渔获物数据,以及对桂林市农贸市场所售野生鱼类的定期调查,共获得一个年周期的数据。统计表明,该保护区现有野生鱼类74种,较之前的66种增加了8种,分别隶属于6目17科62属。应用G-F指数法统计物种多样性表明,漓江野生鱼类物种多样性也由0.443提高至0.596,说明保护区的设立对于保护和恢复漓江的野生鱼类及其他水生生物资源起着重要的作用,今后应进一步完善保护区的配套设施,保证漓江野生鱼类资源能够尽快地恢复。
