于2012年7月至2013年6月逐月在广西钦州港茅尾海红树林潮沟进行水平拖网采样，调查该红树林仔稚鱼的种类组成和数量分布特征，分析其时间变化及其与主要环境因子（温度、盐度和潮汐）的关系．共采获仔稚鱼24种，隶属于15科18属，物种组成较简单，主要优势种为爪哇拟虾虎鱼（Pseudogobius javanicus）等．聚类分析结果显示茅尾海仔稚鱼物种组成时间变化较明显，主要分为3个群落，12月至次年1月为群落类型 I，2～3月为群落类型 II，5～11月为群落类型 III．仔稚鱼多样性与环境因子相关性分析显示仔稚鱼物种数及爪哇拟虾虎鱼个体数与潮位（高／低潮）存在显著性差异，美肩鳃鳚个体数与潮型（全日潮／半日潮）存在显著差异．仔稚鱼物种组成与温度、盐度相关性分析表明仅仔稚鱼总个体数与温度存在显著正相关．

Based on the investigation of fish larvae resources by monthly otter trawl surveys in the mangrove of Mao-weihai Bay from July 2012 to June 2013,species composition and abundance and environmental factors,mainly temperature and salinity and tideswere analyzed.A total number of 24 species of fish larvae belonging to 15 families and 18 genera were collected during the investigation.The structure of fish community was simple and it was com-posed of mostly offshore warm water species.Pseudogobius javanicus were the most dominant species in the man-grove of Maoweihai Bay.According to hierarchical clustering,the community structure of fish larvae could be divid-ed into 3 groups.The group I was from December to January;the group II was from February.to March;the group III was from May to November.The correlationanalysis showed species richness and abundance of Pseudogobius ja-vanicus were significantly related to tidal level (high /low tide)and the abundance of Omobranchus elegans was sig-nificantly related to tide patterns (diurnal tide or semidiurnal tide).The correlation analysis between community of fish larvae and environmental factors showed that only abundance of fish larvae was significantly and positively cor-related to the temperature.
