摘要

We describe the assemblage structures and spatial distributions of juvenile and adult small gobioid fishes in a mangrove estuary in Trang Province, southern Thailand. The 11,183 gobioid juveniles and adults collected during the present study were classified into three families, 19 genera and 36 species. The three most dominant species were Pandaka pygmaea, Acentrogobius kranjiensis and Acentrogobius malayanus, which accounted for 75.9, 15.0 and 3.8% of the total number of gobioids collected, respectively. Spatial differences in gobioid fish assemblages were found in a mangrove estuary and its adjacent marine area. The diverse gobioid fauna with a variety of lifestyles found at muddy-bottomed, low-salinity stations, which were mainly upper- and middle-reach stations, can be partly accounted for by the existence of the various microhabitats in muddy-bottomed areas around mangroves. These microhabitats may contribute to local fish catches because gobies are of great significance as prey species for piscivores, including commercially important fish in mangrove estuaries. The abundance of each gobioid species would contribute to the development of rational methods for assessing the effectiveness of mangrove conservation and rehabilitation programs.
