Abstract:
Distribution and abundance of zooplankton along the Eastern Coast of Thailand were investigated in March 2005 (dry season) and October 2005 (wet season). Fifteen phylum belonging to 42 groups of zooplankton were found. The abundance of zooplankton was greater in the dry season than that in the wet season. Arthropoda was the dominant taxon found in the dry season, followed by Annelida, Chordata and Chaetognatha respectively. In the wet season, the dominant phylum of zooplankton found were Arthropoda, followed by Chordata, Chaetognatha and , Mollusca respectively. The copepods found in the dry season were 30 species of 4 suborder such as Calanoida, Cyclopoida, Harpacticoida and Poecilostomatoida. Paracalanus crassirostris, Oithona simplex, Bestiolina similis and Oithona aruensis were dominant species in the dry season. While nauplius copepods, immature Paracalanus and immature Oithona were mostly found in the wet season.
