Composition and distribution of copepod populations in a tropical estuary

The purpose of this study was to analyze the copepod composition and distribution in a tropical estuary in Pendas river, Johor Malaysia. Samples were collected monthly for six month period at three stations in this study area located at an elevation of 5 m above sea level with coordinates 1°22'...
