Research Abstract

1. The community structures of el Nino-influenced coastal ecosystems in tropical Pacific were investigated, with particular reference to fisheries potentials.
2. Underwater visual observation of fish fauna was conducted in the shallow reef habitats of eastern Indonesia. Over 400 species of fish have been identified, of which Pomacentridae and Labridae were dominant in terms of the number of species.
3. Species richness is an important measure of diversity in biodiversity studies. A new procedure for estimating species richness in species-rich assemblages such as coral reef fishes was proposed and discussed. Fisheries catch statistics were also analysed with data derived from North Sulawesi.
4. Patterns of abundance and recruitment in the coral assemblages of a reef in North Sulawesi were investigated through a combination of field surveys and experiments.
5. Population fluctuations in two predatory starfish species (Heliaster helianthus and Stichaster striatus) and their mussel prey (Semimytilus algosus and Perumytilus purpuratus) were studied in central Peru. Fisheries statistics were also collected for analysis in relation to el Nino phenomena.
6. Interspecific relationships were examined in sessile and mobile assemblages of subtropical western Pacific, as a basis for understanding variability in community structure of tropical coastal ecosystems.
