Investigating trophic partitioning in planktivorous reef fishes (Old ID 26411)

Principal Investigator

Plankton-feeding fishes are a major presence on coral reefs, and they are assumed to feed indiscriminately on plankton. Although research on herbivores and corallivores has revealed numerous distinct feeding behaviours and food p0references in these groups, planktivores continue to be perceived as generalists. This project will determine the breadth of planktivore diets using stable isotope analysis. This method can determine the abundance of carbon and nitrogen isotopes in fish tissues, allowing us to work out the origin of different types of plankton that each planktivorous fish eats. I expect this study will reveal a previously-undiscovered diet partitioning within planktivorous fishes.
