Fish indicator species The fish species recommended for monitoring in this manual provide a good cross section of the fish community on a coral reef. Key, or indicator, species were selected based on a several criteria including trophic level in the food chain, fishery value and type, and general reef health indicators, with the understanding that a healthy reef should support a diversity of fish from piscivores (fish eaters) to planktivores (plankton eaters). The key/indicator species and criteria are shown below. Certain species of fish are large and rare partly due to their natural life history and partly due to over fishing or loss of habitat. These are shaded grey. Any sightings of these outside the survey transects should also be recorded as an additional note. Additional species identified as a priority for your site may be added to this list. species trophic criteria: Fishery importance, ecological role, vulnerability Rabbitfish / Tafi Herbivores Fisheries.
