Multi-species grouper spawning aggregation fishery study in Papua New Guinea

This dataset contains spawning aggregation fish density and fishery data for two species of grouper (Epinephelus fuscoguttatus and E. polyphekadion) at a site in New Ireland Province, Papua New Guinea. Over two spawning months in 2013, fish aggregation density was estimated by divers conducting (point-count) underwater visual census surveys. A fishery targeting the two species of grouper at the spawning site was observed over the same period, with individual fisher catch and effort data collected and used to estimate catch-per-unit-effort. Other fishery information collected includes numbers of boats and fishers, hook size, and depth of fishing for catches.
