Fishers and groupers (Epinephelus marginatus and E. morio) in the coast of Brazil: integrating information for conservation.

Background: Groupers are a vulnerable but economically important group of fish, especially for small-scale fisheries. We investigated catches and local ecological knowledge (LEK) of diet, habitat, and past fishing experiences.

Methods: Landings, prices, interviews, and restaurants demand for two species, Epinephelus marginatus (dusky grouper) and Epinephelus morio (red grouper), were registered.
