Rapid depletion of a large-sized grouper in Arraial do Cabo, Brazil
A recent paper published in Perspectives in Ecology and Conservation investigated historical catches of the
Atlantic Goliath grouper, Epinephelus itajara, through spearfishers’ knowledge. Results revealed a significant
decline in catches among spearfisher generations along three decades (1975-2008). Today, the species is
protected by a fishing moratorium and do not show signals of population recovery because of poaching. Dive
tourism is encouraged as a non-extractive use of the species.
