The Atlantic goliath grouper, Epinephelus itajara, is a large-sized coastal fish that has been heavily overfished, mainly through spearfishing. In order to assess historical catches of the species, we interviewed spearfishers along three generations (young, middle-aged and old) in the traditional fishing village of Arraial do Cabo, southeastern Brazil. We identified a systematic and significant decline in the weight of the largest goliath grouper caught and in the number of individuals caught on the best day's catch through spearfisher generations. Today, the species is functionally extinct in the region and individuals are rarely sighted. Challenges to the conservation of goliath grouper populations throughout the Brazilian coast include the banishment of poaching as well as the support to alternative income sources through non-extractive uses, such as diving tourism.
