Abstract: The dusky grouper (Epinephelus marginatus) is a reef fish with high market, cultural and ecological values. Therefore, it is an important species to the food security of small-scale fishers in Brazil and in other coastal regions. Nevertheless, groupers can be susceptible to overfishing because they are large, sedentary and with delayed maturity. The lack of data on fishery catches and on the biology of dusky grouper can be an obstacle for the success of management measures. The main goal of this study was to c… Show more

“…Captures from fisheries improve nutrition and food security and help prevent or reduce poverty in developing tropical countries (Béné et al 2016). We show that fish considered as endangered or threatened, such as the dusky grouper (E. marginatus) (Begossi and Silvano 2008;Begossi et al 2016), are valuable food sources for local fishers. This species, in particular, is highly prized in regional and world markets (Trotta et al 2005;Begossi et al 2016).…”

This species, in particular, is highly prized in regional and world markets (Trotta et al 2005;Begossi et al 2016). Our results support the view that threats to coastal tropical fish can directly affect small-scale fishers and their livelihoods.…”

“…Projects in Brazil and other studies were performed in this way, especially with grouper ( Epinephelus spp.) [57,58]. These are studies in which both local knowledge and citizen science are involved; the local knowledge comes from fishers who provide their own knowledge (such as the reproductive period or knowledge on the aggregation of species), but the fishers also participate in a training program within the research project.…”

“…A comprehensive review of the dusky grouper was recently published by Condini et al [21], which included an evaluation of the current knowledge of the biology and ecology of this species. Some information that has already been synthesized is as follows [22, 24, 38–45]: groupers (Epinephelidae) includes about 160 species important economically, such as dusky grouper; it is a protogynous hermaphrodite fish, reaching female sexual maturity at 3 kg, with a mean length at first maturity (L50) of 43.8 cm (Ls) and sex reversal occurring at 10 kg [40, 41]. The largest specimens of this fish were caught in Tunisia (35 kg) and in Brazil (60 kg) [40].…”

“…Small-scale fishers in Northeast Brazil refer to red grouper when asked about the dusky grouper. We presented data on dusky grouper in previous studies [2, 8, 19, 35, 38], which focused on other aspects related to small-scale fisheries and LEK. With a focus on Brazil, we summarize selected studies on dusky grouper, present data on this species regarding production by small-scale fisheries in the southeast and present the LEK of groupers from small-scale fisheries along the northeast to the southern coast of the country.…”
