Abstract: 21We followed landings of dusky grouper, Epinephelus marginatus, from 2013 to 2019. 22 We observed 1,896 individuals of dusky grouper, Epinephelus marginatus, in Copacabana, Rio 23 de Janeiro, from September 2013 to February 2019. The total weight of the catches was 6,065.57 24 kg, with an average of 1,442.50 kg/year and a std of 147.30 kg. 25 We integrated fishers in our study through citizen science (CS): individuals were trained 26 to monitor grouper gonads and supplied information on fishing spots an… Show more

“…We observed a total of 490 individuals, among which weights were obtained for 466 individuals and showed a total catch of 630.39 kg. Mature gonads for comb grouper, were observed in April, September and October: these spring months coincide with mature gonads being observed in dusky grouper [16,18,28] (Fig 2).…”

“…Even considering that comb grouper is of LC (least concern, IUCN Red List), there is an information gap concerning its diet and reproduction [11]. Thus, an optimistic prognosis is offered from the studies of dusky grouper and Copacabana [16], but there is a pessimistic prognosis for comb grouper due to its decreasing catches when the fishing effort is maintained at a constant level, as was observed for the Copacabana fishery.…”

“…Here, we chronologically describe the research results for garoupa, Dusky grouper. The most recent study (Begossi and Salivonchyk, 2019) showed relative catches and price stability. The studies that were begun by Begossi and Silvano (2008) included results about the local knowledge of fishers regarding diet and habitat, fishing locations, weight and length (TL), and stomach contents, among other features (sample of 40 individuals from 2006-2007).…”

This study was followed by that of Begossi et al (2016), which included fishing locations (Figure 1), weight and length (TL), macroscopic analysis of gonads by trained fishers (800 individuals from 2013 to 2015); : locations, weight and length (TL), macroscopic analysis of gonads by trained fishers (sample of 222 individuals, from 2016-2017), and prices from October, 2016 to November, 2017; and the study by Begossi and Salivonchyk (2019): 1,896 grouper observed from 2013-2018, showing catches and prices as relatively stable in Copacabana (the https://www.biorxiv.org/content/10.1101/759357v1). Genetic analyses were performed earlier for Dusky grouper (Priolli et al, 2014;.…”
