“…In order to compare the results found in the present study with exploitation patterns found in other major fishing grounds, MTI values collected between 1950 and 2014 from the North Sea, Eastern Brazil and the West Coast of the United States were retrieved from SAU (Pauly, Zeller, & Palomares, 2020) and plotted with time. While the Brazilian fishing industry is mostly unregulated and continues to present signs of expansion (Fiedler, Port, Giffoni, Sales, & Fisch, 2017; Perez et al, 2003), commercial fisheries in the United States and North Sea are well developed and studied. Comparing the time course of MTI among regions provides the basis for resolving how differences in management can have contrasting effects on the exploited community structure.…”

“…Evidence indicates that legislation may not be enough to protect endangered species in Brazil. Fiedler et al [35], for example, recently demonstrated that numerous pelagic species with restrictions in terms of retention and trade, including the sharks Alopias superciliosus, A. vulpinus, Carcharhinus longimanus, and Galeorhinus galeus, continue to be freely landed and marketed in national territory but that such events are not adequately reported. It is worth mentioning that the restrictions for these species are outside the scope of Ordinance 445 discussed above, since they are either included in previous lists, as is the case of C. longimanus and G. galeus, or subject to international recommendations, as is the case for sharks in the genera Alopias and Sphyrna and for C. longimanus, which have recommendations for non-retention and nonmarketing coming from ICCAT and CITES (Appendix S6).…”

Brazil currently ranks as the 11th producer and 1st importer of shark meat around the world. Data available from the FAO software FishStatJ along with data from regional sources, such as governmental bulletins, scientific papers, gray literature and internet were revisited to identify the main issues surrounding pelagic shark fisheries, trade and consumption in the largest country in South America. Among the main findings, it was noted that Brazil has not properly collected fishery statistics since 2007, that many species of threatened sharks are freely landed and traded even though it is prohibited by local legislation and/or international recommendations (regional fisheries management organizations). The blue shark (Prionace glauca) is the most frequently recorded shark in the official bulletins and is currently a locally targeted species. Additionally, the significant imports of this species from 23 other countries that also provide fins for Asia has drawn attention in recent decades. Regarding consumption, shark is considered to be low-value seafood compared to more common fish, such as groupers and snappers, and most Brazilians actually do not know that they are eating sharks. At present, the proportion of threatened elasmobranchs (in which sharks are included) in Brazil (33%, of 145 species) exceeds the global rate identified for the group (25%), and, until the present moment, no measure related to the management of species has been implemented. As advice, Brazil urgently needs to restructure its fishery information collection systems, management strategies and to tighten sanitary and labeling regulations for the marketing of fish.

“…In addition, the large extent of the territory and the existence of generic norms (e.g. turtle excluder device) mean that, even if prohibited, many of these fisheries continue to operate and many protected species continue to be captured and sold (Fiedler, Port, Giffoni, Sales, & Fisch, 2017). The consequences of the impacts caused by human activities are magnified by the life‐cycle characteristics of sea turtles, such as late maturation, site fidelity to nesting grounds, slow growth, and longevity.…”

1. In Brazil, five species of sea turtles use the region for feeding and reproduction. For these endangered species, one of the biggest impacts on their populations is incidental catches in fishing gear. 2. In the state of Santa Catarina (SC)-Brazil, fishing is an important economic activity, with distinct and numerous industrial and artisanal fleets. These fleets incidentally capture all five species of sea turtle. 3. In the Canoa beach fishing community in the municipality of Barra Velha (SC), gillnet fishing holds great economic and cultural importance. The four main gillnet fisheries in this community are whitemouth croaker, leatherjacket/mackerel, hake, and grouper/catfish/flounder, the latter of which is carried out on rocky bottoms and is locally called 'malhão'. In this fishery, fishermen have reported catching sea turtles over the years, especially the green turtle Chelonia mydas. 4. In the present study, 1,998 sets were monitored between September 2010 and April 2011, of which 104 (5.2%) were of gillnets for whitemouth croaker Micropogonias furnieri; 324 (16.2%) were for leatherjackets Oligoplites spp. and mackerel Scomberomorus spp.; 1,261 (63.1%) were for hake Cynoscion spp.; and 309 (15.5%) were for grouper Epinephelus spp., catfish Genidens spp., and flounder Paralichthys spp. 5. Considering all fisheries, the incidental capture of sea turtles occurred in only 3% of the monitored sets. In all, 87 sea turtles were captured, 78 (89.6%) of which were recorded in the 'malhão'. Of these captures, 68 (87.2%) were C. mydas, eight (10.2%) were loggerhead turtle Caretta caretta and two (2.6%) were 'hard-shelled' turtles. 6. The direct mortality rate observed for C. mydas in the 'malhão' was 73.5%, which is the highest rate recorded in similar fisheries of the southwest Atlantic, thus raising concern for the protection of this species in the Atlantic Ocean.
