“…The southern region includes the states of Paraná, Santa Catarina, and Rio Grande do Sul (Figure 1). The collection of landing statistics for the state of Paraná, interrupted in 2008, was resumed in 2016 through PMAP-PR (Jankowsky et al, 2019), and these current data were used to revise data from 2008 to 2010 and to interpolate values for 2011 to 2015 using a linear cubic spline interpolation applied to the available time series. The same procedure was possible for the state of Santa Catarina, specifically for artisanal fisheries.…”

Landing data are the most basic information used to manage fisheries, although they are often unavailable or incomplete. The objective of this work was to reconstruct the national database of marine commercial landings for the Brazilian industrial and artisanal fisheries, from 1950 to 2015. Total landings increased strongly from 1950 to mid-1980s and suffered sharp decline in the early 1990s, mainly associated to the collapse of sardine fisheries. After that, another period of increasing landings was observed, but at a much lower rate. Industrial landings always surpassed artisanal landings in Brazilian waters, except for the beginning of the time series, when many industrial fleets had not started yet, and in the early 2000s, when a change in the methodology for collecting landing statistics was implemented in the state of Pará leading to an overestimation of artisanal landings. Artisanal fisheries have been declining since 2005, which is worrisome due to the social impact it may have on local income and food security. Regional differences were also observed, with industrial landings being always higher than artisanal landings in southeastern-southern Brazil, while the opposite was true for the northern-northeastern regions. Higher landings were observed in the southeastern-southern regions when both artisanal and industrial fleets were combined. Sardine and demersal fishes were the main resources landed by industrial fishers. Artisanal fishers caught more species than their industrial counterpart, featuring Xiphopenaeus kroyeri, Cynoscion acoupa, and Ucides cordatus. Although the fishing of Epinephelus itajara was banned in Brazil, it continues to be landed. Yet, catches of this species and others under some threat status are still not properly registered, including: Carcharhinus longimanus, Galeorhinus galeus, Sphyrna lewini, Sphyrna mokarran, Pristis pectinata, and Pseudobatos horkelii. Fishing resources not identified in previous landing reconstruction efforts, such as sea urchins and sea cucumbers, have now been reported. The database presented here should be continuously updated and improved. It is of paramount importance to resume the collection of landing statistics, including information on fishing effort, to assess the relative impact of fisheries and environmental factors on the main Brazilian fishing stocks.

“…The number of fishermen was estimated from the number of productive units, i.e. fishermen or vessels (Jankowsky et al 2019) involved in the fishery of S. brasiliensis, and the fishing gear used. It was considered that use of each type of fishing gear would involve a certain average number of fishermen on the fishing trip.…”

Fishing for serra Spanish mackerel takes place along the Brazilian coast.Studies in northern and northeastern regions show that has socioeconomic importance although risk of overexploitation. This article provides an assessment of fi sheries in the southeastern and southern regions, where there is a gap in knowledge. To build a regional perspective, fi shing monitoring data from Santa Catarina, Rio de Janeiro, São Paulo and Paraná were used. For more detailed analyses, data from São Paulo and Paraná were chosen. In these two states, census data were collected on the species and quantities caught, fi shing gear used and sales value. This fi shery, mostly artisanal, has socioeconomic importance. Santa Catarina has the largest production. However, Rio de Janeiro has the most signifi cant industrial fi shery. São Paulo and Paraná produces approximately 110 t/year, mainly using drift gillnets and encircling gillnets with a mesh size of 10 to 12 cm between knots. The harvest period is during the cooler months, between May and August for São Paulo and between June and September for Paraná.The ANOVA test did not show any signifi cant variations in CPUE, thus indicating stability.The results reinforce the need for adequate management.
