The historical and contemporary knowledge on the elasmobranchs of Cananeia and adjacent waters, a coastal marine hotspot of southeastern Brazil

New Occurrences of the Tiger Shark (Galeocerdo cuvier) (Carcharhinidae) off the Coast of Rio de Janeiro, Southeastern Brazil: Seasonality Indications

“…According to [ 49 ], some of the criteria employed to identify a nursery area are a high frequency of sharks and the repeated use of the habitat over the years. Two other areas on the coast of the state of São Paulo, southeastern Brazil, are also considered nurseries, thus demonstrating the need for specific conservation measures [ 40 , 50 ].…”

Retrieving records of a rare and threatened shark in a mosaic of marine‐protected areas of southeastern Brazil

“…During the interviews, information was obtained on the presence of the species in the local fisheries, date, area and capture device (or means of observation) [for more information on monitoring, see Santos et al . (2022)].…”

“…This historical lack of information on G. cirratum in its southern limit of distribution, combined with the advances in fishing in recent decades, with a consequent reduction in many shark populations, especially in the southeast and south of Brazil (Barreto et al ., 2016; Chelotti & Santos, 2020; Viana, 2013; Vooren & Klippel, 2005), made this species one of the first to be considered vulnerable in the regional list of endangered fauna of the São Paulo State (São Paulo, 1998). In 2018, its status was re‐evaluated as critically endangered (SMA, 2018); nonetheless, some authors claim that this species could already be regionally extinct (ICMBio, 2018; Wosnick et al ., 2021), due to the absence of formal records from São Paulo since the 1960s (Chaves et al ., 2019; Costa & Chaves, 2006; Gadig et al ., 2001; Graça‐Lopes et al ., 2002; Santos et al ., 2022).…”

“…In this context, the authors of this study used the Fishers ecological knowledge (FEK) of artisanal fishers, recreational anglers, fishing guides and spearfishers to recover occurrence records and biological data of the Atlantic nurse shark in south coast of the state of São Paulo. The study was carried out in the south coast of the state of São Paulo, in southeastern Brazil, in an area considered a hotspot for local biodiversity and also an area with the only official record of G. cirratum for the region (Figure 1) (RAMSAR, 2007; Santos et al ., 2022; UNESCO, 2005). During the interviews, information was obtained on the presence of the species in the local fisheries, date, area and capture device (or means of observation) [for more information on monitoring, see Santos et al .…”
