The crustacean bycatch of seabob shrimp Xiphopenaeus kroyeri (Heller, 1862) fisheries in the Cananéia region, southern coast of São Paulo, Brazil

Do the day/night periods and tidal cycles modulate the abundance and distribution of Callinectes danae Smith, 1869 (Brachyura, Portunidae) in an estuary-bay complex from southeastern Brazil?

“…The life cycle of C. danae is characterized by sex-specific segregation, causing habitat partitioning in which males and juveniles of both sexes are present in upper estuaries, while adult females and mainly ovigerous females inhabit areas with marine influence and migrate to deeper and more saline places to hatch their larvae (Chacur et al, 2000). The species is intensely caught in shallow waters off the coast of Brazil by artisanal fisheries and is one of the main species caught as bycatch in the commercial Penaeidae shrimp fishery (Keunecke et al, 2009;Bochini et al, 2019).…”

Growth parameters, longevity, and mortality of the seabob shrimp Xiphopenaeus spp. (Decapoda: Penaeidae) in four important fishing regions of southeastern Brazil

“…However, these species are caught and monitored as seabob shrimp only (Ávila‐da‐Silva et al, 2018, 2019). The seabob shrimp ( Xiphopenaeus kroyeri sensu lato) is considered the second most important fishing resource in southeastern Brazil, accounting for 90% of all Penaeid shrimps caught in the coastal region (Bochini et al, 2019; Carvalho‐Batista, Terossi, et al, 2019; Mantelatto et al, 2016; Vasconcellos et al, 2011). Seabob shrimps account for 30% of commercial shrimp catches in the Gulf of Mexico.…”

“…The shrimp fishery is considered predatory due to the capture method, where bottom trawls with low selectivity are used, resulting in a high capture of non-target species that are discarded (Hall et al 2000). In Brazil, the target of this fishery are shrimps of economic importance belonging to the superfamily Penaeoidea (Dias-Neto 2011), however the participation of other shrimp species of no commercial interest is frequent in different states of Brazil: Santa Catarina (Branco et al 2015), Paraná (Robert et al 2007), São Paulo (Bochini et al 2019), Rio de Janeiro , and Sergipe-Alagoas (Santos et al 2016). Many species present in the bycatch of shrimp fisheries are more vulnerable than target species (Lira et al 2022), mainly because most of them do not have their catches reported and basic information on their biology is missing, which prevents researchers and decision makers to assess the real impact of this activity on the ecosystem, representing a threat to its future sustainability (Andrew et al 2007).…”
