Preliminary assessment of the jellyfish bycatch captured off southern and southeastern Brazil

Abstract: Although the participation of the macromedusae has been relatively low, in areas of elevated concentration, the relative importance was high, making its participation almost exclusive among other zoological groups. Those registers of abundance and the respective areas of high concentration of macromedusae, which were associated to high primary production sites, may serve as a theoretical reference of the abundance of these organisms for future studies that aim to evaluate possible changes in jellyfish populati… Show more

“…As adults, these crabs can host several epibionts (e.g., algae, sponges, and cnidarians), thereby expanding the distribution of these sessile organisms while gaining protection (camouflage) (Nogueira Jr. & Haddad, 2005;Hultgren & Stachowicz, 2011). L. ferreirae experiences heavy fishing pressure in both juvenile (=immature) stages, when it is captured inside its host medusae, and adult stages because it shares the same habitat as commercially targeted shrimp species (Schroeder et al, 2014;Branco et al, 2015). Fishing efforts on the Brazilian coast are directed toward the capture of numerous economically valuable shrimp species, especially X. kroyeri (D'Incao et al, 2002;Castilho et al, 2015), which has caused a rapid decline in shrimp stocks and the stocks of bycatch fauna and has led to significant losses of spawning biomass and biodiversity (Castilho et al, 2008a).…”

“…Previous studies have documented associations of decapod crustaceans such as caridean shrimps (Palaemonoidea) (Marliave and Mills 1993;Moore et al 1993;Martinelli Filho et al 2008) and brachyuran crabs (Majoidea and Grapsoidea) (Nogueira and Haddad 2005;Sal Moyano et al 2012;Schiariti et al 2012) with scyphozoan in the medusoidphase. On the southern and southeastern coasts of Brazil, jellyfish, are accidentally captured as bycatch during trawlfishing for target species such as the seabob shrimp, Xiphopenaeus kroyeri (Heller, 1862) (Graça-Lopes et al 2002;Schroeder et al 2014). The capture of jellyfish, especially Rhizostomeae, potentially has an impact on any symbiotic species that are associated with them (Mianzan and Cornelius 1999).…”

“…As a result, recent studies involving the capture of macrozooplankton have been carried out for both artisanal fishing (BRANCO; VERANI, 2006;HADDAD, 2006a;NAGATA et al, 2009) and industrial fishing (SCHROEDER et al, 2014). In many cases, these are the only records available on the abundance and distribution of the group, due to the sampling limitations applied to marine plankton.…”
