... Additionally, a size-dependent selectivity of the gear can depend on the interaction between sex and/or size-dependent habitat use, as observed in some large pelagic sharks (Mucientes et al., 2009;Schlaff et al., 2014;Gonzaĺez-Andreś et al., 2021;Gennari et al., 2022;Kock et al., 2022), and the operational fishing depth of the gear. For instance, it has been shown that deploying hooks at an increased fishing depth can reduce the bycatch of P. glauca, Carcharhinus falciformis (Müller and Henle, 1839), Carcharhinus longimanus (Poey, 1861), and Carcharhinus obscurus (Lesueur, 1818) though the bycatch size composition of single species is not affected as observed in the pelagic longlines deployed in the Pacific Ocean (Williams, 1999;Hinke et al., 2004;Ward and Myers, 2005;Gilman et al., 2008). Indeed, juveniles and adults of large pelagic sharks are generally distributed along an inshore-offshore gradient (Branstetter, 1990;Heupel et al., 2007), respectively, rather than along a surface-deep water slope in the offshore waters. ...
