Managing industrial fishing activities remains an urgent and crucial challenge for marine biodiversity conservation and food security (Zhou et al., 2010). Massive and selected marine resources exploitation causes a considerable impact on marine fish stocks and ecosystems' structures (Pauly et al., 2005), causing death by accidentally catching non-targeted species of pelagic vertebrate top predators (sharks, turtles, marine mammals and seabirds) whose populations have severely declined in the last decades (Lewison et al., 2014; Nel et al., 2002; Stevens et al., 2000).
