“…Jellyfish show opportunistic life histories, responding quickly to environmental changes by enhancing their feeding, growth, and reproduction in optimal conditions, thereby reaching massive population size. These proliferations have a wide range of implications both ecological and economic interfering with fishing activities (Purcell and Arai, 2001;Lynam et al, 2006), killing farmed fish (Doyle et al, 2008) or even acting as vectors of fish pathogens (Delanoy et al, 2011). Hence, identifying the factors shaping the population size of jellyfish is fundamental to achieve an ecosystem approach to fishery management (Lynam et al, 2005).…”
