“…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).…”

“…Populations occur in both the North and South Atlantic (Miller et al 2012), as well as in all the major oceans (Mayer 1910). The species has a negative impact on tourism (Bernard et al 2011) because of its painful stings (Maretic et al 1991, Mariottini et al 2008), on aquaculture by overwhelming fish farms and killing fish (Doyle et al 2008, Delannoy et al 2011, and potentially on the success of fish stocks such as tuna (Gordoa et al 2013). In the Mediterranean Sea, P. noc-tiluca has been a recurrent problem for centuries (Goy et al 1989).…”

Four cohorts of the scyphozoan jellyfish Pelagia noctiluca were grown in the laboratory. For the first time, P. noctiluca was grown from eggs through to reproductive adults. The maximum life span in the laboratory was 17 mo. Pelagia noctiluca were first observed to release gametes at an umbrella diameter of 2.4 cm. Laboratory growth under steady feeding conditions showed initial growth followed by stagnation until dietary conditions were altered. A mismatch between the availability of optimal food and the presence of developmental stages may significantly increase the mortality rates of the young stages. Non-motile prey improved survival of ephyrae stages compared with zooplankton, but good survival and ephyrae growth were only obtained with a high-energy sea urchin egg diet. Maximal growth rates were up to 30% d −1 for young ephyrae and 1.5−4% d −1 for adults. Maximal growth rates were comparable between laboratory and in situ growth observations in the Ligurian Sea during 1969 and 2013. Combining observations would suggest that 230 d of continuous growth are required to reach the largest mean size observed in the wild (June 2013, mean ± SD = 15.6 ± 2.8 cm, range = 12−21 cm). We suggest that 90−120 d of continuous growth from planula larvae would yield reproductive individuals under ideal growing conditions. We discuss the daily prey abundances required by each individual to sustain basal metabolism and the observed growth rates.

“…Both fish kills and sublethal effects of jellyfish interactions with farmed fish can contribute to economic losses, e.g. through reduced growth due to stress or increased exposure to disease where jellyfish act as vectors (Delannoy et al 2011). Thus, understanding the extent of the problem as well as identifying key taxa responsible remains a challenge, if mitigation strategies are to be developed.…”

“…Wounds from jellyfish stings may subsequently be infected by bacterial pathogens, such as Tenacibaculum maritimum (MarcosLópez et al 2016). Although the pathogenesis and natural origin of these bacteria are obscure, it is clear that some jellyfish carry them and may thus be vectors of fish disease (Delannoy et al 2011). Problems also arise when the jellyfish themselves are not harmful, but their enormous densities clog the mesh of the pens and the gills of the fish, preventing oxygenation and water exchange between the cage and the surrounding water and leading to hypoxia and suffocation of the fish (Nilsen 2011, Lucas et al 2014).…”
