Pathology and mortality associated with the mauve stinger jellyfish Pelagia noctiluca in farmed Atlantic salmon Salmo salar L.
Jellyfish can cause significant losses to the aquaculture industry. This report describes the clinical
presentation and pathology caused by the mauve stinger jellyfish Pelagia noctiluca (Forsskal, 1775)
in cultured Atlantic salmon Salmo salar L. in Ireland and highlights the potential consequences and
need for descriptive pathology of such interactions. P. noctiluca is a member of the cnidarian class Scyphozoa
(Order Semaeostomeae; Family Pelagiidae)and has worldwide distribution through the warm and temperate waters of the marine environment. This golden brown to purple jellyfish species lacks the benthic polyp stage and has a primarily pelagic habitat, although ocean currents bring it closer to coastal waters. P. noctiluca is frequently observed
from the west coast of Ireland especially during the autumn months, but large aggregations are not commonly reported. In a jellyfish survey carried out around Ireland in 2009, P. noctiluca was the most abundant species found, accounting for 93% of the overall catch (total wet weight of gelatinous species) (Bastian et al. 2011). Its distribution and
density were found to be heterogeneous, with great variation between regions (apparent North-South gradient in density) and sampling points (Bastian et al. 2011).
