AbstractThe scyphozoan Pelagia noctiluca is one of the most abundant species of jellyfish in the western Mediterranean Sea and its population seems to be increasing. It is a voracious predator, consuming fish larvae, fish eggs, and the foods of zooplanktivorous fish. The heavy dependence of the economies of many Mediterranean European countries on fisheries highlights the need to understand the potential impacts of this jellyfish on commercial fish populations. In the frame of the Spanish National Project FISHJELLY, we investigated the potential impacts of P. noctiluca on fish larva populations during two oceanographic cruises along the Catalan coast in the summers of 2011 and 2012. On each cruise, 81 stations were sampled to determine the distributions and abundances of gelatinous predators and their prey (zoo- and ichthyoplankton). Here we present the spatial overlaps of P. noctiluca, zooplankton, and ichthyoplankton, and the predation impacts, calculated from the numbers of prey eaten, the digestion times, and their abundances in situ
