Although scientific interest on jellyfish ecology has substantially increased in the last decades, little is known on the role of potential predators shaping their population dynamics. Jellyfish were long considered as ‘dead ends’ within food webs, and therefore overlooked as potential food source for higher trophic levels, e.g. fishes. Here this question is tackled by using comprehensive laboratory experiments assessing fish predation on jellyfish. The approach included all the life stages (polyps, ephyrae and medusa) of Aurelia sp. versus more traditional aquaculture feeds in an easily farmed opportunistic fish, the gilthead seabream Sparus aurata (L.). Results revealed that all life stages of Aurelia sp. were accepted as a source of food by S. aurata,...
