| Summary: | Pelagic coelenterates (Cnidaria and Ctenophora) and thaliaceans (salps and appendicularians) have been considered important consumers or predators in marine food webs for many years but have only been recognized as being important prey for many species in the last 20 years. Although gelatinous zooplankton are known to be important components of the diets of large predators such as sea turtles and ocean sunfish for a long time, they are also important in the diets of pelagic migratory species such as mackerel and salmon. We summarize data obtained from Northeast Pacific fish fauna based on extensive food habits surveys of pelagic and demersal nekton ranging from the Bering Sea to the California Current. We have identified a number of previously unknown predators of jellyfish from several geographic regions. We also show that the occurrence of coelenterate prey is generally much higher in stomachs of several fish species examined fresh at sea compared with that found in stomachs of the same species examined in ... |
