A Review of the Impact of Parasitic Copepods on Marine Aquaculture
The global importance of parasitic copepods as disease-causing agents in marine aquaculture is discussed and a brief review of the environmental and husbandry factors that may affect parasiticCopepod abundance and the potential roles that parasiticcopepods play as vectors for other disease agents are provided.

Thermal limits and ocean migrations of sockeye salmon (Oncorhynchus nerka) : long-term consequences of global warming
Ocean surveys show that extremely sharp thermal boundaries have limited the distribution of sockeye salmon in the Pacific Ocean and adjacent seas over the past 40 years. Expand
Anisakidae and anisakidosis.
During the 1950s, Ishikura noticed in the fishing town of Iwanai, Hokkaido, an intestinal disease that frequently occurred in winter with clinical and histopathologic characteristics different fromExpand
Trophic relations in the subarctic North Pacific ecosystem : possible feeding effect from pink salmon
It is shown that the feeding effect from the pink salmon controls summer macrozooplankton and phytoplankton biomass in the subarctic North Pacific and the opposite phenomenon probably occurred when pink salmon was not abundant. Expand
Some anisakid nematodes from marine fishes of Japan and the North Pacific Ocean
A recent collection of anisakid nematodes from marine fishes from Japan and the North Pacific Ocean comprised a total of seven species of two genera; six of them parasitize fishes as adults, whereas one (Hysterothylacium sp.) occurred as larvae encapsulated in the host's abdominal cavity. Expand
Recent changes in age and size of chum salmon (Oncorhynchus keta) in the North Pacific Ocean and possible causes
Changes in age composition and size of adult chum salmon from rivers in Japan, Russia, and Canada were examined based on body weight and scale measurement data collected from 19 rivers. Expand
Annual changes in the population size of the salmon louse Lepeophtheirus salmonis (Copepoda: Caligidae) on high-seas Pacific Salmon (Oncorhynchus spp.), and relationship to host abundance
The population size of the salmon louse, Lepeophtheirus salmonis, was monitored annually in the summers of 1991–1997 by examining six species of Pacific salmon (Oncorhynchus spp.) caught by surfaceExpand
