NOTICE Changes in Biomass, Production and Species Composition of the Fish Populations in the Northwest Atlantic Over the Last
Fish populations in the Northwest Atlantic have undergone dramatic changes during the last 30years in response to environmental effects, exploitation and other anthropogenic factors. The primary objective of the session is to document changes in abundance, production and community composition and to...
