Indications of structural changes in the marine ecosystem, catch ratios of predatory and plankton feeding fish

Year: 2005
From collection: Vital Water Graphics
Author: Philippe Rekacewicz, UNEP/GRID-Arendal
Description:
Three-quarters of fish stocks are currently exploited to the maximum extent, if not excessively. The Northeast Atlantic Ocean continues to exhibit declining catches, as well as a shift towards fish at lower levels in the food chain. This graphic illustrates the decline in the catch ratios of predatory and plankton-feeding fish in the Northeast Atlantic Ocean from 1950 to 1995.
