Marine fish abundance
Simon Jennings (Cefas & UEA)

Estimates of the abundance, production, distribution and size-structure of fish and other marine organisms are needed to predict their contributions to biogeochemical cycles and ecosystem function, to assess human and environmental impacts on ecosystems, and to predict fishery contributions to food security. This image shows the estimated distribution and wet weight biomass of marine animals weighing more than one gram and supported by pelagic food chains. Biomass predictions were made with a size-based food web model developed at the Centre for Environment, Fisheries and Aquaculture Science (Cefas).
