The oceanographic vessel 'Vizconde de Eza' has begun the 'Flemish Cap 2023' campaign to assess the populations of key fish species in the Great Bank of Newfoundland. The campaign, conducted by the Spanish Institute of Oceanography (IEO), will evaluate the abundance, biomass, and demographic structure of the fish populations and the oceanographic conditions of the area. The information gathered will be used to assess fishing resources and for studies of a biological and ecological nature.
