FISH and FISHERIES, 2003, 4,1^24 Hundred-year decline of North Atlantic predatory ®shes
We estimate the biomass of high-trophic level ¢shes in the North Atlantic at a spatial scale of 0.58 latitude by 0.58 longitude based on 23 spatialized ecosystem models, each constructed to represent a given year or short period from1880 to1998.We extract over 7800 data points that describe the abun...

Summary: | We estimate the biomass of high-trophic level ¢shes in the North Atlantic at a spatial scale of 0.58 latitude by 0.58 longitude based on 23 spatialized ecosystem models, each constructed to represent a given year or short period from1880 to1998.We extract over 7800 data points that describe the abundance of high-trophic level ¢shes as a function of year, primary production, depth, temperature, latitude, ice cover and catch composition.We then use a multiple linear regression to predict the spatial abundance for all |
