Abstract European anchovy (Engraulis encrasicolus), usually found in the southern seas of Europe, increased its abundance and distribution in the North Sea during the mid-1990s. The causes for this increase are unknown but relevant to the management of commercial species like herring because there is potential overlap in resource use between the two species. The international bottom-trawl survey provides spatially referenced data on adult anchovy since 1965. Using spatially explicit generalized additive modelling, we investigated their main distributional patterns and the effects of environmental and biological variables (such as sea surface temperature, water depth, planktonic prey) on the dynamics of adult anchovy. The aim of the study was to identify which variables co-vary with the spatio-temporal dynamics of anchovy and to identify biologically meaningful relationships so as gain insight into the mechanisms that may control the population increase in the North Sea.
