This paper reviews the current knowledge on the ecology of widely distributed pelagic fish stocks in the
North Atlantic basin with emphasis on their role in the food web and the factors determining their relationship
with the environment. We consider herring (Clupea harengus), mackerel (Scomber scombrus),
capelin (Mallotus villosus), blue whiting (Micromesistius poutassou), and horse mackerel (Trachurus trachurus),
which have distributions extending beyond the continental shelf and predominantly occur on both
sides of the North Atlantic. We also include albacore (Thunnus alalunga), bluefin tuna (Thunnus thynnus),
swordfish (Xiphias gladius), and blue marlin (Makaira nigricans), which, by contrast, show large-scale
migrations at the basin scale. We focus on the links between life history processes and the environment,
horizontal and vertical distribution, spatial structure and trophic role. Many of these species carry out
extensive migrations from spawning grounds to nursery and feeding areas. Large oceanographic features
such as the North Atlantic subpolar gyre play an important role in determining spatial distributions and
driving variations in stock size. Given the large biomasses of especially the smaller species considered
here, these stocks can exert significant top-down pressures on the food web and are important in supporting
higher trophic levels. The review reveals commonalities and differences between the ecology
of widely distributed pelagic fish in the NE and NW Atlantic basins, identifies knowledge gaps and modelling
needs that the EURO-BASIN project attempts to address.
