Distribution and Trophic Ecology of Bathylagus euryops (Teleostei: Microstomatidae) Along the Northern Mid-Atlantic Ridge
The distribution and trophic ecology of many deepwater fishes in the North Atlantic are well documented, particularly for commercially important species. However, few studies based on large-scale latitudinal and vertical gradients have been performed. In June 2004, the MAR-ECO (Census of Marine Life...

The distribution and trophic ecology of many deepwater fishes in the North Atlantic are well documented, particularly for commercially important species.

Catch data revealed Bathylagus euryops to be the biomass dominant species and ranked 3rd in total abundance. Generally considered to be a relatively stable and homogenous environment, the deep sea contains a diversity of habitats that are often related to changes in topographic features and associated hydrography.
