Synopsis

The fish populations of the Rockall Trough were poorly known until the early seventies, when there was an interest in the possible exploitation of the demersal fish of the upper slopes. These surveys were carried out by fisheries laboratories with commercial trawls fished on paired warps. At the same time the SMBA began an investigation into the seasonal aspects of the fish of the slopes, using paired warp and single warp otter trawls and an Agassiz trawl. These studies have resulted in a wealth of information on the fish collected by several towed gears and have enabled comparison to be made between different trawls. Of particular interest has been the difference in abundance and biomass estimates between paired and single warp trawls. The small amount of information on the biology of the fish species is briefly reviewed and the populations of the Rockall Trough are considered in the broader context of the northeast Atlantic.
