Introduction

Recently the influence of an electric light on the capture of the main groups of deep sea animals by a midwater trawl was described and discussed (Clarke & Pascoe, 1985). With regard to fish it was shown that at depths close to 800 m the total number, the total volume, the volume of the ten largest and the volume of the single largest fish all increased significantly when an electric light was used on the headline of the trawl when compared with controls with the light off. These experiments were carried out both in the Bay of Biscay and off Madeira.
