The influence of net speed on catch is not only species dependent, but is also related to the size of the animal at the time of sampling. For some species the catch was independent of speed; for others, high‐speed tows resulted in greater catches than slow‐speed tows. The length‐frequency distribution of the catch is shown to be speed dependent for some species, with slow tows catching smaller animals and fast tows bigger specimens.
