This aimed to study the selectivity of juvenile fish and Nephrops caught by Nephrops gear on two vessels with different horsepower. Anecdotal evidence suggests that gears towed by low-powered vessels are more selective than those towed by high-powered vessels with the assumption that higher powered vessels can fish at faster towing speeds giving juvenile fish less opportunity to escape. There is also a perception that, in poorer sea states, greater power enables a vessel to maintain tension on the gear, making the codend less selective. Nineteen paired hauls were carried out but numbers of commercial fish caught was low. There were significant differences in relative catch rates and in selection between nets and vessels for hake but for Nephrops, whiting and haddock the relative catch rates did not differ between gears or vessels. There was no evidence that gears towed by a low-powered vessel are more selective for haddock, whiting and Nephrops than those towed by a higher-powered vessel. There is also no evidence of a difference in the catching performance of the two codends for haddock, whiting and Nephrops.
