Selectivity in trawl fishing gears

Scottish Marine and Freshwater Science Vol 8 No 1

In this manual we describe the different stages of the fish capture process, highlight how different parts of the gear may influence selection and identify possible design changes which can alter the selectivity of the gear. The intention is to make fishermen, net makers and fisheries managers more aware of the possible modifications that can be made to their gears so that they can design and develop gears with a selective performance suitable for their particular fishery. Individual factsheets may be downloaded from the Discardless project website.
