![]() In this rig the sweeps have two main roles, firstly to herd in some of the bottom living fish such as flats and monkfish that are a valuable bycatch in a prawn net. ![]() Nephrops do not react well to this herding by the sweeps, with the effective herding area being only a few metres ahead of the wing ends of the trawl. The sweeps etc are made up of combination rope (a wire and rope mix) to withstand the abrasion of being hauled across the seabed to herd fish into the mouth of the trawl. These sweeps and bridles can range from 35 metres right up to 140 metres in length on each side of the net. Sweeps and bridles are used between the trawl and the trawl doors with this net as the fishermen usually want to catch some of the other bottom-dwelling fish to boost their landings. It is a long winged low net with lightweight ground gear for towing over the soft muddy areas where Nephrops are found. This trawl is specifically designed to catch Nephrops also known as Langoustine and Dublin Bay Prawn, but are commonly referred to as 'prawns' by those in the UK industry, hence the name prawn net.
