Objectives1. To survey the seabed and sample benthos at the experimental site off Anglesey (ref. 53.25.5N; 04.01.5W) fished intensively with a beam trawl fitted with chain mat for the last time in October 1994.
2. To estimate the survival of animals caught in the cod-end using the on-board survival system over a prolonged period. No survival experiments were made.
3. To measure the survival of animals which pass through the mesh of the beam trawl. No survival experiments were made.
4. To film predators attracted to baited camera frames/and/or a frame mounted video camera on the sea bed using various components of the by-catch.
5. To quantify the number of macroepibenthic animals moving onto trawled tracks and control areas by sampling with a 3m beam trawl.
6. To estimate amphipod abundance with baited traps.
7. To undertake comparative trials with beam trawls and scallop dredges in Manx waters, to establish by-catch composition and damage to the benthos in co-operation with Port Erin Marine Laboratory (PEML), Isle of Man.
