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 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.
3. To quantify the number of macro-epibenthic animals moving onto trawled tracks and control areas by sampling with a 3m beam trawl.
4. To estimate scavenging amphipod abundance with baited traps.
5. To estimate scavenger populations at an intensively fished site off Fleetwood.
6. To compare damage rates of indicator species such as starfish in areas of different fishing intensity, i.e. off Anglesey and Fleetwood.
7. To collect live invertebrate scavenger species for experimental feeding and behavioural studies at Conwy.
All the aims were successfully completed.
