Aran Grounds Celtic Sea Nephrops Underwater Television Leg 1 Survey into the abundance and distribution of prawn shellfish. 1.To obtain 2016 quality assured estimates of Nephrops burrow densities from a randomised isometric grid of UWTV stations at 4 nautical mile spacing over the known spatial a bathymetric distribution of the Smalls Nephrops Stock (FU22). 2.To obtain 2016 quality assured estimates of Nephrops burrow densities from a randomised isometric grid of UWTV stations at 6 Nmil on the Labbadie, Cockburn and Jone's Banks (FU20&21). 3. To obtain 2016 quality assured estimates of Nephrops burrow densities from around 50 sites within the known spatial a bathymetric distribution of the Nephrops Stock off the south coast of Ireland (FU19). 4.To collect ancillary information from the UWTV footage collected at each station such as the occurrence of sea-pens, other macro benthos and fish species and trawl marks on the sea bed. 5.To collect oceanographic data using a sledge mounted CTD. 6.To sample Nephrops and macro benthos using a 3m beam trawl deployed at ~10 stations on the Smalls.
