PurposeResearch
ObjectivesObjectives

1. To obtain estimates of the distribution and abundance of Nephrops burrows at Fladen, the Devil's Hole, the North Minch, South Minch, Sound of Jura, Clyde, Moray Firth and at the Noup using underwater television (UWTV) video cameras.
2. To use the video footage to record occurrence of other benthic fauna and evidence of commercial trawling activity.
3. To collect trawl caught samples of Nephrops for comparison of reproductive condition and morphometrics.
4. If trawling occurs, record and retain marine litter obtained from trawling as part of the MSFD.
5. To collect sediment samples at each UWTV station.
6. If time and conditions allow, to recover and deploy SPAN moorings in the Clyde and along the North coast.
