creation
Marine_Scotland_FishDAC_874
Scottish underwater TV surveys to estimate Nephrops burrow distribution and abundance, from Nephrops Functional Units of significance to Scotland. Underwater TV footage is taken at specified stations within Functional Units. The underwater camera is mounted on a towed sledge and tow duration is 10 minutes. Records of Nephrops burrows, Nephrops and other benthic fauna is recorded onto DVD for analysis and review.

Underwater TV footage is taken at specified stations within Functional Units. The underwater camera is mounted on a towed sledge and tow duration is 10 minutes. Records of Nephrops burrows, Nephrops and other benthic fauna is recorded onto DVD for analysis and review. The depth and distance travelled by the sledge as well as the camera height is recorded. Sediment samples are taken were practicable using a mini van Veen grab mounted on the sledge. Where necessary, Day Grab sediment samples are taken instead. Trawl caught Nephrops are sampled for length composition and maturity and morphometric characteristics.
