1996 - Centre for Environment, Fisheries & Aquaculture Science (Cefas) Nephrops underwater TV Surveys - VHS and DVD footage

Underwater TV (UWTV) surveys are carried out in the Eastern Irish Sea and North Sea to record the occurrence of Nephrops ( Nephrops norvegicus ) burrows. This information forms the basis of the Nephrops assessment to develop fishery independent indicators of stock size, exploitation status and catch advice. The standard methodology involves the use of a sledge mounted camera to film the seabed at a fixed set of stations conducting TV tows for 10 minutes.
