Nephrops - TV-assessed burrow density 2007-2014 (average number of burrows)
Nephrops norvegicus is a mud burrowing species that constructs recognizable burrow complexes with distinctive crescent-shaped entrances. Stock assessments make use of size composition data from catches, combined with information on stock abundance obtained from underwater television (UWTV) surveys. At each station, a custom built sledge is towed along the sea bed and all Nephrops burrow complexes are counted and used to derive density estimates (as shown in this data layer).
