No abstracts are to be cited without prior reference to the author.Norway lobster (Nephrops norvegicus) is of great commercial importance throughout the Northeast Atlantic and Mediterranean, where it lives in burrows within muddy sediments. In several European countries it is assessed using towed underwater TV techniques. This method is particularly suited to Nephrops because the application of normal fishery‐dependent stockassessment methods is not applicable to this species for a number of reasons. The TV methodology relies on the visual assessment of a known surface area of seabed. The number of Nephrops burrows, whose features are distinct, can be counted and their inhabitants quantified. It follows that, in theory, the same can be done for other organisms or key ecological features which appear on the footage. In this study we report the results of two underwater TV surveys (2009 and 2010) carried out jointly by Italy and Croatia in the Pomo pit, an area of the Adriatic Sea important for its Nephrops ...
