The survey methodology, vessel and sampling gear detailed were agreed in consultation with Cefas and the Marine Management Organisation (MMO). A dispensation from the MMO for the Provisions of Council Regulation 850/98 to catch and retain undersize fish for scientific research and 43/2009 specifically related to days at sea was obtained prior to commencement of this survey. The aim of the survey was to establish the abundance and composition of adult and juvenile fishspecies within the area of the Dogger Bank. It should be noted that P. platessa, Ammodytidae sp., G. morhua, M. merlangus and C. harengus have been defined as species of importance in the area. This series contains 3 individual reports (1 for each survey period) and GIS shapefiles.

Otter - 30 tows of approximately 20 minutes duration within Tranche B, ten control tows in adjacent areas and 26 tows along the proposed export cable were undertaken. Trawl Sampling. The whole catch from each trawl was retained where possible. Sub-sampling occurred when large (>2 boxes) homogenous samples were obtained. The samples were then boxed, labelled, photographed, iced and stored at +2°C before transportation to Cefas (Lowestoft) for analysis in the middle and at the end of the survey. For the purposes of data analysis, catch rates were calculated to allow for quantitative comparisons made between the numbers of individuals caught per hour at each station. The position of the vessel was tracked at all times using a Garmin GPSMap 278 with an EGNOS differential connected to an external Garmin GA30 antenna. Trawl start times and positions were taken when the winch stopped paying out the gear. Similarly, trawl end times and positions were taken when hauling of the gear commenced. GPS data downloaded and processed in ArcGIS v10.0. File Geodatabases created for each survey type and a feature class generated for trawl (otter, beam), vessel track and catch rates.
