| Objectives | 1. To conduct surveys of Nephrops burrow densities on the Farn Deeps Nephrops grounds, 55° 35' - 54° 45' N and 1° 30' - 0° 40' W, by underwater TV to: i) examine spatial patterns in the distribution of burrows at different spatial scales and to measure variance for replicated counts, by replicating three times ten different clusters of six stations each; ii) evaluate Nethrops abundance for comparison with previous years by surveying the remaining main stations used to evaluate the fishery on an annual basis; iii) to sample all remaining stations previously sampled in any Nephrops TV survey.
2. To backup the TV survey with a QTC survey to establish the ground type. 3. Possible collection of sediment samples by Day grab at selected stations to establish ground proofing for QTC. |
