Metadata: 2012, Royal Hakoning DHV, Thanet Offshore Wind Farm, Post-construction Survey: Fish and Epi-benthic
Abstract:
The following report details the findings of the spring 2012 adult and juvenile fish and epi-benthic survey, undertaken within and adjacent to the operational Thanet offshore wind farm between the 11th and 13th April. The survey methodology, vessel and sampling gear detailed was agreed in consultation with Cefas. The sampling locations are in line with those in the 2005 pre-construction surveys, although it was agreed that a number of positions required relocation for health and safety reasons, due to inter-array and export cable interactions. These were approved by Cefas, as they are within a 100-900m range of the original sampling position. Appendix 1 details the trawls that required relocation, the distance and direction moved and the reason for relocation. A dispensation from the Marine Management Organisation (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. A derogation from Kent and Essex Inshore Fisheries and Conservation Authorities (KEIFCA) for the survey was also received. A summary of the Health and Safety performance of the survey is provided in Appendix 2. The aim of the survey was to establish the abundance and composition of adult and juvenile fish and epi-benthic species within the area, and to determine whether there are any differences between the results of the pre-construction and post-construction surveys.

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | This metadata file was created by The Crown Estate for the purpose of publishing the data to the Marine data Exchange. The proposed scope of works for the April 2012 adult and juvenile fish, and epibenthic survey are detailed below and illustrated in Figure 3.1 and Figure 3.2 overleaf. o Otter Trawl: ? Seven tows of approximately 20 minutes duration within the Thanet offshore wind farm and thirteen control tows in adjacent areas. o Otter Trawl Sample Analysis: ? Number of individuals and catch rate by species; ? Sex ratio by species; ? Spawning condition; o Finfish species (except herring & mackerel): Cefas Standard Maturity Key - Five Stage; o Herring: Cefas Herring Maturity Key – Nine Stage; o Mackerel: Cefas Mackerel Maturity Key – Six Stage; and o Ray and shark species: Cefas Standard Elasmobranch Maturity Key- Four Stage. ? Average length and length distribution by species; o Finfish & sharks: individual lengths (nearest cm below); o Rays: individual lengths and wing-width (nearest cm below); |
