2003

The Dutch Government has decided to allow the construction of a Near Shore Wind Farm (NSW) demonstration project under the condition that a monitoring programme on - among other things - the ecological impacts is carried out. The Dutch government is responsible for providing a thorough description of the present ecological situation in order to evaluate future effects of planned wind farms. The Netherlands Institute for Fisheries Research is responsible for the baseline study on pelagic fish. Within this study, the pelagic fish community was sampled twice in 2003. It was sampled with a high spatial resolution in the planned location of the wind farm and in two reference sites, and with a low spatial resolution in a larger area along the coast. The first fieldwork report was published in July 2003. The present report describes the second survey that was carried out in September/October 2003. It reports on the execution of the monitoring programme, including a description of the circumstances (days, weather conditions, specific situations, etc.), facilities and materials used, and other relevant information. It also describes preliminary results on the occurrence of species and sizes. It does not, however, contain information on biological data, and densities and biomass data per age and sex because this information will be delivered at the end of the second phase of the project. Finally, the progress of the project is discussed. Apart from some minor problems, the survey was executed well. The preliminary results of the present survey are compared to the results of the spring survey.
