Over het archief
Het OWA, het open archief van het Waterbouwkundig Laboratorium heeft tot doel alle vrij toegankelijke onderzoeksresultaten van dit instituut in digitale vorm aan te bieden. Op die manier wil het de zichtbaarheid, verspreiding en gebruik van deze onderzoeksresultaten, alsook de wetenschappelijke communicatie maximaal bevorderen.
Dit archief wordt uitgebouwd en beheerd volgens de principes van de Open Access Movement, en het daaruit ontstane Open Archives Initiative.

| Abstract |
The foundations of windmills act as secondary artificial reefs, attracting different kind of fish species. This monitoring aims to determine attraction and/or net production of the ichthyofauna on the artificial hard substrates of the wind turbines placed at the Thorntonbank. By answering specific research questions and integrating the results, the principal question “ Do the secondary artificial reefs only attract fishes or do they produce them? “ can be tackled. A wide fan of technologies will be used in this research. The ichthyofauna associated with the artificial reefs will be quantified using visual and destructive methods, for instance visual census with scuba divers, ROV underwater camera, hook and lines, gill nets and trammel nets. The functional relations between the ichthyofauna and the reef habitat have their influence on growth patterns and productivity. By integrating the techniques and linking the results it will be possible to (partly) unravel and visualize the attraction/production at the artificial reefs in the BPNS. |
