Samenvatting

This study has been conducted to estimate the ecological impact of wild harvesting Ulva spp. biomass on its population in the Dutch Wadden Sea. The purpose is to give an advice about the ideal time (on the level of population recovery) to wild harvest 1000 kilogram Ulva spp. from the Dutch Wadden Sea. The study has been conducted in the context of using seaweed as biomass for human and animal consumption, to solve the issue of lack of food availability. This puts the study in a relevant framework, because of its contribution in sustainable development in food availability. In the Dutch Wadden Sea, not much is known about the possibilities and influence of harvesting wild Ulva populations. Besides, at this moment, there is almost no cultivation or wild harvesting present in this area.
