Het doel van dit onderzoek was om statistisch een benadering te maken van de optimale bodembedekking voor tarbot in de raceways van Seafarm. Het is van belang dat de kweek duurzaam verloopt, zodat het welzijn van de tarbot niet verkeken wordt, maar er moet ook voldoende productie zijn dat de handel winstgevend …

Salt marshes are known to be an important habitat type for numerous species of fish. As fish stocks are pressured around the world, providing them with suitable habitat is very important. Through managed realignments or tidal restoration, intertidal salt marshes are created or restored. Which fish use …

De Japanse oesterboorder (Ocinebrellus inornatus) is een aquatische roofslak die zich voedt met de Japanse oester (Magallana gigas) als de Zeeuwse platte oester (Ostrea edulis). De oesterboorder boort door middel van zijn tong een gaatje in de schelp van de Japanse- en Zeeuwse platte oester en zuigt …

In the following thesis, research is conducted on the effect of sea-level rise and expected hydraulic load levels for the Scheldt Estuary, currently and in the future. As climate changes advances and the sea-level rises, insight into the effects of the rise on our coastal area's is essential. Rijkswaterstaat …

The turbidity in Lake Markermeer limits the primary production by phototrophic algae and the growth of plants. In turn, this limits the amount of fish and other organisms that live in and around Lake Markermeer in its food sources. To determine if there are organisms that limit the resuspension, a survey …

Microalgae can produce a wide range of valuable metabolites such as proteins, lipids and pigments, so they can be used in many ways. For aquaculture industry, microalgae are usually used as live feed because of their high nutritional level. Fry Marine(Vlissingen, NL) is a hatchery for marine feed and …

This study aimed to get more insight into the spatial distribution pattern of the macrobenthos at the Vlakte van de Raan in relation to environmental gradients (median grain size, salinity and bathymetry). 82 samples were collected in November 2016 with a Van Veen grab using the research vessel the ‘RV …

The aquaculture sector is expanding worldwide, which gives this sector an important economic potential. A problem for the on land aquaculture sector is that there is insufficient quality feed for cultivating fish larvae and shellfish. Based on this problem the RAAQUA project was launched (Robust Algae …

From previous research in the western Wadden Sea it is clear that mussel plots are important hotspots for biodiversity. When the density of a mussel plot is higher, the biodiversity appears to be higher as well. This final thesis project was a part of the bigger project, ‘Added value with Mussels’, executed …
