The Netherlands is a densely populated and economically developed country. Coastal areas are important for aquaculture, agriculture, harbors, and urban development. Coastal habitats mainly exist on the south Delta coast and the north Wadden sea, hosting a great biological diversity. The Netherlands had …

In de afgelopen jaren is er steeds vaker gezocht naar nieuwe methodes om het klimaat van het verleden te kunnen reconstrueren. Voor temperatuur bepalen wordt er onderzocht of Mg isotoop ratio’s hier een indicator voor kunnen zijn. Het verschil tussen twee isotoop ratio’s wordt uitgedrukt in de delta …

The experimental fishing method of pulse trawling was initially developed to decrease fuel consumption rates of flatfish fisheries in the North Sea targeting common sole (Solea solea). By replacing tickler chains with electrodes, the targeted fish is immobilised until it enters the net by using electrical …

Electric pulse fishing is a very promising and innovative solution instead of using tickler chains such as beam trawling, to enable the catch flat fish. Bottom-trawling activities on the marine ecosystem cause the scrape of the surface or dig into the seabed. The penetration of the gears produce the …

Alzheimer’s disease is the leading cause of dementia affecting over 46 million worldwide, yet contemporary medication is unable to prevent or slow its neurodegeneration. Recently, fucosterol and saringosterol, two phytosterols from brown macroalgae, have emerged as possible mediators of the disease. …

In this study, various extraction methods were compared based on their ability to extract both free amino acids, and free 5’-monophosphate nucleotides from the seaweed Saccharina latissima. Based on the results, extraction at room temperature with Milli-Q over 24 hours was chosen as the method of choice, …

Blue mussels (Mytilus edulis) create niches in the Wadden Sea and therefore they are important for the Wadden Sea. Because there are less mussel beds in the Wadden Sea than would be expected and because of their important role, they are monitored since the mid-nineties. It was found that some beds were …
