This paper researches the effect of two different algae and probiotic treatments as well as a new photonic schedule on O. edulis broodstock with the purpose of determining the best way of conditioning the broodstock among the treatments tested. This was done by answering the research question: What is …

Light is a form of energy produced by a luminous object which occurs as electromagnetic radiation and is closely related to other forms like radio waves, microwaves, gamma rays, infrared, UV and X radiation. The different kinds of radiation can be classified by using wavelengths. Only a small section …

Information about the sources of plastic litter found in the Zeeuwse Delta is still scarce. This problem is addressed by this study with the aim to identify the possible sources of plastics that washed ashore on a selection of beaches in the Zeeuwse Delta. For this study the source and origin of the …

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 …

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 …

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 …

Coastal soft-sediment habitats are some of the most valued ecosystems due to their high productivity, sustaining coastal food webs. However, coastal soft-sediment habitats are under pressure due to human activity and sea level rise. To preserve or restore soft-sediment habitats different management strategies …

The seeding of mussel seeds is an important factor within the mussel culture as losses can be as high as 75% within the first 4 weeks after seeding. Therefore it is important to get more knowledge about the factors that can cause mortality within the first weeks after seeding. With seeding high local …

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. …
