Seafarm B.V. is de enige tarbotkwekerij in Nederland en is verantwoordelijk voor ongeveer 1% (100 ton) van de Europese productie van tarbot op jaarbasis (FEAP, 2014a; Seafarm, 2019). Het begin van het kweekproces tot en met de juveniele fase wordt uitgevoerd door het naastliggende bedrijf, Fry Marine. …

This research was conducted as a part of the bachelor program of Delta Management at the HZ University of applied sciences in Middelburg, The Netherlands. Collaborating with the Can Tho University in Can Tho, Vietnam. As a part of an ongoing efforts to limit floating macro plastic pollution. This research …

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 …

In light of recent developments of the onboard ballast water treatment, WMR has developed a new protocol for the assessment of ecotoxicological effects and aims to use it as a standardised test. This study looks into the validation of this short-chronic ELS fish toxicity test, by use of the embryonic …

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 …

Voor het verduurzamen van ontwerpen in de waterbouw komt steeds meer aandacht. Breuksteenconstructies lenen zich hier uitstekend voor. Op ecologisch gebied is informatie beschikbaar over het ecologisch verrijken van breuksteenconstructies door het toevoegen van verschillende materialen. Over de stabiliteit …

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 …

To increase the yield and quality of aquaculture feed, the effects of N and P concentrations on biomass productivity and cell composition were examined in the marine diatom Skeletonema costatum. Batch-cultured microalgae in Walne’s medium with 3.5 ± 0.5 mmol L-1 N-NO3- and 0.30 ± 0.05 mmol L-1 P-PO43- …
