Het is al lange tijd één van de belangrijkste vragen in het visonderzoek in de Waddenzee: kunnen vissen ongehinderd van de zoute zee naar het zoete achterland zwemmen en vinden ze dan voldoende plek om zich voort te planten?

The EU Maritime Spatial Planning Directive (MSPD) requires the member states (MS) to pursue Blue Growth while ensuring good environmental status (GES) of sea areas. An ecosystem-based approach (EBA) should be used for the integration of the aims. However, the MSPD does not specify how the MS should arrange …

Coastal and marine cultural heritage (CMCH) is at risk due to its location and its often indefinable value. As these risks are likely to intensify in the future, there is an urgent need to build CMCH resilience. We argue that the current CMCH risk management paradigm narrowly focuses on the present and …

Vorige week organiseerde de Dutch Caribbean Nature Alliance een workshop over het herstel van de zee-egels op Saba. Deze workshop hielp 21 koraalexperts uit het Caribisch gebied en meer dan 65 online aanwezigen om een uitgebreid beeld te krijgen van de algehele situatie van de Diadema zee-egel in het …

In april 2022, the Dutch Caribbean Nature Alliance (DCNA), together with the University of Applied Sciences Van Hall Larenstein, hosted a sea urchin (Diadema Antillarum) restoration workshop on Saba. During the workshop experts and representatives from the Dutch Caribbean and Jamaica came together to …

At Van Hall Larenstein University of Applied Sciences (HVHL) in Leeuwarden, the sea urchin Diadema antillarum has been cultivated to help restore the coral reefs around Saba and St. Eustatius (Caribbean Netherlands). The first young urchins bred in Leeuwarden were released on March 24th to the Rotterdam …

Een tropische zee-egelsoort kan de redder worden van de Caribische koralenriffen. Deze Diadema antillarium is echter zeldzaam en moeilijk te kweken. Bij Hogeschool Van Hall Larenstein lukte het om een continue kweek op te zetten. Tom Wijers is onderzoeker bij het Diadema-project: "Praktijkgericht onderzoek …

The aroma and taste of eight different phototrophic microalgae species were investigated and compared with five seaweeds to evaluate their potential as flavor ingredients in plant-based seafood alternatives. To assess their per- formance, commercial seafood flavoring products were used as a reference …

Diadema sea-urchins play a vital role in maintaining a balanced coral reef ecosystem and their restoration is essential to assist recovery of the degraded coral reefs around Saba and St. Eustatius. A collaborative effort between University of Applied Sciences Van Hall Larenstein, WUR, STENAPA, CNSI and …

The massive die-off of the herbivorous sea urchin Diadema antillarum in 1983 and 1984 resulted in phase shifts on Caribbean coral reefs, where macroalgae replaced coral as the most dominant benthic group. Since then, D. antillarum recovery has been slow to non-existent on most reefs. Studying settlement …
