The sea urchin Diadema antillarum has been cultivated at Van Hall Larenstein University of Applied Sciences HVHL in Leeuwarden in the Netherlands to help restore the coral reefs around Saba and St. Eustatius.

Een wereldprimeur voor onderzoekers van hogeschool Van Hall Larenstein in Leeuwarden: voor het eerst is het gelukt om bijna uitgestorven Tropische zee-egels op structurele basis na te kweken. Het voortbestaan van de diertjes - officiële naam Diadema Antillarum - is van groot belang, want ze moeten het …

Diadema sea-urchins play a vital role in maintaining a balanced coral reef ecosystem by grazing away algae and creating bare substrate for coral recruitment. The RAAKPRO Diadema project aims to develop interventions to improve larval recruitment and juvenile survival to increase local Diadema populations. …

Coral reefs are of great importance for social, biological and economical purposes. However, due to global and local threats they are declining rapidly. One of the ways to sustain coral reefs is sexual coral propagation. While the sexual propagation of corals for reef rehabilitation has been successful …

The main research question of this project was:Which of the four chosen algae is the most suitable for the rearing of Artemia, and ultimately Diadema antillarum larvae, at Van Hall Larenstein University of applied sciences? This question led to several sub questions which could in turn be operationalized …

Coral reefs in the Caribbean have suffered massive losses of corals since the early 1980s due to a wide range of human impacts, such as explosive human populations growth, coastal pollution, global warming, overfishing, invasive species and diseases. The publication in the journal science in 2003 stated …
