Restoration engineering measures, such as managed realignments or building groins, modify the environmental characteristics of coastal intertidal ecosystems. Creating physical modifications that are beneficial to an intertidal system's ecology necessitates an in-depth understanding of the relationships …

Echinoderm mass mortality events shape marine ecosystems by altering the dynamics among major benthic groups. The sea urchin Diadema antillarum, virtually extirpated in the Caribbean in the early 1980s by an unknown cause, recently experienced another mass mortality beginning in January 2022. We investigated …

Fish assemblages of different types of artificial reefs can differ greatly in abundance, biomass and composition, with some reef types harboring over five times more herbivores than others. It is assumed that higher herbivorous fish abundance results in a higher grazing intensity, affecting the benthic …

The 1983-1984 die-off of the long-spined sea urchin Diadema antillarum stands out as a catastrophic marine event because of its detrimental effects on Caribbean coral reefs. Without the grazing activities of this key herbivore, turf and macroalgae became the dominant benthic group, inhibiting coral recruitment …

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 …

This study originates from an increasing demand for seaweed cultivation. HZ University of Applied Sciences, together with farmers, under the umbrella “Living Lab Schouwen Duiveland” will conduct a field study to assess the possibilities for introducing brown seaweed cultivation at or near existing mussel …

The turbidity in Lake Markermeer limits the primary production by phototrophic algae and the growth of plants. In turn, this limits the amount of fish and other organisms that live in and around Lake Markermeer in its food sources. To determine if there are organisms that limit the resuspension, a survey …

The second Workshop on Tradeoffs Scenarios between the Impact on Seafloor Habitats and Provisions of catch/value (WKTRADE2) was established to provide input on trade-offs aspects to the Working group on Fisheries Benthic Impact and Trade-offs (WGFBIT). As such, the workshop was tasked to: 1) demonstrate …

For multiple reasons, such as changing ocean temperatures, overfishing and unsustainable tourism coral reefs are declining worldwide. A negative feedback loop is created by the loss of three-dimensional structures that the coral reefs create. These three-dimensional structures provide shelters for grazing …

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 …
