Shellfish are a healthy source of protein but more strict regulation for traditional shellfish fisheries and fluctuations in population size warrant a need for sustainable and more reliable alternatives. These alternatives can be, for example, the culturing of new species like hard clam (Mercenaria mercenaria). …

Knowledge on the biodiversity and abundance of phytoplankton is key for many ecological and societal (e.g., blue growth) questions. Gathering temporal variation and spatial patterns on key indicators requires reliable and standardized protocols on sampling, species identification and counting. Numerous …

Shipping activities are increasing with sea ice receding in the Arctic, leading to higher risks of accidents and oil spills. Because Arctic toxicity data are limited, oil spill risk assessments for the Arctic are challenging to conduct. In the present study, we tested if acute oil toxicity metrics obtained …

A bottleneck in restoring self-sustaining beds of the European oyster (Ostrea edulis) is the successful development and settlement of larvae to bottom habitats. These processes are largely governed by temperature but a mechanistic understanding of larval performance across ecologically relevant temperatures …

Aggregation into groups may affect performance of individuals through the balance and strength of facilitative versus competitive interactions. We studied in situ how seasonal variation in abiotic environment affects this balance for blue mussels, a semi-sessile species. We hypothesize that seasonal …

Om verzekerd te zijn van voldoende broed van uniform formaat wordt voor de off-bottomkweek van Creusen (Crassostrea gigas ofwel Japanse oesters) in de Oosterschelde het broed doorgaans ingekocht bij broedhuizen in Frankrijk, ook wel hatcheries genoemd. Het inkopen van broed uit Frankrijk en het daarna …

De productie van mosselen loopt inmiddels al jaren terug. De mosselkweker moet heel wat hordes nemen voordat de mosselen geleverd kunnen worden aan de Nederlandse mosselveiling. De meeste mosselen worden verkocht aan België, Duitsland en een klein deel aan Frankrijk. Met de stijgende kosten voor materialen …

Forecasting long-term consequences of global warming requires knowledge on thermal mortality and how heat stress interacts with other environmental stressors on different timescales. Here, we describe a flexible analytical framework to forecast mortality risks by combining laboratory measurements on …

Native (flat) oyster (Ostrea edulis) beds, once a major component of the North Sea, largely disappeared from the region in the late 19th century. Flat oyster restoration is taking place at a number of locations in the North Sea. When flat oyster beds are restored in areas where O. edulis is functionally …

Om Creuse en platte oesters te kunnen kweken zijn jonge oesters ('oesterbroed') nodig. Oesterbroed wordt verkregen door het invangen van oesterlarven. Traditioneel leggen oesterkwekers hiervoor lege mosselschelpen op de bodem van hun percelen. Er worden ook proeven gedaan met invangmateriaal dat vrij …
