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 …

This paper researches the effect of two different algae and probiotic treatments as well as a new photonic schedule on O. edulis broodstock with the purpose of determining the best way of conditioning the broodstock among the treatments tested. This was done by answering the research question: What is …

At an aquaponics farm in Luxembourg called “Fësch Haff” the effect of the water quality on the growth rate and behaviour of the rainbow trout has been analysed. Three times a week the water quality in the fish tank expressed by temperature, KH (carbonate hardness), pH, ammonium/ammonia, nitrite, nitrate …

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 …

The growing demand of seafood alternatives is driven by concerns on overfishing, marine pollutants and animal welfare in aquaculture and fisheries. Currently, the availability of non-animal-based seafood flavorings on the market is limited, and animal-based seafood flavorings conflict with vegetarian …

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 …
