The Netherlands is dependent on artificial structures for water safety. In addition to water safety the artificial structures also provide habitat for different aquatic species. When designing artificial structures like dikes and breakwaters adjustments can be taken to increase species richness or stimulate …

Dried Tetraselmis chuii biomass has potential as flavoring agent for the development of plant-based seafood alternatives because of its seafood-like aroma and strong umami taste. Depending on the cultivation conditions, microalgae can adapt their metabolism, resulting in a change in biochemical composition. …

Light is a form of energy produced by a luminous object which occurs as electromagnetic radiation and is closely related to other forms like radio waves, microwaves, gamma rays, infrared, UV and X radiation. The different kinds of radiation can be classified by using wavelengths. Only a small section …

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 …

Rhodomonas salina is a microalgal species, belonging to the cryptophytes, and is widely used as aquaculture feed because of its high nutritional profile and phycoerythrin content. This study investigated the effect of pH on the growth, biochemical composition, and taste of R. salina when cultivated on …

Limestone is a sedimentary rock that is composed mostly of calcium carbonate (CaCO3). Limestone is, among many applications, used as a raw material for the manufacture of quicklime. When limestone is heated, the stone calcinates and quicklime is formed. The primary use of quicklime is in the steel and …

The concept of green biorefinery is based on the processing of green biomass into range of innovative products. The basic idea is to use the green biomass in the most optimal way to produce energy and marketable products. Grass silage has versatile properties as raw material for green biorefinery with …

Microalgae can produce a wide range of valuable metabolites such as proteins, lipids and pigments, so they can be used in many ways. For aquaculture industry, microalgae are usually used as live feed because of their high nutritional level. Fry Marine(Vlissingen, NL) is a hatchery for marine feed and …

To increase the yield and quality of aquaculture feed, the effects of N and P concentrations on biomass productivity and cell composition were examined in the marine diatom Skeletonema costatum. Batch-cultured microalgae in Walne’s medium with 3.5 ± 0.5 mmol L-1 N-NO3- and 0.30 ± 0.05 mmol L-1 P-PO43- …

The aquaculture sector is expanding worldwide, which gives this sector an important economic potential. A problem for the on land aquaculture sector is that there is insufficient quality feed for cultivating fish larvae and shellfish. Based on this problem the RAAQUA project was launched (Robust Algae …
