Large-scale microalgae production for nursery rearing of marine bivalves OMA
De Pauw, N.; Verboven, J.; Claus, C..
The feasibility of large-scale bloom induction of nutritionally suited natural phytoplankton species, to feed a semi-industrial nursery of edible shellfish, built on the Belgian coast, was tested. The outdoor microalgal production unit consisted of four tanks of 100 m² surface each (two of 1 m depth and two of 0.5 m depth), equipped with different mixing devices. The cultures were run as chemostats in which seawater was enriched with commercial inorganic N, P and Si fertilizers. Depending on the season, between 5-10 and 80% of the culture volume could be harvested daily, with algal densities ranging from 50,000 to 500,000 cells per ml. By manipulation of operational parameters such as detention time, nutrient levels and nutrient ratios (N: Si: P), unsuited...

Maitrise de la culture de masse de la diatomée Skeletonema costatum en système ouvert et continu sur un milieu en "eau de mer" ArchiMer
Brossard, Nicolas; Hussenot, Jerome.
Une culture extérieure en masse de la diatomée Skeletonema costatum, en système ouvert et continu, a été réalisée en automne 1996, au marais expérimental du CREMA I'Houmeau. Le but était d'apporter une nourriture complémentaire aux huîtres en période d'affinage.

New developments in the mass culture and nutritional enrichment of the rotifer <i>Brachionus plicatilis</i> using artificial diets OMA
Komis, A.; Naessens, E.; Van Ballaer, E.; Van Sprang, P.; Léger, P.; Sorgeloos, P..
A research program was carried out to improve and facilitate rotifer (<i>Brachionus plicatilis</i>) culturing as well as to assure their optimal nutritional quality as a prey, concentrating on the development of a dry and complete rotifer diet that does not require the use of algae and does result in a HUFA rich <i>Brachionus</i>. The present poster provides results dealing with culture aspects and rotifer nutritional quality. Different diet compositions based on single cell proteins enriched with various nutritional additives were evaluated. Results obtained so far demonstrate that a selected formula of a combined culture and enrichment diet, that does not involve the use of microalgae at all, can be successfully used for growing...
