The food quality of Tetraselmis suecica slurry for Crassostrea gigas spat

Abstract

L'utilisation de microalgues concentrées et conservées est une des voies envisagées pour améliorer les procédures en écloserie-nurserie de mollusques et en diminuer les coûts de production. Comme elles présentent de bonnes aptitudes à la conservation, les Prasinophycées s'avèrent de bons candidats potentiels. Au cours d'une précédente étude il a été démontré que l'utilisation de Tetraselmis suecica n'était envisageable que chez des larves âgées de Crassostrea gigas. Dans le présent travail, la valeur alimentaire de cette algue fraîche et conservée a donc été recherchée sur des juvéniles de l'huître japonaise. Quel que soit l'assemblage considéré et quelle que soit sa forme, fraîche ou conservée, T. suecica ne permet pas un développement postlarvaire satisfaisant chez C. gigas.

In an attempt to provide cost-effective alternatives to live microalgae and to simplify hatchery-nursery procedures, concentrated microalgae appear to be very promising. Due to its high preservation ability, Prasinophytes appear to be good candidates for such alternative diets. Nevertheless, in a previous study the utilization of Tetraselmis suecica was only conceivable for old Crassostrea gigas larvae. In the present work its nutritional quality has been accordingly searched on ]apanese oyster's juveniles. Whatever the assemblages and condition, fresh or preserved microalgae, T. suecica did not allow an adequate postlarval development in C. gigas.
