L'élevage de l'Ormeau (Haliotis tuberculata L.) 1. Action d'un régime alimentaire d'algues phytoplanctoniques sur la croissance post-larvaire

This work tests the action of microalgae at different concentrations on the postlarval growth rate of the abalone Ealiotis tuberaulata from the creeping stage to 60 days,. depending with different kinds of water during the breeding (running water, closed, system, still water). The growth's curves are ajusted with an exponential function. These data were adapted to an experimental hatchery with a view to a big scale production.
