[EN] La producción de fitoplancton en los centros de cultivo de bivalvos es imprescindible para su utilización como alimento vivo en todo el criadero, desde la llegada de los progenitores a los cultivos larvarios y postlarvarios que se realizan en él. Sin embargo, el cultivo de fitoplancton es una opción costosa además de laboriosa, por ello, el objetivo de este estudio es investigar cuál de las tres especies de microalgas utilizadas habitualmente en el CIMA de Ribadeo como alimentación larvaria de los cultivos de bivalvos (Isochrysis galbana, Chaetoceros muelleri y Pavlova lutheri), es susceptible de ser eliminada en la dieta de la almeja babosa (Venerupis pullastra) desde los primeros estadíos larvarios hasta los 30 días de cultivo. Para ello se ha realizado una experiencia de cultivo larvario de esta especie en tanques de 50 litros. Se probaron 9 dietas, con una réplica cada una, con diferentes proporciones de las tres microalgas
[EN] It is fundamental for phytoplankton production in bivalve cultivation centres to be used as live feed in broodstock, larval and post-larval stages. Nevertheless, phytoplankton cultivation is an expensive and laborious undertaking. Thus, the aim of this study is to investigate which of the three microalgae species usually used in hatchery facilities (Isochrysis galbana, Chaetoceros muelleri and Pavlova lutheri) at CIMA (Centro de Investigaciones Marinas) in Ribadeo, is susceptible to elimination from the diet of the Venerupis pullastra from early larval stages up to 30 days cultivation. To this end, a larvae cultivation experiment for this species was carried out in cultivation tanks of 50 litres. 9 diets were tested with one replica each, and different proportions of the three microalgae species were used
