Abstract

Experimentos de mantenimiento del ostión europeo (Orrrr~a edufis) en condiciones de laboratorio.Maintenance experiment of the european oyster (Ostia edulis) under laboratory conditions.Ciencias Marinas 12(3): 70 -81; 1986.RESUMEN Se efectuaron siete experimentos secuenciales con ostiones europeos para conocer la respuesta a un tratamiento de mantenimiento en condicionesde laboratorio durante 250 dfas.Se estableció que a trav6s de la duración del tratamiento con las condiciones ofrecidas a los organismos con alimento vivo en forma de microalga (Tetmselmis suecica) a una concentración constante de 10 x 103 cel/ml y un suplemento de carbohidratos (almidón de malz) a una concentración de 2 ppm, se logr6 un aumento significativo en su peso con respecto a su peso medio inicial.Se detectó que la población en laboratorio no presentó las fluctuaciones registradas por los organismos mantenidos como control en condiciones de cultivo en el medio natural. ABSTRACTSeven sequentials experiments were carried out with European oysters to see how they respond to a maintenance treatment under laboratoty conditions during 250 days.It was established that during the treatment under the conditions given to the organisms fed with live food in microalgae form (Tetraselmis suecica) in a constant concentration of 10 x ld cel/ml and a carbohydrated supplement (com starch) in a concentration of 2 ppm, a significant increase in their weight in relation with their average weight was obtained.It was detected that population in laboratories did not present the fluctuations registered in the organisms maintened in their natural element.
