Abstract
espanolLa demanda mundial de alimentos aumenta el interes en el desarrollo de la acuicultura. En Chile se estan haciendo esfuerzos significativos para desarrollar el cultivo de Seriola lalandi, debido a la alta demanda de su carne a nivel nacional e internacional. Sin embargo, esta especie plantea dificultades persistentes con respecto a la sobrevivencia de las larvas. El objetivo del presente estudio fue evaluar los efectos de la bacteria Pseudoalteromonas sp. como un suplemento probiotico en el cultivo de larvas de S. lalandi. Para esto, larvas de S. lalandi se alimentaron con rotiferos (Brachionus rotundiformis y Brachionus plicatilis) y Artemia sp. que se cultivaron previamente usando microalgas mezclado con Pseudoalteromonas sp. Rotiferos y artemias fueron buenos vectores de probioticos debido a que las larvas de S. lalandi alimentadas con suplemento probiotico presentaron mayor sobrevivencia y longitud que el control al final del experimento. Estos hallazgos ponen en evidencia que los probioticos de Pseudoalteromonas sp. son buenos candidatos para el uso en cultivos de larvas de S. lalandi. Sin embargo, se necesita mas investigacion en una escala de cultivo mayor para validar su uso a nivel comercial. EnglishGlobal demand for food increases the interest in develop of aquaculture. Significant efforts are being made in Chile to develop Seriola lalandi culture, because of the high demand of this fish meat at national and international level. However, this species poses persisting difficulties regarding larval survival. The objective of the present study was to evaluate the effects of Pseudoalteromonas sp. bacteria as a probiotic supplement on the larval culturing of S. lalandi. For this, S. lalandi larvae were fed rotifers (Brachionus rotundiformis and Brachionus plicatilis) and Artemia sp. that were previously cultured using microalgae mixed with Pseudoalteromonas sp.
