| Sumario: | Global 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. Rotifers and Artemia were good probiotics vectors because S. lalandi larvae fed probiotic supplement showed higher survival that the control. These findings evidence that Pseudoalteromonas sp. are good probiotic candidates for use in S. lalandi larval cultures. However, is needed more research on major scale cultivation to validate their use commercially. |
