Although large quantities of fish larvae are produced by aquaculture industry, survival rates are low or highly variable and growth potential is in most cases not fully exploited, indicating significant a huge gap in our knowledge concerning optimal nutritional conditions. 

Early nutritional modulation with natural digestive promoters during early stages has implications in the modulation of fish gut microbiota signatures, and these microbial signatures may be correlated with high performance phenotypes. The perspective of applying this novel concept to aquaculture industry provides numerous advantages, since digestive capacity is considered key to fish resilience, and therefore to growth and survival. 

PROLAR will provide the scientific foundations for evidence-based recommendations for optimal early metabolic programming in fish that incorporate long-term digestive improvement, and therefore, aquaculture profitability outcomes.
