Shrimp larvae do not feed like adult shrimp: How three decades of innovation continue to shape larval nutrition

Shrimp larvae undergo rapid morphological and physiological transformations within eight days, changing feeding strategies from herbivorous filter-feeding zoea to predatory mysis and benthic post-larvae (PL). During late mysis metamorphosis, larvae experience an enzyme crisis marked by temporary declines in digestive enzyme activity alongside oxidative and osmotic stress during frequent moulting. Universal larval diets fail to address these dynamic requirements. Tailored larval feeding strategies, such as the microencapsulated FRiPPAK FRESH protocol, provide stage-specific nutrition: algae-rich diets (#1 CAR) for zoea, carnivorous profiles with attractants (#2 CD) for mysis, and highly digestible, slow-sinking particles (#3 CD) for early post-larvae. Incorporating functional nutrients supports cuticle synthesis, antioxidant protection, immune readiness, and osmoregulation. Objective staging tools like the AI-assisted SnappArt 360 S-SENSE enable hatcheries to transition feeds based on biological development rather than fixed calendar days. Commercial hatchery trials in Ecuador demonstrated a 20% increase in harvested tank biomass and reached target PL weight one day earlier, while trials in India showed a 59% increase in body weight and 18% increase in length at PL3, reducing cycle duration by two days.
