Effect of rearing conditions on astaxanthin accumulation in the white shrimp Penaeus vannamei (Boone, 1931)
ABSTRACT Astaxanthin is an essential micronutrient that regulates shrimp physiology, acting as a free radical scavenger, increasing stress resistance, and enhancing the immune response, improving growth and survival in farm-raised organisms. Despite this, accumulation of astaxanthin has not been eva...
