Papaya (Carica papaya) contains proteolytic enzymes such as papain and chymopapain, which aid in protein digestion and nutrient assimilation. It is also a source of vitamin A, C, E, and flavonoids. In shrimp, papaya supplementation enhances feed efficiency, accelerates growth, and contributes to stronger moults. The bioactive compounds also exhibit antibacterial activity against Vibrio spp.
