Description
Sotoudeh and colleagues tested in 2026 protein restriction schedules for whiteleg shrimp, a major farmed species, asking how far daily protein can be cut without harming the animals. Over eight weeks, young shrimp starting near two grams ate rotating diets with high, medium, or low protein shares. The team tracked growth, feed use, digestion enzymes, blood measures, antioxidant defence, and immune gene activity across the schedules.
Sotoudeh found one schedule worked cleanly: one day on the high protein feed followed by two days on the medium feed. Growth, feed efficiency, digestion, immunity, and antioxidant defence all held up on that cycle. Groups pushed to the lowest protein level, alone or in rotation, grew worse and showed weaker flesh quality and health. Their key protein-cutting enzyme dropped, and two immune genes quieted. The authors set the low level as simply too little for this species.
