What is it about?
This study explores a sustainable way to raise whiteleg shrimp (Litopenaeus vannamei) by using less fishmeal in their diets, especially in low-salinity water. Fishmeal is expensive and its supply is limited, so finding alternatives is crucial for the industry. We tested a system called "biofloc technology," where beneficial microorganisms grow in the water and serve as natural food for shrimp. Our research found that even with significantly reduced or no fishmeal (replaced by plant-based proteins), shrimp growth and survival were just as good as with traditional diets. The biofloc system also kept the water clean and actually improved the shrimp's digestion by boosting their enzyme activity. This means we can produce healthy shrimp more affordably and environmentally friendly.

Why is it important?
This research provides a sustainable path for shrimp aquaculture by reducing reliance on fishmeal, lowering costs, and improving environmental impact through biofloc technology.
Perspectives
Our study paves the way for commercial implementation of low-fishmeal diets in biofloc systems, especially in regions with limited access to saline water. Future work could optimize specific plant protein blends and biofloc management for different life stages of shrimp, potentially expanding this sustainable approach to other aquaculture species.
