What is it about?
This study explores how adding specific beneficial bacteria can dramatically improve shrimp farming in "biofloc" systems. Biofloc is an eco-friendly method where microscopic communities clean the water and provide extra food for shrimp, reducing the need for water exchange. We tested two types of bacteria: "nitrifying bacteria" to detoxify harmful waste like ammonia, and Lactobacillus rhamnosus (a probiotic, like those in yogurt) in the feed. Our results show that these additions significantly enhance water quality, boost shrimp growth and survival, and even improve the nutritional content of the shrimp, all while keeping the farming system sustainable.

Why is it important?
This research offers practical, sustainable solutions for intensive shrimp farming. By improving water quality and shrimp performance with beneficial bacteria, we can achieve higher yields and healthier shrimp while reducing environmental impact.
Perspectives
Looking ahead, we aim to delve deeper into the specific bacterial communities to optimize their effects. Future studies could explore different probiotic strains, longer cultivation periods, and larger-scale applications to fine-tune these bacterial interventions for even greater efficiency and disease prevention in commercial shrimp farms.
