What is it about?
This study explored how to make shrimp farming more sustainable by reducing fishmeal in their diets, as over-reliance on fishmeal strains wild fish populations. We tested various feeds, some with no fishmeal, for Pacific white shrimp grown in a "biofloc" system. Biofloc technology recycles waste into nutritious natural food. Our findings show that even with significantly less or no fishmeal in the prepared feed, the biofloc system allowed shrimp to maintain excellent growth and nutrient quality, specifically in their amino acid and fatty acid profiles. This means the biofloc itself provided essential nutrients, compensating for the reduced fishmeal.

Why is it important?
This research offers a path towards more sustainable aquaculture. Reducing fishmeal in shrimp diets lessens pressure on wild fish stocks, making food production more environmentally friendly and economically viable.
Perspectives
Our findings contribute to the development of highly sustainable shrimp feeds with minimal reliance on fishmeal. Future work could focus on optimizing plant protein sources and biofloc conditions to further improve shrimp health and growth, expanding its application in low-salinity inland aquaculture worldwide.
