What is it about?

This study investigated whether the type of diet fed to whiteleg shrimp (specifically, how much fishmeal was included) influenced the physical and chemical qualities of the biofloc produced. We collected the biofloc from shrimp cultures, freeze-dried it, and analyzed its nutritional content (like protein, fat, and fiber), particle size, and protein characteristics. Our key finding was that the biofloc's protein content, lipid, fiber, and particle size remained consistent, largely independent of the shrimp's diet. While ash content and protein surface properties showed some variation, the overall nutritional profile was stable. This suggests that biofloc consistently offers high-quality protein, regardless of the feed used, making it a promising and reliable ingredient for animal feed or biotechnological uses.

Why is it important?

This research demonstrates that biofloc from shrimp farms can be a consistent, high-quality protein source, regardless of the shrimp's diet. It supports reducing reliance on fishmeal, improving aquaculture sustainability, and minimizing environmental impact by valorizing waste.

Perspectives

Looking ahead, our study paves the way for using lyophilized biofloc as a valuable protein ingredient in animal feeds, not just for aquaculture but potentially for other livestock. We can further explore its unique compounds for pharmaceutical or industrial applications, turning farm waste into diverse, high-value products and boosting the circular economy within aquaculture.
