What is it about?
This study explored how adding a specific type of cyanobacteria, Oscillatoria sp., affects tilapia farming in saltwater biofloc systems. Biofloc technology is a sustainable way to raise fish, especially where freshwater is scarce, by using beneficial microbes to clean the water and provide extra food. However, cyanobacteria, also known as blue-green algae, can be present in these systems, and their exact impact wasn't well understood. Our research showed that inoculating Oscillatoria sp. significantly influenced key water quality aspects like pH and suspended solids, and importantly, affected how well the tilapia grew, their survival, and how efficiently they converted feed. This highlights the critical need to understand these microscopic organisms to optimize sustainable aquaculture practices.

Why is it important?
This research is important for optimizing sustainable tilapia farming using biofloc technology. It helps us understand the complex microbial environment, manage water quality, and potentially improve fish production efficiently and responsibly.
Perspectives
We need to identify other specific cyanobacteria in biofloc systems and understand if they produce toxins or how they interact with other beneficial microbes. This knowledge could help us develop better management strategies, perhaps even using specific strains to improve system performance or avoid harmful outbreaks, ensuring healthier fish and more productive farms.
