A new study published in the Egyptian Journal of Aquatic Biology & Fisheries (2025) highlights the effectiveness of probiotics in enhancing the growth and feed efficiency of snakehead fish (Channa striata) cultivated in a bucket system. This innovative aquaculture method addresses land scarcity by using small-scale media, making fish farming more accessible and environmentally friendly. Researchers tested various probiotic concentrations in feed, finding that a 5 ml.kg⁻¹ dosage was already sufficient to significantly improve growth performance and feed efficiency compared to control groups.
The findings show that probiotics can help fish utilize nutrients more effectively, leading to better growth rates and improved water quality through reduced ammonia levels. Interestingly, survival rates remained consistently high across treatments, suggesting that probiotics primarily enhance growth rather than survival. These results provide practical insights for cost-effective fish farming, supporting sustainable aquaculture practices that contribute to the UN Sustainable Development Goals (SDG 2 – Zero Hunger, SDG 12 – Responsible Consumption and Production, SDG 14 – Life Below Water).
