Analysing the Growth of Biofloc Technology in the Regional Economy of Bangladesh

Purpose. The purpose of the article is to analyse the growth, economic significance, and practical effectiveness of Biofloc Technology in the regional economy of Bangladesh, assessing its contribution to fish production, employment generation, and sustainable aquaculture development. Method. The study applies a descriptive research design supported by secondary data analysis. Economic indicators, cost–benefit assessments, and production efficiency data were examined to compare traditional pond aquaculture with Biofloc-based systems. Comparative evaluation of protein retention, stocking density performance, feed utilisation, and microbial activity was used to assess technological effectiveness. Findings. The results demonstrate that Biofloc Technology significantly increases production efficiency while reducing feed costs, space requirements, and dependence on traditional pond systems. Evidence shows higher survival rates, increased biomass output, improved nitrogen utilisation, and enhanced economic returns. The technology supports youth entrepreneurship, reduces unemployment, and promotes more resilient and sustainable aquaculture in Bangladesh. Theoretical implications. The study strengthens theoretical perspectives on sustainable aquaculture and microbial-based nutrient recycling systems. It confirms that Biofloc Technology aligns with circular-economy principles through “upcycling” waste nitrogen into high-value microbial protein, contributing to ecological sustainability and resource-efficient production models. Practical implications. The findings support the adoption of Biofloc Technology as a cost-effective and highly productive aquaculture method suitable for regions with limited land and water resources. Policy makers and stakeholders may utilise the results to promote entrepreneurship, youth employment, small-scale fish farming, and national strategies oriented toward food security and economic growth.
