Aquaculture has emerged as a critical industry for global food security, particularly in regions like Trishal, Mymensingh, where Pangasius farming plays a significant role in local economies. However, the traditional methods of fish farming have limitations in terms of scalability, sustainability, and efficiency.The vertical expansion of existing fish ponds using aquaculture 4.0 technology to enhance fish production two to three times greater.Vertical expansion in aquaculture entails boosting production by maximizing water column space efficiently. Traditional aquaculture systems in Bangladesh have primarily focused on pond-based farming, where fish are cultivated in shallow water bodies. However, with the population increasing and available land decreasing, alternative methods are imperative for sustainable fish production. Vertical expansion in aquaculture in Bangladesh offers various advantages for fish farmers, the environment, and the economy. By diversifying production methods and utilizing innovative technologies, farmers can boost productivity, profitability, and sustainability in the long term.Enter Aquaculture 4.0, a revolution driven by the convergence of Machine-to-Machine (M2M) communication and the Internet of Things (IoT). This technological evolution offers an innovative solution to expand the potential of aquaculture, particularly in vertical pond farming.Vertical expansion enables farmers to optimize fish production per unit area by utilizing water column space more efficaciously, resulting in higher stocking densities, quicker growth rates, and greater yields, thus improving overall productivity and efficiency.
