Smart aquaculture, artificial intelligence, costbenefit analysis, machine learning, net present value, water-quality monitoring
AuthorsAbstractSmart aquaculture technologies are gaining traction as solutions to better manage water quality, boost productivity, and enhance the efficiency of investments, but are still hard to quantify in economic value under farm-level uncertainty. This study created an AI based scenario-based cost benefit framework for the assessment of smart aquaculture technologies with the public pond level aquaculture data from Andhra Pradesh, India. The smart aquaculture functions were first categorized as monitoring, management with equipment, advisory decision support, follow-up monitoring, correctiveaction implementation, and self-initiated management. A pond-level analytical dataset was then created by merging water-quality, stocking, harvest, equipment and sensor-campaign data records. Multiple machinelearning models were developed to predict yield, and the best model was integrated into a counterfactual cost-benefit analysis between a ‘business-asusual’ (BAU) and a ‘smart-aquaculture' (SA) scenario. The present net value, benefit-cost ratio, return on investment, payback period, sensitivity analysis and Monte Carlo simulation were used to assess economic feasibility. Extra Trees was the best performing model with an R2 value of 40.5%. The scenario-based framework estimated a median NPV of USD 46,718.91, median BCR of 7.42 and 65.70% economically feasible ponds based on the specified baseline economic assumptions. Analysis of the adoption gap revealed that there was a higher potential for marginal gains where the existing level of smart-technology intensity was lower, which informed targeted investment decisions. The framework provides a decision-support pathway for the assessment of smart aquaculture investment options that can be replicated in other situations with limited data and assumptions.
