Abstract

Colombian fish farming is a rapidly growing sector, crucial for food security and the national economy, generating a significant number of direct and indirect jobs. However, its sustainable development is threatened by its high dependence on fossil fuels to meet energy demands, which can account for up to 40% of operational costs, primarily to maintain optimal pond conditions, with oxygenation being the most critical parameter. This article analyzes the integration of solar photovoltaic (PV) energy systems as a viable and sustainable solution to the energy challenges of aquaculture. Known as aquavoltaic systems, they not only provide clean and economically competitive energy but also drive the sector's digitalization by enabling real-time water quality monitoring. This allows for precise control of dissolved oxygen levels, reducing fish mortality, improving yields, and minimizing environmental impact by avoiding CO₂ emissions. Although it is acknowledged that panel manufacturing has environmental impacts, these are significantly lower compared to the continuous damage caused by fossil fuels. It is concluded that synergy between public policy and private investment is essential to promote the adoption of this technology and consolidate sustainable growth for Colombian aquaculture.
