In developing countries like Colombia, most of the food used in the different stages of fish farming production is imported. These foods have a high ecological footprint since they include phosphorus, potassium and nitrogen salts, as well as medicines for disease control, causing strong impacts to water sources through eutrophication processes. Additionally, the associated costs of these inputs represent between 50-60% of the total production costs for fish farmers. To improve the competitiveness of the fish chain in Colombia, and especially Antioquia, a biotechnological process to produce Spirulina microalgae was designed and implemented, as a raw material for feeding fish, creating a new industry. The process developed a prototype that reduces operating costs u... view more»
