The purpose of this research was to answer the question: Have anthropic activities, other than fishing, influenced the decrease in fishery production in the Magdalena River basin between 1980 and 2015? We analysed diverse variables which were used as proxies for different environmental degradation processes: sediment load, forest cover, flow rates, reservoir volume < 1200 m·a·s·l·, gold production and human population growth. We compared these variables with fishery production between 1980 and 2015 using cluster analysis (Bray-Curtis), principal component analysis (PCA) and principal component regression (PCR).
