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? <br>We analysed diverse variables which were used as proxies for different environmental degradation processes: sediment load, forest cover, flow rates, reservoir volume &lt; 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).
