Smaller fish species are more nutritious, lower in mercury and less susceptible to overfishing, a Cornell University-led research team reveals. They highlight that, when it comes to fishing sustainably and economically, smaller species that are more common and less expensive are also more nutritious and lower in mercury. The team’s study, published in One Earth, was conducted in the Amazon River, but the findings have implications for biodiversity conservation and public health across the globe as large fish species populations decline worldwide.
