Declining fish biodiversity poses risks for human nutrition — ScienceDaily

All fish are not created equal, at least when it comes to nutritional benefits.

This truth has important implications for how declining fish biodiversity can affect human nutrition, according to a computer modeling study led by Cornell and Columbia University researchers.

The study, “Declining Diversity of Wild-Caught Species Puts Dietary Nutrient Supplies at Risk,” published May 28 in Science Advances, focused on the Loreto region of the Peruvian Amazon, where inland fisheries provide a critical source of nutrition for the 800,000 inhabitants.

At the same time, the findings apply to fish biodiversity worldwide, as more than 2 billion people depend on fish as their primary source of animal-derived nutrients.

“Investing in safeguarding biodiversity can deliver both on maintaining ecosystem function and health, and on food security and fisheries sustainability,” said the study’s first…
