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…
