Declining fish biodiversity in Peruvian Amazon affecting human nutrition
by Liz Kimbrough on 28 May 2021
Declining fish diversity in the Peruvian Amazon could affect nutrition for many of the region’s 800,000 people, according to a new study.
In Loreto region, fishers have been catching fewer large migratory fish species, which are being replaced by smaller fish. Although protein levels are roughly the same, smaller fish contain more omega-3 fatty acids but less iron and zinc, overall an issue in a region where people already have high rates of anemia and malnutrition.
Inland communities are already transitioning toward eating more farmed fish and chicken, but these foods may not be an adequate replacement for the range of nutrients these communities get from a diverse diet of wild fish.
