Fishers' ecological knowledge points to fishing‐induced changes in the Peruvian Amazon

Ecological Applications, Volume 34, Issue 5, July 2024.
Abstract Scientists increasingly draw on fishers' ecological knowledge (FEK) to gain a better understanding of fish biology and ecology, and inform options for fisheries management. We report on a study of FEK among fishers along the Lower Ucayali River in Peru, a region of exceptional productivity and diversity, which is also a major supplier of fish ...
