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 ...

Transferrin polymorphism in Central Amazon populations of pescada, Plagioscion squamosissimus.
Genetics and molecular research : GMR, 2004 Blood plasma of 253 specimens from eight population samples of the sciaenid fish, pescada (Plagioscion squamosissimus), caught from four sites in the Central Amazon, was tested for molecular variants of transferrin. Starch gel electrophoresis was used to distinguish six species of transferrin molecules; 12 of the 21 theoretically possible genotypes ...
