Abstract:Evaluating trends in fisheries, especially data‐limited small‐scale fisheries, is challenging. We used fish landings to evaluate changes in composition of fish landings in rivers of the Central Amazon, from a discontinuous historical 28‐year series of landings from different data collection systems in main ports of the city of Manaus, the largest consumer market in the region. Annual mean trophic level (MTL), fishing‐in‐balance index (FiB), and mean landed size (MSL) were estimated. MTL did not decline, FiB wa… Show more
