Larger Fish Upstream: Testing the Drivers of Fish Longitudinal Size Distribution in a Stream

Freshwater Biology, Volume 70, Issue 7, July 2025.
ABSTRACT The “larger fish upstream pattern” (LFUP), where fish size increases from river mouths toward headwaters, is widely documented, but the drivers remain unclear. Here, we tested whether LFUP is related to species reproductive strategies or environmental factors (differential growth, predation, competition). Using historical data (1994–1998) from
