Abstract This study aimed to identify species compositions that use resources more efficiently and recommend management practices for extensive and semi‐intensive pond polyculture by modeling food webs and calculating performance indicators. We monitored 8 polyculture fish ponds managed by fish farmers that had contrasting fish species compositions in ...

Effects of temperature and browning on the functional response of a freshwater top predator
This study explores for the first time how temperature and browning affect the functional response of a freshwater piscivore, the northern pike. The authors find surprisingly weak effects of browning, challenging visual foraging theory. Pike displayed a rare dome‐shaped functional response in cold clear water, potentially driven by seasonal changes in ...
