other regions with 2.7ºC-3.3ºC increase by end of century) based on a 3.9°C global warming scenario . In regions where inland fishery production is derived primarily from lakes, there is a lower likelihood of reduced catch, especially where precipitation is projected to increase  . Regions reliant on rivers and floodplains  are more likely to experience downturns in catch, as hydrological dynamics may be altered . Projections suggest that opportunistic species that do well in modified systems  and small pelagic fishes will remain important components of inland fishery food systems . Climate adaptation responses that rely on freshwater resources  represent threats to inland fisheries , by changing flow regimes, reducing water levels, and increasing runoff of pesticides and nutrients .
