Catch per unit effort (CPUE) of Prussian Carp in Saskatchewan Lakes. (A) Relative abundance and (B, C) CPUE for fish species sampled in Coteau Bay by beach seining. The top panel (A) displays relative abundance data for 9 species sampled in Coteau Bay, Lake Diefenbaker. The middle panel (B) displays the full time period sampled; and (C) displays CPUE for each species zoomed into the last half of the summer after the initial emergence of YOY Prussian carp. A reduced species list is visible in B and C because some species were not present or only present in negligible numbers not visible on this scale. First emergence of YOY Prussian carp was on July 6th
