Morphometric, hydrologic, and land use characteristics of eight Lake Ontario embayments. Annual total phosphorus load and water residence time were estimated from monthly data provided by X. Chen (unpublished data). Int = intermittent; Perm = permanent; Ssnl = seasonal; Trib = tributary; Wet = wetland.

Embayment characteristics, 2001 – 2003. Ranges (minimum and maximum) of values for mean station depth, percent vegetation, and secchi depth for each year. Species diversity (Simpson's diversity index) was calculated based on all individuals captured during July 2001–2003. Annual piscivore biomass (BPUE) was calculated for all piscivorous species. Quadratic equation r2 values for maximum biomass weight class (h) estimates are shown in parentheses.

2001 – 2003 catch per unit effort and biomass per unit effort means and standard errors for each focal species, all non-focal species combined, and all species combined. CPUE (#·min-1) and BPUE (g·min-1) means and standard errors based on annual estimates for each embayment. Annual estimates were calculated as the sum of the number and biomass of fishes collected at all stations divided by the sum of the effort at all stations.
