This data was derived as part of the Overall Assessment of the State of Nearshore Waters. Sampling block locations and associated consumption advisories were extracted from the Ontario Ministry of Environment, Conservation and Parks Guide to Eating Ontario Fish. The number of meals per month recommended for certain fish species and size classes were summarized based on the average total meals per month. This was used to assign low, moderate or high stress to each Regional Unit.Points represent the centroid of a Regional Unit. An average of -99 indicates that there was no data for that species/size class.Note that some Sampling block locations are used to assess Fish Consumption within more then one Regional Unit. Low Stress: 8 or more meals per month; Moderate Stress: between 1 and 7 meals per month; High Stress: less than 1 meal per monthLAKE ERIE: Smallmouth Bass (size class:20-45 cm), Yellow Perch (size class:20-30 cm) and Walleye (size class: 35-55 cm); Guide Years 2015, 2017LAKE ONTARIO: Northern Pike (size class: 50-70 cm), Yellow Perch (size class: 20-30 cm) and Walleye (size class: 35-55 cm); Guide Years 2015, 2017LAKE SUPERIOR: Lake Trout (size class: 40-70 cm), Lake Whitefish (size class: 40-60 cm) and Yellow Perch (size class: 20-30 cm); Guide Years 2015, 2017, 2020 |
