Preliminary Lake Ontario Alewife Status Report
The preliminary results of the spring 2019 Lake Ontario Alewife Bottom Trawl Survey, conducted annually by the U.S. Geological Survey, DEC and the Ontario Ministry of Natural Resources and Forestry, are now available (PDF). The 2019 alewife survey was the most extensive fish survey ever conducted on Lake Ontario with 252 bottom trawls in the main lake and embayments at depths from 16.5 to 742 feet. Results of the survey indicate that the biomass indices for adult (age 2 and older) yearling (age 1) alewife declined relative to 2018. DEC will hold public meetings later this year to discuss alewife population status and information on Chinook salmon growth and condition.
