Canadarago Lake netting (2008)
The 2008 biannual netting of the 1,900 acre Canadarago Lake was completed in September. This sampling effort involves setting two 150 ft long monofilament gill nets overnight each month from June through September. The objective of this study is to monitor the abundance of walleye and yellow perch. Although the catch of 12.8 walleye/net indicates an abundant population, it represents a 41% decline from the record 21.6 fish/net recorded in 2003. The decline may be related to the growing alewife population in the lake. Since first discovered in the lake in 1999, the alewife catch has increased 5,633% to the 16.9 alewife/net recorded this year, an increase of 282% since 2006. Additional data analysis will be required to determine if the growing alewife population is responsible for the decline in walleye abundance since 2003. If the alewife population continues to expand, it is expected that a walleye stocking program will need to be initiated to maintain the high quality walleye fishery in this lake. The catch of 99.3 yellow perch/net is the third highest catch on record for the 14 nettings conducted since 1983. The abundant population suggests that the 2008/09 winter ice fishery for this species should be excellent.
