Question and Answer


I just read your article quoting data researched from 2006-2010 in the Lake Simcoe Living magazine. This was seven years ago and I just wanted to know if any research is ongoing and if fish stocking is taking place. I have heard stories of the abundance of Comordants decimating the young bass and many of my fishing friends are having trouble catching anything of late.


Hi Paul,

Thanks for your email.

YES!  There is a lot of research and monitoring going on with Lake Simcoe. In fact, thanks to the Lake Simcoe Protection Plan and Act- extra funds have been allocated for several years now on a wide variety of projects. Additionally MNRF’s Lake Simcoe Fisheries Assessment Unit – located right on the water out of Sibalds Point Provincial Park, has been monitoring and researching the fish of the lake for many decades now.  They have on-the water programs that provide trend thru time data that enables fishery managers with both the Aurora and Midhurst District MNRF offices important data that helps them manage the fisheries … make regulation changes when required, stocking assessments and so on. 

MNRF still stocks 140,000 whitefish and 40,000 lake trout into the lake every year.  Additionally the Lake Simcoe Muskie Restoration Program stocks muskie into the lake every fall to try and bring that species back.

Although cormorants are opportunistic feeders that will pretty well prey on whatever fish they can capture and swallow … some studies are revealing that round gobies have become a major part of their diet … and goodness knows Simcoe has plenty of those.

As for bass … sure there are times when they can be a tough nut to crack on Simcoe … as it is an ever changing lake and anglers need to adapt to even have a hope of keeping up. Simcoe is still a remarkable trophy bass lake though and recognized as one of the most likely places in North America to catch your personal best biggest smallmouth ever!  It can take a lot of work and time on the water with many poor days mixed in in order to experience remarkable catches… just the way it is with this lake since all the changes brought on by Invasive species like round goby, zebra and quagga mussels and even development increases around the lake. 

Hope this helps somewhat Paul and that you have a good season on Lake Simcoe or wherever you wet a line.
