That's a good question. I know people do keep them, however they are not listed in the ice fishing regulations. The best thing to do is to call DNR and ask them directly.
I always heard the same thing, Retroboy, but have wondered about it. For instance, sturgeon are not listen in the ice fishing regulations, so by that standard we should be able to keep as many as we want and without size restrictions. However, in the regular season guidelines there is only one month that we cannot target them, and throughout their season the size limits apply. That is why in these instances I always check with DNR or DFO (depending on the situation) for clarification.Tommy cod and any other fish not listed on the ice fishing regulations are non-regulated fish. This means there is no limit on their size or quantity retention in tidal waters. .
Thats true no angler or hunter should waste anything of the fish or game you caught! we should take note from the first natives that use to use everything of them! that way the public couldn't do anything then respect the anglers and fisher!When in doubt , for tidal especially, look at DFO's maritime regulation (link already posted many times on this site). That is all the rules, not just the guide.
Retroboy i'm sure you know this (and of course it was notnyou doing it), but for everyone's benefit, wasting a fish (throwing on the ice or in the woods) is illegal. There is no 'junk' fish and it's all important to the ecosystem. As anglers we are the public stewards of the resource and should be respecting it and ensuring a good example of resource management to others.
If you have a fish who's flesh gets mushy when frying it, try baking instead and it should stay together.
