Well said Aaron and your post made me realize a particular fact which as far as I know has never been mentioned in any of these tiresome discussions.
I use roe quite often myself, and like you may not have to harvest a fish this year because I already have enough.
Why? Simply put because I don't chum. The biggest problem most here have with roe harvesting is the indiscriminate slaughter of salmon every fall.
Seeing dozens upon dozens of fish with slit bellies along the banks does nothing good to promote the use of roe as bait.
Who actually needs or uses this much roe? Well, there's two culprits at work here. One, the lowlifes who harvest mass quantities for ilicit sale, and two the guys who constantly throw gallons of chum into a hole attempting to induce a hit.
While I'm not against chumming, the way most of these knobs do it is ridiculous.
If you think there's 6 fish in a hole, throw 5 eggs, not half a gallon.
In any case I neither chum nor sell roe illegally and I'd hazzard a guess that most roe users don't either.
