I'm pretty sure that this wouldn't really do much, except maybe concentrate even more fishermen on the areas with concurrent salmon season so they can use bait.

The use of bait and/or barbs has been shown to have virtually no effect on adult mortality... even in combination, are very negligible on adults.

In the summer when there are juveniles around, that's a whole different story, as bait and barbs have profound effects on them. Not in March and April, though.

Fish on...
