Suckers where going strong in northern wisconsin last weekend.
MOON PHASE (28%)
I say they are done in a week. That is how long they spawned by me, Sun the 9th they were in and sat the 15th they were gone. They probably hang back another week in deeper wholes to recover? Not sure but that is what one told me when they are gone where i fish they hang back in them deep holes then return to where they came from. That is where i fish though, but i say when you see or catch a lot of them with loose eggs and milking they most likely gone in a few days, then back to lake in a week or 10days? No Sucker expert but that is what i have seen.
I used to get them in the tributaries to the Sugar, often in trickles you could jump across. Thread half a worm onto a #6 hook, attach a split shot about 6" up. Dabble in any decent hole, or below obvious riffles where it gets deeper. If it had running water, there were suckers in it; I remember taking 2 out of a tiny creek hole that was literally a foot wide and a foot deep.
Nowadays that stretch of the Sugar is trout water, so there are restrictions. But I'm sure the Yahara and Six Mile have similar stretches with good access.
Fishingmaster, There are some in the Menomonee River by Miller Pork. I have not had any luck getting them to bite but the DNR was there shocking and netting them for tags/size late this am. That method seemed to work well for them but I doubt they'd let us do that.... I'm thinking of heading back with poles this time. Supposed to rain in the am and on Fri, this may be my last chance.
