Suckers are 5 star. Back in my day we just fried them in a pan. I like to inspect my fish these days because we have worms in the bass fillets in Florida. We never had worms in our fish up north. I would....

Prepare them like bass ,either fillet or whole.

After soaking them in a salt water solution for a couple of hours ,I would shake them up in a bag with 50/50 corn meal and flower with salt and lots of pepper. Put about 1/2 " of healthy oil in a black pan on med.high heat. Fry to golden brown.Nice tasting fish like white or yellow perch. The roe is also excellent. They fight very good but hard to hook.They nibble very softly.

God Bless,
