Hi mplspug – I seine some of my better bullhead spots, usually early in the spring. You were right about needing to know the regulations because you can get in trouble pretty easily with some of the complexities in the Minnesota regulations. You already have some of the information wrong in your post and you may want to revisit the regulation booklet. For instance:
– You can have up to 24 dozen minnows for your own use without a permit (that is 288 minnows).
– Pay special attention to the invasive species information. The regulation on page 67 specifically states: “It is unlawful to harvest minnows, frogs, crayfish or any other wild animals from infested waters* for bait, except for personal use from waters that are designated as infested waters solely because they contain Eurasian watermilfoil. Bait may only be harvested from those infested waters for personal use with a cylindrical minnow trap not exceeding 16 inches in diameter and 32 inches in length and the bait may only be used in that waterbody. What all that means is this:
#1. If the water is infested with anything else besides Eurasian watermilfoil you cannot harvest bait from it. This applies to the St Croix River, the Mississippi River below St Anthony Falls, and a host of other lakes and streams listed on page 69.
#2. You cannot seine in infested waters. You can only use a cylindrical minnow trap.
I recommend you thoroughly understand the 2006 Minnesota Fishing Regulations concentrating on the following pages:
Pages 66 to 67: Invasive Species
Pages 68 to 69: MN Waters Infested with Invasive Species
Page 70: Minnows and Leeches
I still seine but I am careful that I know the water I am in is not infested waters. Seining seems to work good early in the spring. Once the water warms up I prefer to catch my bullheads with hook and line – it is more fun that way. I maintain a bait tank with between 50 and 75 bullheads through the summer.
