Here's what the ISM rule book says:
B.) All Participants must use rod/pole & reel combos or hand held poles. A maximum of 3 rod/pole & reel combos or hand held poles are allowed for each person and a maximum of 2 hooks per rod/pole. This temporary rule expires on January 1, 2013: One rig or lure array for use with multiple artificial baits with not more than TWO hooks. There is also a maximum rod limit of 6 poles per boat (even with 2 members and 1 youth fishing together). The use of rod holders is allowed. Artificial and/or live bait may be used. All crappie must be hooked in the mouth or lips. A landing net may be used and no other types of nets for catching fish are allowed.
Here's what the current state law says:
Hooks for Hand or Pole Fishing
You may fish with no more than three poles or hand lines at any one time. Each line may have no more than two single or multi-barbed hooks, two artificial baits or two harnesses for live bait.
I have been corrected, this rule has expired, so I'm not exactly sure what the rule is. I do know that the main reason the original rule was amended was due to the state allowing the Alabama rig. I can't find any info regarding the Alabama(Umbrella) rig anywhere on the DNR website. The state was allowing the interpretation that an umbrella rig was only one bait, and since you could have two baits per line......then you could have two umbrella rigs per line.
I have spoken with a conservation officer from District 6. The new law concerning the umbrella rig will only allow the use of two hooks per rig. Which clarifies that the umbrella rig is not one bait, but an extension of the line to which you attach a bait.
