It is only with treble hooks that you need to add to make them legal. If you have a single hook you are ok.
I e-mailed the following to the Minnesota DNR:
Are treble hooks legal for use with live bait under a tipup?
I was under the impression that if you had one minnow and you stuck a hook
into it or maybe a single hook and a trebel you had one lure down. I know
you can have two single hooks in the summer on a crawler harness.
According to the below cited excerpt from the 2004 regs I can use three
flies for certain species. Does that include ice angling? can I tip these
flies with bait?
Does the presence of a spinner on the line affect any of this?
From the 2004 regulations:
Angling Methods
* Anglers may use only one hook. An artificial lure is considered one
hook. A treble hook, when not part of an artificial lure, is considered
three hooks and is not legal. The exceptions are: Three artificial flies
may be used when angling for trout, crappie, sunfish, and rock bass.
* Anglers may use only one line. The exceptions are:
a) Two lines may be used through the ice (other than on designated
trout lakes and streams); and b) Two lines may be used on Lake
Superior when more than 100 yards from the point where a tributary
stream or river enters the lake.
Here is the reply I got:
They are if a spinner is attached to the line within 3 inches of the hook. A spinner makes it part of an artificial lure, no spinner, not part of a lure so they can not be used by themselves, there must be a spinner with them.
I made mine like the article in a recent In-Fisherman magazine. First I cut an 18" length of 18# test 7 strand, I added a swivel. I threaded a cleavis and spinner on followed by a small bead. I then threaded on a length of heat shrink tubing followed by a #6 VMC red treble hook. I then heated the tubing to make the treble adjustable. I then fastened the other #6 VMC red treble hook to finish it off.
