Ok, bare with me, this could get a bit lengthy; I will start with the question, then proceed with my theory. Has anyone ever put a whole minnow on the front hook of a jigging rap, preferably one of the larger jigging raps?
This would be to target walleye or northern. Now on with my theory; I’ve noticed at times when reeling fish in, sometimes a much bigger pike is following. This would explain why sometimes a pike grabs a smaller fish that’s being reeled in.
I think to some degree, either pike are territorial and why small pike tend to swim away fast after grabbing your bait. I noticed bigger pike swim off much slower. Or, fish are at a slight disadvantage for a short period of time when a fish is in its mouth, so a larger one will come in and target the fish, either the fish drops the bait so it can get away, or that fish is now easier to grab.
I saw this first hand the very first time I went spearing. I had a small plastic northern decoy and a sucker in a harness, but not a decoy sized sucker, just a medium sized one. I had the sucker about 3′ down, and once when I pulled up on the northern decoy, it circled and bumped the sucker head on. Immediately, a northern came in and grabbed the decoy. By the time I was getting ready to spear him, he dropped the decoy and swam off. I had not seen the northern prior to this happening. I don’t know if he was waiting in the wings, or just happened to be coming by, but that minnow nudge grabbed his attention.
A couple years ago when I took spearing up again, I wanted to convert or make a northern decoy that I could somehow put a minnow in the front of it, or in its mouth. But I made a golf ball spinner and that worked great for bringing in curious fish.
It wasn’t until last night when I got home from a two day excursion on the lake, that I realized, jigging raps have a hook on the nose, and while sorting through all my tackle on the lake, I noticed I have one of the large jigging raps, which is about 4″ long. I didn’t catch a single fish, but I was near cribs and there were walleye, northerns, bass and even musky, coming by all times of the day. There were panfish as well, but I wasn’t targeting them. I did have encounters with the bass, walleye and northern, but they were obviously pressured. This was both with live bait and jigging raps, with and without heads.
I think a jigging rap with a small minnow on the front hook would trigger that attack instinct. I would probably use a fat head on the big rap for northern and a crappie minnow on a #5. The struggling minnow would be all the action needed. BTW, I already put a 40lb floro leader on the big rap. I already tested the big rap with a dead crappie minnow and it only dips forward slightly. If a fat head is too heavy, I may put a small sinker on the rear hook.
Lastly, I haven’t given up on my much larger sized invention for big pike and larger bait. I may modify one of my giant Chubby Darters with a large hook in the nose, instead of a clip, which I was originally thinking. I was even thinking of adding a stinger hook, attached to the center hook post so I could add a small treble hooked to the minnow. I would remove the rear treble on the darter and replace it with a small bell sinker.
