I have used minnow traps in small streams and lake edges in the past with some success however I am having no luck using them in my boat slips this year.

I use a combination of stale bread and dry dog food as bait for the minnows. One of my slips has a green underwater light in it and is about 20' deep. I know there are minnows there as I can watch them swimming around in the green light at night.

I have tried suspending the traps at the bottom of the slip and at the top of the slip. So far I have not caught a single minnow in either trap.

The other slip is in around 12' of water. It has porcupine fish attractors in it and generally has crappie there. I have tried the two minnow traps at the top and bottom of the water there. Same results, have not caught a single minnow in either trap.

Any suggestions as what I am doing wrong or what I could do better?
