Bait shops were out of minnows last week. I was told that minnows are hard to net during a full moon so we purchased a container of frozen minnows, salted. Many were very small.
Perched Sandusky Bay off the Cedar Point Millennium coaster using a spreader and #6 hooks, just off the bottom. Baited one hook with a piece of night crawler and the other hook with a minnow. Double hooked the minnow as they were a bit mushy.
Caught only 6 keeper perch and about 30 throw-backs. I'd estimate that about 70% of the perch caught preferred the minnows over the crawlers. It was a very light bite and I did lose some minnows but frozen minnows were definitely better than no minnows.
I'd recommend using frozen minnows only as a back-up to fresh minnows.
