The sale of steelhead eggs is also illegal in Pennsylvania, but there are local shops by Elk Creek (Erie area) where one can make a donation and get bag of skein. I have not found any shops in Ohio that offer the same service.
In my experience, nothing beats fresh steelhead eggs for bait. I've made a number of trips to Erie, PA on Friday nights such that I could get a bag of fresh skein to tie egg sacs to be used for fishing the next morning. I would much prefer to visit a local Ohio shop such that I could sleep in my own bed on Friday night rather than getting hotel in Erie.
ZT - thanks for the tip on Rodmakers. I'll check them out. I thought that they made sacs using salmon eggs. I have had some success using salmon eggs, but I only use them when I can't get my hands on fresh steelhead eggs.
