Most commercial ( and some home brewed) salmon cures have sodium sulfite in them. Steelhead don't seem to like that as much as salmon do. Hard to beat good old borax for steelhead, salmon will eat borax eggs too.
Go to the bottom of the page and click on Amerman, scroll down and find the page to learn about the different cures, there will be some info that may help you understand some of the different cure theories. Also you may want to pick up or borrow the book on egg curing by Scott Stouder.
well heres the deal, i cured up 10 lbs of eggs with a friends salmon cure. so should i not fish for steelhead with these eggs and just wait for more eggs? if so i'll be getting some amerman steelhead cure.
personally i like a wet cure for salmon where im just lightly casting them with a bobber and shrimp and a more dry cure for steelhead where im casting constantly into faster waters and using small amounts of eggs
