Yup, if legal to use for bait of course.
Back east using salmon eggs for trout (steelhead) was often the most productive; a single salmon egg on a # 14 or 16 hook (yeah, that tiny!) at the end of a light leader, progressively weighted to bring the egg down just off bottom, fished under a float - drift fishing in rivers / streams led to lots of great battles with beautiful salmon and trout - chinooks, steelhead, rainbows, browns, even caught a laker that way once

Aw, now I'm sitting here reminiscing!
