I caught the fish on a white tube jig with sucker meat in about 50 fow (just guessing; no fish finder. it was just off of sunset point. I hooked two others but lost them.
Are mysis shrimp about 1/4 to 1/2 inch long, kind of translucent gray/tan and with black eyes? My trout had a stomach packed full of these little guys, along with a big treble hook in its throat, which I found the hard way ouch!
