i have used cocktail shrimp for salmon and steelhead for many years. try the cooked shrimp that come in the styrofoam trays for shrimp salad and such. i fish em in deep holes were the fish are kegged up and there is not a lot of flow. i use the miniture mash mellows just above the shrimp. both salmon and steelhead love em. i have seen many days that shrimp out fished roe. the fish usually just barely pick up the shrimp, so you really have to watch your rod.
