Greg,
I have no specific recipe. I try to mix salmon and shrimp at a 60:40 to 50:50 ratio. To that I add various other ingredients like some squid, clams, mussels, cod, etc., along with some flake, freeze dried krill or ocean plankton, and/or ground pellets. I include a green vegetable of some sort and even a odd piece or two of fruit.I also add crushed or liquid vitamins, B complex and C in particular. To my fry mix I also add some ground oyster shell tablets that I get at Fred Meyer's Nutrition for some extra calcium since our water out here is so soft.
