I do my best to replicate the diet of the subject. Fresh shrimp is approximately 76% water and crab is roughly 79% water. Once the animals are dried they are approximately 82% protein, 6% fat, 6-1/2% minerals and 5-1/2% water. The high protein is problematic with the ingredients that I found suitable. I contacted a friend and he told me that he could get culled shrimp and grind it into a meal for me. After I got up after hearing the price I realized it wasn't that bad considering fresh shrimp are 76% water. With that in mind this is what I came up with: Ingredients (first to last by dry weight) - Whole Shrimp Meal, Egg Whites, Whole Menhaden Fish Meal, Red Pepper and Paprika 79% Protein, 5.7% Fat, .1% Starch, 6.1% Fiber, 0.1% Sugar. 4.1% Minerals and 4.9% Moisture I plan to buy a couple of lbs from my friend when it becomes available again to make some food for testing. Anyone want to be a Guinea Cephalopod? Since the drying process increases the nutrient levels roughly four times, Would it curb the Cephalopod's insatiable appetite?
