I am here. HSB do not require high protein diets and can digest carbs well. BG and LMB do not use/digest carbs so they are different. There is a lot of aquaculture data on HSB food requirements as they are a commercial food source fish (grow out for food consumption by people). 32% protein is plenty and it looks like much of the fish meal requirement can be replaced with soy products. James pm me an email and I will send you the referenced studies.

See this for info.
