Good discussion topic. ""Protein in excess of 40% is passed by the fish."" Why is this true and is it always true for every protein type and fish species? Different fish species have proven to have significantly different nutrition requirements. It is true for all fish or certain species or types of fish?
Not all proteins (amino acid composition) are the same and probably some proteins have better digestibility - depending. Some proteins are highly indigestible. I think some of your comments above are schooled generalizations and are not complete truisms. A lot of them are probably "it all depends". Depends on the fish species, type or quality of food compound. and the way the food is processed which can affect the digestibility, usefulness as a nutrient and probably several other factors.
