I’d be curious to see if there’s any science behind the difference between animal-based, fish-based and plant-based protein sources in aquaculture. For humans, fish, eggs, poultry, and meat all are considered “complete“ sources of protein because they contain all of the essential amino acids that we need on a daily basis. Things like nuts, lentils and beans are considered “incomplete” sources of protein because they’re lacking one or more essential amino acids.
I think whether your fish food is fish-based or animal-based doesn’t matter as much as it is for animal-based versus plant-based. Your protein is only as good as the amino acids it has in it. Whether that’s true for fish, I’m not sure.
