There seem to be no indigestibles (things like flour, wheat, corn, mainly terrestrial crops, etc.), which is very good.
But it has fish meal which can be bad as it is vague and not the whole fish. "Fish meal" can be used just to name ingredients that came from a fish; essentially, we do not know what part of a fish "fish meal" comes from and it ends up as an unreliable way to determine the quality of fish food.
Fish meal could be the ground up leftovers of a fish, or a fillet from a whole fish
Dried ingredients are generally bad in fish foods as they end up as processed when being made into pellets (the dried kelp).
I do not know much about rosemary extract, but it might be an indigestible.
