the small fish produce 1 oil each
4 mid fishes produce 1 oil
and 10 large fishes produce 1 oil together
I think this isn’t meant to be intended and should be opposite.
No, this is working as intended. The small fish are, I believe “unappetizing fish”, which means they are small greasy fish. Think anchovies or sardines. The larger fish are “exotic fish” and are more meat than oil.
Ah ok ‘unappetizing’ make sense
