That wasn't the case. When you get an HQ fish there's a very distinct animation, so I could tell it was for sure an NQ fish. Apparently the size, and therefore the purity, of an NQ fish is completely random. So unless I'm missing something, fishing is a very unreliable way to collect clusters if you look at how easily you can get tons of fire clusters, for example, while mining. It's sad.
