Does rng scale with gathering on Fsh?

Perception has nothing to do with catching rate or size.

While perception has nothing to do with catching rate, it definitely has something to do with size. HQ fish are larger than NQ fish, which is why "HQing" is favorable for collectables, as the size of the fish translates to the collectability.

At least for hq rate, i believe it should be ~15% up to a max of 20% (food included) +50% if patience I = 65-70% hq rate which could be possible.

Base HQ chance (with enough perception, excluding the increase from Patience I/II) likely doesn't go past 15%, similar to Miner/Botanist.
