I can't help with Miner or Botonist, but my Fisher's colectibility is 1pt/tenth of an ilm. So aa say, 49.5 Ilm fiah is worth 495 Colectibility Points.

But with Fisher being entierly RNG based, it's almost certain that Mjner and Botonist work diffrent. Bug my Gathering Rate seemed to effect numbers more than perception.
