Some fish make loud splashing noises

Would like to add to this.

fish swimming noises don't seem to be respecting volume settings

1) fish swimming is always at 100% and almost seems (probably not actually) to get louder the longer you're around them

2) If you turn off friendly creatures sounds, there's still a weird "pip" glitch like sound that is at the same time as if they were making the swimming sounds

3) if you turn friendly creature sounds to 1%, it's still just as loud as 5-10-20-100%
Update
Seems to be fixed in 20w13a

No, I am experiencing this in 20w13b. I was confused and scared at first, but it went away after killing the salmon. Not every salmon made these noises.

this says resolved but it most certainly is not

Splashing issue still in 20w14a. After a while the splashing noise messes up other sounds, they won't play. For example no tree chopping sounds, etc.
