Fishy sounds

Hello everyone!

Ever since I started freediving, I've been surprised to know that many fish make sounds.
I haven't heard demersal species like snapper or grouper making sounds, but I've heard trevallies (Jacks) make an "ukk ukk" sound, and Spanish mackerel make a sort of nasal groaning sound. Another observation I've noted is that these fish tend to be louder when the water is murky. Is that their way of letting other fish know they're around in the murk? Pretty interesting stuff.

I know that the folks in california talk about the croaking sounds of WSB, and that got me interested in finding out which other fish make sounds and noises in the water.

Have you heard any fish making vocal sounds? Or can you associate certain sounds with certain fish?

I agree with all of you. Reefs sometimes sound like frying pans on full heat!
The strangest fish sound I've heard has to be spanish mackerel. It almost sounds like a goat when they're close by in bad viz.

What you call the Spanish mackerel is the Pacific narrow banded mackerel right? If so having never dove the other side of the world I can only imagine!

Yeah, it's called the narrow barred spanish mackerel. Possibly the most sought after fish in the UAE in terms of demand. In the murk, they look like missiles!
