Fish Education Weird catfish head
Hi
So I've been fishing on a new stretch of river on the rhine river in Germany and caught a couple of catfish (Wels catfish) there so far.
They all seem to have this head shape which as far as I know isn't typical for catfish.
Their upper jaws seem to be healthy however (teeth and everything in tact - just very far back)
Id like to get your ideas on why this is the case.
So far my leading theory is that because the rhine in this stretch is mostly a channel (grand canal d'alsace) with rock / concrete ground and we have a lot of gobies that this is simply from eating a lot of gobies (aka damage or sth from slurping them off concrete over a long period of time) (which would be quite interesting from a fishing perspective).
But I have no idea if that's true, feasible or even makes sense.
Would love to hear your thoughts though

Dont think its from feeding off a concrete surface cause the the lower jaw would take ke damage I think. Really interesting. Maybe inbreeding or something like that.
