There's no proof that the fish have recently evolved bonjina.
There is. The proof is that the fish didn't previously exist. They do now. The only possible explanation for that is that they have recently evolved. No other possible explanation could explain it. The old "they might have existed but not been discovered" story is a load of old balloney because humans have explored every corner of the earth.

How does one know when one has discovered a new species... being as not a single person knows all species of everything in the world?
Not
one single person knows, no. That doesn't mean anything - not one single person knows how every single part on a boeing 747 works, they still manage to get built and take off though. If you think you've discovered a new species sharky then go and approach a science magazine, they'll soon tell you whether you're barking up the wrong tree.

Presumably said person would have to research quite thoroughly whether the animal they had spotted was already documented... bit tricky I would imagine for afore mentioned Eskimo.
You'd have to take claimed retrospective discoveries by eskimos with a pinch of salt at the end of the day, because they're likely to SAY they discovered them ages ago to try and get famous.

As an aside, it may be an animal they (Eskimos) are used to seeing, in which case they may assume that everyone knows about them...
In which case they probably do. You don't really get 'wild' eskimos much nowadays, that don't know any part of the earth other than a snow hut - they're just normal people that live in a certain part of norway and greenland who like the snow and therefore go and live in igloos for certain months of the year - because they like the novelty, the climate, fish, tranquility, snowboarding - whatever.

Hey Bonj, a new bird has just evolved in Nepal, and others are waiting to evolve according to
this report
I'd be surprised if the fish in my avatar was the only newly evolved species of recent times, to be honest..
