What Happened To The 800 Salmon?

Yesterday, citizen https://app.warera.io/user/6960c7b4e7c1e76708ece172 made a disturbing discovery.
800 salmon had somehow become 12.

After receiving an explanation, Kiwis announced that he would delete his account.
I have translated the exchange and attached the evidence below:

Since then, Kiwis has not logged in again.

Which raises several questions.

Where did the salmon go?

Was it Beitsas?

Was it Vatou?

Was it an unfortunate accident?

Or did the 788 missing salmon simply migrate to warmer waters?
Could https://app.warera.io/user/6813b759efecdf9bab1950cb comment where his fellow fish has migrated?

What we do know is that Kiwis' final words were:

"Thanks for the info. Good luck in the game."

And with that, he vanished.

Today marks Day 1 of our vigil.

Kiwis, if you are reading this...

Please come back.

Lithuania still has fish.
