The climate change hypothesis presumes re-animating poison that was dumped some time in the past. And that perhaps the sediment is being disturbed.

In the past, the Soviet Union controlled this area, and they are well known for the massive ecological disasters they created.

It wouldn't surprise me at all if this turned out to be the case here.

Back during the USSR it was Poland and the DDR, but yeah they didn't care atvall about the environment. Not that the west did, the Rhein was basically a dead river at one point in time due to polution.

Most fishes shown in the photos are carps. I assume that are mud carps (bottom feeders), but identifying correctly the species could help to understand the path followed by the poison, and their origin.

If is climate change, why aren't we seeing thousands of similar cases in other European rivers? Should be happening in half or Russia currently

They found a lot of salts that shouldn't be there.

Cyanotoxin hypothesis

Daily cycles on this graph [1] and oxygen surplus can be explained by hyperactivity of organisms that do photosynthesis - cyanobacteries and algae. Something boosted their activity. It might be natural, caused by high temperature very low level of water. Might be because someone contaminated the river with something that worked as fertilizer.

Dogs don't eat algae, and there are killed beavers also.

Either you have mercury or you haven't. Blue algae are ephemeral and don't store mercury, If I'm not wrong (I could be wrong)

Wildfires can release mercury, stirring the bottom could (in theory) release mercury and environmental terrorists (from Poland, Germany or other countries) can trow poison in the water, of course. We can see a sudden global pattern of environmental crimes all around Europe since the last months (and don't tell me that is climate change, most wildfires were deliberate and systematic).

A start would be identifying the organisms killed, the level of poisons found in the last years and the type of poison(s) found in their corpses.

We know that at least seven species of fishes were affected. Maybe covering the main trophic chains

You seem to be missing one potential candidate state already responsible for some huge environmental disasters this year.

The Police is offering a reward of 200000 Euro for information that could lead to the arrest of the terrorists
