Could this not have been simply an instinct to find cleaner waters? I'm surprised they didn't add another control group which injected something unpleasant that could be naturally found in an area, but would be undesirable - ammonia, some sort of acid, or something along those lines.

The title ie a bit misleading:

The study want to prove that cocaine is yet another polluter thar alters the fish behaviour even in the small quantities that can be found in the wild in polluted areas. Not that something is special or different about cocaine pollution.

So the control group in this case are fishes with an implant with no drug at all.

And just like that, smoked Salmon became popular again :)

BTW, did you knew municipalities can easily measure fluctuations in drug usage by testing the sewage water? In fact, sometimes they can see clear differences between different parts of the city.

We’re looking at you, Vancouver.

If that is not one good argument to start producing cocaine locally, then I don't know!

Save the fish.

What about the rats and turtles in sewers? They might become more agresive!

Roaming more widely may not be healthy for the salmon.

Whether it is or is not, is not a function of the cocaine though, but rather idiosyncrasies of the wider ecologies the salmon are in.

If roaming more widely introduces them to more productive food opportunities (or, lower predation) than their closer ecology, then it would be beneficial for them. If it does not, then it wouldn't be. Neither context is determined in the basic finding that cocaine causes them to roam more widely.

They’re in a better mood though.

I think another study is in order examining how cocaine affects breeding habits.
