Interesting bit of trivia: the Great Lakes are connected to the Mississippi watershed by a canal, and there is a section of the canal that is electrified to discourage fish from crossing to the other side.
Not quite understanding why they turn the carp back rather than culling them. The video mentions something about heavy metals and PCBs, but I’m not seeing why that presents a problem as far as, I dunno, euthanizing and tossing them into a landfill? Or even just throwing the dead ones back into the lake? I can’t imagine a dead fish full of toxic substances is any worse than a live one that will, naturally, be dead sooner or later…
Yeah agreed. Just grind them. Somehow people have no problem depleting massive natural stocks of fish for food but when its a “pet” you can’t kill it? People are getting too soft…
Literally “design by committee”, probably.
The takeaway they don't say: When you tire of your goldfish, kill them instead of releasing them.
