It shouldn't be that hard to rule out/confirm GBD, a large percentage will have "popeye"

GBD is mainly only a concern for live fish haulers. It's the risk of OD'ing your fish on oxygen, which is really pretty easy to do. Or if the fish had eaten before loadout the excreted nitrogen can do the same. Any gas in supersaturation can cause it. Tailwaters can concentrate supersaturated conditions, so if the carp were determined enough to stay there, I guess it could croak 'em.

Locks and dams are typically hard on blood and bladder gasses in fish, and spring mortality is pretty common too.

The sad part is, all those dead fish are probably just a drop in the bucket compared to what's still in the river.

It would be nice to see the commercial harvest interests gain some traction on this species.

Soylent Gray anyone?

Yes, that would be the best ticket. I mean geez, over harvest/ poaching can destroy virtually every other type of gamefish.

Too bad they don't have a type of "Weed and Feed" for fish species!! Or somehow mutate them into a sterile hybrid.
