Sometimes? I can remember when the gypsy moths first got to Pennsylvania. There was a lot of talk about if the forests were going to survive it. It was the height of summer and there were NO LEAVES on the trees, in huge areas that just spread as the caterpillars moved outward.
Article on lake drawdown / rotenone treatment to get rid of carp:

Lots of people have thought of this, and it does not work that well from a commercial standpoint. Too fuel consumptive, for one thing, and you don’t catch as many fish as you do by traditional means, meaning gill or trammel nets. If you are only fishing for the large ones, you can use gill or trammel nets without catching too many natives, because you just use mesh that is too big for most of them, and you use short sets and drive the fish.
Plus, only silver carp jump. The very similar bighead carp does not, and both are problems.

I just got another envelope of clippings from my mother in Florida. One was about piranha being found in a local lake. A man caught a foot-long red belly piranha and called the Fish and Wildlife Commission about it. As piranha are non-native and can destroy the local habitat, officials decided to poison the whole lake with rotenone. IMO the officials had a very convincing argument. Florida already has problems with Quaker parrots, many species of iguana, pythons, anacondas and Nile monitor lizards. However, the fisherman in the story was worried that even after planned restocking, his fishing whole would never be the same. ‘If I had known this would happen, I never would have called FWC.’ he said. He was also upset they would not let him keep the piranha for mounting.
They’re not dead yet…
They’re just resting. (Or is this what you just said?)
:smack:Just got it.
No worries.
So mine was from a different source. :dubious:
Gotta be more confident, Leo.
They’re doing something interesting in a local lake. There is a tiny snail (New Zealand mud snail) that has invaded Capital lake. The lake is near the sound, so they drained the lake then filled it with sea water. They will completely drain it and replace the fresh water after they have made sure all the little destructive critters are dead, about a week.
Nah, I’m callin’ ya Bruce.
I’m into political science, myself.
Didn’t Keith Richards do something like this a number of times?
heh. Unless you are me. When I was in college I was a wildlife major taking a wetlands class. We went out to do electroshocking for a fish survey. You shock the fisj, they float up stunned and you scoop them up in a net to measure and tag them, then release them back into the pond.
Netting the stunned fish takes a bit of skill - they recover fairly rapidly. I missed them, so I repeated the shock.
And missed them all again. So I shocked them again. And once more.
Fish recover well from being shocked once. Maybe twice. After being shocked 4 times, they were very easy to catch, since they were dead.
I got an F for that assignment.
Toward the end, were they just floating there, gurgling, “Don’t tase me, Moz!”?
Sucks about the fish and your grade.
So… How many fish did you end up killing?
Don’t remember exactly, but more than 10.
The other fun thing about that class was one guy had a hole in his hip waders - he kept getting shocked.
Guess electroshocking isn’t the thing for me. I have to sets of waders and they both have holes in them. Fine around here but I’ll have to get a new pair before I head out to the Sierras.
