My mom works for the Forest Service and worked on a fish kill of a fishing reservoir. They estimated that up to 93% of the fish in one of their reservoir was trash fish and carp. Mostly from people using live bait, which is illegal. They used Rotenone because it degrades quickly in nature and is naturally occurring. I heard rumors at the time that the Dept of the Interior used their entire Rotenone supply to kill the lake :eek:
the USFS and power companies that generate power with hydroelectric usually count fish via streams and rivers, that way they’re all concentrated in one spot vs going out into the vast body of water.
Pretty normal, since many management agencies don’t keep the stuff on hand. Those that follow that strategy just buy what the need when they need it. Despite the fact that rotenone is pretty inoccuous as a pesticide goes, it still is a HAZMAT. Storing it requires following some rules, having a relatively safe place, etc. Easier to just buy what you need when you need it.
I was just listening to a guy talk about electroshocking. Evidently they recently got some nice new hip waders that were fancy breathable (Gore-tex-like) material, which avoids the whole “condensed perspiration making the inside of the waders wet and clammy” problem you get with old-fashioned rubberized waders. Sadly, it turned out that, unlike rubber, gore-tex can conduct electricity through it.
