Apparently, the results were "encouraging."The equipment kept the beavers away, although they returned as soon as it was turned off.
It also worked on ducks and geese, although they had some problems with infrared waterfowl detection.
Using our simple extrapolation, instead of 20 megawatts, we might need a gigawatt.
The electric current, through a few different physical effects, draws the fish toward one of the electrodes and/or stuns them.
Simple extrapolation is misleading here, since we know that large animals respond to electricity differently. Well, according to an post by Jan Dean, a human who fell into the water in front of a typical electrofishing boat could easily die.
I assume they just mean records weren't kept before World War II, but it's technically possible that the war involved so many electrofishing deaths that they need to exclude it from the stats.
People who've reached 110 can pretty much do whatever the fuck they want, provided they aren't breaking any laws outside of drug ones. As in, determining if the older party is acting in a potentially predatory manor based on the naivety of the younger.
If someone 110 wants to continue doing coke every day, I'm not going to stop it. So the fact that the range gets pretty large starting somewhere around is based on people past their mid-30s having enough life under their belt to make good decisions for themselves.
