In reference to CentOre’s recent article, “Subsistence Fishing After TEOTWAWKI”, one method not mentioned which works very well (speaking from experience) is to kill a non-edible animal like a prairie dog and hang it over a bank.
After a couple of days maggots begin to fall off of the decaying carcass and the fish learn to come to that bank to get a free meal.
Then using yo-yo fishing lines you bait whatever hooks you use with scraps and pretty much I’ve never gone without a pan full of fish a day to eat.
The other method is to use 12 volt DC current. This is the same trick that the fish and wildlife guys use to do fish counts. Place a couple of copper rods several feet apart in the water — driven into the ground. Hook up your jumper cables from your vehicle and let it run for a bit. The 12 volt DC current acts as a fish magnet and you can pick and choose which ones you want to eat. – Hugh D.
