How to catch crawfish.
What doesn't work:
*Reaching into the water and trying to simply grab them
*Using gummy bears as bait
*Trying to whack them with a kayak paddle
*Pretending the kayak paddle is a rock, then lifting the unsuspecting crawfish out of the water once they're atop the paddle
*Aggressively attempting to trap them between a rock and a hard place, using the paddle to move them along
What does work:
*An actual trap with a chicken carcass as bait, left overnight.
Unfortunately, since we still had only eight the next morning (I blame the fact that we put the trap where the current was especially strong), that wasn't enough for a meal so we had to let them go. Next time, bring a net.
