There are alot of crabs in the salty creek near me, and they fill up crab traps. One time I put some in a pan and they were cool to look at. Then I boiled some and felt bad. It made me decide that in the future I would knock them on the head first. I didn't know at the time that it was the humane was to deal with them before boiling.
But so far I haven'tdone more crab catching because I didn't want to bother the owners of the place I was at like I did last time, although he gasve me permission.
