any tips or what kind of equipment should be used ?
When I was a kid, my friend and I took a half-sheet of plywood, and just laid it in the water around the pebbles and rocks. We came back after a couple of weeks and lifted it up. . . .whoa baby! Craws everywhere. Of course, most of them would scatter, all we caught was what we could pick up with our bare hands. At the time, we were just looking for pets, not bait, still it worked like a charm.
Don't know if that helps
