Augie, that design looks good. I modified a std funnel minnow trap and I figured out how to get the big boys. I cut into the opening of a 1/4" mesh minnow funnel and open it up to about 3". I filled an old sock with fish food and ty-wrapped to one half of trap. That sucker was FULL of big-dog craws this am. Only set 3 traps last night and caught only 7lbs total and only put 3 smaller craws back. I'm keeping after it until I don't see big craws or big numbers any more.
May try a piece of fish or chicken leftovers or something. Snakes have always worked great for us in traps but it's Russian roulette trying to actually find a rattler-which usually doesn't take much looking.. not many garters and I leave the bull snakes alone because they are too beneficial.
I don't know how long I can go with aeration off but I'm thinking I need to start that back up slowly at night soon.
