it would be simpler to just take your wire mesh and make a round trap. Make it however wide you want. I make em about 8 inches wide. Then just make two funnels out of the same wire and tie them into the ends. Of course you have to cut a hole in the little end of the funnel. Make it just big enough for the biggest bream you would want to catch. Throw in some dry dog food and pitch it in a pond. Oh yeah, cut a square hole in the middle big enough to get your hand in and cover it with a nother piece of mesh. Just wire it on two sides and then when you need to open it, take one wire off and wah-lah!
