I was wondering what size do you guys think would be appropriate for a 10# catfish, diameter and length? Would a different size trap be needed to entice different size catfish?

Good ideas snrub. I was thinking of some stuff similar too. It may have been just before you joined PondBoss, but there was a guy selling some catfish traps. He got discouraged and left. He was even a brief advertiser here. His traps were expensive, and was probably the downfall, but he had a lot of work in them. It was on a trailer that backed into water. You fed them and got them used to eating. Then one day at feed time you closed the door and had bunches of fish. It was mobile so it could go from pond to pond easily.

Since catfish are cave dwellers, do you think having a box in the pond they would go into it as a residence? Perhaps let them get used to it, without feeding, and then close a door one day and trap them?

I hope Holt sees this and jumps in with his trap experience.
