I have a problem with Turtles coming back in force !!!Last year a guy set traps & caught quiet a few,that thinned them out pretty good,but now their back.I'm trying to get the guy back but can't find him. Has anyone had any similar problems or solutions ? I don't think turtles benefit ponds in any way .. do they ? I have three small ponds..under a acre ,but 17'-20'deep & only 4 years old.
