Thanks, canyoncreek. 15 years ago I bought 1,000 Louisiana crawfish at the Vietnamese grocery store and released them into the pond. They and the bullfrogs are the only big animal species that survived when the pond dried up 5-6 years ago. When the water level came back up, the crawfish population exploded. My intention is to grow forage fish only and so I won't be using predator fish to control them. I'm confident that when the water temps come back up next year I'll be able to trap them out down to a healthy number for the pond.
Right now they've got me worried because they're no longer visibly feeding but are burrowing like crazy all around the shoreline but especially on the dam bank. I don't know how deep they burrow but I'm concerned that they may be compromising the structural integrity of the dam. Do you know if this is a valid concern?
