While you're deciding what to do, you should get yourself or a friend to start some hard fishing for the LMB now. Whatever number of sexually mature LMB you can remove now will only help down the line.
Use shiners or fatheads for bait. Spray crawfish scent/attractant directly on the shiner or fathead (don't worry, the minnows love it).
As I mentioned before, if you don't get them before they spawn, you'll probably have several thousand LMB, especially with no density of predator fish.
