Even a barb wire fence hasn't kept me out of places. Either under or over. Woven wire fence with a strand of barb wire on top? Those are easy to get over too.
Reducing LMB via nests:
I just keep an eye on the pond and when I see LMB starting to make nests, I fish them out. Males will guard the nests, and a live nightcrawler fished on 8-10 pound test line, no weight works VERY well. Use a #4 hook, slip it thru the crawler under the collar, and cast past the nest. Bring the crawler back so it drops into the nest and let it squirm around. The LMB can't resist picking it up, and once they taste it they don't spit it back out. Set the hook and remove the LMB. That method isn't the best for C&R as they ususlly are hooked deep, but it's perfect for catch and keep. Polarized glasses are a must for fishing that way.
