There is a market for them in asia,they are supposed to be pretty good table fare if cleaned right. So why are we not marketing them over seas? We import asian shrimp,catfish, and frog legs, also a lot of tilapia is imported. So whats wrong? To begin with, smelly processing plants, what to do with the entrails and other stuff, folks seem to object to things like that, An example. years ago in Northern wisc. there was a nice clean walleye and smallmouth lake. Guys starting bringing in rusty crawfish as bait. It took 10 years for the crawdads to strip the whoile lake of vegatation, no weeds soon very few fish. A guy started to trap them, clean them and ship them down south where folks eat the heck out of em.Just when business was starting to get good, here comes the DOGOODERS. Too smelly, brings down property values, he was put out of business.The place was lake metonga in crandon wisc. So the state needed to spend tax payer money to try and solve the problem, their still at it. Like pogo said "we have met the enemy, its us"
