RE: Whats the point??
they make excellent fertilizer... and actually when taken from clean water they are good eating if properly prepared... the thing to do is skin and filet them... then take all the red meat off the outside of the filet... from there they are good baked, poached, broiled, fried, boiled, in kabobs, stew, sauteed, no wait a minute that was in Forrest Gump about the shrimp... lol, once you get them cleaned up you can do them up about any way you'd like to do fish...
other than that what we're doing is ridding the water of an invasive species that has no redeeming factors about it... they are a scourge that needs kept under control by any means...
