Can't give you a accurate % of any 1 species Rock, but I drove Rt 46 a couple weekends ago & the ditches were filled with dead fish, most looked like tilapia, however, only seen from road passing through & with the water flow from that area, the fish would have come from the puzzle lake area=a low O2 levels in shallow waters & stirred up muck from the bottom during the hurricane. On a positive outlook forward for the ones that survived, there will be less competition for feed & may produce some good size SLABS.....
