Eliminating too much prey species effects fish growth, very short term lots of free food in dead and dieing shad...long term less food means less growth thinner fish, smaller recruits for future catches....the hyper cold event like this has not happened since the mid to late 70s, even then might not have been as severe....the smaller benthic critters, plankton etc are unknowns hoping they get through this.....prob see fewer if any armadillos for a few decades, I’m sure it’s killed back fire ants ( no loss) the old line was about Jackson Mississippi south, now it may have wiped out most in western gulf coast states...many plants will freeze out, non native on the edges....coastal fisheries have experienced huge fish kills...ironically pest species like hard head cats, puffers.....sea turtles hit hard....makes you wonder what kind of critters nature will give us in the next ice age
