i went fishing on the salt and ohio river were the meet and i saw alot off big silver asian carp awiming upside down and then going back down are they dying for some reason. i saw one belly up for about 5 min close to shore and snaggedd it with my bass pole it didnt even put up a fight i used it for cut bait it was over 3ft. and i saw dead ones all over the shore appeard to be washed up and also saw alot of dead ones floating down the salt and acouple of buffalo. why were they swimmin upsidedwn and whats killing them dont getme wrong im glad there dying but could the pollution in the river be the culprit? and when i cut it up there ws a ton of whitemeat on them has anyone eatin one
