Glad to hear your semester at school has gone so well. Congrats on the great grades... The dead fish look like very large gizzard shad to me, but I could be wrong. With the face chewed off and decomposing, it's hard to tell but that is my best guess. I can say, it definitely isn't a grass carp though... Grass carp are more elongated and have different fin shapes. Very pretty heron pic! Your place has quite the biodiversity...
