Teacher's comment reads:
Okay, okay, I concede, animals that would naturally eat fish in the wild would eat it raw, but at the time I was thinking of seagulls that are perfectly happy to steal cooked fish from any hapless person in their vicinity. Also bears, in, say, America, that raid campsites, would not be very likely to turn their noses up at cooked fish simply because it was cooked. Teacher was being mindlessly rigid, imo.
