The common carp (Cyprinus carpio)

[Jace]

We get carp throughout all our locals lakes, streams and rivers, as well as the crud-covered canals with putrid green water. I also assume the carp sold in the local markets are also from the same sources (especially the shitty canals in the cities, which always seem to have guys lounging about nearby with rods and nets), which is why we don't buy them.
I've also seen some massive goldfish (close to a meter long and probably weighing quite a few kilos) in ornamental ponds, which I figure will disappear as soon as the balloon goes up and people realize TPTB won't be after them.
