Something fishy in Southie

Jason cannot figure out how a fish came by to be lying in the gutter along Columbia Road. Unless it's a sign of the End Times:

... It's not like the entire area was flooded by Dorchester Bay and this poor guy didn't make it back. I know we had a pretty major storm come through on Saturday night, with pounding rain and heavy winds. But could the storm have carried this fish-thing a good 200 yards from the water to where I found it?

It looks like one of those creatures in the fish tanks at Super 88, awaiting an untimely fate as part of some Asian cuisine. Perhaps someone bought this but dropped it before making it back to the kitchen? ...
