Usually when you see Maine Lobster (Homarus americanus) for sale frozen, it's because it has died.
In Maine when I Was growing up and indeed in all of New England, no one sold frozen Maine Lobster as the innards start to decompose very quickly after one dies.
From time to time over the decades I have seen various commercial attempts to market frozen Maine Lobster of which I am sure none have been successful.
The frozen Lobster tails you usually see for sale are almost always Spiny Lobster, a species without claws.
Quality varies from good to awful. Decades ago you could find some good ones in the Midwest, not anymore.
To enjoy a quality Lobster, take the time to go to H-Mart, purchase live out of the large tanks they have, bring home and cook that day. Price right now has been holding steady at $8.99/#, size is about 1#.
Once in a while they get a shipment of1.5 to 3.5# Lobsters and that is the time to splurge.
So the question is what is Jerry selling frozen, Maine or Spiny lobster tail?
I have also seen small spiny lobster tails from who knows where an of what quality sold over the decades. None of which we purchase.-Dick
