Island economies are always complex since in many cases the island has to import so much stuff. But PR
has so many natural resources and grows so much of it's own food that the usual island economy arguments don't necessarily apply.
I don't know about the lobster pricing in PR
. I do know that if it was readily available fresh from the sea, I wouldn't buy frozen!
Many people are afraid to deal with live lobsters and prefer them to be already "processed" (dead).
