pound for pound, Soft shells tend to have more meat than hard shells, as the shell weighs much less. Most large lobsters are mined off the coast of NJ in very deep water. they are then landed in the cape cod area of MA.

The water is very cold at those depths. Not many harvested Maine lobsters get to giant size. for some reason, the production of maine lobsters has skyrocketed, and the prices have fallen. I am not at all famaliar with nova scotia lobsters, but it is difficult to determine harvest location for most fish.

read recently where a guy illegally filled a boat with chilean sea bass and was chased half way around the world by authorities. he could have landed them in australia, or south africa.

The south african "rock lobster" is a giant crayfish, not a lobster.
