I did find this link, but I don't think it will help out much, because there is nothing on the internet about it, other than this. http://en.allexperts.com/q/Wild-Animals-705/frozen-crab-life-thawed.htm. Or you can go to this link. Its about frozen lobsters coming back to life after thawed.
A lobster that you cook while it is alive will stay fresh longer than lobster you kill before putting it in the pot. There is no way to determine how long a frozen lobster will stay fresh after cooking, since you can't determine how long it was dead before someone froze it. well done lobster that was alive when it was cooked might stay fresh for up to five days. Medium-rare lobster will stay fresh for a maximum of three days. To ensure a lobster is safe to eat, make sure it reaches an internal temperature of 180 degrees F while it cooks.
