General & History
The category "Lobster" includes several crustacean families that are not
necessarily closely related. True lobsters have large claws. Crayfish are
closely related to true lobsters. Spiny lobsters, which have no claws but very
strong jaws, are related only as members of the order Decapoda,
which makes them as closely related as crabs. Spiny lobsters are warm water
creatures while true lobsters reach their maximum development in the cold
waters of the North Atlantic off the coast of New England (U.S.) and
Canada.
Buying, Cleaning & Cooking
Killing Lobsters
If you've bought your lobster live you have to kill it before you can
eat it. Dying is never a pleasant experience, not for us or for lobsters,
so you want to kill it as cleanly and quickly as possible. The question of
whether "lobsters don't feel pain like we do" is still unresolved with
conflicting experimental data, but we should presume they do. There are
several methods used.
- The traditional method is by dumping the lobster face first into a big
pot of boiling water. Some consider this cruel and say the lobsters scream.
Looking at it logically, the lobster's brain is right behind the eyes, so
there may or may not be a moment of pain, but the brain should be cooked in
less than a second and the pain forgotten. The "scream" is actually air
exiting from under the shell due to the temperature change. The body may
still twitch but there's no lobster in there anymore.
- Set a knife lengthwise over the front of the head and hit it down with
a soft faced mallet splitting the front of the head and the brain. This should
produce an almost instant loss of consciousness but the body may still react
for a minute or more.
- Some feel the lobster should be sedated by stashing in the freezer for
twenty minutes to an hour or more before dropping in the boiling water. This
may or may not be effective.
- Others feel the lobster should be sedated by soaking in a salt solution
before dropping in the boiling water. Having observed crabs react to water
of the wrong salinity I'm not going to recommend this without more evidence,
it may be very painful to the lobster.
Varieties
American Lobster -
[Maine Lobster, Northern Lobster, Homarus americanus]
These true lobsters are found as far south as North Carolina but achieve
their maximum numbers and development from Maine (U.S>) to Labrador, Canada.
They can grow as large as 44 pounds and over 3 feet long but the average
market size is between 1.5 and 2 pounds. Lobsters are brown to greenish but
about 1 in a million is bright blue and about one in 30 million is yellow.
A very few are albinos, which don't turn red when cooked as the others do.

Spiny Lobsters - [langouste,
Rock Lobster, family Palinuridae, genus Palinurus (Mediterranean),
Panulirus (Americas, Australia & China)]
Unlike true lobsters, spiny lobsters have no claws but very strong jaws
and a lot of protective spines. Found worldwide in both hemispheres they
prefer warmer waters and are generally nocturnal. The Australians, who
as usual get everything upside down and backwards, call them Crayfish.
Spiny lobsters have been around since the Cretaceous, about 110 million
years ago.

Western Spiny Lobster -
[Crayfish (Australia), Panulirus cygnus]
Native to the West Coast of Australia, this lobster accounts for the
most valuable fishery in Australia with somewhere around 10,000 tons landed
per year. The fishery is certified as sustainable.

California Spiny Lobster -
[Bugs (California), Panulirus interruptus]
Found from Monterey Bay, California to the tip of Baja California this
lobster has no claws but jaws strong enough to crush clams. They can grow
to 3 feet long and the official weight record is 16 pounds but specimens
to 26 pounds have been reported unofficially. The fishery is quite efficient
so few make it beyond 2 pounds today, but it is also a highly regulated
fishery and considered sustainable.Prep &

Caribbean Spiny Lobster -
[Florida Spiny Lobster, Panulirus argus]
This lobster is found in the tropical and subtropical Atlantic,
Caribbean and Gulf of Mexico. They can grow up to 16 pounds. Most are
caught in the Florida keys, but other areas of the Caribbean also harvest
them, particularly the Bahamas.

Crayfish
|
Crayfish are freshwater lobsters, generally much smaller than ocean lobsters.
The photo specimens (pre-cooked and frozen) were farm raised in China, the
larger being 3-1/2 inches long from nose tip to tail tip and weighing 0.7
ounces. The whole tray of 19 of them weighed 11.1 ounces for 0.58 ounces each
and the whole 19 yielded 1.7 ounces of tail meat (15%). Nothing else edible
was found on these critters. Considering the tray cost US $2.25, that's $21
