CALLINECTES SAPIDUS BLUE CRAB
Now we come to the most important crab of all, Callinectes sapidus, the common blue crab. A whole fishing industry, community and special breed of crab fisherman have developed around this creature that is caught by the hundreds of thousands of pounds and ends up in cooking pots, boiled to a bright orange. It has a delicious flavor and is prized by anyone who appreciates seafood. Although Callinectes sapidus was a western Atlantic species, it has spread throughout the world in the last 20 years. It now occurs in the Red Sea on the Pacific coast and even in the Indian Ocean, and many other countries are harvesting it. But nowhere is the crab more appreciated than in Maryland, where they
are caught by the tons, dumped into boiling vats and flavored and then
delivered to restaurants and bars where they are consumed with beer.
When the blue crab catch declined in Maryland and Virginia a Congressional
hearing was called to determine why they disappeared. Biologists in the
area have put considerable time and effort into learning something
about their habits.
But the blue crab in Panacea, Florida, has its own history, and that is
worth relating. Years ago crabs were fished in Panacea with a long
line, a coarse hair rope that was baited with salted bull-noses. It was a
stinking, unpleasant mess, but the fishermen put out the thousands of
yards of hair rope and bait along the marshes and up the Ochlockonee
River working from skiffs. Flies buzzed noisily overhead, and when a summer
breeze came along, the fishermen were pleased to get relief from the
odorous bait.
The mile-long lines were set and buoyed with an inner tube, one at
each end. The salted bull-nose was cut into long thin strips and looped
every two feet over the coarse hair rope, and it worked very well. Great
big sleek male blue crabs came out of the marshes and up from the muddy
bottom, perched on the line and shredded the tough bait with their
large claws. The "jimmies," as the big males were called, were prized
because of their large size; often they were more than seven inches across
the carapace. The fishermen usually worked lines at night with lighted
gasoline lanterns. They eased along with their boats, lifting the line
and shaking the crabs into weather-beaten fish boxes. The catches at
night were better than in the day because the crabs were stunned by the
blazing light while they were devouring the bait, and clung to the
lines. Nonetheless, all that lifting and shaking was hard work. The catches
were lucrative, and a crew of men was able to bring in as many as
40,000 pounds of crabs in a single night.
At the end of the fishing trip when they finished running the lines,
they had to coil the rope into a big tin washbasin and sprinkle salt on
it to keep the bait from rotting. By the time they reached the dock,
unloaded and often helped boil the crabs at the crab house, they were
exhausted.
One day a man came down from Virginia and started crabbing. He didn't
use a set line, but brought rolls of chicken wire, and began shaping
them into wire crab traps, which the residents had never seen. He told
them there was no need to fish all night; they could stay home and "make
love to the baby's mama." The people of Panacea were skeptical, but he
started off into the sunrise one morning with his traps and a box of
threadfin herring. The traps worked, they caught crabs while he stayed on
the shore: they did all the work for him.
The fishermen immediately began buying rolls of chicken wire and
building traps. The population of Panacea soared as it never had before
because the men now stayed home at night. Fishermen were bringing in crabs
by the ton - the crab traps enabled them to fish in foul weather; they
were making more money with less effort, so to make even more money
they built bigger boats and bought more powerful outboard motors. Of
course their expenses soared and they had to work all the harder to pay for
expensive gear.
Suddenly crab houses like weeds began to spring up all over Panacea. A
crab house opened in Apalachicola and East Point, and down in Perry,
Florida. Everybody started crabbing, even college students had traps set
and made extra money. As the industry prospered, the crab houses
installed giant steel steamers, erected bigger buildings with more tables
where more women could pick more crab meat. One man, with technology from
the industry in Maryland, put in a gigantic freezer plant so meat could
be stockpiled.
In the middle 1950s and mid-1960s the crabbing industry boomed. The crabs seemed to be unlimited out in the bay, and it was nothing for a man to come back with 3000 or 4000 pounds of crab in a single day's catch. One man and his two sons broke the record and brought in 6500 pounds of crab, working 350 traps in a single afternoon.
Trap after trap would be snatched up, emptied of its contents and
rebaited. Fisherman worked night and day striking schools of menhaden and
selling them to the crab houses which sold them back to the crabbers at
double price for bait. The men worked seven days a week, twelve hours a
day and got while the getting was good. The wire traps were set in
shallow estuaries around the marshes to catch the male crabs, as well as
offshore where the females congregated. The traps have a bait cage with
two or more funnels that lead into it. The crab, smelling the decaying
fish within, crawls about the sides of the wire-meshed trap until it
finds the opening to the funnel and crawls in. As many as forty pounds of
blue crabs can end up in a single trap, although the average catch is
much less.
The crabbers worked year round, in calm seas and stormy surfs; the
ambitious one pulled their traps in freezing pouring rain, wearing
yellow-and-black slicker suits. It didn't matter whether they caught males or
females, small or big there were no closed seasons, no size limit and no
conservation laws. Gravid females carrying sponge-egg masses were
pulled out by tens of thousands of pounds. The crab houses cut the price on
gravid females by two cents on the pound because the sponge, which was
thrown out at the fish house, jacked up the weight, but the crabbers
went right on pulling their traps. Periodically the fish houses
drastically cut the price of the crabs. The fishermen griped but kept working.
The fish houses bought new equipment, the owners built bigger and better
houses, bought tractor-trailer trucks to haul crabmeat and fish up
north, and still the price kept falling. The landing where the crabbers went out in their skiffs looked like a crowded parking lot. The water was jammed with boats, littered with rotting bait, conchs and spider crabs discarded from the traps, and the oyster-shell ramp above the boat landing was covered with rusted-out pick-up trucks and old cars that busily roared up and down the rutted sand roads with noisy mufflers at all hours of the morning.
When the prices were high the crews would return to the dock exhausted
but happy. They helped each other unload their weighted skiffs, piling
the crabs into the old trucks, which sagged on their axles. They backed
their trucks up to the loading ramps of the crab houses. Stone crabs
were culled out, their claws broken off, and they were cooked and sold as
epicurean delights.
Into the small hours of the morning the great cookers steamed and
hissed as tons upon tons of blue crabs were killed and cooked, and dumped
out on tables. Even with steadily declining prices the fishermen's
economy boomed, their wives and children picked the meats, and refrigerated
trucks roared out of Panacea, hauling the meat to New York, Maryland
and Philadelphia markets.
When the price dropped below four cents a pound, the fishermen
grumbled and told the fish-house owners they couldn't make a living. They had
to catch an even greater quantity of crabs to pay their bills. After a
few years the traps produced less and less from overfishing, and the
checks at the end of the week were leaner and leaner. Where the
rock-landing boat dock was once jammed with boats and cars, only a few remained, because the crabbers started going to Pensacola and even to Louisiana and Virginia, where the crabbing was better and the prices were high. But nonetheless, the existing crab stocks seemed to drop to nothing in a very few short years. The packing houses laid off the women; only the fastest pickers stayed on. Eventually the industry disappeared almost entirely, and for many years it was difficult to find any quantity of crabs at all in the bays.
It is not a bad thing to exploit a stock of marine organisms if proper
conservation measures are practiced. A female blue crab produces
100,000 eggs-and under good conditions, lots of marshes, proper salinity,
temperature and pH conditions, low pesticide levels, the crabs will
multiply and thrive. But Wakulla and Franklin counties in north Florida have
always resisted conservation efforts.
Attempts to place closed seasons in Florida and prohibit the taking of
sponge females were stopped cold by vote-hungry politicians. In these
two beautiful but backward areas, there are few nursery ground areas I
closed to shrimping and no size limits are placed on speckled trout!
The state of Florida set up a state aquatic preserve system that I
would prohibit the use of state-owned submerged lands for land-fill I and
development, and prohibit shell mining and oil rigs. More than 20 :
aquatic preserves around the state had been proposed and accepted by
the communities, but the Ochlockonee River Aquatic Preserve was killed
by opposition from the county commissioners, politicians, and
developers and fishermen who feared it would -close these areas to fishing
sometime in the distant future. At a local public hearing the
conservationists were outnumbered three to one.
I cannot help but be depressed by the area's future. Panacea is not a
Hudson River community where people have seen progress, factories and
buildings until they want to vomit, and are now gallantly fighting to
save what precious little bit of life is left in the overburdened waters.
In Panacea the conservationists are a pitiful minority, voices crying
in the wilderness.
I stand on my dock looking out at the green marshes of Fiddler's Point
across the bay, one of the areas that so many want to turn into a
gleaming white sandy beach, motels, neon lights and highrise apartments.
The marshes are worth fighting to save, and so are the crabs. There are
still a few crabs that crawl up on the pilings of my dock, and children
come down to fish for them with a string and a fish head, just as I did
years ago when I first moved to Florida. There is a difference though,
it takes them all day to get a Styrofoam picnic chest full. Little more
than a decade ago, when I was just a boy with time on my hands, it took
only an exciting hour to snatch up a heaping bushel of blue crabs.
Fishing for blue crabs is a poor man's sport because it takes only a little
bait and string. The crab chews on the bait, gets all engrossed in its
meal, and is too greedy to let go or is too engrossed in its meal to
feel itself being lifted from the water and then rudely dumped into a
bucket. And then it's dumped into scalding hot water. The blue crab with
its frantic greed and big appetite readily enters traps, as the people
who once caught them for a living soon will enter their own particular
traps in their pursuit of the developer's fast buck.
There is only one hope for the estuaries in north Florida, and that is
a federal coastal zoning law that will protect productive marshes from
future development. There is talk of such a bill in Washington, but if
something is not done soon it will be too late for north Florida.
If the environment is not substantially altered and conservation
measures are placed on gravid females, the bumper crops of blue crabs may
come back again the way I remember them almost 15 years ago when I first
moved to Florida.
There are still a few crabbers who go out every morning and make a
modest living at it. Even though the community has changed there are still
a few houses that have crab traps piled up in their front yard.
Fishermen keep tunnelboats and crabbing skiffs at the city dock. There should
be crab fisherman because the blue crab is delicious and wonderful to
eat and there should be plenty of them for everyone.
Blue crabs (Callinectes sapidus) make wonderful research material
because they are alert and responsive animals. Scientists study their eyes,
their nervous systems and their reproduction, and in past years we have
shipped them out by the hundreds. They make excellent scavengers for
large aquariums and will eat anything that lies dead on the bottom.
It is perhaps the most vicious and alert crab to be found anywhere, no
sooner does your hand approach one than it stretches its long, pinching
claws up at you, pincers extended and ready to latch onto your fingers.
Crabbers use a special set of crab tongs that is most efficient at
picking them up; only they latch on the tongs and the pincers must be
undone or the chelae will break. When they are particularly disturbed or the
chelae is damaged, the crab autotomizes and the leg stiffens and breaks
off. They will regenerate a new one after a time.
They use their chelae for shredding their food, which they ravenously
stuff into their mouths and in almost no time a blue crab can tear a
fish to pieces, enthusiastically gobbling it down. If there
is no fish to eat, they eat each other, and in a collection of crabs it
is a constant struggle for survival of the fittest. If one is damaged,
immediately they all converge upon it and rip it apart.
They have the right to be so defensive because I know of few marine
animals with the exception of shrimp and lobsters that are so eagerly
sought for food. Aside from man doing his usual job of gathering something
tasty by the ton, sharks, sea turtles and any large fish eat adult blue
crabs. The young are hungrily swallowed by smaller fish, rays and
birds.
The young tend to live in shallow water, amidst the seagrass meadows,
up creek beds and at the head of the bay where they can burrow into
shallow mud. They are in the process of molting generally, particularly
during the summer months, and are eagerly sought after by another grade of
commercial fishermen. The soft-shell-crab fishing industry gathers the
peelers by the thousands, keeps them in vats of running or
recirculating sea water, and just as they molt out of their shell, they are removed and frozen. The soft-shell crab can be fried in its entirety, shell and all, and makes a tasty meal.
One of the primary difficulties in raising soft-shell blue crabs is
keeping the hard crabs from tearing the soft crabs to pieces and devouring
them. A man in the crab business must be constantly on the watch,
removing the soft crabs as quickly as they molt.
When a number of crabs are taken by traps or by net and tossed into a
bucket, you can expect the biggest mess of tangled, pinching crabs
imaginable. Each crab has latched onto the leg or body of the adjoining
crab, and if you lift one crab out there may be a chain of a dozen other
individuals attached.
When collecting crabs for specimens where all limbs must be intact, it
is necessary to keep them isolated from each other. They readily tear
off appendages and pinch themselves to pieces. This is particularly true
during transport when crabs are being shipped across country. A good
technique, we found, is to wrap them individually in wet paper towels,
covering up their eyes. Blocking their sight is most important, for once
they are blind they lie still. If they are in a shallow tank and you
walk anywhere near, immediately they raise their claws defensively and
snap at you. And should you venture too close to the tank and forget
about them, you might receive a savage pinch.
MENIPPE MERCENARIA STONE CRAB
The stone crab (Menippe mercenaria) reminds me of the great Old Man of
the Mountain. There the crab sits in his burrow with his great massive
claws folded up in front of him daring anyone to come close. The stone
crab in the south is prized as a great delicacy. Fishermen collect them,
break the claws off and throw the crab back. If they survive that long
in a defenseless condition, they will regenerate new massive claws over
a period of a year. Farming stone crabs has been the interest of
numerous entrepreneurs because the claws fetch close to two dollars a pound,
but the rate of growth in the crab, according to investigations at the
University of Miami, has proved too slow and cumbersome for commercial
use.
So they are captured in crab traps along with blue crabs. In certain
localities a wooden slat trap that resembles a lobster pot is used. In
either case, if the trap is set on a bottom of flat lime rock or oyster
reef, chances are it will get quite a few stone crabs. They dwell in
crevices and small caves with only their massive brown claws tipped with
black sticking out.
When you approach one it quickly draws back into its burrow. A good
collector, wearing canvas gloves, can reach into the burrow and snatch
the stone crab out. But you've got to watch those claws. Some of them are
a full eight inches in length and so strong that the crab uses them to
crush oysters, grinding the shell to bits with one claw, scooping out the meat and putting it into its mouth with the other. Actually, no one has lost a finger from a stone crab to my knowledge. I know several crabbers who have received some vicious pinches from them, severe black-and-blue marks, but have not lost a finger. At one point I was digging around in our gravel-filled tanks for some specimen or other, and my finger found its way into the clutches of a monster stone crab and nearly got mangled.
A word at this point-when any big crab latches onto your finger, the
worst thing you can do is snap the claw off. Even though you're in pain,
the pain will be worse if you do so, because the claw gives a spasmodic
tightening when suddenly broken off. The best thing to do is place
crab, hand (or toe) and all, into a bucket of water and let it relax and it
lets go of its own accord. Or you can take careful aim with a hammer
and crush the claw at the base of the first joint where the muscle
attaches. But if you miss you may be worse off than before. I remember one
captain on a shrimp boat who had a big Portunus grab onto his toe.
Shouting, he ordered the crew to bring him a bucket of water, and gently
edged the crab into the bucket. Presently the crab tired of holding on and
let go. The captain, in a rage, kicked the bucket over and stamped the
crab to pieces.
Blue crabs, other portunid crabs and sluggish bottom-dwelling crabs can
be the predominant part of a shrimp-boat catch. Therefore, it is very
important that a fisherman protect his hands and other parts while
culling through the catch. In the Gulf, I knew one deckhand who encountered
a great deal of distress, all of it his own doing.
He had leaky pants, and parts of him were hanging out. And as he
squatted over the catch taking out handfuls of shrimp, a blue crab reached
up and grabbed a claw-full and hung on. The shrimper jumped and leaped
and howled and hopped up and down the deck, supporting the crab with his
hand but not daring to pull it off. Presently the rest of the crew,
holding their sides with laughter, fetched him a bucket of water and the
crab and the attached parts were placed in it. After what was described
as a very long time the crab let go.
