White
shrimp, which account for more than two-thirds of Georgia's harvest,
spawn in the Atlantic Ocean from late March until September. At depths
of three to ten fathoms, females release 500,000 to 1 million eggs each
into the ocean. The eggs are fertilized as they pass the packet of
sperm, called the sand usually hatch in
twenty to twenty-four hours. The first larval stage, called a nauplius,
relies on its yolk sac for food and drifts as part of the microscopic
plants (phytoplankton) and animals (zooplankton). The later larval
stages begin to feed on phytoplankton, and after fifteen to twenty
days, the larval shrimp, which can drift 100 miles from their spawning
sites, enter the postlarval stage and are ready to migrate into the
sounds and brackish marshes. There, as juveniles, they feed on bottom
algae, small animals, and debris. Shrimp remain in the marshes and
sounds two to three months and mature before returning to the ocean. As
winter approaches, most white shrimp move out of sounds and travel
south. Those lucky enough to avoid the trawls, or nets used for fishing
at or near the bottom of the sea, return to become part of the next
year's spawning stock. Some white shrimp remain in the deep holes in
coastal streams, and they emerge in the spring and migrate offshore to
spawn.permatophore, that the male attaches to the female. Fertilized eggs then drift in ocean currents
Brown
shrimp have a similar life cycle but spawn in the late winter. The
postlarvae, ten to thirteen millimeters long, move into estuaries in
late March and April. By June the shrimp are adults and begin to move
offshore. They are an important harvest from June to August.
The Shrimping Industry
Shrimp are harvested by otter trawls, cast nets, and seines. More than 400 licensed shrimp boats do most of the commercial harvesting in Georgia.
The
fleet is made up of boats, or trawlers, twenty feet to one hundred feet
in length, with the bulk of the fleet between fifty-five feet and
seventy-five feet long. They shrimp from the coast all the way to eight
miles offshore. The boats pull as many as four otter trawls, which may
have head ropes (the lines at the top of the net's mouth) as long as
fifty-five feet. Wooden doors act as hydrofoils to open the nets under
water; the faster the trawls are pulled, the wider they open, but the
nets will come off the sea bottom if pulled too fast. The normal
trawling speed is two and a half knots, or just under three miles per
hour.
Catching
animals other than shrimp, called by-catch, is a particular concern. Up
to 2.7 pounds of by-catch are caught for every pound of shrimp
harvested off the Southeast coast. , which are protected by law, are
part of the by-catch. Sea turtles move into shallow nearshore areas,
and the female crawls onto the beach to lay her eggs during the summer,
at about the same time the shrimp season begins. Turtles swim in front
of the trawls until they are exhausted and then are swept into the net.
In the past they had no way to escape and drowned if the trawl was
pulled for longer than an hour and a half.
Turtle
excluder devices (TEDs) were developed by the U.S. National Marine
Fisheries Service, the University of Georgia Marine Extension Service,
and fishers. TEDs provide a hole in the trawl that allows turtles to
escape. Each TED has a grill or large mesh net panel that is sewn into
the net. This guides turtles and large fish out through the opening.
Shrimp are poor swimmers, so they are swept into the back of the net,
called the bag, along with the small fish.
Federal
and state agencies, concerned about fish populations, wanted to reduce
the fish by-catch by 50 percent, but TEDs reduce it by only 23 percent.
This problem led to the introduction of the by-catch reduction device
(BRD), a simple frame that keeps small holes open and allows small fish
to swim out of the net. The use of BRDs has significantly reduced the
amount of by-catch. There is some shrimp loss, at least 8 percent to 10
percent under the best of operating conditions, but it can be much
higher.

FERNANDINA: Birthplace of the Modern Shrimping Industry
By Helen Gordon Litrico
Men
have been catching shrimp for thousands of years, but shrimping evolved
into the modern commercial industry here in Fernandina early in this
century. The evolution was threefold: a change in location from inshore
to offshore; a change in method from cast nets, haul seines and bar
nets to the modern otter trawl; and a change in power from rowboats and
sailboats to fleets of motor-powered vessels. Here’s where shrimpers
put it all together and where the great international fleets of today had their humble beginnings.

Shrimping Pioneer Mike Salvador
_________________ |
first shipped shrimp back to New York, the selling price would barely cover express charges. At best, hIn
the early days, local shrimpers found abundant catches in surrounding
waters, operating from rowboats with cast nets around Old Town, Nassau
Sound, up and down the Amelia River and behind Cumberland Island.
Sometimes rowboats shrimped in pairs, pulling a haul seine between
them. Even small sailboats caught shrimp with bar nets.
The
first marked change in shrimping occurred in 1902, when a Sicilian
newcomer named Mike Salvador went out in deeper water over the
continental shelf, pulling a haul seine from a power-driven boat, to
increase his catch. He formed his own company in 1906 and persuaded
other Sicilians to join him - notably his two brothers-in-law,
Salvatore Versaggi and Antonio Poli, plus Joseph Gianino. Times were
poor, with
shrimp selling locally for a nickel a pound, so Versaggi
went to New York to work. There he made valuable contacts at the Fulton
Fish Market for the future distribution of shrimp before returning to
Fernandina in 1912 to found his own company. Versaggi’s start was
hardly promising. When he e would be paid off with a few postage stamps.

The modern shrimping industry began at these Fernandina docks at the turn of the century.

The
real boom in the evolution of Fernandina's shrimping industry came in
1913 when a newcomer from Massachusetts, Captain Billy Corkum, adapted
the otter trawl to catch shrimp. This is essentially the same bag-like
net with iron weighted doors which you see on shrimping boats today.
The
first power-driven boat to drag the trawl net successfully in deep
water was manned by local bar pilot Capt. William Jones Davis. Shrimp
were so plentiful then that the first crude trawls worked with great
success. In 1922, David Cook and Emmett Freeman refined the local trawl
by adding corners and wings for better operation.
As the industry’s main arena
moved to St. Augustine, Louisiana, Texas, Mexico, Tortugas, Campeche,
the Caribbean and South America, Fernandina contributed another
important name - Harry F. Sahlman. He pioneered exploratory fishing for
Royal Red shrimp in 200-fathom waters, was among the first in opening
up Campeche fishing in the
|
1940s, and provided the major political expertise in opening up South American fishing grounds.
The
founding of the modern shrimping industry was an international effort.
More Sicilians followed the pioneers - Bassetta, Litrico, Fazio, Serra
and others. There were Portugese (notably the Carinas brothers and Matt
Roland), Scandinavians (Johnson, Janson, Hansen, Olsen and Sundeman),
Greeks (the Deonas and Tiliakos boat-builders), Louis Hirth from
Germany, John Ferguson from Scotland and Dave Tapper from Nova Scotia.Many
native families were industry pioneers, too - Hardee, Cook, Lucas,
Brazzell, Little, Freeman, Wilder, Evatt, Bennett, Burbank, Garenflo,
Smith, Merrow, Davenport, Brooks, Fisher, Kelly, Clark, Goffin, Morse
and others. Outstanding among the native pioneers were the Hardee
brothers, who from 1900 operated a ship's chandlery which evolved into
Standard Marine Supply Corp. Today, through affiliated companies,
Standard Marine provides shrimping gear all
