Grant Research Projects Receive Nearly $600,000 In GOIP Grants
Sea Grant College Program research projects have been awarded
$591,073 in Gulf Oyster Industry Program (GOIP) grants.
AgCenter Assistant Professor Jerome La Peyre was awarded
$192,126 for a project titled “Increasing the Survival
and Shelf Life of Gulf Coast Oysters by Controlling Their
Exposure to Air: Potential Role of Stress Proteins.”
La Peyre will study the effect of air exposure on oyster
survival during the growing period and on oyster shelf life
after harvest. Increasing the survival rate of air-exposed
oysters would have advantages in growing market-sized oysters
in shallow waters. Increasing live oyster shelf life in
late summer, when the shelf life is shortest, would have
positive distribution and marketing implications.
Peyre also was awarded $151,329 for a project titled “Effects
of Freshwater Diversions: An Experimental Determination
of the Effects of Freshets on the Oyster Parasite Perkinsus
marinus and Its Host, Crassostrea virginica.”
A freshet is a stream of fresh water that empties into a
body of salt water. Decreasing sea water salinity is known
to delay development of the P. marinus infection.
The goal of the project is to determine how various controlled
exposures to fresh water impact the intensity of P. marinus
infection in oysters.
AgCenter Aquaculture Research Center Professor Terrence
Tiersch was awarded $153,080 for a project titled “Process
Control Technology for Spawning of Triploid Females to Produce
Tetraploid Oysters.” Typically, plants and animals
have two sets of chromosomes (diploid). Triploid refers
to a genetic condition in which there are three sets of
chromosomes, and tetraploid organisms have four sets of
chromosomes. Triploid oysters are more marketable because
they grow faster, bigger and meatier than diploid oysters,
but triploids are less fertile and typically are spawned
through artifcial means. Tetraploid oysters, which are not
marketed for consumption, naturally spawn triploids which
make them excellent triploid broodstock. The project's goal
is to develop a new system to enhance triploid fertility
in order to provide eggs for tetraploid production in the
Gulf of Mexico region. Co-investigators on the project include
Steven Hall, LSU AgCenter assistant professor of biological
and agricultural engineering, and John Supan, Louisiana
Sea Grant research professor.
Janes, LSU AgCenter assistant professor of food sciences,
was awarded $94, 538 for a project titled “Detection
of Vibrio vulnificus by Direct Colony Immunoblot.”
Vibrio vulnificus is a bacterium in the same family
as those that cause cholera. It can infect oysters and can
cause disease in people who eat contaminated seafood. The
project's goal is to develop a simple, inexpensive and rapid
method for V. vulnificus detection in raw oysters
harvested from the Gulf of Mexico.
was created in 1999 by the Gulf Oyster Council, a cross-section
of Gulf oyster industry leaders, state resource managers and
academic researchers. The goal of GIOP is to encourage multi-disciplinary
research and extension projects that contribute directly to
the efficiency and profitability of oyster-related businesses
and to the safety of oyster products.
its establishment in 1968, Louisiana Sea Grant has worked
to promote stewardship of the state's coastal resources through
a combination of research, education and outreach programs
critical to the cultural, economic and environmental health
of Louisiana's coastal zone. Louisiana Sea Grant, based at
Louisiana State University, is part of the National Sea Grant
Program, a network of 30 programs in each of the U.S. coastal
and Great Lakes states and Puerto Rico/U.S. Virgin Islands.
