SEA GRANT RESEARCH NEWS:
Bovine Hormone Could Provide Boost to Tilapia Aquaculture
In collaboration with Monsanto Chemical Company and California Sea
Grant, Hawaii Sea Grant Director Gordon Grau is characterizing the efficacy
and safety of Monsanto's recombinant bovine growth hormone in raising aquacultured
tilapia. His research will help gather information essential for determining
whether this hormone has practical value in improving production and in
reducing costs in the aquaculture of finish and shellfish.
Grau's laboratory has established the recombinant bovine growth hormone
does have significant growth-promoting effects in tilapia. The studies
indicate the recombinant bovine growth hormone may have considerable practical
value in tilapia aquaculture, and studies are now aiming at developing
a practical method for treatment of tilapia fry.

Researchers Forecast Best Beach Nourishment Sand Dredging Sites
Sea Grant researchers say they can predict the physical impacts of
dredging the ocean bottom for nourishment sand that is used to build up
eroded coastal beaches. The key lies in finding the best location to dredge.
There are three major considerations: 1) A location close enough to the targeted beach to be economically feasible; 2) Nourishment sand must be a suitable grain size, at least as coarse as the native beach; and 3) Nourishment sand has to be sufficiently distant from the shore so that its removal doesn't modify currents and waves which could make the existing erosion process worse. Biological impacts have to be considered as well.
Paul Work, a South Carolina Sea Grant researcher at Georgia Tech Regional Engineering Program in Savannah, and George Voulgaris of the University of South Carolina have teamed up with their students to develop computer models for prediction of the physical impacts of offshore dredging on nearby beaches. They have modeled currents and waves and how they are altered by dredging. They have also compared the model results to actual field measurements of nearshore waves and currents. Three potential dredge sites near Folly Beach, SC have been evaluated for impacts. Folley Beach was last nourished in 1993 by the U.S. Army Corps of Engineers and that effort had a predicted design lifetime of eight years. No funding has yet been identified to renourish the beach, but according to the Corps schedule it is overdue.
Works' research team waits to see if dredging at one of the Folly Beach
sites occurs and what the actual results are. If the model predictions
and reality correspond, then this approach could be applied to other coastal
beach nourishment projects yielding better predictions of impacts and optimization
of mining locations.

Timely Publication from Delaware Sea Grant on Port Security
The Delaware Sea Grant College Program has just issued a timely publication
as the United States seeks to improve homeland security. Entitled
"Port Security for the United States" the 80-page book is a collection
of research essays looking at: 1) the vulnerability of US ports and harbors;
2) measures that can be taken to strengthen their security; 3)the interaction
between the various agencies at the federal, state and local levels in
establishing port security; and 4) the various legislative solutions proposed.
The book is edited by University of Delaware Professor of International
and Maritime Law Gerard J. Mangone who believes no avenue is more open
to terrorism than American seaports.

SEA GRANT PEOPLE IN THE NEWS:
Longtime North Carolina Sea Grant education specialist Lundie Spence
has left that position after more than 20 years. Starting this month Spence
will become director of the Southeast Center for Ocean Science Education
Excellence program (COSEE) in Charleston, S.C. COSEE will foster collaborations
between ocean science researchers and educators, and translate the research
into high-quality education programs. The Southeast center is one of seven
regional centers in the United States in a five-year educational project
that is directed by the National Science Foundation with additional funding
and administrative support from NOAA's Office of Education.
SEA GRANT WEB SPOTLIGHT:
The Bridge - Ocean Science Educational Teacher
Resource Center
http://www.vims.edu/bridge/
Teachers will find a selection of the best online resources for ocean
sciences education. Site goals are to provide educators with content-correct
and content-current marine information and data; to support researchers
in outreach efforts; to improve communications among educators and between
the education and research communities. All information and links
featured on "The Bridge" is screened by scientists and educators. New material
will be added regularly. "The Bridge" is supported by the National Oceanographic
Partnership Program, and is sponsored by the National Marine Educators
Association and the national network of NOAA's Sea Grant College Program
educators.
