In addition to funding research, education, and outreach projects advanced
by the nation's 30 Sea Grant progams, NOAA's National
Sea Grant College Program also awards competitive research grants
in major priority issue areas critical to U.S. waters and coasts.
Delaware Sea Grant recently successfully competed and was awarded funding
for the following projects:

Nuclear worms are large, pink, semi-aquatic polychaetes imported from
Vietnam and sold as fish bait. Import and sale of this species is unregulated
and has received much media attention recently focused on the worms’
vivid coloration, unusual size (up to 2 m long), and the potential exposure
of fisherman to pathogens associated with packing material.
"While many believe the nuclear worm poses little environmental
risk to temperate coastlines, this assertion is lacking any rigorous
scientific basis, and certainly is not a valid extrapolation to warmer,
subtropical regions of the U.S. coast," says Doug Miller, an oceanographer
at the UD College of Marine Studies.
In this study funded by the National Sea Grant Aquatic Nuisance Species
Program, Miller and John Ewart, aquaculture specialist for the UD Sea
Grant Marine Advisory Service, will conduct laboratory experiments to
evaluate the risk of survival and establishment of nuclear worms in
Mid-Atlantic waters and particularly in states farther south where warmer
subtropical climates are found. Temperature and salinity experiments
will be conducted in the first year. In the second year, the scientists
will conduct aquarium experiments at optimal temperature and salinity
to identify species of freshwater and estuarine invertebrates consumed
as prey, the worm’s ability to regenerate when cut for bait, and
their reproductive seasonality and success (if any) in the lab. Coastline
regions at risk for nuclear-worm establishment (i.e., with tolerable
temperature regimes) will be identified using electronically available
temperature data. This approach also will be assessed for application
to other tropical imported and invasive species.
The scientists will share their research findings with the public through
Web pages, a fact sheet, and lectures. The project should benefit a
range of audiences, from federal agencies, state resource managers,
and invasive species working groups, to bait shop owners and local fishermen.

This regional proposal expands on existing efforts to develop K–12
and informal science education and outreach activities related to invasive
species. Begun in Mississippi and Alabama as a two-state project with
funding from the Environmental Protection Agency Gulf of Mexico Program,
the Southeast Regional Network expanded with further fiscal support
to include the four-state region from Louisiana to Florida on the northern
Gulf of Mexico coast. This proposal refines the regional approach and
begins the process of piloting the previous accomplishments into a second
region of the country through further collaborative activities.
Specifically, the principal investigators will implement six formal
workshops on aquatic nuisance species for classroom teachers; 15 informal,
short-duration, and school-based workshops for teachers and students;
and two to four workshops for informal science educators and/or extension
agents. They also will implement a structured communications system
via the Internet for sharing information, ideas, and curricular materials
among the workshop participants. Upon completion of this phase of the
program, a total of 540 classroom teachers from Mississippi, Alabama,
Louisiana, Florida, Delaware, Maryland, and Pennsylvania will be engaged
in education-related communications to support ANS education and outreach
activities in their classrooms, along with 225 informal educators and/or
extension agents and an additional 250 policy, research, and educational
leaders from an on-line workshop.

Marine and aquatic habitats increasingly are being
threatened by non-indignenous invertebrates and algae — 298 of
these species are now documented as having invaded marine and estuarine
waters. Many aquatic nuisance species (ANS) have been transported by
ballast water, although aquaculture and the pet trades have also been
contributors to the problem. Some ANS have impacted human health with
grave effects. When Vibrio cholerae was released from ballast
water and contaminated a Peruvian drinking water system in 1991, over
a million people were infected, resulting in over 10,000 deaths. ANS
impacts on ecosystems are a major national issue, and biological invasions
are believed to be the second-largest cause of biodiversity loss after
habitat destruction. Environmental economic losses due to non-indigenous
species currently are in excess of 137 billion dollars annually in the
United States alone.
In this regional project, Sea Grant marine educators William Hall from
Delaware, Adam Frederick from Maryland, and Ann Faulds from Pennsylvania
are working to increase public education of aquatic nuisance species
through the design and implementation of two pilot ANS teacher professional
development workshops using a successful model already developed by
the Southeast ANS Education and Outreach Network. The Mid-Atlantic team
will complete six ANS professional teacher development workshops over
the next two years, reaching a total of 180 educators. The target audience
will be minority teachers and teachers of minority students who need
science certification or re-certification to continue their teaching
careers. The regional team will design evaluation materials complementary
to those that have been developed by the Southeast ANS Network, facilitating
educational research between geographic regions and meeting national
education standards. The team also will initiate a Mid-Atlantic ANS
Web site that will contain downloadable curricula and other ANS resource
materials for teachers.

The continuing decline of Atlantic oyster fisheries in the face of
the diseases MSX and Dermo has sparked a multimillion dollar effort
in the
Chesapeake Bay to revitalize the bay’s ecosystem by planting
hatchery-propagated oysters on restored oyster bottom and reefs. In
order for restoration
projects to be cost-effective, deployed hatchery oysters must show
substantially better growth and survival than wild oysters in the presence
of disease.
In this regional research project funded by the National Sea Grant
Oyster Disease Program, UD marine biologist Patrick Gaffney and colleagues
Kimberly Reece and Ryan Carnegie from the Virginia Institute of Marine
Science and Amy Wilbur from the University of North Carolina at Wilmington
will be developing a set of 100 genetic markers (single nucleotide polymorphism
markers) in the Eastern oyster (Crassostrea virginica). These
DNA-based markers should improve scientists' ability to track the survival
and reproduction of hatchery stocks in order to assess their contribution
to the local ecosystem. They also will allow breeding programs to establish
pedigree control, reducing the damage caused by inadvertent inbreeding
and contamination.
When the project is completed, all of the genetic markers will be made
available for use by researchers and resource managers via a Web data
base.
