The second oldest Federal fisheries laboratory in the United
States is located in Beaufort, North Carolina. The Center provides
managers with information needed to enhance recreational and commercial
fishing and Essential Fish Habitat information required under the
Magnuson-Stevens Fishery Management and Conservation Act. Jointly
sponsored by the National Ocean Service and National Marine Fisheries
Service, the CCFHR conducts laboratory and field research on estuarine
processes, nearshore and ocean ecosystems biological productivity,
the dynamics of coastal and reef fishery resources, and the effects
of human influences on resource productivity.
Coastal
Habitats - Research focuses on the importance of coastal
and estuarine habitats to fish, the impacts of natural and human
factors on these habitats, and how to restore them. Current studies
include salt marshes, intertidal flats, and seagrasses along the
Atlantic and Gulf coasts and large California coastal bays. The
Center also conducts studies on micro-algae, seagrass and salt marsh
plants, invertebrates and fishes, bacterial interactions, and the
linkages between habitats and all fishery organisms.
Fish
Ecology - Environmental factors affecting the survival of
the early life stages of fish need to be understood, as they are
a major factor of future populations. Larval and juvenile fish are
collected and the processes that transport larvae from spawning
to nursery grounds and the conditions which aid their survival are
described. Through otolith techniques, the ages when larval and
juvenile fish migrate to nursery grounds are also determined. This
information improves our ability to forecast abundance and manage
fish resources.
Chemical
and Physical Processes - Trace metals and stable isotopes
of carbon, nitrogen, and sulfur help researchers understand habitat
use, trophic pathways, contaminant exposure and biomagnification
in coastal ecosystems. Current projects include determining the
origin of high mercury levels in Florida Bay fish, South Atlantic
coastal pelagics, and marine mammals. Also, on the west Florida
Shelf, researchers are using isotopes to determine now much plant
productivity is needed to support a healthy system. Stock discrimination
and migration of fish are also under study using trace metal characteristics
of otoliths.
Harmful
Algal Blooms - These have been studied for more than a decade.
Understanding the conditions that produce them and detecting them
as they begin are important, as well as determining the physical
aspects of a bloom. On the west Florida continental shelf, there
are studies of how the toxins from a bloom affect the web of life.
Equipment is being developed to monitor a bloom as it develops.
Reef
Fish - Populations of snappers, groupers, and other reef
fish in the southeastern Atlantic and Gulf of Mexico are assessed
using fish landing data and life history information. The life history
data includes age/growth, mortality, and reproduction. Scientists
also analyze changes in age structure and population size of various
species, and do SCUBA surveys to study reef fish habitat distribution
and abundance, habitat preference, community structure, and impacts
of fishing on natural reefs. Summary reports are provided to regional
fish management councils and commissions discussing the health of
the populations and recommendations on ways to allow continued public
use of reef fish resources.
Population
Dynamics - Valuable commercial and recreational fish in the
Atlantic and Gulf of Mexico are monitored to gather accurate population
data. Data and statistics are provided to the Atlantic/Gulf of Mexico
Fishery Management Councils and the National Marine Fisheries Service
for their decisions. The Center also assists other institutions
with fish assessments as requested.
Protected
Species - The Endangered Species Act and Marine Mammal Protection
Act require monitoring of protected sea turtles and marine mammals.
Information gathered includes overall characteristics (e.g., age,
sex) genetic structure, habitat requirements, and navigational cues.
Also assessed are impacts of fish interactions.
