The Big Picture: International and
National Aquatic Health

For many years, the federal government
has been working toward development
of national programs and guidelines
to align the U.S. with current thinking
and procedures developed by the
international community. The OIE
(World Organization for Animal
Health) animal health guidelines have
been adopted in one form or another
by many World Trade Organization
(WTO) members, and are intended to
promote safe and open international
trade of animals and animal products.
Failure to follow these guidelines could
result in economic barriers to trade
for Florida producers. In 2001, the
Joint Sub-Committee on Aquaculture
directed three federal agencies
(Agriculture-USDA, Interior-Fish and
Wildlife Service, and Commerce-
NOAA Fisheries) to establish a National
Aquatic Animal Health Task Force to
draft a National Aquatic Animal Health
Plan (NAAHP). Although infectious
diseases are typically caused by
bacteria, parasites, fungi or viruses,
most international diseases of concern
are viral diseases, because these are the
most difficult to treat and control.

Ornamentals: Spring Viremia of
Carp Disease

when an internationally reportable disease,
Spring Viremia of Carp (SVC), was officially
documented in a North Carolina koi carp
production facility. SVC is a viral disease, first
described in Europe, which can cause up to
70% mortality in koi carp and related fish
species.

This disease had serious implications for the
industry. Koi carp are an important ornamental
fish species, commonly kept in water garden
ponds. They are the colorful strain of common
carp, an important food fish in many parts of
the world which had also become introduced
as a non-native species in some waterways
of the U.S. Because SVC was considered a
disease exotic to the U.S. and no plans for
managing introduction had been formulated,
all the production facilities owned by the
farm in North Carolina were placed under
quarantine, stopping business for a multi-
million dollar company for a year.

Faculty members in the UF/IFAS Department
of Fisheries and Aquatic Sciences (FAS) and the
College of Veterinary Medicine (CVM) assisted
industry in resolving this issue through work
with the National Aquaculture Association
and the USDA. Faculty coordinated producer
educational sessions throughout the state and
they produced an outreach fact sheet (http://
edis.ifas.ufl.edu/VM106) that was widely
circulated to the aquaculture industry. All koi
on the facilities in North Carolina were killed
and disposed of and new bi-security protocols
were implemented.

The USDA now conducts a voluntary SVC
surveillance program on koi and goldfish
production facilities, and thus far samples
collected from participating facilities have been
negative. Currently the USDA is developing
health certification protocols for importation
of SVC susceptible species including koi. Since
the 2002 outbreak, several members of FAS
and CVM faculty have been actively involved
in working groups organized to develop the
National Aquatic Animal Health Plan, as well
as a voluntary aquatic animal health plan for
Florida's industry.

Koi Herpes Virus Disease

Another disease of koi carp has recently


emerged. Major carp die offs in Israel and the
US in the late 90s were attributed to Koi Herpes
Virus (KHV) disease (see IFAS EDIS fact sheet at:
http://edis.ifas.ufl.edu/VM113). KHV disease can
strike quickly and result in 80-100% mortalities.
Unlike SVC, which also affects several other
species of fish, KHV is specific to koi and
common carp. And unlike SVC, which has been
studied extensively and is an internationally
reportable disease, more research is necessary
to design sensitive and standardized diagnostic
tests for KHV. Since the late 90s, KHV has been
detected in a number of states including Florida,
as well as in other countries, and has become a
controversial disease with regard to management
recommendations. Herpes virus infections
are well-known to result in a carrier state that
can thwart detection and bio-security for KHV.
Recently, UF FAS and CVM faculty worked on an
extension publication and provided educational
outreach to Florida's industry.

Diseases in Wild Fisheries: Largemouth
Bass Virus Disease

Viral diseases exist in wild fish as well as in
cultured stocks, but diseases of wild fish are
typically more difficult to study. In the early
90s, an iridovirus was isolated from clinically
healthy populations of largemouth bass in Lake
Weir, Florida. Subsequently, a blood test was
developed by FL-DACS and, together with FAS
faculty and FWC, testing was carried out at four
lakes where high percentages of largemouth
bass had been exposed to the virus. There was
no evidence of clinical disease in the tested
fish. This and subsequent research supported
the view that the virus is not disease-causing to
Florida largemouth bass.

Nevertheless, numerous studies both in wild
fisheries and controlled experiments have

ecological resources. Dr. Debra Murie's
research program focuses on providing
a fundamental link between the science
and the applied management of these
aquatic resources.

Dr. Murie specializes in various aspects
of the ecology and population biology of
coastal marine fishes, such as groupers,
grunts, sheepshead, and amberjacks.
In particular, she studies comparative
aging methods, models growth and food
consumption, estimates mortality, and
applies population dynamics to stock
assessments and fisheries management.
This is important because a critical part of
estimating the production of a stock relies

in leclieational and
commercial fisheries, and estimating
their age and growth using predictive
models, are both
key to assessing the
sustainability of the
reso urce.

As a central part of
S Dr. Murie's broader
efforts to contribute
to fisheries science and management
on a regional and national level, she is
appointed to the Finfish Stock Assessment
Panel for the Gulf of Mexico Fisheries
Management Council (GMFMC). In
conjunction with GMFMC and NOAA
Fisheries, Dr. Murie participates in
Southeast Data, Assessment, and Review
(SEDAR) committees. It is through SEDAR
Committees that the total allowable catch
or quota for each of the recreational and
commercially important fish species is
set, and their status as over-fished or not
is assigned. Dr. Murie's involvement in
these committees allows her to have a
direct impact on sustainable fisheries
and provides an integral link between
the University of Florida and fisheries
management agencies at the state and
federal levels.

Training and mentoring of both
undergraduate and graduate students
are cornerstones in the development
of highly-skilled fisheries professionals.
Dr. Murie teaches both undergraduate
and graduate courses dealing with
perspectives in fisheries and biology
of fishes. In 1998, Debra spearheaded
the development of an annual graduate
student symposium, where all graduate
students in the Department of Fisheries
and Aquatic Sciences present their


research proposals or part of their
completed research during a two-day
conference. The continuing goals of the
symposium are to foster the development
of high caliber, effective oral and visual
communication skills in graduate
students, to provide a venue for students
to develop theirs skills and work as ateam
through organizing and conducting the
symposium, and to provide opportunities
to develop critical thinking skills. The
benefits of this Symposium have been far-
reaching, including students presenting
and winning awards at national and
international conferences.

ent Spotlight


Annual rises in atmospheric carbon dioxide
(CO2) have generated worldwide concerns
because increases in atmospheric CO2
contribute to what we know as the greenhouse
effect, or warming of the earth's atmosphere
(global warming). Much of the focus to date has
been on additions of CO2 coming from human
activities, but there are natural sources of CO2
to the atmosphere. The atmosphere, terrestrial
biosphere, oceans, and
sediments all serve as
carbon reservoirs.

The carbon reservoirs
are connected through
pathways of exchange
regulated by various
geochemical processes.
Because freshwater only
covers about 2% of the
earth's surface, many
scientists have lumped
inland freshwater
systems (lakes, rivers,
streams, and reservoirs)
with the terrestrial biosphere, or ignored these
carbon reservoirs all together, disregarding them
as simple pathways to another reservoir. Recent
research by Bower and McCorkle 1980, Kling et
al. 1991, Hesslein et al. 1991, Cole et al. 1994,
1998, and Prairie et al. 2002, however, indicated
lakes could be an important source of CO2 to the
atmosphere.

The state of Florida has an extensive group of
water bodies. The state has over 7, 700 freshwater
lakes, covering approximately 6% of the states'
surface (Florida Aquatic Habitat and Fishery Resources).
Lakes range from low to high productivity, having
various sediment and chemical compositions.
My research was developed to determine how
many lakes might be a source of CO2 to the
atmosphere. I also attempted to examine which

oi (\el 600 lakes ,IdstlI)uted
throughout the state of
Florida, I found that over 80% of the lakes
examined are sources of CO to the atmosphere.
This preliminary research suggests, as found
by Cole et al. 1994, that lakes should not be
ignored as carbon sources to the atmosphere.
I also found significant correlations between
CO2 and calcium concentrations, true color
levels, and chlorophyll (an index of algal
biomass) concentrations. The importance
of these environmental
correlations, if any, is being
investigated further.

I am also investigating
the impact of aquatic
macrophytes on a lake's
ability to release CO2 to the
atmosphere. The presence
of aquatic macrophytes
and their subsequent effect
on CO2 levels has not yet
been investigated. My
study site is Orange Lake.
This 13,000-acre lake is
located in Alachua County
and has extensive regions of various aquatic
plants. Plant sites were chosen to include
submergent, emergent, and floating vegetation,
along with an open water site. Carbon Dioxide
levels were measured over a 24-hour period
once monthly during the summer 2005 season.
The data will help to distinguish what effect if
any, aquatic plants have on CO2 levels within
the lake.

The results of my studies have implications
both statewide and globally. Assessing the level
of CO2 outgassing from freshwater is important
to scientists trying to construct regional and
global carbon budget estimates.

research program focuses on tne ecology or tropical marine
ecosystems and the application of this information to the
marine protected areas (MPAs) design and management
and ecosystem-based management approaches to marine
conservation. Her doctoral research examined the application
of terrestrial landscape ecology principles to the design and
management of MPAs in coral reef ecosystems. As part of this
research, in collaboration with scientists at the University of
Florida, she conducted studies to examine the utility of large-
scale benthic habitat maps to predict reef fish assemblage
structure as proxies for selecting priority conservation sites.
Reef fish censuses were conducted at reefs in the US Virgin
Islands, the Florida Keys National Marine Sanctuary and the
Turks and Caicos Islands. Various reef fish parameters derived
from these data were analysed spatially in a geographic
information system to investigate the generality of MPA design
criteria.

As the National Ecologist for the National Marine Protected
Areas Center Science Institute, she plays a critical role in the
ongoing effort to design a science-based and effective system
of MPAs meeting multiple conservation and management goals
throughout the U.S. Her primary responsibilities include: (i)
developing a strong and collaborative science program targeting
key issues in the design and adaptive management of MPAs; (ii)
participating in regional, national and international scientific
working groups on important marine conservation issues; (iii)
supporting and guiding the MPAC's ongoing assessment of
the current suite of US MPAs and the identification of future
place-based conservation priorities; and (iv) evaluating and
synthesizing for broad audiences scientific issues in marine
conservation.

She is involved in several key projects to achieve these goals.
One project addresses the topic of enthic-pelagic linkages.
One of the most fundamental challenges in MPA design is
determining the extent to which extractive activities (e.g.,
fishing) should be restricted or prohibited, while maintaining
crucial ecosystem processes. Vertical zoning is a strategy that
allocates human uses to specific depth zones within the water


column; however it requires understanding of benthic-pelagic
coupling. Yet, benthic-pelagic coupling is one of the least
understood ecosystem processes, and even less is known about
how recreational fishing disrupts this coupling. To explore this
issue, NOAA's MPA Science Institute convened a workshop
of fisheries biologists, ecologists and recreational fishermen
in Monterey, CA in November 2005, which was attended by
Dr. Bill Lindberg of UF IFAS. This team concluded that under
conditions with strong benthic-pelagic coupling, the effects of
fishing on this coupling are likely to be high; therefore vertical
zoning is not recommended. Conversely, under conditions
with weak benthic-pelagic coupling, fishing effects are likely
to be low; therefore vertical zoning may be appropriate.
Specific guiding principles proposed are: 1) Vertical zoning is
not appropriate at spawning aggregations, because pelagics
congregate in large numbers in a spatially and temporally
predictable fashion. 2) Vertical zoning is appropriate in depths
greater than 100 m, and 3) Vertical zoning is not appropriate
around atolls and shallow seamounts.

Another major project is the MPA Science Integration project.
Differing scientific views and interpretations have created
confusion and concerns over the role of marine protected
areas (MPAs) in the management of the nation's fisheries and
the conservation of its marine biodiversity. Consequently,
there is an urgent need for joint ecosystem and fishery level
indicators, reference points and control rules to evaluate
the tradeoffs ecological and economic between spatial
management approaches such as MPAs and other fisheries
management strategies. To address this problem, NOAA's
National Marine Protected Areas Center-Science Institute
(NMPAC-SI) and NOAA's Southwest Fisheries Science Center
(SWFSC) lab in Santa Cruz have convened a technical
working group to develop the scientific information necessary
to integrate MPAs with conventional fisheries management
strategies. Toward this end, there are currently four teams:
1) fisheries 2) natural heritage, 3) ecological indicators and

isolated the virus, and many scientists have concluded that in
other states it might be disease-causing. There is uncertainty
as to what the exact role of the virus is in disease, and what
other factors play a role in the wild. This lack of information
on the virus pathology is a concern. All well-described, classic
veterinary diseases have a specific pathogenesis (how a
disease progresses) and specific pathologic features (defining
characteristics of the disease), that, along with disease-specific
diagnostics, readily distinguish one disease from another.
Most of the wild fish purportedly dying from largemouth bass
virus have been older individuals. However, most laboratory
studies where mortalities have occurred during challenge with
the virus have used juveniles (in general, older fish were not
affected), and pathology has been inconsistent.

Given the available information, a precautionary approach has
been taken by most agencies, including the FWC in Florida,
especially with regard to stock enhancement programs. As
an example, the FWC formed a fish health working group
including faculty from FAS for its new Largemouth Bass
Research and Conservation Center, and that group has
developed risk management recommendations for iridovirus
and other potential diseases in freshwater hatchery stocks.
Other Emerging Viruses

Other iridoviruses have caused problems in aquacultured
species nationally and worldwide. The iridoviral diseases of
commercially important finfish, including white sturgeon, red
sea bream, redfin perch, rainbow trout, and Japanese parrotfish


are more studied than others, including those described in
ornamental fish. A question that remains to be answered is
what degree of relatedness these iridoviruses have with each
other, and whether an iridovirus isolated from one species
can cause disease in another.

A relatively new group, the betanodaviruses, has become an
important cause of mortalities in cultured marine species.
Juveniles of marine food fish species in Asia, including striped
jack and tiger puffer, were among the first reported with disease
caused by these viruses. A unique feature of this group is that,
unlike most other viruses that attack organs within the body
cavity, skin or gills, betanodaviruses attack central nervous
tissue, including brain and spinal cord. A betanodaviral disease
was described for the first time in white seabass produced in
California. As the culture of marine species increases, both for
stock enhancement and for commercial food and ornamental
industries, there is a strong likelihood that this group of viruses
(or others) will increase in importance and require study.
Critical Research and Diagnostic Needs

Currently, fish disease diagnostic services in support of
the commercial aquaculture industries and wild fisheries
are available through the University of Florida, FL DACS-
Division of Animal Industry, the FWC, and other public and
private laboratories and private practitioners in the state.
These laboratories are equipped to assist with most disease
outbreaks. However, there remains a gap in the state of
Florida's diagnostic capabilities for official USDA-approved
testing of certain reportable diseases, including fish viruses.
