for Florida Aquaculture

On October 16, the Aqua
culture review Council
(ARC), an advisory council
to the Commissioner of
Agriculture Bob Crawford,
drafted a list of recommen-
dations forfunding priorities
for Florida aquaculture.
Now that the list is com-
plete, "it's up to the various
aquaculture commodity
groups to find funding
sources for their research
priorities in this next Legis-
lative session-by incorpo-
rating the proposed costs
into the annual budgets of
state universities, the
Department of Agriculture
and Consumer Services
and other agencies," says
Joanne McNeely, Bureau
Chief of Seafood and
Aquaculture/Florida Depart-
ment of Agriculture and
Consumer Services
"Because so much of the
funding is dependent on leg-
islative action, it's very impor-
tant that aquaculturists com-
municate and work with their

legislators." Joanne also
noted that while funds total-
ing $250,000 were made
available in 1996, therewere
no funds appropriated in the
1997 legislative session.
The following is an
inventory of the proposed
research priorities for 1998-
1999, listed alphabetically
by commodity groups and
ranked according to priority.
The same list has already
been sent to the Governor's
office and the Legislature.

1) Identifying factors con-
tributing to hide and leather
quality problems, to improve
the international competi-
tiveness of American alliga-
tor skins.
2) Maintaining egg quality
on public lakes that are
used by alligator farmers for
egg collection.
3) Identification of disease
outbreaks on Florida alligator
4) Marketing and promotion
to develop new markets.

Aquatic Plant
1) Research to increase
the number of pesticides
labeled for use in controlling
2) Research to determine
the nutritional needs of
aquatic plants.
3) Research to determine
production methods of new
plants not presently being

Commercial Fishing
1) Classification of as many,
or all, of the unclassified
state waters.
2) Reduction of restrictions
on shellfish harvest to
cooler time which is
currently causing Florida
shellfish to have a poor
shelf life.

Student Involvement at UF

Undergradate and graduate students are an important part of the teaching, research,
and extension programs at the University of Florida. Involvement of individual students
in these programs will be highlighted in each issue of WaterWorks.

Philip Fowler was born in
Bethesda, Maryland and
grew up in Auburn, Ala-
bama and Key West,
Florida. He attended the
United States Merchant
Marine Academy, Florida
Keys Community College,
and Tennessee Techno-
logical University. In 1978
he received a Bachelor of
Science degree in Agricul-
tural Engineering from the
University of Florida.
Upon graduation, he
returned to Key West and
ran an owner/operator
charter boat and dive busi-
ness and also worked as a
boat/finish carpenter -
building boats and remod-
eling houses in a self run
carpentry business.
In 1990, Phil returned to
the University of Florida to
pursue a Master of Engi-
neering in the Agricultural
and Biological Engineering
Department. He developed
the software package "An
Expert System in Urban
Forestry" under the super-
vision of Dr. Howard Beck.
After this, he wentonto
pursue a Doctorof Philoso-
phy in the Agricultural and
Biological Engineering
Department under the
supervision of Dr. Ray

Aquaculture was chosen
because of its dynamic
parameters and harsh
environment for electronic
sensors and mechanical
equipment. Also, the fish's
environment requires
constant monitoring and
control to maintain quality.
The control system
consisted of three micro-
controller units linked to a PC
for operator interaction. The
microcontrollers controlled
waterflowrate, air pumps and
heaters and operated a
waste removal settling filter.
A microcontroller is a
complete computeron a chip
-with its own CPU,
memo ry, input/output-and
operates the system
independently of the PC.
The PC was used only as
an operator interface to

call an operator if system
components did not
operate properly. The
system was run under
varying conditions for
approximately four
months and tested for
failure modes.It re-
sponded properly to
component failures and
showed excellent ability to
adjust to the dynamic
environmental changes.
Phil's work demon-
strates the practicality of
using microcontrolled
systems to grow fish.
Previous computer con-
trols have been expensive
and have not operated re-
liably when used in the
damp and electrically
noisy environments used
for aquaculture production.
Today micro-control-
lers are used in many
applications such as
appliances, auto-focus
cameras, and environ-
mental control in homes
and businesses.
The cost of micro-
controllers has dropped
rapidly during the 1990s
and is expected to
continue to drop, making
microcontrolled systems
a practical option for
control of recirculating
aquacultural systems.
Phil successfully
defended his PhD disser-
tation this summer and
has accepted a position
with Dynamac Corp, a
NASA subcontractor at
the Kennedy Space
Center. He will work in the
Life Support Division of
the Space Shuttle and
Space Station Projects.

Regulatory and Financial Assistance for Florida


Florida's Department ofAgriculture and Consumer Sercies (DACS) is now the primary agency responsiblefor i, h 1,,,, i
aquaculture in the state. However there are other agencies involved in the process. The following is a list of the agencies
involved in various aspects ofaquaculture pI i ,,in, :., as well as those that provide financial guidance/assistance.

Requlatorv Assistance Bureau of Marine Resources and

Bureau of Seafood and Aquaculture
The Bureau is the first agency you should con-
tact if you're interested in participating in any kind
of aquaculture activities as it is now the primary
agency for all environmental permit applications.
The bureau has assumed environmental assis-
tance responsibilities and is in the process of
developing a series of Best Management
Practices to replace environmental permitting.
All aquaculturists must contact the bureau to
obtain an Aquaculture Certificate of Registration.

guarantees with existing financial institutions.
Unfortunately, programs and funding levels
change frequently and we are listing sources of
information and not program descriptions. You
may also wish to contact regional planning coun-

well as Congressional
offices of Representatives
Steam, Boyd and Thurman.
Senators George Kirkpatrick
and John Laurent, were also
in attendance. The following
information was presented:
* A letter from David S.

ing his interest in the
commercialization of
sturgeon in Florida. David
serves on the congressional
Subcommittee on Fisheries
Conservation, Wildlife and
* Mark Berrigan, with the

(DACS). The report was
prepared cooperatively by

Mr. Zajicek, and Deborah
Britt and Dr. Andrew Lazur,
UF/IFAS Mitchell Aquacul-
ture Demonstration Farm in
This report made it clear
that Florida is an ideal
market for the introduction
of new products such as
cultured sturgeon and that
sturgeon caviar is "truly in-
ternational in its production
and consumption. The vol-
ume and value of imported
product exhibits a strong
growth trend."
* A second marketing pre-
sentation was given by Mr.
Mats Engstrom, President
of California Sunshine Fine
Foods-one of the top
suppliers of caviar on the
international market and
producers of Tsar Nicoulai
Caviar, a California-grown
aquaculture product.
Before the meeting was
adjourned, Mark Berrigan,
Environmental Administrator
with the DEP, was charged
with preparation of the final
report in response to com-
ments by the Working Group,
other state and federal agen-
cies and meeting attendees.
The plan will come under
review once more at the next

Aquaculture in Miami-
Dade County primarily
consists of freshwater
ornamental fish for the
home aquarium. Most of the
fish produced belong to the
Cichlid family and come
from Africa's Malawi and
Tanganyika lakes.
These fish were brought
to the Miami aquaculture
industry some years ago.
Fish are grown-out in both
ponds and above-ground
tanks and are fed commer-
cial diets oron farm mixtures.
Currently, there are
approximately 20 individuals
producing ornamental fish on
5-acre parcels with an
estimated farm gate value of
$3 million.
In an effort to address the
growing needs of the Miami-
Dade County aquaculture
community, the Miami-Dade
Aquaculture Advisory
Council was established this
summer. The purpose of the
council is to help define and
prioritize the community's
needs as it relates to aquac-
ulture production with the
hope that these needs can be
addressed through extension

Interest in sturgeon culture
in Florida is steadily building
due to its high value for both
meat and caviar. Florida has
three native species/subspe-
cies the Gulf of Mexico,
shortnose, and Atlantic-with
most of the recent research
focusing on life history and
induced spawning techniques
for Gulf of Mexico and
shortnose sturgeon. Within
the past several years
research efforts have
expanded into investigating
culture techniques and
evaluating fish performance.
A Gulf of Mexico sturgeon

culture research projectwas
initiated this July and is inves-
tigating the production and
economic feasibility of two
commercial scale production
One of the treatments
utilizes flow-through well
water at three exchanges per
day and the other treatment
utilizes recirculated pond
water. The recirculating pond
water system is designed to
reduce water requirements,
take advantage of the
pond's natural plankton
biofiltration, and allow for
zero discharge. Both treat-
ments consist of three 20-
foot diameter fiberglass
tanks supplied with airlifts
and airstone aeration.
Oxygen will be supple-
mented later in the 16-month
studywhen fish biomass and
feeding rates exceed
airstone oxygen transfer
capabilities. Each tank was
stocked with 400 three
month old fingerlings (6.5g)
which are expected to reach
8 10 Ibs by the end of the
Fish growth, water qual-
ity, facility infrastructure and
operating costs are being
monitored and a comparison
between the two systems
completed. In addition,
monthly effluent analysis is
being conducted from the
flow-through tanks.
Data from July to Sep-
tember in the above study
have shown slower fish
growth in the pond water
recirculating treatment
where water temperatures
have been averaging 10
degrees F higher than
the well waterflow-through
system. In order to more
clearly evaluate the effect
of water temperature on
Gulf of Mexico sturgeon
growth, another project will
begin in October.
In this study, six month old
fingerlings will be cultured for

10 weeks in four water tem-
peratures ranging from 70 to
85 degrees F.

current sturgeon research
projects at the farm, call Andy

to complete a brief question-
naire that solicited opinions
about this non-traditional
seafood product.
With few exceptions,
most surveys indicated a
high degree of satisfaction

Debbie Britand a willingness to pur-
50/674-3184 chase the product again,
although a number of
respondents expressed
initial trepidation at the
thought of eating a whole
scallop. This suggests that a
latent market for whole bay
scallops exists in north cen-
tral Florida.
A final component of the
study will be an assessment

The second harvest
season for the Florida Sea
Grant funded bay scallop
(Argopecten irradians) cul-
ture project is drawing to a
close. The final harvest
occurred October 30 from the
lease site located several
miles into the Gulf of Mexico
from the mouth of the
Crystal River. Seed scallops
grown at the University of
South Florida were trans-
planted from the St. Peters-
burg hatchery to the lease
site in early summer.
The scallops were then
grown out to market size (40-
45 mm shell height) in cages
located at the lease site.
Growout requires about six
months. Market-sized scallops
were then delivered to select
area restaurants for market
testing in whole form.
This year, as well as during
1997, market-sized cultured
bay scallops were provided at
no cost to a very select group
of white-table cloth restaurants
in Inglis, Cedar Key, and
Chefs were asked to pre-
pare the product in any
manner they wished, as long
as the product was cooked
and presented to the patron in
whole form. Patrons who
ordered the appetizer, entree,
or side dish were then asked

of the economicfeasibility of
the cultured process on a
small, commercial scale. The
analysis will consider several
growout techniques and
utilize information from
existing markets in the north-
east US, as well as Virginia
where similar research has
been conducted.
Culturing bay scallops for
the meat alone would likely
not be economically feasible
given the large volumes of
imported scallop meats.
Although the technology
required to produce seed
scallops is fairly standard (i.e.
very similar to that utilized for
hard clams), the most appro-
priate growout technology is
under development.
The market potential for
a shell-stock, cultured bay
scallop to be consumed
whole is notfully understood.
Currently, commercial
harvest and sale of wild, bay
scallops is not allowed in
Florida. However, similar
regulations in the northeast
US have been modified to
allow the sale of cultured bay
scallops. Bay scallop culture
may eventually provide a
means by which existing
hard clam growers in Florida
can diversify.

for funding. The Tropical
Aquaculture commodity
group cited the following
research needsfor1998-99:

1 Special local needs permit
for Dylox for use in commer-
cial tropical fish production
2 FDA approval of oxy tetra
cycline for use in ornamental
3 FDA approval of metron-
idazole for use in ornamen-
tal fish;
4 New species production
such as clown loach and
fancy guppies;
5 Water quality manage-
ment and conservation to
include research on recircu-
lating aquaculture systems;
6 Marketing and education
to expand awareness and
popularity of ornamental
fish among children.

* That same afternoon, the
second meeting of the
Technical Advisory Commit-
tee was held to begin
drafting Best Management
Practices (BMPs) to be
used by aquaculturists-as
part of the newly adopted
aquaculture certification

Tax Exemption for Fish


Along with making changes to the aquacul-
ture permitting process, the last Legislative
session also passed into law a bill that provides
sales tax exemption status for fish farmers
(Senate Bill 1692).
The legislation amended Chapter 212 of the
Florida Statutes and provides fish farmers the same
sales tax exemption status as other farmers
including exemptions on:
+ agriculture commodities (horticultural, aquac-
ultural, poultry and farm products, livestock and
livestock products);
+ livestock, which now includes fish raised for
commercial purposes;
+ self-propelled farm equipment ;
+ power-drawn farm equipment; and
+ power-driven farm equipment.
These legislative changes took effect on July
1 and should resolve sales tax issues that have
plagued the fish farming industry. However, it
may take some time before the various revenue
field offices are aware of the new law. If a farmer -
encounters a problem, he/she should contact
the Florida Aquaculture Association (FAA)
office to obtain a copy of the new legislation. For
more information contact: "

Interim Measures for

Aquaculture Permitting

As reported in the previous issue of WaterWorks, the last
legislative session transferred most aquaculture permitting anc
regulatory responsibilities to the Florida Department of Agricl
and Consumer Services(DACS). As a result, newly created

Aquaculture Certificates will:

* replace General Fish Farm Permits which have,
until now, been required from the Florida Depart-
ment of Environmental Protection;
* replace the Resident Fish Dealer's License from
the Florida Game and Fresh Water Fish Commis-
sion (GFC); and
* address the Environmental Resource Permitfrom
the water management districts.

Instead of permitting based on the traditional
regulatory rule, Best Management Practices
(BMPs), which are in the process of being
developed, will address the concerns of all the
agencies. If a farm can demonstrate that they
are employing the appropriate BMPs, they will
be certified by DACS.
However, the development of BMPs is going
to take a while. It has been suggested that dur-
ing the interim, farms operating under a current
General Fish Farm Permit adopt their existing
permit rules as BMPs-a relatively easy way to
become certified. However, there are many other
forms of aquaculture that do not have existing

general fish farm permit rules to work under.
To accommodate these situations, DACS has:

1 Formed a Technical Advisory Committees (TAC)
for the various commodity groups to assist in the
development of BMPs, including representatives
from industry, research, and other agencies
2 Proposed legislation which will allowforfarms
operating within existing rules and authoriza-
tions to be certified until BMPs are developed.
A Technical Advisory Committee meeting, the
second so far, was held at the Tropical Aquacul-
ture Laboratory on October 16 and demonstrated
a cooperative atmosphere. A third meeting is
scheduled for November 18. (See Calendar of
Events on page 7 for details.)
All aquaculturists are encouraged to participate
by communicating ideas and concerns to their
industry representatives. For more information

Fee Fishing in Flori ,

waters, many anglers are looking for
alternative places to fish. Fee fishing can
provide just that- particularly foranglers
seeking particular species such as large-
mouth bass or trophy bluegill. Fee fish-
ing is attractive to youth, tourists, anglers
who don't own a boat, or individuals that
fish infrequently as no license is required 4,.
S. to fish in most fee-fishing ponds.

Fee Fishing in Florida, Extension Circular 809, provides a comprehensive guide to the different types of fee fishing
operations in Florida, the economics of fee fishing operations, as well as step-by-step instructions on how to set up a fee
fishing operation. The UF/IFAS Cooperative Extension service offers a large selection of educational publications and
videos on aquaculture and pond management. To obtain a free copy of Fee Fishing In Florida or other publications,*

Sturgeon Research A National Initiative

Recent efforts by California and Florida
Sea Grant programs to develop a national
initiative for funding sturgeon research in the
United States is proving to be timely, accord-
ing to reports from the Volga River in Russia.
In an issue of Newsweek,* published
earlier this year, writer Owen Matthews
reports a growing concern, internationally, for
the shrinking availability of Russian sturgeon
roe (caviar). For years Russia has been the
main source of caviar to the international
Matthews reports, "Caviar is big business
- but a dwindling one. So many sturgeon
are being poached out of the Volga and the
Caspian Sea that next year could be the last
caviar-production season for up to a decade.
Sturgeon take nine to 15 years to mature and
the stocks of adult fish have dwindled to
almost nothing. Though Russian government-
funded fish farms release 50 million baby stur-
geon into the Caspian every year, most are
caught before they grow up and spawn.
Catches have fallen by 90 percent during the
past decade to just over 60 tons of caviar per
With seven indigenous species of sturgeon
in U.S. waters, such news has added a sense
of urgency to U.S. scientists' search for
sturgeon research funding. Workshops
designed to raise awareness about these
ancientfish, as well as encourage a national

research initiative, were organized this year.
Interested state Sea Grant programs were asked
to sponsor scientists, from their funding jurisdic-
tion, to participate in these workshops.
One such workshop was held here at UF in
March. A total of 36 scientists representing 14
states and the District of Columbia participated.

The first day of the workshop consisted of
four presentations and general discussion in-
cluding the following speakers:
Donald Campton, US Fish and Wildlife,
presented an overview of our present under-
standing of evolution and systematics of North
American sturgeon;
Dr. John Boreman, National Marine Fish
series Service, discussed mechanisms for pro
section and restoration of impacted fish popu
lations in the U.S.;
S*Dr. Serge Doroshov, University of Califor
nia at Davis, presented a paper discussing
the biological characteristics of sturgeon; and
Dr. Charles Adams, University of Florida,
discussed the husbandry and economics of
On the second day, participants were
divided into three groups representing the
following areas of study: systematics, evolu-
tion and population genetics; experimental
culture and aquaculture; protection and res-
toration. Each group was charged with the
development of a list of research needs.
A written research initiative is now being
drafted jointly by UF/IFAS and University of
California at Davis Sea Grant programs and
will be available by the new year.
