Food Fish


Fish farmers will be
pleased to know
that they now
have a new resource
available. Developing
Florida 'sMarine FoodFish
Industry was recently
published a report
based on two days of
deliberations by experts in
the finfish industry.
Three separate pan-
els of experts represent-
ing production, marketing
and regulation discussed
the potential to success-
fully culture and market
35 species of marine fin-
During these sessions
it was agreed that Florida
offers fish farmers sev-
eral advantages includ-
ing year-round warm
temperatures; availability
of high quality water;

ready access to local,
regional, national and
global markets; and ex-
cellent technical and
business support from
public and private
Fish identified by
workshop participants as
being the best candi-
dates should have:
* minor knowledge gaps
in production, marketing
or regulation,
* high market value,
* wide salinity tolerance,
* fast growth rate,
* been a native species,
* the capability of being
grown intensively.
Fish species that most
nearly satisfied these
criteria are red drum,
flounder, mahi-mahi,
grouper, pompano, mut-
ton snapper, sturgeon

and common snook.
The first four species
(red drum, flounder, mahi-
mahi and grouper) were
highly ranked throughout
the prioritization process.
The next four (pompano,
mutton snapper, sturgeon
and common snook) are
considered extremely
high-value products that
meet many of the critical
considerations, but fell
short because of low
scores in certain areas.
Caution is advised
when considering a new
crop species; farmers are
strongly encouraged to

Dan VanGenechten
was bom in Detroit, Michi-
gan and as soon as he
was old enough to hold a
fishing rod, he developed
a passion forthe sport and
the outdoors.
After graduating from
Chippewa Valley High
School in Mt. Clemens,
Michigan (in 1991), he
attended the University of
Michigan (UM),AnnArbor.
It was at UM that he
began to foster the idea of
fisheries biology as a ca-
reer. During those years,
Dan served as a work-
study student at the U.S.
Geological Survey's Great
Lakes Science Center.
He also worked with the
Idaho Fish and Game
Department and the
Michigan Department of
Natural Resources during
his summers.
In January, 1997, Dan
decided to pursue a gradu-
ate degree in fisheries
science, and enrolled in
UF's Department of Fish-
eries andAquatic Sciences,
Gainesville. While at UF,
Dan served as a teaching
assistantfor undergraduate
and graduate courses.
Dan has been involved
in a wide range of research
in Florida, including:
* assessment of agricul-
tural best management
practices on water qual-
ity and invertebrates;
* invertebrate monitor-
ing ofthe lower St. Johns
* relationships of juve-
nile and small fish popu-
lations to season and sa-
linity in Alligator Pass at

New Aquaculture

Division Established

Sherman Wilhelm was recently ap-
pointed as director of the newly created
Division of Aquaculture in the Florida
Department of Agriculture and Consumer
Services (FDACS).
Wilhelm joined FDACS in 1986 after
graduating with a law degree from the
University of Florida. He served as staff
counsel for Commissioner Doyle Conner
and continued in that role for Commissioner
The new division was authorized this year
by the State Legislature. It brings together
regulatory activities from both marine and
freshwater aquaculture previously
handled by DEP's Bureau of Marine
Resource Regulation and Development,
and FDACS Bureau of Seafood and Aqua-
culture, respectively. Florida now has the
largest state agency based unit in the
country, federal or otherwise, dedicated
solely to aquaculture.
"The merging of these units creates a one-
stop agency forthose involved in aquaculture,
whether saltwater or freshwater," Crawford
said. "This will greatly aid in the further de-
velopment of Florida aquaculture, which is
already one of the fastest-growing sectors in
The new Division of Aquaculture com-
bines 41 employees from the DEP bureau
involved in marine fisheries and nine
FDACS employees who were primarily
involved in compliance monitoring of fresh-
water aquaculture.
Promotion and marketing duties of all

aquaculture products will remain with the
Bureau of Seafood and Aquaculture.
The DEP Bureau of Marine Resource
Regulation and Development was involved
in testing water quality in shellfish harvest-
ing areas, replenishing oyster beds,
assessing sites for shellfish production,
inspecting shellfish processing plants, and
issuing aquaculture certificates of registra-
tion. These activities will continue within the
new Division ofAquaculture.
Compliance monitoring of freshwater
aquaculture activities, including production
of tropical fish, food fish (such as catfish),
and aquatic plants has also been assumed
by the new Division ofAquaculture.
Meanwhile, Best Management Practices
(BMPs) are being developed by FDACS for
all aquaculture producers, who will be
exempted from obtaining environmental
permits when they follow the recommended
practices. FDACS previously has been
involved in developing BMPs forforestry and
other agricultural activities.
"The new Division of Aquaculture will help
streamline the regulatory process for all
those starting or currently involved in
aquaculture activities, while ensuring
compliance with Best Management
Practices," Crawford said. "This will encour-
age more efficient development of the
industry to provide an abundant and whole-
some supply of aquaculture products for

before taking any action.
While fish farming advantages are
numerous in the Sunshine State, they are
not always sufficient in guaranteeing
success. Research and development is
crucial to the process. The industry has
tripled farm gate sales over the last ten
years and much of this success can be
attributed to the adoption of new produc-
tion techniques and the successful
culture of new species learned from
research and development projects.
The report stated that consistent state
or federal funding for integrated demon-
stration projects is needed. Collaboration
is needed to solve problems and improve
or develop production systems, such as:
* raceways
*cages and hybrid systems,
*spawning and hatchery techniques,
*micro-encapsulated feeds,
*batch plankton culture procedures,
*preventative aquatic animal health
practices and product value.

Ground-breaking for
Nutrition/ Water
Quality Laboratory
and Hatchery
As of this writing, Hills-
borough County has
selected a contractor with
the apparent low bid for
construction of the nutri-
tion lab, water quality lab,
and the experimental
hatchery. This building will
include 4,000 square feet
of enclosed, climate-con-
trolled space, and 1,200
square feet of covered
slab area for equipment
storage and a workshop.
If everything goes as
planned, construction
should be completed in
January of Y2K.
Much of the equipment
(tanks, filters, etc.) has
either been purchased or
donated (see Hartz Moun-
tain news item), and is
ready to be installed as
soon as the building is

Research Update
The Florida Tropical
Fish Farms Association
(FTFFA) recently funded
two research projects at
the Tropical Aquaculture
Laboratory on behalf of the
ornamental fish industry.
The first, entitled "Epi-
demiology of Gourami
Diseases: A Statistical
Examination of Factors
which Contribute to Low
Productivity and Disease
Outbreaks" began in July
and is designed to provide
information which will help
farmers maximize produc-
tion of gouramis.
The second, entitled

"In-vitro Culture and
Cryptobiosis in Cichlids"
will investigate important
aspects of a parasitic
disease in cichlids.

Hartz Mountain
Donates $106,000
in Equipment to TAL
The Hartz Mountain
corporation, one of the
largest companies in the
pet industry, recently
closed their facility in
Gibsonton, Florida.
Part of this facility was
a research and develop-
ment operation started by
The Wardley Corpora-
tion-now merged with
In an effort to promote
research and education
for the industry, over
$106,000 worth of equip-
ment was donated to our
facility including tanks,
aquaria, filters, power
tools, and a lot of "miscel-
laneous" items (electrical
supplies, nuts, bolts, etc.).
This kind of industry
support is key to the
success of the TAL, and
Hartz Mountain's gift is
greatly appreciated.

Use of Dimilin in
Fish Production
Ornamental fish producers
experiencing problems
with predacious or com-
petitive pests such as
glassworms, water beetles
and anchor worms may
have a new way of control-
ling the situation. It's called
Dimilin 25W, manufac-
tured by Uniroyal.
Dimilin is a synthetic,
insect growth regulator,
which inhibits the success-
ful formation of chiton, the
material used in forming

exoskeletons-the hard
outer covering of these
organisms. It was initially
approved in May, 1998 to
include control of free-swim-
ming anchor worm (Lernia)
parasites in ornamental fish
production ponds.
So, there was some
interest in seeing if Dimilin
would control various water
pests with exoskeletons.
However, there was also
concern that Dimilin would
negatively impact zoo-
plankton populations,
which often serve as the
food source for small
ornamental fish.
While a thorough, highly-
controlled experiment is still
needed to prove results,
observations from Uniroyal
indicate that treated ponds
had fewer or no pest
species, and that zoo-
plankton was only margin-
ally impacted. Six treated
ponds were compared
with six untreated ponds,
over a period of four
weeks. Zooplankton and
free-swimming inverte-
brates were compared for
presence, size and over-
all quantity, on a visual
observation basis (naked
eye and with a stereo
Based on these obser-
vations, ornamental fish
producers experiencing
problems with predacious
or competitive pests such
as those mentioned above,
may want to investigate
Dimilin as a treatment.
Dimilin is a restricted-use
pesticide, and anyone
using it is required to have
a restricted-use pesticide
applicator license to
purchase or apply it.

Internship Program
The farm is proud to
announce a new intern-
ship program, which will
provide valuable staff
support for programs
while giving intern(s) an
opportunity for technical
and hands-on experience
in a learning environment.
Pascale Nerette, a vet-
erinarian from Montreal,
Canada and Stephen
Keltz, a recent Masters
graduate from London,
England, began in July
and will work for six
months assisting in all
aspects of the farm. We're
glad to have them aboard!

Sturgeon Nutrition
Andy Lazur and Debbie
Britt Pouder recently
received grant funding for
a cooperative sturgeon
nutrition project with
Richard Miles of UF's
Dairy and Poultry
Sciences Dept. and Brian
Hickson of the U.S. Fish
and Wildlife Service's
Warm Springs Regional
Fisheries Center in Warm
Springs, Georgia.

The project will gener-
ate information on practi-
cal feeding practices for fry
and fingerlings, feeding
maintenance requirements,
and rate and effects of
yeast-based protein on
performance of native
Florida sturgeon.
Grant funding was also
received for support of
Gainesville and Blountstown's
captive, native sturgeon
broodstock program. To
evaluate lower cost and
more locally available feeds,
the farm recently concluded
a Gulf of Mexico sturgeon
feeding project comparing
standard trout feed to hybrid
striped bass and catfish
We evaluated not only
growth of the fish on the
three feeds of varying
protein and fat content, but
also feed cost per pound
of fish grown. Another
study evaluating produc-
tion and economic feasibil-
ity of Gulf of Mexico
sturgeon in two different
tank systems will be
completed in November.
Growth performance will be
evaluated, and an economic
analysis will be performed in
cooperation with Chuck
Adams and David Zimet of
UF's Dept of Food and
Resource Economics.

Cedar Key

Crop Insurance
Available for Farmers
Clam farmers in Florida
will be among the first aquac-
ulturists in the United States
to be eligible for federally
subsidized insurance for
their crops.
The Federal Crop Insur-
ance Corporation recently
approved a pilot program for
clam growers in selected
counties in Florida, South
Carolina, Virginia, and Mas-
sachusetts for the 2000
through 2002 crop years.
This culminates a year's
work conducted by the
United States Department of
Agriculture (USDA) Risk
Management Agency. It
started with an exploratory
session held at last year's
tion annual meeting in Cedar
Key, and was followed by
focus workshops and site
visits during which industry
members commented on
draft policy provisions.

"These breakthrough
programs can have a signifi-
cant economic impact on our
$138 million a year hard shell
clam industry," said August
Schumacher Jr., Under Sec-
retary for USDA Farm and
Foreign Agricultural Services.

'This action will help ensure
that clam producers are
able to secure the credit
they need to build and
expand their operations."
The pilot program will
provide financial protection
from crop losses resulting
from unavoidable damage.
The new program is simi-
lar in concept to the USDA
Farm Service Agency's
Noninsured Crop Disaster
(NAP), which is based on
the inventory value of the
crop. The key difference,
however, is that the grower
will select the amount of
coverage, ranging from 50
to 75% of the crop inven-
tory value, at 100% of the
market value.
Premiums will be deter-
mined based on the
amount of coverage
selected. In addition to the
buy-up program, cata-
strophic, or CAT coverage
will be available providing
protection for 50% of the
crop inventory value at 55%
of the market value.
Another plus for the
growers is that the CAT
program will not require a
35% area designation as
the NAP program does.
Completely subsidized
by the federal government,
catastrophic coverage can
be purchased by farmers at
a fixed administrative fee.
Clams in both the field nurs-
ery and grow-out phases,
planted in either bottom
bags or as bottom plants,
will be eligible for coverage.
Clams in the land-based
nursery phase will not be
covered in the pilot pro-
gram, butwill still be eligible
for protection under NAP.
Causes of crop loss thatwill
be insured include oxygen
depletion, disease, freeze,

hurricanes, increase or de-
crease of salinity, tidal wave,
storm surge, or windstorm.
Counties in Florida where
the pilot crop insurance pro-
gram will be initiated include
Brevard, Dixie, Levy, and
Indian River. The sales clos-
ing date for the 2000 crop
year is December 1, 1999.
Although administered by
the USDA, crop insurance is
sold and serviced by private
insurance companies. Rep-
resentatives from several
reinsured companies met in
Cedar Key last month with
USDA Risk Management
staff to review the final pro-
gram policy and actuarial
documents. Premium rates
introduced at that meeting
indicate that insurance protec-
tion will indeed be affordable.
To assist the industry in
understanding this new pro-
gram, several workshops are
scheduled (see Calender of
Events), during which USDA
staff will be available to dis-
cuss the pilot program as
well as give examples of cov-
erage, indemnity payments,
and costs.

Christopher Brooks re-
cently replaced Molly
Sandfoss as UF/IFAS'
aquaculture extension con-
tact in Miami-Dade County.
A graduate of Colorado
State University, Brooks first
worked there for Aquatic
Biosystems Inc., producing
both freshwater and saltwa-
tertoxicology test organisms.

When graduate school
beckoned, he moved to Or-
egon State University,
spending most of his time
at their research station in
Newport on the Pacific

In graduate school,
Brooks was involved in
designing and constructing
an oyster hatchery, a nurs-
ery and an outdoor
algae-raising greenhouse
complex. During that time,
his professor launched the
Molluscan Broodstock

Project, which has become
the largest of Pacific oyster
breeding programs. Much of
the work involved designing
equipment and sharing
results with the local oyster
Brooks' master's thesis
tested the feasibility of
predicting adult oyster
growth from spat growth in
the nursery, using a tide-
simulatorto condition oysters
in the lab. He also pro-
grammed a computer using
EnvironMac to adjust the
valves in a manner that
would create diurnal tide
cycles. The same system
was later used for a sturgeon
culture feasibility project.

Associate of Science
Degree in Aquaculture
Now Available
Hillsborough Community College (HCC) recently
graduated the first four students in Florida history with
an Associate of Science degree in Aquaculture.
Darlene Haverkamp, the first aquaculture stu-
dent to graduate with Honors, worked briefly this
past summer for the University of Florida's Dr. Roy
Yanong on the Cichlid Project. She also worked for
HCC as a lab assistant and on a live rock project.
She entered graduate school this fall at the Uni-
versity of South Florida in St. Petersburg, studying
aquaculture under the direction of Dr. Jose Torres
and Dr. Bill Falls.
Among the other HCC grads:
Tom Stephens is working at Segrest Farms with
Dr. Denise Petty. Tom was selected as Outstanding
Aquaculture student of 1998-'99. Paul Strazzulla is
working at Hi-Tech Fisheries of Florida, Inc. in Lake-
land, owned by Marty Tanner. JenniferAlamed now
works at 5-D Tropical Inc. rearing Corydorus catfish.
For more information about HCC'sAS Degree
Program, contact:
Dr. Bill Falls at 813/253-7881.

This has been an outstanding yearforFish-
ing For Success, with 2,553 youngsters partici-
pating so far in 1999. Some 39 different schools
and youth organizations were involved.
Perhaps the highlight event was a fishing
rodeo held at a small, neighborhood pond in
Gainesville, which local kids had earlier pre-
pared for fishing. This included
removal of excessive aquatic
weeds, a general cleanup ofthe
pond shoreline and nearshore
water, and the transportation and
stocking of 800 fish, including
many big catfish.
Local businesses including
The Tackle Box, The Heritage
Club, Albertsons and Wal-Mart,
donated prizes and food for all
52 participants. Though the day
was hot and fishing slow, the
youngsters had a great time.
Perhaps it was the pride and
work involved in preparing the
lake-and in doing so, studying
the aquatic animals and plants
that live there.
The program is a joint effort involving the
University of Florida's IFAS Department of Fish-
eries and Aquatic Sciences, Florida Fish and
Wildlife Conservation Commission, Alachua
County Sheriffs Office, and Gainesville Police
Department. Working together, they have cre-
ated FishingForSuccess-with the goal of pro-
viding aquaticsciences-related educational op-
portunities foryouth.As a result, any youth group
can now contact UF's Department of Fisheries
and Aquatic Sciences and request to partici-
pate in a variety of activities including informal
aquatic educational programs for elementary,
middle, and high school students. Groups visit
the Department to participate in one or two-
day long, hands-on environmental leading
activities such as pond ecology, aquaculture
tours, demonstrations, and fishing.
Staff and graduate students from the Depart-
ment of Fisheries and Aquatic Sciences
introduce youngsters to the world offish, aquatic
invertebrates and plants, and to various aquatic
career opportunities through academic presen-
tations and hands-on field experience.
All activities are hands-on and tailored to
the age group. Activities are designed not only
to stimulate the curiosity of the individuals, but
to show them that what they are leading in
school also applies to the real world.

Aquatic Invertebrates
Dipnets are provided to students, who collect aquatic
invertebrates from ponds at the Department. After col-
lecting foran allotted time, students gather around fora
brief aquatic ecology lesson and discussion to identify
what they have caught, the animal's biology and habits,
and their importance in the food chainAreb of a pond.

Aquatic Plants
Students collect and leam how to iden-
tify aquatic plants.They also discuss plant
biology and theirrole in aquatic ecosystems,
and learn about methods used to control
aquatic plants when they become weeds.
Introduction to Fish
Participants leam how to
collect and safely handle
fish, with some basics offish
identification and their
anatomy. In addition, they
are taught fish biology and
ecology, along with an intro-
duction to fish farming
Water Quality
Students are introduced
to water chemistry and its
importance to fish survival.
Using test kits and meters,
' ., they learn how to test the
S water for various physical
and chemical properties
such as temperature,
dissolved oxygen, and pH.
The parameters of good water quality are
taught, that will help ensure survival of
aquatic life. The youngsters also leam how
to measure water clarity using a Secchi
disc, and what factors affect water clarity.
Students are given the opportunity to
fish ponds stocked with largemouth bass,
bluegill, and channel catfish, where
chances of catching fish are very good.
Those who have never fished are taught
angler ethics and safety, and basic angling
skills. All equipment is provided by the
Fishing For Success Program.

Have You Seen This Plant?

Giant Salvinia (Salvinia molesta)

An Uninvited Guest

Yet another aggressive aquatic weed has appeared in the U.S. and is now cover-
ing significant areas of lakes and waterways in Texas and Louisiana.
Giant salvinia (Salvinia molesta),which is extremely similar to common Salvinia
(Salvinia minima), grows rapidly, spreading aggressively by buds that break off when .
disturbed. It forms floating mats that shade and crowd out important native plants.
Thick mats of this weed, reportedly able to float a cinder block, reduce oxygen con-
tent and degrade waterquality. The weed mats snag boats and clog water intakes for 1.
irrigation and electrical generation. Giant salvinia is most likely to be introduced with
aquarium or water garden plants. Efforts are underway to eliminate these infesta-
Any suspected sightings of the giant salvinia should be reported immediately to your state wildlife agency and also please
report it to the U.S. Geological Survey. Colette Jacono, a biologist with the USGS in Gainesville, is mapping new sightings in
Florida, and is also acting as a clearing house of identification and control information. In addition, informative printed material with
pictures are available for distribution.
Description: This plant has oblong floating leaves, 1/2to 11/2 inches, often folded and compressed into upright chains. It's larger
than common salvinia-which has nearly round leaves that lie flat on the water surface. Anotherway of distinguishing the two is that
giant salvinia (the exotic) has white bristles on the leafs surface. These bristles are joined at the tips and resemble tiny egg beaters.
You'll have to view the leaves with a hand lens to see this detail. The bristles have a velvety appearance and repel water.
To report sightings in Florida or for more information, call (877) 786-7267 or Colette Jacono at
352/378-8181 ext 315. Or you can view the web site at: http://nas.er.usgs.gov/ferns

As reported in previous issues of
WaterWorks, the aquaculture regulatory
process has been undergoing changes. The
merging of several state regulatory agen-
cies into the new Division of Aquaculture,
within Florida's Department of
Agriculture and Consumer
Services (FDACS) should
certainly speed things up. In --
the news:
Four state-wide Technical
Advisory Committee meetings
were held before formally pub-
lishing the proposed new
Interim Rule, which will govern
the industry until more perma-
nent Best Management Prac-
tices (BMP's) can be finalized.
The Interim Rule, which
could be adopted as early as
Oct. 1 in 1999, establishes
and implements aquaculture
interim measures, and con-
tinues to exempt minimal
impact facilities-which only have to
apply for an Aquaculture Certificate of
Registration from the FDACS in
accordance with the Interim Rule.
One item of particular importance is that
existing General Permit holders of these

operations are not required to renewtheir exist-
ing General Permit for Fish Farms, General Per-
mit for Bivalve Facilities, or their Chapter 370.26
permits as long as: (a) no major modifications
have been made to the facility; (b) the facility

is in compliance with applicable water resource
regulations; and, (c) the facility has submitted
a complete application with Notice of Intent
for Certification and all appropriate fees are
sent to FDACS.
The new rule also provides for two new

minimal impact aquaculture facilities: bivalve
raceways with less than 800 square feet of
raceways or down-wellers that do not add
supplemental algae as a food source, and
aquaculture production-recirculation
systems that do not discharge
to waters of the state.
The development of the
Aquaculture BMP Manual is
approximately 50 percent
complete. Most of the six
BMP industry specific sub-
committees have met several
times and have completed
working drafts.
A Peer Review Coordi-
nating Panel has also been
formed by FDACS to
ensure that BMP text is
consistent, technically accu-
rate, and that the final work
product is properly formatted.
The full Aquaculture
Technical Advisory Commit-
tee, comprised of industry and agency
personnel, may meet again later this year
to review all final draft BMPs prior to
continued rulemaking.
