Each fish is approximately

an average of 1.5 pounds.
Each fish yields one pound

ers working on Lake Apopka's
Until recently, the market for
the fish was restricted to use
as bait. However, recent work
conducted by the Florida
Department of Agriculture's
Bureau of Seafood Marketing
& Aquaculture has proven the
potential of marketing this fish
for human consumption. Their
work has resulted in the devel-
opment of consumer products
from the fish roe (eggs), gizzards
and processed fish meat.
Gourmets see the fish's roe and
gizzards as delicacies. While it's not
known if Americans will eat the fish
as it's prepared by gourmets around
the world, taste tests have research-
ers hopeful that Florida shad will
become an export product.
"It's a tasty fish with a great deal
of potential," says Seafood Market-
ing's Charlie Thomas. "We've devel-
oped a number of tasty recipes and
we're excited about a consumer
market for this product.

District researchers estimate a
consumer market for Florida shad
would have an annual economic
impact approaching $1 million.
Each of the ten fishermen with
permits to fish for shad are catching
more than 4,000 pounds of shad
per day. Roe and gizzards are
being exported, providing income
to fishermen and fish processors.
Local businesses benefit from
fishermen patronizing hotels, rest-
aurants and stores, purchases of
ice to preserve the fish, and fuel
purchased for the fishing boats and
trucks. Additional jobs are created
for loading, transporting and pro-
cessing the fish.
Jim Conner, Lake Apopka Inter-
agency program manager, says it's
a win-win situation.
'The local economy gets a boost
because private fishermen harvest
the fish, additional jobs could be
created and it's an abundant food
source that tastes good," says Con-
ner. "It's a great example of a pub-
lic-private partnership. And best of
all, it's a restoration technique that
could pay for itself...with the end re-
suit being a cleaner Lake Apopka."

SWIM stands for the Surface
Water Improvement and Manage-
ment Act passed by the Florida
Legislature in 1987. It provides for
the cleanup, restoration and
protection of Florida's lakes, rivers,
bays and other waterways.
In passing the SWIM bill, the
Legislature noted that pollution has
jeopardized some functions of many
of Florida's important water bodies,
such as Lake Apopka.
Through the SWIM Act, the
Legislature directed the state's five
water management districts to
develop priority lists of water bodies

needing attention. Annual appropria-
tions to the SWIM Trust Fund have
provided the majority of monies
needed to begin addressing these
pollution problems.
The St. Johns River Water
Management District has initiated
work in four SWIM program areas
with great success. They are: Lake
Apopka, the upper Ocklawaha River,
the lower St. Johns River, and the
Indian River Lagoon.
Unfortunately, reductions in state
funding have caused the elimination
