SUMMARY ANALYSIS
The proliferation of a toxic or nuisance algae, known as a harmful algal bloom (HAB), produces toxic or harmful
effects on humans, fish, shellfish, marine mammals, and birds. One of the most commonly known HABs are
red tides, which have been documented in the Gulf of Mexico since the 1700s. Karenia brevis, the organism
that causes red tides, can result in the deaths of marine mammals, sea turtles, and sea birds and, for humans,
neurotoxic shellfish poisoning and respiratory impacts, particularly for those with asthma and other chronic
respiratory conditions.
The Florida Red Tide Mitigation and Technology Development Initiative (Initiative) was established by the
Legislature in 2019 to coordinate efforts amongst public and private entities to develop technologies to address
the serious negative impacts of red tide on Florida. The Initiative is a partnership between the Fish and Wildlife
Research Institute and Mote Marine Laboratory (Mote), and is set to expire on June 30, 2025.
The bill requires the Initiative to, upon successful completion of science-based laboratory testing of prevention,
control, and mitigation approaches and technologies (collectively “technologies”), develop recommendations
for field trial deployment in state waters of those technologies and submit a report on its findings and
recommendations to the Department of Environmental Protection (DEP), the Fish and Wildlife Conservation
Commission, the Department of Agriculture and Consumer Services, and other state agencies with regulatory
oversight of field trial deployment of the technologies in state waters.
The bill requires DEP to: evaluate the technologies and identify all existing state permits Mote may use to
deploy and test the technologies in state waters; submit its evaluation to Mote within 60 days after receipt of
the report; and, if DEP determines existing state permits may not be used, amend its regulatory or permitting
processes to ensure the timely deployment of any red tide or similar HAB technologies recommended by the
Initiative.
The bill requires, upon successful testing of the technologies, DEP to expedite regulatory reviews for the
recurring use of the technologies in state waters to control and mitigate the impacts of red tide or similar HABs.
The bill eliminates the expiration date of the Initiative.
The bill may have an indeterminate positive fiscal impact on local governments and the private sector. See
Section II., below.

 FULL ANALYSIS
I. SUBSTANTIVE ANALYSIS
A. EFFECT OF PROPOSED CHANGES:
Background
Florida boasts 825 miles of stunning coastline fronting the Atlantic Ocean, the Gulf of Mexico, and the
Straits of Florida.1 Beaches and the nearby waters are an integral part of Florida’s economy and
environment.2 Residents and tourists 3 alike visit the waters adjacent to beaches to engage in boating,
fishing, diving and other recreational activities.4 In addition, many Floridians depend on those waters
for their livelihoods, and Florida’s commercial and recreational fishing industries provide thousands of
jobs and billions of dollars in economic benefits. 5
Harmful Algal Blooms
Thousands of algae, simple photosynthetic organisms, live in marine and fresh waters. 6 These species
provide an important source of the oxygen we breathe and form the basis of the food web and while the
majority of them are harmless to humans and animals, “a growing number of species are being found
worldwide that produce toxins that can make humans sick and cause widespread ecological and
economic harm.”7 The proliferation of a toxic or nuisance algae, known as a harmful algal bloom
(HAB),8 produces toxic or harmful effects on humans, fish, shellfish, marine mammals, and birds 9 and,
consequently, the economy.
Red Tides
One of the most commonly known HABs are red tides, which have been documented in the southern
Gulf of Mexico since the 1700s 10 and along Florida’s Gulf coast since the 1840s,11 and even Spanish
explorers recorded fish kills near Tampa Bay.12 Red tides occur nearly every year in the Gulf of
Mexico,13 generally in late summer or early fall.14 Red tides develop offshore, are brought inshore by
winds and currents, and they may turn water color red to brown. 15 Karenia brevis (K. brevis), the
organism that causes red tides, “can result in:
 massive fish kills;
 the deaths of marine mammals, sea turtles, and sea birds; and
 for humans — neurotoxic shellfish poisoning and respiratory impacts, especially for those with
asthma and other chronic respiratory conditions.” 16

Florida’s brand are its beaches and, while the state has numerous appealing features, in terms of attracting tourists beaches have the
strongest effect. “It may be noted that, while beaches are the most attractive feature to visitors, they generally do not directly generate
revenue. Instead, they facilitate an array of expenditures that collectively comprise the cost of the tourism experience .”

 The “2018 Bloom”
The red tide bloom that began in October of 2017 and lasted until January of 2019 is also referred to as
the 2018 bloom.17 In 2018, then-Governor Scott issued executive orders declaring a state of
emergency in 14 counties associated with red tide blooms 18 and designated the Department of
Environmental Protection (DEP) the lead agency responsible for crisis management activities related to
the emergency.19
The negative effects from the 2018 bloom were numerous. It took several years for fish stocks to
rebound from Anna Maria Island near Tampa Bay south to Ten Thousand Islands,20 and it has been
estimated that there were approximately $184 million in losses in the tourism sector and the
consequent contraction in the Airbnb market corresponded to the loss of nearly 2,900 jobs throughout
Florida.21
A recently released study commissioned by the Conservancy of Southwest Florida, Sanibel-Captiva
Conservation Foundation, and Captains for Clean Water analyzed the impacts of poor water quality on
Southwest Florida.22 “The study found if what happened surrounding 2018 happens again in 2024 or
2025 it would result in the loss of $460 million in commercial and recreational fishing, more than 43,000
jobs, $5.2 billion in local economic output, $17.8 billion in property values, and the related loss of $60
million in property tax revenue.”23
The Florida Red Tide Mitigation and Technology Development Initiative
The Florida Red Tide Mitigation and Technology Development Initiative (Initiative) was established by
the Legislature in 201924 to coordinate efforts amongst public and private entities to develop
technologies to address the serious negative impacts of red tide on Florida. 25 The Initiative is a
partnership between the Fish and Wildlife Research Institute (FWRI) and Mote Marine Laboratory
(Mote).26
“The goal of the [I]nitiative is to develop, test, and implement innovative, effective, and environmentally
sustainable technologies and approaches for controlling and mitigating the impacts of red tide.”27 The
Initiative is required to submit an annual report to the Governor, the President of the Senate, the
Speaker of the House of Representatives, the Secretary of DEP, and the executive director of the Fish
and Wildlife Conservation Commission (FWC) that provides a synopsis of its accomplishments to date
and priorities for coming years.28
The Initiative expires on June 30, 2025.
FWC and the FWRI
The FWRI is the research division within FWC.29 FWC is empowered to exercise a number of the
regulatory and executive powers of the state, including those powers related to marine life. 30 “FWRI . . .
employs more than 600 people who work at its St. Petersburg headquarters and more than 20 field

 laboratories and offices situated at key inland and coastal locations statewide.”31 The FWRI provides
research and technical knowledge to a wide array of entities including governments, universities,
commercial and recreational fishing interests, and nongovernmental organizations. 32 The FWRI
employs a number of strategies to advance its mission, including identifying, monitoring, and providing
technical support related to red tides and other HABs.33 FWC is authorized to provide grants and
contracts to Mote to conduct research.34
Mote
Mote is a non-profit, independent research institution35 which is funded by foundations, individual
donors, and federal, state and local grants.36 For nearly 70 years Mote has conducted cutting-edge
marine research37 and it has decades of experience with red tide science. 38 What began as a one-room
building on Florida’s west coast39 is today a global leader in marine research, with nearly 300 staff
members,40 and scientists who conduct research on all seven continents.41
In 2018, Mote established the Red Tide Institute with a mission to “reduc[e] adverse impacts of Florida
red tide on public health, coastal marine ecosystems and Florida’s economy via the rigorous testing
and application of a ‘tool box’ of science-based mitigation and control technologies and strategies.” To
further its research of red tide, Mote created “a cutting-edge red tide mitigation testing facility . . . [that]
uses over 150,000 gallons of treated and recirculated seawater” for research, “along with ample lab
space for water quality, marine species, and toxin testing.”42 Funding of the Initiative has allowed Mote
to continue to expand vital testing of products to find those that kill the algae and minimize the impact of
the K. brevis toxin.43
Mote operates under the principle that mitigation or control strategies must do no further harm than that
already inflicted by red tide.44 As of January of this year, Initiative funding has allowed Mote to examine
more than 300 chemicals and compounds and many of the funded projects are ready for field testing.” 45
Effect of the Bill
The bill requires the Initiative to, upon successful completion of science-based laboratory testing of
prevention, control, and mitigation approaches and technologies (collectively “technologies”) develop
recommendations for field trial deployment of the technologies in state waters and submit a report on its
findings and recommendations to DEP, the Fish and Wildlife Conservation Commission, the
Department of Agriculture and Consumer Services, and other state agencies with regulatory oversight
of field trial deployment of the technologies in state waters.
The bill requires DEP to:
 Evaluate the technologies and identify all existing state permits Mote may use to deploy and test
the technologies in state waters;
 Submit its evaluation to Mote within 60 days after receipt of the report; and

B. SECTION DIRECTORY:
Section 1. Amends provisions in s. 379.2273, F.S., relating to the Florida Red Tide Mitigation and
Technology Development Initiative.
Section 2. Provides an effective date of July 1, 2024.
II. FISCAL ANALYSIS & ECONOMIC IMPACT STATEMENT
A. FISCAL IMPACT ON STATE GOVERNMENT:
1. Revenues:
None.
2. Expenditures:
None.
B. FISCAL IMPACT ON LOCAL GOVERNMENTS:
1. Revenues:
Red tide negatively impacts Florida’s economy by decreasing property values and tax revenues
collected by local governments. If the Initiative creates technologies or approaches that prevent or
mitigate red tide and its impacts, it may reduce the negative impacts to tax revenues collected by
local governments. Therefore, this bill may have an indeterminate positive fiscal impact on local
governmen
