Programs in Aquaculture, Aquatic Animal Health, Conservation and Management of Natural Environments, and Sustainable Fisheries.
FISHERIES & AQUATIC SCIENCES (FAS) PROGRAM
Fisheries and Aquatic Sciences provides objective science to support the protection and management of fisheries and aquatic resources, with innovation and excellence in research, education and extension. Faculty have programs in four areas: Aquaculture, Aquatic Animal Health, Conservation and Management of Natural Environments, and Sustainable Fisheries. Many projects span these areas and involve collaboration with other scientists at UF, other universities and institutes, and state & federal resource management agencies.

FAS PROGRAM NEWS
AREAS OF STUDY
The sustainable fisheries program serves Florida’s recreational and commercial fisheries, which have the highest economic value of any state in the USA. The program focuses on 1) the effects of habitat quality on fish populations, 2) population modeling and stock assessment, 3) identifying essential fish habitat, and 4) public outreach for sustainable fisheries. Research areas of this program include both marine and freshwater fisheries and encompass population biology and modeling, behavioral ecology, life histories, and factors influencing fish community structure. Specific studies have estimated growth and mortality of commercial and recreationally important species, predicted population responses to changes in size limits, identified impacts of tournament angling on recreational fisheries, tested habitat effects on variation in growth and life history parameters, and assessed population biology and community dynamics of warm-temperate reefs.
AQUATIC ANIMAL HEALTH
Aquatic animal health is a truly interdisciplinary program well established at the University of Florida that involves faculty, staff and students from Fisheries and Aquatic Sciences, The College of Veterinary Medicine, and The Whitney Laboratory. This program focuses on, 1) disease diagnosis & health management, 2) assessment of the effects of toxic algal blooms & environment contaminants, and 3) an intensive educational program in aquatic animal health through the Graduate School and Extension Programs. For more information on this core area: Aquatic Animal Health.
Aquaculture is the cultivation of freshwater or marine organisms, including fish, shellfish, and plants. On a worldwide scale, as well as in our own backyards, aquaculture plays many important roles in agriculture and natural resource management. Aquaculture is used to 1) produce economically important animals and plants for food, recreation, commercial products and ecosystem management, 2) protect and enhance wild populations through captive breeding and artificial rearing, and 3) maintain organisms under controlled conditions in order to study fundamental biological processes. In order to successfully culture aquatic organisms in managed systems, aquaculturists must take advantage of a variety of biological disciplines including nutrition, growth, reproduction, medicine, husbandry and engineering. Our department emphasizes genetics, reproductive and environmental physiology, health management, and nutrition. Tropical Aquaculture Laboratory
CONSERVATION AND MANAGEMENT OF AQUATIC ENVIRONMENTS
Conservation and management of aquatic environments is a response to the serious challenges facing Florida due to the explosive growth of human development. This program focuses on 1) achieving an objective and comprehensive understanding of the structure and function of ecosystems, 2) providing critical information needed for the development of management approaches that ensure the integrity and sustainability of critical natural resources and 3) generating the human resources needed to meet the management challenges of the future through education and extension programs.
Fish Stock Assessment – involves accurately estimating abundance, growth, age and size structure in order to maintain sustainable fisheries. Citizens are concerned because these assessments are used to set limits on commercial and recreational harvest. We provide objective science to agencies that assess stocks. Predictive modeling is the key growth area for this program.
Fisheries Habitat Enhancement – relates to effects of mechanical habitat alteration in lakes and hydrologic restoration in rivers. Citizens are concerned about loss of fish habitat related to stabilized lake levels and shoreline development. We provide science to agencies in support of habitat remediation in fresh waters.
Artificial Reefs – relates to research conducted over the last ten years by this Department to optimize size and configuration of artificial reefs as valuable fisheries habitat in the Gulf of Mexico. Citizens are concerned about intense fishing pressure on natural reefs and recognize the benefits of artificial reefs for sustainable fisheries, recreational diving, and other activities. We provide the science and outreach in support of state-wide development of this program.
Toxic Algal Blooms – relates to impacts of blooms in freshwater and marine systems. Citizens are concerned about beach closures and fish kills due to red tides along the Gulf Coast and warnings about swimming, fishing and contact recreation in lakes and rivers. We are working with the College of Veterinary Medicine (CVM) to develop a comprehensive program to identify controls of algal blooms, levels of toxin production, and effects on fish and other aquatic biota.
Eutrophication – relates to effects of increased nutrient inputs to lakes, springs, rivers and coastal waters, and to standards set by the USEPA and Florida Department of Environmental Protection (FDEP) to limit nutrient inputs to aquatic resources. Citizens are concerned about high costs and potential negative outcomes if nutrients are not controlled effectively. Agriculture is concerned that discharges will be subject to overly restrictive limits. We provide objective science used to set standards that are appropriate for certain water bodies, considering their historical conditions and designated uses.
Exotic Species – number in the hundreds in Florida’s aquatic ecosystems, and include fish, invertebrates and plants. Many citizens are concerned about potential effects on native fish, shellfish and other biota, and this is a focus area for future research in our Department. We also work closely with the Center for Aquatic and Invasive Plants to examine effects of Hydrilla and other exotic / nuisance plants on ecosystem function and fishery production.
Aquaculture – focuses on enhancing productivity of hard clam, sturgeon and ornamental fish aquaculture. Citizens who keep aquaria or raise, sell or eat farm-raised seafood reap the benefits of our research, which has helped farmers produce high quality, economically viable products. Two growth areas are: developing new products that interface with traditional agricultural operations to increase revenue and address non-point source runoff issues related to nutrient standards.
Fish Kills and Aquatic Animal Health – focuses on effects of natural and anthropogenic pathogens and toxins on wild and cultured fish. Citizens who live near water or recreate on water are keenly aware that something is wrong when they see dead fish and/or fish with lesions. This Department, in concert with the CVM, examines how toxins and pathogens affect fish in natural systems and in the aquaculture industry, and identifies solutions to reduce risk of those impacts.
Ecosystem Restoration – relates to large-scale restoration projects occurring across the state. Citizens are concerned about impacts of altered water flow and other stresses are they are aware that billions of taxpayer dollars are funding these projects. We provide objective science to WMDs and other agencies conducting ecosystem restoration, and they use this information to design effective restoration project.
The state of Florida is renowned for its fishery and aquatic resources. More than 1,300 linear miles of coastline, 12 major bays and estuaries, 7,800 – plus lakes, 100,000 ponds, and thousands of miles of navigable rivers provide residents and visitors with a lifestyle rich in aquatic recreational and commercial opportunities. In addition to the sheer quantity of water, Florida spans nearly seven degrees in latitude, encompassing both temperate and subtropical marine and freshwater ecosystems.
However, rapid population growth continues to place increasing demands on the Florida’s aquatic resources. Conserving marine and freshwater resources, enhancing food and agricultural production, and meeting the water demands of all the state is inhabitants, will depend upon prudent and far-sighted management.
Recognizing the need for information and expertise in fisheries and aquatic sciences, the Department was established in 1984 by a core group of faculty from the School of Forest, Fisheries, and Geomatics Sciences (Drs. Jerome Shireman, Daniel Canfield, Jr., Bill Haller, and Joseph Joyce).
Within several years, the fledgling program had expanded beyond the bounds of the School of Forest, Fisheries, and Geomatics Sciences, resulting in its own Degree awarding department within UF’s Institute of Food and Agricultural Sciences. At that point it was named the Department of Fisheries and Aquatic Sciences (FAS). Twenty-four years after its establishment, FAS has become one of the fastest growing departments for aquatic research and education in the country. With a highly diverse and accomplished faculty, it is able to offer students a rich academic foundation.
As of July 1, 2008 Fisheries and Aquatic Sciences merged with the School of Forest, Fisheries, and Geomatics Sciences (FFGS) and is now one of three broad programmatic areas within the FFGS along with Geomatics and Forest Resources and Conservation.
Core facilities have also expanded from one small building to a large complex including offices, classrooms, numerous laboratories, and a hatchery facility located in Gainesville, as well as satellite research/teaching facilities in Ruskin.
