The History of Offshore Aquaculture Governance in the Gulf of Mexico

Aquaculture is a growing industry in Florida, and there is particular interest in offshore marine aquaculture. While inland and coastal aquaculture (like for shellfish or ornamental fish) is managed by the Florida state agency Florida Department of Agriculture and Consumer Services (FDACS), offshore aquaculture also involves federal management agencies. However, there has been some confusion and disagreement about which federal agencies will manage and make decisions about offshore aquaculture in the United States. This document describes a recent history and current state of that discussion. This information is important for potential aquaculturists and other stakeholders to understand, and should also provide guidance to management and outreach agencies seeking to inform stakeholders about offshore aquaculture.

Oysters are one of the most important natural resources found in coastal and estuarine areas of Florida, but some Florida oyster populations appear to be declining. One possible driver of oyster population decline is increased mortality from oyster predators, including marine snails. But other environmental factors, such as changes in temperature or salinity, may also affect oysters. This 5-page fact sheet written by Gabrielle Love, Shirley Baker, and Edward V. Camp and published by the UF/IFAS School of Forest Resources and Conservation, Program in Fisheries and Aquatic Sciences describes how a changing climate may affect oysters directly but also indirectly by affecting their predators.

Submerged aquatic vegetation has numerous benefits for aquatic ecosystems, from improving water quality to providing important habitat that supports a diverse food web. This new 6-page publication of the UF/IFAS Department of Soil and Water Sciences describes the breadth of options available to managers who wish to plant SAV at new locations. Because all methods have both benefits and drawbacks, and because all planting locations have different (often unknown) challenges for plant survival, managers may choose to try multiple methods to increase the likelihood for success.

Aquaculture applications of the Family Blenniidae

Close-up of a Smith's blenny.

Marine ornamental fish production is still in its infancy compared with its freshwater counterpart. About 1,800 wild-caught fish species are imported into the United States each year, clear proof of the need for the expansion of marine ornamental production to include new species and families of fish. Distinct behavior and a wide range of colors makes fish from the Blenniidae family, called blennies, a popular choice in the aquarium hobby. These hardy fish are small and rarely aggressive to other reef species and they eat algae and clean tank substrate. This 6-page fact sheet written by Jesse Von Linden, Joshua T. Patterson, Cortney L. Ohs, and Matthew A. DiMaggio and published by the UF/IFAS Program in Fisheries and Aquatic Sciences, School of Forest Resources and Conservation provides a brief overview of the family including description and taxonomy, natural history, culture techniques, a bit about disease challenges, and advice on marketing for ornamental Blennids.

Marine ornamental fish production is still in its infancy compared with its freshwater counterpart. About 1,800 wild-caught fish species are imported into the United States each year, clear proof of the need for the expansion of marine ornamental production to include new species and families of fish. The family Gobiidae is the fourth most imported family of marine ornamental fish. Gobies can be easily housed with a variety of other species of fish. Several have qualities that lend themselves to aquarium life. Some clean other fish and others sift the sand bed. Many naturally perch on the rockscape or corals, spending their time beautifying their surroundings with their bright colors and intriguing behavior. This 7-page fact sheet written by Jesse Von Linden, Joshua T. Patterson, Cortney L. Ohs, and Matthew A. DiMaggio and published by the UF/IFAS Program in Fisheries and Aquatic Sciences, School of Forest Resources and Conservation provides a brief overview of the family including description and taxonomy, natural history, culture techniques, a bit about disease challenges, and advice on marketing for ornamental Gobids.

The production of freshwater ornamental fish dominates the ornamental aquaculture industry, yet the small marine ornamentals sector has grown substantially in recent years. This 7-page fact sheet written by Elizabeth M. Groover, Matthew A. DiMaggio, and Eric J. Cassiano and published by the UF/IFAS Program in Fisheries and Aquatic Sciences, School of Forest Resources and Conservation briefly reviews the more common groups of marine ornamental fishes cultured in the United States. As we learn more about marine ornamentals and as aquaculture protocols for marine ornamentals develop and improve, it is possible that more species may become economically feasible to produce and more cultured marine fish may begin to supplement wild-caught stocks in the marine aquarium trade.

Triploid-tetraploid breeding technology has been applied to commercial oyster aquaculture worldwide. Triploid oysters are becoming the preferred aquaculture product because of their fast growth, better meat quality, and year-round harvest. Tetraploids are essential for triploid oyster aquaculture because commercial production of all-triploid seed depends on the availability of tetraploids for reproductive materials. This 8-page fact sheet written by Huiping Yang, Ximing Guo, and John Scarpa and published by the UF/IFAS School of Forest Resources and Conservation, Program in Fisheries and Aquatic Sciences, conveys basic knowledge about tetraploid induction and breeding to commercial shellfish culturists and the general public.

Microworm Culture for Use in Freshwater Ornamental Aquaculture

Microscopic image of adult microworms on a 1 mm grid. Under the microscope, their white, unsegmented, elongated bodies can be easily seen in constant motion.
A small nematode worm commonly referred to as a “microworm” has been a staple live feed used in the ornamental aquaculture industry for over 50 years. These worms are small enough to be ingested by the larvae of many commonly cultured ornamental species, and their production methods are simple and reliable. Microworms have the potential to provide appropriate nutrition in a live feed organism that is cultured entirely in-house and involves less labor and cost than newly hatched Artemia. In this 4-page fact sheet published by the UF/IFAS School of Forest Resources and Conservation, Program in Fisheries and Aquatic Sciences, authors Shane W. Ramee, Taylor N. Lipscomb, and Matthew A. DiMaggio discuss the biology, environmental requirements, and culture techniques for microworms and explain their importance for the larval culture of freshwater fish species.

Tilapia Lake Virus (TiLV): a Globally Emerging Threat to Tilapia Aquaculture

Tilapia lake virus is a globally emerging virus responsible for episodes of mass mortality in cultured and/or feral tilapia (Oreochromis spp. and hybrids) in Asia, Africa, Central America, and South America. Since 2014, there have been global reports of TiLV disease resulting in 10% to 90% mortality in tilapia fry, juveniles, and adults causing significant economic losses. Currently, the disease has been confirmed in Colombia, Ecuador, Egypt, India, Indonesia, Israel, Malaysia, Mexico, Philippines, Peru, Tanzania, and Thailand. TiLV has not yet been found in the USA or Canada, but it has most recently been reported in 20 aquaculture production facilities across six Mexican states (Chiapas, Jalisco, Michoacán, Sinaloa, Tabasco and Veracruz). This 7-page fact sheet written by Lowia Al-Hussinee, Kuttichantran Subramaniam, Win Surachetpong, Vsevolod Popov, Kathleen Hartman, Katharine Starzel, Roy Yanong, Craig Watson, Hugh Ferguson, Salvatore Frasca Jr., and Thomas Waltzek and published by the UF/IFAS School of Forest Resources and Conservation, Program in Fisheries and Aquatic Sciences describes this important emerging disease and explains how to prevent outbreaks and what to do if you suspect TiLV in an aquaculture facility or in the wild.

Preventing Escape of Non-Native Species from Aquaculture Facilities in Florida, Part 4: Operational Strategies

A screened basket on the intake hose prevents escape

Structural strategies to prevent the escape of non-native species from aquaculture facilities have numerous environmental benefits, and research at the UF/IFAS Tropical Aquaculture Laboratory has shown that structural strategies also reduce non-compliance with Florida Department of Agriculture and Consumer Services Best Management Practices. Operational and management strategies, however, are also very important. The strategies discussed in this 6-page fact sheet, the management of water, facilities, and employees, must not be overlooked. Operational strategies are easy, inexpensive, and, when used alongside structural strategies, highly effective, offering an impressive return on a minimal investment in the overall effort to minimize the escape of non-native species.

Written by Quenton M. Tuckett, Carlos V. Martinez, Jared L. Ritch, Katelyn M. Lawson, and Jeffrey E. Hill and published by the School of Forest Resources and Conservation, Program in Fisheries and Aquatic Sciences, this fact sheet is the fourth in a four-part series devoted to educating industry and other stakeholders on the importance of preventing escape of non-native species from aquaculture facilities as well as strategies for non-native species containment and regulatory compliance.
