Production and Performance of Triploid Oysters for Aquaculture

Huiping Yang, Natalie Simon, and Leslie Sturmer

This publication is focused on basic aspects of triploid oyster aquaculture, including the general oyster aquaculture industry, the approaches for triploid induction, performance of triploids, and correlated ploidy determination to convey basic knowledge of triploid oyster aquaculture to the oyster industry and the general public.

Market Opportunities for Florida Farmed Oysters

Robert Botta, Taryn Garlock, Edward V. Camp, Andrew Ropicki, and Frank Asche

The oyster aquaculture industry has grown quickly in recent years. New farming techniques target specific attributes that increase oysters' value and allow them to be sold in the high-value, half-shell market. A lack of economic data makes it difficult for growers to determine which specific attributes increase oyster value, however. This publication summarizes findings from a recent study that examined restaurant menus to obtain economic data on raw, half-shell oysters. Major findings indicate that brand is an oyster attribute that provides value, and that marketing oysters with information on two or more attributes can also result in higher prices. Additionally, locally sourced oysters are often sold at cheaper prices, providing an opportunity for growers from outside regions to enter new markets. The findings will be useful to Florida oyster growers as attempts to expand Florida’s oyster aquaculture industry continue.

Climate Change: Effects on Salinity in Florida’s Estuaries and Responses of Oysters, Seagrass, and Other Animal and Plant Life

Ashley R. Smyth, H. Dail Laughinghouse, Laura K. Reynolds, Edward V. Camp, and Karl Havens

Florida’s economically important estuaries could be heavily impacted by sea-level rise and altered river flow, both caused by climate change. The resulting higher salinity, or saltiness of the water, could harm plants and animals, alter fish, and bird habitat, and reduce the capacity of estuaries to provide such important services as seafood production and the protection of shorelines from erosion. This publication contains information for stakeholders, students, scientists, and environmental agencies interested in understanding how changes in salinity impact Florida’s estuaries.

How Do Oysters Remove Nitrogen?

Heather Donnelly, Ashley Smyth, Shirley Baker, Laura Reynolds, and Angela Collins

Nitrogen is natural and necessary, yet nitrogen levels above natural levels can cause algal blooms and eutrophication of coastal systems. The purpose of this document is to describe how oysters and oyster reefs remove nitrogen. This new 7-page publication of the UF/IFAS Department of Soil, Water, and Ecosystem Sciences is intended for policymakers, environmental organizations, and coastal residents who want to know about oysters' role in improving water quality through nitrogen removal. Written by Heather Donnelly, Ashley Smyth, Shirley Baker, Laura Reynolds, and Angela Collins.

What Is Oyster Shell Recycling?

Ana Zangroniz, Marian Azeem-Angel, Katie Heiden, Heather Donnelly, and Ashley R. Smyth

This publication is intended to serve Natural Resources or Florida Sea Grant Extension agents, as well as local partners considering establishing a local oyster shell recycling program or local restaurants interested in learning more about oyster shell recycling, and shares lessons learned from starting a program in Miami-Dade County.

Ensuring Safe Oysters: Essential Handling, Preparing, and Cooking Practices

Razieh Sadat Mirmahdi, Samantha Dicker, Razieh Farzad, Andrew J. MacIntosh, Amarat Simonne, and Naim Montazeri

This EDIS publication provides insights for both oyster consumers and the restaurants that serve them, offering recommendations on techniques to maximize the safety of oysters through proper cooking.

How Oyster Reefs Can Affect Finfish Recruitment

Gabrielle Love, Anna Braswell, Angela B. Collins, and Edward Camp

Recruitment is a very important life stage for fish which has direct impacts on size of the whole fish population. During this phase, the mortality juvenile fish experience is affected by their density because of competition for the available resources. How much fish density affects mortality in recruitment is itself affected by many factors, but one of the most important is the structural habitat available to juvenile fish. Structurally complex habitats like oyster reefs are thought to have a particularly strong influence on the recruitment process of certain species. Here we describe the ways that habitat can alter recruitment success. We focus on how oyster reefs affect recruitment of fish in Florida and the particular issues related to management of this important habitat.

Current Aquaculture of the Eastern Oyster Crassostrea virginica and Its Potential for Innovative Technology in Florida

Emily Caffrey, Joshua Patterson, Ruth Francis-Floyd, and Roy P. E. Yanong

<p>This publication provides information on the status of oyster fisheries and aquaculture in Florida as well as general information about how oysters are grown in agricultural and restoration systems. It then introduces a series of technologies that have been developed in other US states and in other countries, strategies that may have utility in Florida. Finally, it covers some specifics of the permitting process as it relates to oyster aquaculture in Florida.</p>

Oyster Habitat Restoration and Shoreline Protection

Charles Wallace, Edward Camp, and Ashley Smyth

As the climate continues to change, coastal areas and the people that live there face increasing risks from erosion and wave damage. This is made worse by declines in natural oyster reefs, which would provide some natural protection. However, oysters can be restored for the specific purposes of protecting shorelines. The practicality and cost effectiveness of using oysters in this way is described in this publication, which is intended to be used by coastal property owners, as well as local governments that must make decisions about protecting shorelines in the face of a changing climate.
