An Update on Florida’s Artificial Reefs: Recent Research and What It Means for Florida

Edward V. Camp, Lisa Chong, Angela B. Collins, Holly Abeels, Keith Mille, Michael Sipos, Brittany Hall-Scharf, Ana Zangroniz, Scott Jackson, Shelly Krueger, and Victor Blanco

As coastal managers and practitioners continue placing artificial reefs in marine waters, the scientific understanding of the effects and implications of artificial reefs is changing. It is especially important for resource managers and Extension and outreach personnel, as well as the interested public, to keep aware of these changes as they occur, but usually scientific studies are first published in peer-reviewed journals that may be inaccessible. This publication describes some of the most recent artificial reef studies that are likely to be especially relevant to Florida. Each is summarized and its potential relevance to Florida described. This is not a complete record of recent research, but it should help the interested public, managers, educators, and outreach personnel stay informed of recent developments in artificial reef science that should be considered when making decisions about artificial reefs.

Artificial Reefs in Florida 101 – effects on fisheries: Part 4 of an Artificial Reef series

Lisa Chong, Angela B. Collins, Holly Abeels, Anna Braswell, Andrew Ropicki, and Edward V. Camp

Increasingly, coastal managers are placing artificial reefs in marine waters. These long-lasting habitat alterations have measurable effects on fish, fishers, divers, fisheries, and marine social ecological systems. Understanding how artificial reefs function is necessary to make good decisions about future artificial reefs. Scientific research on many aspects of artificial reefs is not always summarized and explained. In response to this need, we designed a 4-part series called Artificial Reefs 101. This publication, part 4 of the Artificial Reefs series, explores a complicated but fascinating aspect of artificial reefs—should we expect them to lead to better fishing in the long run? Many people think artificial reefs should be a “win-win” since both fish and fishers seem to like them. But it is increasingly apparent that they are likely to increase fishing mortality more than they increase fish populations. So they could lead to more restrictive regulations.

Candidate Species for Florida Aquaculture: Almaco Jack, Seriola rivoliana

Victor Blanco, Cortney Ohs, Nicole Rhody, and Ronald Hans

Almaco jack, Seriola rivoliana, is a perciform within the order Perciformes, family Carangidae; which includes jacks and pompanos. They are members of the genus Seriola, a species of interest for aquaculture diversification worldwide. Like other commercially farmed Seriola species, almaco jack (also known as longfin yellowtail and kampachi) are fast growers, have a high market value, and are increasingly well-regarded among chefs for their versatility in both cooked and raw preparations. These characteristics, among others, have made them favorable candidates for both land-based and offshore aquaculture.

Diffusion of Innovation Explaining Support for Septic to Sewer System Conversion Programs Among Florida Residents: Lessons for Educators and Related Stakeholders

Dharmendra Kalauni, Laura Warner, Lisa Krimsky, Shelli Rampold, and Sravani Pasula

Water quality impaired by excess nutrients has been linked to negative effects on human health, the environment, and the economy. Residential septic systems (i.e., onsite sewage treatment) contribute to these excess nutrients. Conversion from a septic system to a sewer system (hereafter referred to as S2S) is one way to mitigate pollution from excess nutrients. There are voluntary and mandatory S2S conversion programs throughout and beyond Florida. While there are multiple benefits of making such a change, S2S conversion is a complex and costly process. This document was developed to aid environmental management professionals, policymakers, and communication and education professionals (e.g., Extension agents) in understanding residents’ perceptions pertaining to S2S conversion. More details on the study presented in this document are available at: https://doi.org/10.1016/j.jenvman.2022.115651.

Living Shoreline Ecosystem Service Valuation Tool

Ashley R. Smyth, Laura K. Reynolds, Savanna C. Barry, Natalie C. Stephens, Joshua T. Patterson, and Edward V. Camp

Living shorelines are an increasingly popular way to protect and stabilize waterfronts for coastal property owners. Living shorelines provide valuable benefits to humans, including water quality improvement, habitat, fisheries, and carbon sequestration. Estimating the economic value of the ecosystem services living shorelines offer is an integral part of management decisions. The living shoreline valuation tool can help quantify the costs and benefits of living shorelines projects. This publication briefly describes the ecosystem services associated with living shorelines. The purpose of this publication is to introduce the ecosystem service valuation tool. Our target audience for the living shoreline evaluation tool includes natural resource extension agents, community organizations, and coastal homeowners who want to calculate the value of ecosystem services provided by coastal restoration projects, including living shorelines.

Recreational Fishing Effort and How Management Actions Can Affect It—Part 1: Theory

Edward Camp, Micheal S. Allen, Thomas T. Ankersen, Savanna Barry, and Mark W. Clark

Recreational fishing is especially important to Florida’s economy and ecosystems. One of the most important metrics of recreational fisheries is “effort”—defined as the number of trips taken during a time and place. Effort is so important because it directly affects fish population sustainability, economic value and market activity. But what determines fishing effort? This publication describes the mechanisms that drive fishing effort. It specifically details the processes by which management actions can directly and indirectly affect fishing effort, and how feedbacks between these actions can change effort. The information in this document is critical for people involved with management decisions, like agency personnel and their stakeholders; those wanting to explain it to others, like extension agents; directly affected stakeholders like recreational fishers and guides; or simply the general public who want to know more about recreational fisheries in Florida.

An Introduction to Harvest Tags for Marine Recreational Fisheries

Edward Camp, Zachary Siders, Andrew Ropicki, and Frank Asche

Managing recreational fisheries requires balancing sustainability against allowing as much access and harvest as possible. Maintaining sustainability is made harder by discard mortality where any fishing activity, even catch and release, risks fish dying from injuries, predation, or other causes. This is especially a problem for Florida reef fish species that live at depths and habitats where barotrauma increases mortality and depredation by larger fish, sharks, or marine mammals increases it further. Harvest (or trip) tags could reduce overharvest, lower discard mortality, and allow anglers more freedom to choose when to fish. Harvest tags would limit the total fish harvested, but could eliminate one of the least popular current management restrictions, harvest seasons. This publication describes harvest tag approaches, discussing how they are already used in fishing and hunting and describing some of the potential benefits and costs if they were applied in Florida.

Artificial Reefs and People: How We Create Them and How They Affect Us

Candidate Species for Florida Aquaculture: American Horseshoe Crab Limulus polyphemus

Lena Donnarumma, Brittany J. Scharf, Jeffrey E. Hill, and Cortney L. Ohs

The American horseshoe crab, Limulus polyphemus, is a member of the phylum Arthropoda, subphylum Chelicerata, and class Merostomata. Although there are four horseshoe crab species worldwide, the American horseshoe crab is primarily found in the Atlantic Ocean along the East Coast of North America. The species ranges from Maine to Mexico, but is absent between Texas in the United States and Tabasco in Mexico. They mainly inhabit estuarine areas; however, juveniles and adults can venture into the shallow oceanic environments. Embryo development occurs in the intertidal zone of sandy beaches. Sandy or muddy bottom habitats are necessary for burrowing and benthic feeding. This publication will cover their natural history, aquaculture techniques, common diseases, and their uses and markets.

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 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.

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.

Ocean Acidification: Effects on Sponges

Lena A. Donnarumma, Joseph Henry, Joshua Patterson, Shelly Krueger, Lisa Krimsky, and Shirley Baker

Approximately 30% of the carbon dioxide (CO2) released into the atmosphere has been absorbed by the world’s oceans. As CO2 emissions increase due to human activities so does the amount of CO2 absorbed by the oceans. Carbon dioxide lowers the pH of the ocean system, causing ocean acidification (OA). The effects of OA on economically and ecologically important aquatic species is a subject of interest. Sponges are important reef-associated species that provide shelter for fish and crustaceans in reef habitats and can also structure ecosystems through bioerosion, water filtration, and colonization of coral reef areas. This publication considers the effects of OA on marine sponges, with a focus on Florida’s coral reef.

Recreational Fishing Effort and How Management Actions Can Affect It—Part 2: Literature and a Case Study

Edward Camp, Micheal S. Allen, Thomas T. Ankersen, Savanna Barry, and Mark W. Clark

Recreational fishing, crucially important to Florida’s economy and ecosystems, can be affected by management decisions. Decisions that change the allowable harvest or the type of access to certain fishing areas are often expected to have strong effects on fishing effort, but the outcome of these actions is not always obvious. To provide greater insight into what may happen to fishing effort after management decisions, we describe case studies from the North American fisheries literature, some Florida-specific. These illustrate that the same or similar management actions (e.g., a more restrictive harvest policy) can have opposite effects on total fishing effort depending on the specifics of the case. We use this information as well as additional fisheries theory to explore a specific case study—what might happen if special harvest or access regulations were applied to a popular but ecologically and environmentally sensitive habitat—Florida's St. Martins Marsh Aquatic Preserve.

The Coral Holobiont: A Brief Overview of Corals and Their Microbiome

Monica D. Schul, Ashley R. Smyth, Joshua T. Patterson, Ana N. Zangroniz, Shelly L. Krueger, and Julie L. Meyer

Caribbean and tropical western Atlantic reefs have declined drastically since the 1970s. In some locales like the Florida Keys, the decline of branching corals approached 98%. These declines are widely attributed to recurring stressors such as high ocean temperatures and disease. The preservation and restoration of reefs is imperative as coral reefs support 25% of the world's known marine species and create billions of dollars in economic value. However, current restoration efforts have low success rates, so researchers are looking to better understand how stony corals respond to and overcome these stressors. Pioneering efforts to elucidate the role of the coral microbiome have shown that microbes are an important component for stony coral health, nutrition, and disease defense. This publication is for various natural resource professionals who want information on corals, microbiomes, and how coral microbial ecology research is pushing our knowledge of corals and restoration forward.

An update on Florida’s Artificial Reefs: recent deployments and trends

Edward V. Camp, Lisa Chong, Angela B. Collins, Holly Abeels, Keith Mille, Michael Sipos, Brittany Hall-Scharf, Ana Zangroniz, Scott Jackson, Shelly Krueger, and Victor Blanco

Popular marine habitat enhancements, artificial reefs can benefit sea life and humans. Floridians visit them every year to fish, dive, snorkel, or boat around. The number of artificial reefs is growing around Florida, but their function and impact are difficult to describe because artificial reefs change over time as they become encrusted with fouling organisms or altered by storms and shifting sands. As reefs change, expectations shift, and advances in research and monitoring allow us to learn more about them. This publication provides an update of Florida’s recent artificial reef activities. It focuses on new deployments, designs, and monitoring objectives from 2015 to 2021. It should help management agencies and outreach and education professionals understand recent trends in priorities. Fishing and diving clubs, monitoring programs, local artificial reef planners and coordinators, and other stakeholders can discover and share information learned across counties.

Ecological Influences on Coastal Finfish Recruitment

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

Florida is experiencing many human and climate-related changes to the aquatic environment that can affect fish. Lost or altered habitat, for instance, can lead to changes in fish populations that may impact survival, growth, or recruitment of those populations. Recruitment influences how many adult fish are later available for spawning and continuing the population. Understanding recruitment and how it is affected by ecological influences is important for considering the potential effects of ongoing climate change, as well as restoration and management of water quality and habitat. This publication provides background information useful to anyone interested in understanding more about factors affecting fish populations and should be especially useful to Extension agents and management agency personnel who would like an overview of these topics before engaging with stakeholders.

Fish Population Recruitment 2: Stock Recruit Relationships and Why They Matter for Stock Assessment

Edward V. Camp, Robert N.M. Ahrens, Angela B. Collins, and Kai Lorenzen

A good understanding of stock recruit relationships is essential for accurate stock assessment and good fisheries management. But the concept is complicated and can be difficult to understand. This publication uses a recent Florida spotted seatrout stock assessment as an example to show how the stock-recruit relationship allows managers to determine whether or not a given fish population is overfished.

Food Traceability Rule Overview: A Guide for Florida Food Industry

Sharon Xin Ying Chuah and Razieh Farzad

The FSMA's Traceability Rule, finalized in 2022, aims to establish a comprehensive system for tracking specific foods along the value chain from farm to fork, to prevent and respond to foodborne illnesses more effectively. The industry should implement the rule by 2026. This revision is part of the FDA's New Era of Smarter Food Safety blueprint and implements Section 204(d) of the FDA Food Safety Modernization Act (FSMA). The FDA's Final Traceability Rule initially focuses on specific food categories identified as higher risk for contamination and foodborne illnesses. These categories are referred to as the "Food Traceability List" (FTL). In this EDIS publication, we have provided to the food industry background information and an overview of the rule's key components and the foods covered by it. Additionally, available resources have been compiled in a table to help the industry understand the rule better and find more information about it.

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.

Let ‘Em Grow: Scalloping Best Practices

Brittany Hall-Scharf and Victor Blanco

Recreational scalloping is a popular summertime activity that attracts participants from far and wide to Florida's Gulf Coast. Coastal counties that serve as vessel launch points rely on this fishery for economic viability, but the biology of the bay scallop and the environmental stressors this species endures have led to limited populations of bay scallops remaining along Florida's Gulf Coast . Therefore, it is essential to implement best practices for harvesting bay scallops so that future generations can enjoy this marine resource activity. This publication gives recreational scallopers tips on how to sort through scallops in the water so that scallops that are too small are returned immediately to the same spot where they were taken. Improving harvesting techniques can help sustain this valuable fishery.

Los colibríes de Florida

Ocean Acidification: Fish Physiology and Behavior

Joshua Patterson, Lisa Krimsky, and Joseph Henry

This document is one in a series on ocean acidification (OA). The series Introduction, Ocean Acidification: An Introduction, contains information on the causes and chemistry of OA. Because OA is very large-scale and complex, each document in the series addresses a specific aspect of this issue. Florida, with an extensive coastline and deep cultural and economic ties to marine resources, will be directly affected by changes in seawater chemistry. Thus, each topic in the series also highlights information of specific relevance for Florida.

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.

Reconociendo las Serpientes Venenosas de Florida

Steve A. Johnson y Martin B. Main, y traducido por Alejandra Areingdale, Miguel Acevedo, y Armando Ubeda

En Florida habitan más de 50 especies de serpientes nativas, de las cuales sólo seis son venenosas. Las especies venenosas incluyen cinco víboras crotalinas (la serpiente oriental de cascabel de dorso de diamante, el crótalo de los cañaverales, el crótalo pigmeo, la cabeza cobriza, la boca de algodón) y la serpiente coral. Las cabezas cobrizas y las serpientes crótalo de los cañaverales tienen un rango de distribución limitado en Florida. Esto incluye una área pequeña al oeste de Tallahassee y algunos condados al Noroeste de la Florida para las cabezas cobrizas, y el norte de Florida cerca de la ciudad de Gainesville para las serpientes crótalo de los cañaverales. Las otras cuatro especies venenosas son comunes en todo el estado. Las serpientes venenosas de Florida viven en una variedad de hábitats naturales, que incluyen desde los humedales hasta los bosques secos.

Repensando el papel del nitrógeno y fósforo en la eutrofización de los ecosistemas acuáticos

H. Dail Laughinghouse IV, Ashley Smyth, Karl Havens y Thomas Frazer

Históricamente, las agencias ambientales han buscado mejorar la calidad del agua de los lagos y ríos de agua dulce mediante el manejo de un solo nutriente. El fósforo era el nutriente principal de preocupación en los sistemas de agua dulce y el nitrógeno estaba regulado en los sistemas costeros y estuarios. Investigaciones recientes indican que debemos reducir tanto el fósforo como el nitrógeno para revertir los síntomas de eutrofización en todos los sistemas acuáticos. This new 5-page publication of the UF/IFAS Department of Soil and Water Sciences, written by H. Dail Laughinghouse IV, Ashley Smyth, Karl Havens, and Thomas Frazer, is a translation of SGEF190/SG118, "Rethinking the Role of Nitrogen and Phosphorus in the Eutrophication of Aquatic Ecosystems."

Selenium and Mercury Toxicity: The Tale of Fish

Razieh Farzad and Jeanette Andrade

Not only is fish a good source of protein, but it also provides essential fatty acids such as omega-3, vitamins such as vitamin D, and minerals such as selenium. However, consumers are concerned about exposure to mercury through fish consumption. The degree of exposure to mercury depends on both the amount and the type of fish consumed. Additionally, recent studies have shown that Se can prevent mercury poisoning. To better understand the risk of mercury exposure through seafood consumption, understanding selenium-mercury interaction is useful. This new 4-page document is the first in a "Fish and Human Nutrition" series, which seeks to help consumers make a knowledge-based decision when choosing their seafood. Written by Razieh Farzad and Jeanette Andrade and published by the UF/IFAS Food Science and Human Nutrition Department.
