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.

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.

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.

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.

What is stock assessment?

Nicholas Fisch, Angela Collins, and Edward V. Camp

Whether you’re an angler, diver, conservationist, or just interested in fisheries, you’ve likely heard the term “stock assessment” before. What are stock assessments? How do they work? How do they inform management decisions? This publication provides information to the public and people serving in natural resource management agencies and working in outreach and Extension to show how fisheries management decisions are made.

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.

Artificial Reefs in Florida 101: Effects on Fishers (and Divers)—Part 3 of an Artificial Reef Series

Lisa Chong, Angela B. Collins, Holly Abeels, Anna Braswell, Ana Zangroniz, Andrew Ropicki, Scott Jackson, 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 3 of the Artificial Reefs series, explains how artificial reefs affect fishers and divers. It will help the interested public understand more about the ecological effects of artificial reefs and provide detailed information to stakeholders including management agencies, local governments, artificial reef manufacturers, and Extension agents, to allow for better-informed decisions about building and managing artificial reefs.

Artificial Reefs in Florida 101 – why are they built? Part 1 of an Artificial Reef series

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 1 of the Artificial Reefs 101 series, explains why artificial reefs are built. It defines what artificial reefs are and explains why people build and deploy artificial reefs. It should help the interested public understand how artificial reefs affect marine resources, and provide a background and baseline of information for decision-makers such as local officials, management agency personnel, and Extension agents.

Fish Population Recruitment: What Recruitment Means and Why It Matters

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.

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.
