The Effects of Regulations on the Florida Ornamental Aquaculture Industry, an Infographic

FA258/FA258by By Noah C. Boldt, Jonathan van Senten, Carole R. Engle, Eric J. Cassiano, and Matthew A. DiMaggioMay 31st, 2023This infographic accompanies "The Effects of Regulation on Ornamental Aquaculture Farms in Florida" (, an Ask IFAS factsheet that discusses the results of a study conducted to measure the impact of regulations on ornamental aquaculture farms in Florida using on-farm data from 2018. Florida’s diverse ornamental aquaculture industry has many unique challenges that set it apart from other aquaculture commodity groups. The numerous production techniques, diversity of species, and various market outlets make the ornamental aquaculture industry an intriguing study in how regulations impact the industry. By understanding regulatory impacts, we can streamline efforts to address them.Critical Issue: Agricultural and Food Systems

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

FA257/FA257by Edward Camp, Micheal S. Allen, Thomas T. Ankersen, Savanna Barry, and Mark W. ClarkApril 2nd, 2023Recreational 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.Critical Issue: Natural Resources and Environment

Florida Marine Baitfish Aquaculture Series – Part 1: Marketing Opportunities and Challenges

FA256/FA256by Marissa Drake, Andrew Ropicki, Matthew A. DiMaggio, Kelly Grogan, Cortney L. Ohs, Laura Tiu, Edward V. Camp, and Jordan MoorMarch 30th, 2023This publication, Part 1 in the Florida Marine Baitfish Aquaculture series, outlines opportunities and challenges associated with marketing aquacultured live marine baitfish in Florida. It examines why Florida is uniquely suited for the continued development of this industry, reviews the marine recreational angling baitfish market, and describes the opportunities and challenges associated with marine baitfish marketing and selling live baitfish to marine baitfish retailers. This publication is intended to provide information to current and potential farmers, as well as management agency and outreach personnel and the interested public. It should help farmers, potential farmers, and perhaps investors understand the potential scale, opportunities, and challenges of live baitfish aquaculture in Florida. This same information can assist policymakers and outreach personnel in their management decisions and the communications of those decisions.Critical Issue: Agricultural and Food Systems

Determination of Microalgal Concentration by Use of Turbidity Measurement

FR466/FOR395by Huiping Yang and Jayme C. YeeMarch 27th, 2023The goal of this study was to develop a rapid assessment of microalgal concentration using a turbidity meter to serve commercial shellfish hatcheries for feeding shellfish larvae and broodstock. We used four commonly used algal species, Tetraselmis suecica, Isochrysis galbana, Chaetoceros calcitrans, and Chaetoceros gracilis, generating serial dilutions of each and measuring cell concentrations and turbidity of each sample. We identified linear correlations between cell concentration and turbidity and established standard equations between cell concentration and turbidity for each species. We sampled and quantified algae from a shellfish hatchery using these equations and compared hemocytometer counts. No differences were found (P = 0.174), indicating the accuracy of the equations. We expect that this method can provide a quick, accurate, easy method for shellfish hatcheries to quantify algal concentration and avoid either over- or underfeeding larvae and broodstock. Critical Issue: Agricultural and Food Systems

Coastal Armoring Impacts on Beaches and Sea Turtles

FA255/FA255by Melissa Hill, Ray Carthy, and Martha MonroeMarch 16th, 2023Close to 19.6 million people live in Florida, and 76.5% of them, or approximately 15 million, live on the coast. Florida’s coasts are attractive despite the increasing risks from sea-level rise and more frequent climatic events such as hurricanes and coastal flooding. At particular risk from these erosive events are Florida’s 825 miles of sandy beaches. Coastal armoring is a physical barrier placed with the intent of protecting structures from storm, surf, and erosion damage. This publication explains how coastal armoring works and the impacts it has on nearby beaches and sea turtle habitat.Critical Issue: Natural Resources and Environment
