In a novel approach, Hernando County has incorporated a new Strategic Marine Area Plan into its comprehensive plan. The plan will help sustain and improve the marine environment from the shoreline seaward to the state line, a distance of 9 nautical miles.
Partial migration of the nurse shark, Ginglymostoma cirratum, from the Dry Tortugas Islands

Partial Migration of the Nurse Shark, Ginglymostoma cirratum, from the Dry Tortugas Islands

Previous research has characterized nurse sharks as mainly sedentary sharks, meaning they do not migrate. However, with advanced sampling techniques, this study found that some nurse sharks in the Dry Tortguas do in fact participate in seasonal migrations.
Discarded deep-sea shark

Stress, Post-release Mortality, and Recovery of Commonly Discarded Deep-sea Sharks Caught on Longlines

Deep-sea shark bycatch is common in longline fisheries, yet post-release mortality rates are not currently incorporated into management initiatives. This study deployed enclosures at depth to estimate the post-release mortality rates of the Cuban dogfish and the gulper shark.
Wind Loads

Wind Loads on Residential Scale Rooftop Photovoltaic Panels

Rooftop solar panels are gaining popularity. Reliable and efficient racking systems are important to keep them from getting damaged in inclement weather. This study used the Wall of Wind Research Facility to determine how critical wind directions, roof type and panel tilt angle affected the resilience of the panels.
Gulf of Mexico

Generalized Additive Models for Predicting the Spatial Distribution of Billfishes and Tunas Across the Gulf of Mexico

In an effort to predict the spatial distributions of economically and ecologically important billfish and tuna species within the Gulf of Mexico, this study developed generalized additive models, which were fitted with data from NOAA's Pelagic Longline Observer Program.                        
Deepwater Horizon oil spill

Impacts of the Deepwater Horizon Oil Spill Evaluated Using an End-to-End Ecosystem Model

This study used an ecosystem model called Atlantis to simulate how the Deepwater Horizon oil spill impacted the recovery of various fisheries. The model was validated by comparing population trends and age structure before and after the oil spill using fisheries independent data.
Marine Policy

Angler Travel Distances: Implications for Spatial Approaches to Marine Recreational Fisheries Governance

Recreational fisheries are increasingly being managed as socioecological systems, which requires consideration of the spatial dynamics of fish as well as anglers. This study assessed angler travel in six popular marine recreational fisheries in Florida.
Barotrauma Mitigation

Understanding Resource-Conserving Behaviors Among Fishers: Barotrauma Mitigation and the Power of Subjective Norms in Florida's Reef Fisheries

This study used an online survey to see which factors motivate anglers' decisions to use alternative barotrauma mitigation measures such as venting and descending to improve discarded reef fish survival across recreational, charter and commercial fisheries in Florida.
Angler's Targeting Bedding Bass

Global Patterns in the Motivations and Behaviors of Tournament Anglers Targeting Bedding Bass

Black bass bed fishing, or angling for the fish as it defends its nest, has been a concern since it may negatively impact reproductive success. Previous research has only focused on male-directed targeting, which may not accurately reflect angler behaviors. This study surveyed tournament anglers and found female fish were identified as the preferential targets.
North American inland fishes and fisheries

Grand Challenges in the Management and Conservation of North American Inland Fishes and Fisheries

This study used a grand challenges approach to identify critical roadblocks in the management and long-term conservation of North American inland fish and fisheries. Seven grand challenges were identified.
Recovery of plankton

Recovery of Plankton from Hurricane Impacts in a Large Shallow Lake

Using data from a long-term sampling program, this study quantified the recovery of plankton in Lake Okeechobee from the impacts of hurricanes Frances and Jeanne in 2004 and Hurricane Wilma in 2005.
Effects of egg stocking

Effects of Egg Stocking Density on Egg Hatchability, Larval Quality and Water Quality for Pinfish, Lagodon rhomboides, and Pigfish, Orthopristis chrysoptera

Pinfish and pigfish are two relatively new cultured species commonly used as marine baitfish in the southeastern U.S. and currently have no defined protocols for egg incubation. This study determined efficient egg stocking densities during static and flow-through incubation that yielded higher quality larvae.

Evaluation of Nutritional and Environmental Variables During Early Larval Culture of Pigfish Orthopristis chrysoptera (Linnaeus)

Pigfish are a commonly used baitfish in the southeastern U.S., but there is still a lack of information regarding larval culture methods. This study conducted experiments to determine effective strategies to yield high larval survival and growth during early development.
Creating Healthy Communities to Overcome Oil Spill Disasters

Oil Spill Science in the Gulf of Mexico

Extension specialists with the Sea Grant oil spill science outreach program have produced new titles about oil spill science in the Gulf of Mexico.
Butterfly fish

Spawning, Embryology, and Larval Development of the Milletseed Butterflyfish Chaetodon miliaris in the Laboratory

As part of the Rising Tide Conservation effort to advance marine ornamental aquaculture, this study documented the spawning behavior of 35 milletseed butterfly fish that were transported from The Rainbow Reef exhibit in Hawaii to the UF Tropical Aquaculture Lab in Florida.
First feeding parameters

First Feeding Parameters of the Milletseed Butterflyfish Chaetodon miliaris

This study evaluated the first feeding performance of the milletseed butterflyfish using three experiments examining prey type, microalgal cell density and prey density.
Brood density and spawning

Effects of Brood Density and Spawning Substrate Type and Orientation on the Reproductive Output of Seminole Killifish in Tanks

The seminole killifish has emerged as a marine baitfish aquaculture candidate because of its acclimation to seawater, fast growth, and resilient larvae. This study identified preferred spawning substrate materials and orientations to evaluate effects of broodfish stocking density on reproductive output.
Marine recreational fisheries

Trade-offs Between Socioeconomic and Conservation Management Objectives in Stock Enhancement of Marine Recreational Fisheries

Management of recreational fisheries is characterized by both conservation and socioeconomic objectives. This study used an integrated bio-economic model to explore the tradeoffs between conservation of fisheries resources and their use for socioeconomic benefit.
Marine Fisheries

Using Fisheries Modeling to Assess Candidate Species for Marine Fisheries Enhancement

This study shows how fisheries modeling informed by stock assessments can be used to evaluate contributions of stocked fish to fisheries and how these contributions are influenced by life history and fishery attributes including regulatory policies and angler effort.
Marine angler characteristics

Marine Angler Characteristics and Attitudes Toward Stock Enhancement in Florida

Fisheries stock enhancement is a common management strategy that also involves substantial tradeoffs between fisheries management objectives. This study used an internet-based survey to assess attitudes toward fisheries stock enhancement and other management measures among marine inshore anglers in Florida.
Brown shrimp

A Framework for Exploring How Density Dependence Early in the Life History Can Affect Louisiana's Brown Shrimp Fishery

The dynamics underlying fisheries stock–recruitment relationships are often obscure, especially with relatively short-lived invertebrate species, such as the brown shrimp Farfantepenaeus aztecus. This study developed a matrix model to link early shrimp life history with the fishable stock.
Small abolone Haliotis diversicolor

The Characterization of RHEB Gene and Its Responses to Hypoxia and Thermal Stresses in the Small Abalone Haliotis diversicolor

RHEB (Ras Homolog Enriched in Brain) is a GTP-binding protein that is ubiquitously expressed in humans and other mammals. This study characterized the RHEB gene in the small abalone Haliotis diversicolor, and identified the responses of RHEB gene to hypoxia and thermal stresses.
CARIFICO co-managed fisheries

Facilitating Co-managed Fisheries in the Caribbean Region: Good Practices and Guidance from the CARIFICO Experience

This report documents outcomes from the Caribbean Fisheries Co-management Project (CARIFICO), a shared-governance approach to growing an offshore fishery reliant on fish aggregating devices (FADs).
Lake Apopka

Multiyear Oscillations in Depth Affect Water Quality in Lake Apopka

This study evaluated the effects of multiyear oscillations in depth on water quality in Lake Apopka. A 17-year record of monthly data on rainfall, mean depth, total phosphorus, total nitrogen, chlorophyll a, and Secchi disk transparency was used to quantify relationships.
