Recreational Rights to the Dry Sand Beach in Florida: Property, Custom and Controversy

Last year, an amendment to the Florida Community Planning Act sparked controversy due to a perceived land grab over the public’s right to access Florida’s beaches. This paper describes interpretive issues the amendment may raise and possible solutions.
common snook

Shifts in the Skin-Associated Microbiota of Hatchery-Reared Common Snook Centropomus undecimalis During Acclimation to the Wild

Microbiota on fish skin can prevent the spread of harmful bacteria during stock enhancement. This study investigated microbiota structure during the acclimation of juvenile hatchery-reared common snook to the wild.

Health Characteristics and Blood Bacterial Assemblages of Healthy Captive Red Drum: Implications for Aquaculture and Fish Health Management

This study characterized the blood microbiota and blood characteristics of healthy captive Red Drum, Sciaenops ocellatus, an economically significant fish species in the Gulf of Mexico.
Sunray Venus Clams

The Sunray Venus Clam, Macrocallista nimbosa, Exhibits Asynchronous Spawning

Due to its reputation as an unreliable spawner, the production of the sunray venus clam has stalled. This study provides a more thorough description of its reproductive cycle to determine the cause of spawning difficulties.
Endangered Xenotoca eiseni

Activation of Free Sperm and Dissociation of Sperm Bundles (Spermatozeugmata) of an Endangered Viviparous Fish, Xenotoca eiseni

Knowledge of sperm motility activation for viviparous fishes has been limited. This study used the endangered Redtail Splitfin as a model to investigate the activation of sperm from viviparous fishes.
Flood Sign

Characterization of Coastal Flood Damage States for Residential Buildings

Post-disaster surveys following coastal floods are often based on qualitative descriptions. This paper describes a method to quantify damages and apply that data to the Florida Public Hurricane Loss Model.
Hurricane Damage

Overview of Damage Observed in Regional Construction During the Passage of Hurricane Irma over the State of Florida

After Hurricane Irma, reconnaissance teams assessed damage using a smartphone application. This study presents the geospatial distribution of the observed damage.
Aquaculture Research Hard Clam

Cryopreservation of Trochophore Larvae from the Hard Clam Mercenaria mercenaria: Evaluation of the Cryoprotectant Toxicity, Cooling Rate and Thawing Temperature

Hard clam aquaculture is a $65 million industry along the east coast and Gulf of Mexico. This study developed a preliminary protocol to cryopreserve trochophore larvae of hard clams for genetic breeding and seed production.
Small Sawfish Catch

Physiological Stress in the Smalltooth Sawfish: Effects of Ontogeny, Capture Method, and Habitat Quality

The smalltooth sawfish is sensitive to dramatic population declines from overfishing and habitat loss, but the physiological stress response to these challenges is unknown. This study examined basic stress physiology in response to different fishing gears, degraded habitat and water quality.

Growth and Reproduction of Echeneis naucrates from the Eastern Gulf of Mexico

Remoras are difficult to study as they hitchhike on sharks, bony fishes, sea turtles and dolphins. This study quantified the growth and reproductive characteristics of the live sharksucker to evaluate potential indirect human-caused impacts on remora populations.
Spiny lobster

Partial Validation of a TaqMan Real-Time Quantitative PCR Assay for the Detection of Panulirus argus virus 1

The Caribbean spiny lobster is the only known host for Panulirus argus virus 1. This study developed a real-time polymerase chain reaction assay to detect and quantify PaV1 infection severity in Caribbean spiny lobsters.
White spots infection

White Spot Syndrome Virus and the Caribbean Spiny Lobster, Panulirus argus: Susceptibility and Behavioral Immunity

White Spot Syndrome Virus has not been documented in wild spiny lobsters, but has been experimentally transmitted. This study assessed the risk to P. argus via injection and waterborne transmission.
Brine Shrimp

Storage of Decapsulated Artemia (Brine Shrimp)

Artemia (brine shrimp) are used as a food source for the larval stages of many fishes. This publication provides a step-by-step overview of methods to store decapsulated Artemia eggs for a short time period and eliminate the need to decapsulate daily.

Hurricane Impacts on Florida's Agriculture and Natural Resources

Hurricanes can directly impact both inland and coastal areas. This publication reviews basic facts about hurricanes and discusses ways they might affect Florida’s agriculture and natural resources.
Water Flooding and Lowrise Buildings

Simulation of Rain Penetration and Associated Damage in Buildings within a Hurricane Vulnerability Model

Recent tests quantified hurricane damage to low-rise buildings. This study incorporates those test results into the Florida Public Hurricane Loss Model to estimate the volume of wind-driven rain that enters buildings.
Barotrauma and the Successful Release of Fish Caught in Deep Water

Insights from a Stated Preference Experiment of Florida Residents: Role of Information and Incentives in Hurricane Risk Mitigation

To maximize the use of constrained funding allocated for resilience policies, this paper uses online survey responses from Florida households to explore the effectiveness of vulnerability information and financial assistance programs to facilitate hurricane risk mitigation.
Tiger Shark

A Comparison of Reproductive and Energetic States in a Marine Apex Predator (the Tiger Shark, Galeocerdo cuvier)

Information on the relationship between the reproductive and energetic states for most shark species is lacking. This study used a noninvasive approach to assess these relationships in free-ranging female tiger sharks.
Gulf of Mexico Fishing

Modeling Temporal Closures in a Multispecies Recreational Fishery Reveals Tradeoffs Associated with Species Seasonality and Angler Effort Dynamics

The Gulf of Mexico recreational reef fishery is partly regulated by seasonal species-specific harvest closures, which may be ineffective due to discard mortality of non-target fishes. This study evaluated whether complete bottom fishing closures might improve stock status of multiple species.
Crystal River Mound

A First Millennium A.D. Vegetation History from the Crystal River Site (8CI1), Florida

Vegetation histories offer valuable records of landscape transformations driven by climate, sea-level changes, and human-caused modifications. This study developed a paleo-historical-ecological reconstruction from a fossil pollen analysis at a mound center near Crystal River.
Acropora cervicornis

Acropora cervicornis Genet Performance and Symbiont Identity Throughout the Restoration Process

Intraspecific diversity in host and symbiont is an important consideration for coral nurseries. This study built upon a previous study that quantified Acropora cervicornis growth phenotypes by outplanting the same genets across two reef sites and tracking their performance for one year.
Zebra Fish

Changes to Extender, Cryoprotective Medium, and In Vitro Fertilization Improve Zebrafish Sperm Cryopreservation

Sperm cryopreservation is a method for preserving genetic resources in aquaculture. But zebrafish cryopreservation methods have produced low fertilization rates. This study developed a new extender and cryoprotective medium to improve the post-thaw in vitro fertilization process.
Fisheries Research Book Cover

Density-Dependence in the Life History of Fishes: When is a Fish Recruited?

Age or size at recruitment is an important element of fisheries models and stock assessments. However, little guidance exists for when, biologically, a fish is recruited. This study provides guidance for determining an appropriate size or age at recruitment.
Acropora palmata Coral

Sucessful Demonstration of Assisted Gene Flow in the Threatened Coral Acropora palmata Across Genetically-Isolated Caribbean Populations Using Cryopreserved Sperm

Assisted Gene Flow is a viable tool to help corals adapt to changing environments. This study tested whether cryopreserved coral sperm could facilitate assisted gene flow between genetically-isolated populations of a Caribbean coral.
Cuban Bonefish

Age, Growth, and Age at Maturity of Bonefish (Albula species) Among Cuban Habitats

Growth rates of bonefish in Cuba differ among locations where they have been studied, but many locations have not yet been examined. This study investigated the different growth rates of bonefish in Cuba to allow for better management of the species.
