Consumer Perceptions Of Hemp-Fed Aquaculture, Jillian Hyink
Graduate Theses and Dissertations
Global demand for seafood has increased significantly over the past several decades and is projected to continue rising in the future. The volume of aquaculture production has also particularly increased to meet this demand in the United States and globally, offering a relatively sustainable supplement to wild fish supplies. However, conventional fish farming uses unsustainable quantities of fishmeal and fish oil as feed inputs, which raises the cost of production and introduces safety concerns associated with fish consumption. One currently underexplored potential alternative to fishmeal is hemp grain, which can provide an affordable and nutritious feed for carnivorous fish and …

Fisheries Research Articles
Obtaining reliable estimates of the effective number of breeders (Nb) and generational effective population size (Ne) for fishery-important species is challenging because they are often iteroparous and highly abundant, which can lead to bias and imprecision. However, recent advances in understanding of these parameters, as well as the development of bias correction methods, have improved the capacity to generate reliable estimates. We utilized samples of both single-cohort young of the year and mixed-age adults from two geographically and genetically isolated stocks of the Australasian snapper (Chrysophrys auratus) to investigate the feasibility of generating reliable Nb and Ne estimates for a …

Conservation Genomic Investigation Of A Threatened Trout Species Endemic To The Gila River, David Thomas Camak
Biology ETDs
Climate change is a looming threat to the persistence of species, especially aquatic, imperiled species. Species native to desert streams are at a particular disadvantage, as many species already face drought, floods, wildfires, and threats from nonnative species, all of which are thought to be exacerbated by climate change. Species such as the threatened Gila Trout (Oncorhynchus gilae) already have small ranges and persist in fragmented and isolated habitats that limits gene flow between populations. Therefore, it is important to understand the current genomic status of such populations to be able to predict the future effects of climate …

School of Natural Resources: Dissertations, Theses, and Student Research
Silver Carp Hypophthalmichthys molitrix and Bighead Carp H. nobilis, collectively referred to as bigheaded carp, are invasive species in the United States of America that have expanded their range throughout the Missouri River basin in the last three decades. It may be desirable to develop management plans directed at the monitoring, control, or removal of bigheaded carp within the Missouri River basin. However, a knowledge gap exists regarding bigheaded carp ecology in Missouri River tributaries, which may be important for the development of management plans. As such, this study characterized bigheaded carp population demographics, occupancy, and connectivity in …

Modeling Pelagic Feeding In The Gulf Of Mexico With Implications For Ecosystem-Based Fisheries Management, Rebecca L. Scott
USF Tampa Graduate Theses and Dissertations
The focus of this dissertation was simulating trophic dynamics in the pelagic Gulf of Mexico (GOM) with an emphasis on ecosystem-based fishery management (EBFM) strategies for large pelagic species. Fisheries management in the United States largely utilizes single-species assessments, although managers are increasingly interested in EBFM approaches to better account for ecosystem effects on stocks such as predator/prey dynamics. Production in the surface layer of the pelagic zone is variable with environmental conditions and prey is often concentrated in patches by hydrodynamic features. Production is also transported vertically via diel vertical migration, during which deep-sea species provide potentially key forage …

The Philippine Agricultural Scientist
The silver therapon, Leiopotherapon plumbeus, is a new species for aquaculture. However, information on the optimal conditions for the transport of this species for grow-out culture needs to be established to avoid stress and unnecessary mortalities. This study examined the effects of duration of transport and loading density on survival and water quality during simulated transport of silver therapon. Hatchery-produced fingerlings [1.30 ± 0.34 g body weight (BW); 44.30 ± 3.77 mm total length (TL)] were held in double-layered oxygenated plastic bags at three transport durations (6 h, 9 h, and 12 h) and densities (40, 80, and 120 …

Two endemic, “large river” fishes of the Colorado River basin of western North America, bonytail Gila elegans and razorback sucker Xyrauchen texanus, are among several critically endangered species in the system. Wild populations of bonytail are gone, and there are no self-sustaining populations of razorback sucker anywhere; reproduction occurs but recruitment does not. Both species have been under intensive management in the Lower Colorado River since the 1980s. Today, with the single exception of Lake Mead, remaining populations are composed entirely of repatriated individuals that depend on stocking for their continued existence. In 2003, a conceptual off-channel habitat (OCH) …

Freshwater mussels are one of the most imperiled taxonomic groups in the world, consequently, much effort is being expended to document the distribution of many mussel species. One tool that can aid in characterizing mussel distributions are species distribution models (SDM). I conducted two studies pertaining to freshwater mussel distributions: (1) utilize Maximum Entropy (MAXENT) modeling to predict potential areas of suitable habitat for the threatened Ouachita Fanshell (Cyprogenia sp cf aberti), and (2) survey small tributaries of the Ouachita River watershed to fill a portion of the information gap surrounding mussel communities in under-surveyed streams. Through changing …

Ancient Wisdom, Modern Prosperity: Harnessing Traditional Ecological Knowledge To Revitalize Australia's Economy, Environment, And Human Wellbeing, Annabelle L. Baulch
Student Theses 2015-Present
This paper explores the traditional knowledge of Australia’s Indigenous people and how it can improve Australia's environment, health, and economic prosperity to shape a more sustainable future. Indigenous Australians managed the land for thousands of years; however, being forced off the land following European colonization resulted in terrible cultural, social, and environmental disruption for Aboriginal Australians and made conservation efforts difficult. Wildfires, imported species, mining, and agriculture is steadily destroying the Australian ecosystem, contributing to climate change, species extinction, and gaps in our cultural and ancestral knowledge. Chapter One overviews Australia's environmental issues; it uses quantitative data to explore the …

2024 Spring Honors Capstone Projects - Archive
In this study, we investigated the color-changing capabilities of Trinidadian killifish, Anablepsoides hartii, through exposure to varied color conditions over defined periods of time. Our experiment aims to understand adaptive responses when killifish are subjected to different color backgrounds, exploring their mechanisms to change color. By subjecting the species to different environmental color variations, we sought to discern color change patterns, which could indicate adaptive responses related to camouflage, stress, behavior clues, and physiological adjustments. Carefully controlling environmental factors, we monitored and documented the fishes’ color changes, aiming to provide insights into the interplay between fish’s developmental plasticity and its …

Response Of Fish Assemblages To Increased Connectivity And Habitat Restoration In Bayou St. John, A Degraded Waterway In New Orleans, La, Alia Jones
LSU New Orleans Theses and Dissertations
Bayou St. John is a degraded waterway located within the City of New Orleans. The Bayou, which is disconnected from Lake Pontchartrain by floodgates, has undergone restoration efforts to improve connectivity through frequent floodgate openings and marsh habitat restoration outside of the floodgates. To assess possible responses of local fish assemblages to these restoration efforts, I analyzed long-term fish assemblage data from three sites located inside of the floodgates and one site located at the restored marsh outside of the floodgates. Two sites inside of the floodgates experienced significant changes in assemblages between the pre-opening period (2006-2012) and post-opening period …
