The Potential Impacts Of Soy Protein On Fish Gut Health, Vikas Kumar, Sakhawat Hossain, Janice A. Ragaza, Marina Rubio Benito
The Potential Impacts Of Soy Protein On Fish Gut Health, Vikas Kumar, Sakhawat Hossain, Janice A. Ragaza, Marina Rubio Benito
Biology Faculty Publications
Soy protein is the major source of protein as fishmeal replacement in fish feed because of its worldwide availability and low price. However, the presence of high carbohydrate content along with saponins, lectins, and phytates can have a negative impact on fish gut health. Based on the literature and our lab studies, dietary soybean meal can cause a dose-dependent type of distal intestine inflammation called enteritis in commercial fish species including salmonids. This leads to reduced absorptive capacity, increased mucus secretion, hyperpermeability, and leucocyte infiltration in the lamina propria and submucosa, also inducing the pro-inflammatory cytokine genes expression, including Il-1β, …

A 70-day feeding trial was conducted to evaluate the efficacy of Chlorella vulgaris supplementation in diets of giant freshwater prawn (Macrobrachium rosenbergii) post larvae. Resistance of the prawns against Aeromonas hydrophila and several immune parameters (total hemocyte count and prophenoloxidase activity) were also assessed in the study. Iso-nitrogenous, iso-lipidic, and iso-caloric prawn feeds were prepared utilizing a fishmeal based positive control diet (F0) and four dietary treatments with C. vulgaris inclusion levels of 2 (F2), 4 (F4), 6 (F6), and 8 (F8) %. Post larvae of M. rosenbergii were stocked randomly (mean initial body weight of 0.39 ± …
Fish Community Composition And Structure Near A Freshwater River Diversion In Southeastern Louisiana, Rachel L. Snider
Fish Community Composition And Structure Near A Freshwater River Diversion In Southeastern Louisiana, Rachel L. Snider
LSU Master's Theses
Gulf of Mexico estuaries, particularly in Louisiana, are among the world’s most productive, with landings of commercially- and recreationally-important species exceeding all other contiguous US states. Coastal wetlands are disappearing at an alarming rate because they have been impounded from Mississippi River water and sediment. Although controversial, one proposed solution is to re-route the Mississippi River through diversions and siphons to supply the freshwater and sediments necessary to rebuild vanishing wetlands, particularly in Barataria Bay and Breton Sound, LA. This strategy is one approach outlined in the Louisiana Coastal Master Plan. This project aimed to describe the composition and structure …

Physiological And Behavioral Correlates Of Hif-1 Alpha Protein Levels In The Gulf Killifish, Fundulus Grandis, Jasmine Harris
Physiological And Behavioral Correlates Of Hif-1 Alpha Protein Levels In The Gulf Killifish, Fundulus Grandis, Jasmine Harris
University of New Orleans Theses and Dissertations
Although the hypoxia-inducible transcription factor (HIF) orchestrates molecular responses to low oxygen, the amount of HIF-1α protein expressed during hypoxia varies among species, individuals, and tissues. This study measured HIF-1α protein levels along with several physiological and behavioral variables in the estuarine fish Fundulus grandis under normoxia (> 7 mg l-1 dissolved oxygen) and hypoxia (1 mg l-1 dissolved oxygen). Fish under hypoxic conditions had higher tissue levels of HIF-1α, hematocrit, blood glucose, blood lactate, frequency of aquatic surface respiration (ASR), and lower activity than normoxic controls. Under hypoxia, HIF-1α abundance in gill was positively correlated with body …
Effect Of Fire Suppression On Aquatic Invertebrates In Ephemeral Wetlands Embedded In Longleaf Pine Forests, Hailey E. Baker
Effect Of Fire Suppression On Aquatic Invertebrates In Ephemeral Wetlands Embedded In Longleaf Pine Forests, Hailey E. Baker
Honors College Theses
It has been established for many years that longleaf pine forests require the ecological disturbance of fire in order to maintain a balanced ecosystem. However, a crucial part of these forests has become nearly excluded from prescribed burning. Ephemeral wetlands embedded within longleaf pine forests are a unique and dynamic seasonal habitat that provide homes, refuge, and breeding grounds for a large array of taxa. Past research suggests that fire suppression around ephemeral wetlands is causing harm to many species of amphibians and other herpetofauna, especially threatened species like the flatwoods salamander. However, other species have not been as well …

Yellow Perch, Perca Flavescens, Growth And Survival On Different Feeds And In Low Salinity Environments, Peter Luther Shep
Yellow Perch, Perca Flavescens, Growth And Survival On Different Feeds And In Low Salinity Environments, Peter Luther Shep
Theses and Dissertations
The development of effective culture techniques in the rearing of yellow perch (Perca flavescens) (Mitchill 1814) has multi-lateral benefits including enriching recreational resources, helping conservation efforts, as well as providing quality sea-food production. A myriad of challenges is yet to be remediated if yellow perch aquaculture is going to prosper. One of the challenges that hinders yellow perch aquaculture is the lacking supply of high-quality fingerlings. With current techniques employed by yellow perch hatcheries, the survival of yellow perch up to 30-day post hatch (DPH) age is typically less than 10%. Furthermore, larval culture has depended on imported dry feed …

The Impact Of Nicotine Accumulation Exposure On Lithobates Catebeianus Larvae Mortality, Luke Micek
The Impact Of Nicotine Accumulation Exposure On Lithobates Catebeianus Larvae Mortality, Luke Micek
UCARE Research Products
Cigarette butts are the most littered item in the world and contain over 4,000 chemicals, including the organic compound nicotine (Slaughter et al. 2011). Billions of cigarette butts are littered each year which may wash into bodies of water, impacting the local wildlife. To determine how introduced chemicals impact the environment, it is important to study its effects on indicator species. Amphibians, such as Lithobates catebeianus, act as indicator species due to their extreme sensitivity to chemical changes in its environment. The purpose of this research project was to obtain data to help determine the impact nicotine accumulation has …

Improving Growth And Survival Of Cultured Yellow Lampmussel (Lampsilis Cariosa) For Restoring Populations, Virginia Martell
Improving Growth And Survival Of Cultured Yellow Lampmussel (Lampsilis Cariosa) For Restoring Populations, Virginia Martell
Masters Theses
In North America 72% of freshwater mussel species are endangered, threatened, or of special concern due to factors such as habitat loss and degradation, biological invasion, and land use change. Propagation of freshwater mussels has been considered a necessary conservation strategy for population restoration where threats have been mitigated but small population sizes limit population viability. Yellow lampmussel is a species of freshwater mussel that is endangered, threatened, or imperiled throughout its range; therefore, I evaluated laboratory techniques (probiotic supplements and secondary rearing designs) to improve culture of yellow lampmussel for population restoration. Several aquaculture facilities commonly use probiotics; thus, …
Fishes Of The Dakotas, Kathryn Schlafke
Fishes Of The Dakotas, Kathryn Schlafke
Electronic Theses and Dissertations
Biological reference materials play a critical role in studies of species biodiversity, biology, distribution, and historic diversity. Since the publications Fishes of North Dakota (Hankinson, 1929) and Fishes of South Dakota (Bailey and Allum, 1962), no new books have attempted to update the knowledge gained from the past decades of fish surveys and incorporate georeferenced collections at the state level. The last published book with the most complete accounts of fishes from North Dakota and South Dakota is the Distribution of Fishes in North and South Dakota Basins affected by the Garrison Diversion Unit (Owen et al. 1981) which includes …

Search For Selection: Genomic, Transcriptomic, And Phenotypic Investigations Of Spotted Seatrout (Cynoscion Nebulosus), Jingwei Song
Dissertations, Theses, and Masters Projects
Climate change has resulted in both increased mean water temperature and higher frequencies of extreme water temperatures in coastal areas. These new thermal regimes exert strong selective pressure on the thermal physiology of coastal aquatic species. Phenotypic plasticity (the ability of one genotype to display multiple phenotypes) and local adaptation (increased fitness to local environment due to natural selection) dictate both short-term (from hours to days to weeks) and long-term (from years to decades) resilience of a species. To better predict how a species will respond to the negative impacts of climate change, one first needs to know the current …
The Effects Of Light Level And Temperature On Freshwater Microbial Biomass, Production, Enzyme Activity, And Community Composition, Joel Bonney
Master's Theses and Doctoral Dissertations
Algae can stimulate the production of heterotrophic microbes in periphyton communities, but the synergistic effects of light and temperature on this phenomenon are not well understood and have implications on carbon cycling and energy flow. We employed recirculating mesocosms held at different temperatures and light levels and filled with Typha litter and attached microbes to assess these effects. Heterotrophic microbial production was greater in the presence of light, as were some periphytic enzyme activities. Few response variables increased in a near-linear fashion with ascending temperature, suggesting different temperature optima. The strength of heterotrophic microbial production responses to algal photosynthesis did …

Direct And Indirect Effects Of Sex Steroids On Gonadotrope Cell Plasticity In The Teleost Fish Pituitary, Romain Fontaine, Muhammad Rahmad Royan, Kristine Von Krogh, Finn-Arne Weltzien, Dianne M. Baker
Biological Sciences Research
The pituitary gland controls many important physiological processes in vertebrates, including growth, homeostasis, and reproduction. As in mammals, the teleost pituitary exhibits a high degree of plasticity. This plasticity permits changes in hormone production and secretion necessary to meet the fluctuating demands over the life of an animal. Pituitary plasticity is achieved at both cellular and population levels. At the cellular level, hormone synthesis and release can be regulated via changes in cell composition to modulate both sensitivity and response to different signals. At the cell population level, the number of cells producing a given hormone can change due to …
