Exopolysaccharide From The Liquid Culture Of Ganoderma Lucidum As Feed Additive For Red Hybrid Tilapia (Oreochromis Sp.), Thiran Jaganath Puvanen

Student Works (2020-2029)

Feed additive plays a significant role in sustaining fish production. Exopolysaccharide (EPS) obtained from the fermented mycelium of Ganoderma lucidum produced by using submerged-liquid fermentation (SLF) was proposed as a feed additive in this study for red hybrid tilapia (Oreochromis sp.). Body composition, organosomatic indices, and haematological parameters were observed in fish fed with three different diets supplemented with EPS (1 g/kg, 2 g/kg, and 3 g/kg). Although higher concentration EPS feed was observed to produce minor effect on body composition and organosomatic indices, significant effect on both parameters was observed in fish fed with 1 g/kg diet. All diets …

Performance Of Mycelial Biomass From The Mushroom Ganoderma Lucidum As Feed Additive On Growth And Quality Of Red Hybrid Tilapia (Oreochromis Spp.), Yerima Grema

Student Works (2020-2029)

The present study describes the potentiality of dietary supplement of mycelial biomass of Ganoderma lucidum (MBGL) as functional feed additives formulated along with other feed ingredients at different inclusion levels (5g/kg diet, 10g/kg diet and 15g/kg diet). A hundred and twenty (120) red hybrid tilapia were used for this experiment in duplicates treatment. Fifteen fish were allocated to each tank with an average weight of 17.0g. A six (6) week feeding trial was conducted to evaluate the effect of GL biomass on red hybrid tilapia body composition, organosomatic index, as well as hematological indices. At the end of the feeding …

Expression Of Stress Related Genes Of Penaeus Varnamei In Biofloc Closed Breeding System, Truong An Nguyen

Student Works (2020-2029)

The Pacific shrimp Penaeus vannamei, which is also known as the whiteleg shrimp, is fast becoming a key species of shrimp farming worldwide since this species has been cultured widely in many countries, such as Mexico, America, especially in Southeast Asian countries including Thailand, Vietnam, and Malaysia. In addition, the shrimp aquaculture industry has applied many new cultural techniques, especially biofloc technology – which is an eco-friendly culture technique and has many advantages over other traditional methods, such as high productivity, the stable environment of the culture, and low levels of feed conversion. Unfortunately, for so many years, shrimp farming …

Authentication Of Red Snapper (Lutjanus Campechanus) Fillets Using A Combination Of Real-Time Pcr And Dna Barcoding, Rachel B. Isaacs, Rosalee S. Hellberg

Food Science Faculty Articles and Research

Red snapper (Lutjanus campechanus) is a historically overfished and highly valued species that is commonly substituted with other fish, such as tilapia, rockfish, and other snapper species. The objective of this study was to assess the ability of real-time PCR to be used as a screening tool to rapidly test commercial fillets for the presence of red snapper, followed by species identification of negative samples with DNA barcoding. A total of 24 frozen, fresh, or thawed (previously frozen) fillets labeled as “red snapper” were tested with real-time PCR, along with 54 fillets from fish that are common substitutes …

Physiological And Behavioral Correlates Of Hif-1 Alpha Protein Levels In The Gulf Killifish, Fundulus Grandis, Jasmine Harris

LSU 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 …

Size Selective Parasitism Of Rainbow Trout (Oncorhynchus Mykiss) By Chestnut Lampreys (Ichthyomyzon Castaneus) In An Artificial Setting, Jeremiah M. Salinger, Ronald L. Johnson

Southeastern Fishes Council Proceedings

Paradigms of optimal resource utilization by animals, both classical and more recent, were not originally developed in the context of parasitism. Though this oversight has slowly been reversed, little attention has been paid to optimal resource utilization by parasitic fishes, such as lampreys. Multiple explanations for host size selection by parasitic lampreys may be plausible, but results from previous studies have been inconsistent. We studied host size selection by Chestnut Lampreys (Ichthyomyzon castaneus) parasitizing Rainbow Trout (Oncorhynchus mykiss) in fish hatchery raceways in north central Arkansas during the late winter and early spring of 2013. Parasitized …

Movement Of Translocated Adult Sicklefin Redhorse (Moxostoma Sp.) In The Oconaluftee River, North Carolina: Implications For Species Restoration, Jessica L. Davis, David P. Gillette, C. Reed Rossell Jr., Michael J. Lavoie

Southeastern Fishes Council Proceedings

The Sicklefin Redhorse is a rare, undescribed species of Moxostoma, endemic to the Hiwassee and Little Tennessee River basins of western North Carolina and northern Georgia, where it has been eliminated from much of its native range. It is listed as endangered in Georgia and threatened in North Carolina. Although it has not been granted federal protected status, this species is the subject of a Candidate Conservation Agreement between federal, state, tribal, and private stakeholders, of which one objective calls for the re-establishment of Sicklefin Redhorse populations throughout its historical range. The objective of our study was to evaluate …

Status Of The Blackstripe (Fundulus Notatus) And Blackspotted (F. Olivaceus) Topminnows In The Ozark Uplands Of Central Missouri, Nathaniel Steffensmeier, Naznin Sultana Remex, Robert Hrabik, David D. Duvernell

Southeastern Fishes Council Proceedings

The topminnow species Fundulus notatus and F. olivaceus have broadly overlapping geographic distributions that extend throughout much of the central and southern United States. In the northern portion of their respective ranges, in Missouri, the regional distributions of the two species coincide largely with recognized ecoregions. In the unglaciated southern half of Missouri, F. olivaceus is distributed throughout Ozark upland habitats while F. notatus is abundant in marginal large river and prairie habitats along the Ozark borders. An exception to this partitioning is the historical report of abundant F. notatus in the Bourbeuse and upper Meramec River drainages within the …

The Gut Microbiome And Its Potential Role In Paradoxical Anaerobism In Pupfishes Of The Mojave Desert, Brian Hedlund

Life Sciences Faculty Research

Background: Pupfishes frequently enter paradoxical anaerobism in response to endogenously produced or exogenously supplied ethanol in a dose-dependent manner. To decipher the role of the gut microbiota in ethanol-associated paradoxical anaerobism, gut microbial communities were depleted using a cocktail of antibiotics and profiled using 16S rRNA gene sequencing. Results: Compared to the control group (n = 12), microbiota-depleted fish (n = 12) spent more time in paradoxical anaerobism. Our analysis indicated that the bacterial phyla Proteobacteria, Fusobacteria, Bacteroidetes, Firmicutes, Actinobacteria, Patescibacteria, and Dependentiae dominated the pupfish gut, which is consistent with other fish gut microbiota. Although the gut microbial communities …

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 …

Is Anyone Home? Year Round Site Fidelity Vs. Temporal Territories In Estuarine Blennies, Nicholas Govostes

Honors Theses

Temperate oyster reef blennies use articulated oyster shells as nest sites in warmer months during breeding season but little is known about their site fidelity during non-breeding season. Unlike coral reef blennies that occupy territories year-round, rocky intertidal temperate blenny species display temporal territories and seasonally migrate into breeding shelters. Striped blenny (Chasmodes bosquianus) shelter use was described from November 2019 through March 2020 at Oyster Landing, North Inlet estuary, SC to quantify the proportion of daylight hours when fish were in residence and describe potential relationships between shelter occupancy and neighboring fishes. Replicate PVC shelters were monitored …

Development Of Methods To Track Oyster Movement Under Field Conditions In North Inlet Estuary, South Carolina, Alyssa M. Leclaire

Honors Theses

Eastern oyster (Crassostrea virginica) reefs provide important habitat structure and ecosystem services in saltmarsh tidal creek estuaries. Reef persistence depends on growth of resident individuals and regular recruitment to maintain suitable shell substrate. Boat wakes potentially physically displace oyster clumps. The objective of this research was to develop methods to track oyster clump position and biomass on two natural fringing oyster reefs in North Inlet estuary, South Carolina. Boat traffic (number of boats making wakes per day), oyster clump displacement (cm/d) over time, oyster biomass (g dry tissue), and condition index (biomass/g dry shell weight) were quantified from …

A Social–Ecological Odyssey In Fisheries And Wildlife Management, Andrew K. Carlson, William W. Taylor, Melissa R. Cronin, Mitchell J. Eaton, Mark A. Kaemingk, Andrea J. Reid, Ashley Trudeau

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Aldo Leopold, famous ecologist and “father” of North American wildlife management, once said, “These are two things that interest me: the relation of people to each other, and the relation of people to land” (Leopold 1947). Ever prescient, Leopold recognized that natural resource management is fundamentally about humans and their relationship with nature well before conservation became an established way of thinking, much less the bedrock of entire professions. Similarly, amid the Green Revolution to increase agricultural production, in part, through widespread use of pesticides, renowned environmentalist and journalist Rachel Carson noted that we are all “a part of nature, …

Record Fledging Count From A Seven-Egg Clutch In The Cooper’S Hawk (Accipiter Cooperii), Robert N. Rosenfield, Sarah A. Sonsthagen, Ann Riddle-Berntsen, Evan Kuhel

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Cooper’s Hawks (Accipiter cooperii) typically lay 3–5 eggs per clutch, rarely 6 eggs, and there are 2 accounts of 7-egg clutches and 1 record of a maximum 8-egg clutch for the species. Brood sizes of 3–5 young are common and the previous maximum brood count is 6 young. However, in 2019, we found an urban nest in Stevens Point, Wisconsin, with 7 eggs that resulted in a record high of 7 fledglings. We genetically confirmed that the attending male sired all the offspring and the attending female laid all 7 eggs. Larger body size of the tending adults …

An Analysis Of Dredge Efficiency For Surfclam And Ocean Quahog Commercial Dredges, Leanne Poussard

Master's Theses

Between 1997 and 2011, The National Marine Fisheries Service conducted 50 depletion experiments to estimate survey gear efficiency and stock density for Atlantic surfclam (Spisula solidissima) and ocean quahog (Arctica islandica) populations using commercial hydraulic dredges. The Patch Model was formulated to estimate gear efficiency and organism density from the data. The range of efficiencies estimated is substantial, leading to uncertainty in the application of these estimates in stock assessment. Analysis of depletion experiment simulations showed that uncertainty in the estimates of gear efficiency from depletion experiments was reduced by higher numbers of dredge tows per experiment, more tow overlap …

Evaluating Methods To Reduce Humpback Whale (Megaptera Novaeamgliae) Ship Strike Mortality In Nearshore Feeding Habitats Within The San Francisco Bay, Alisa Keenan

Master's Theses

Across our world’s oceans, whales are perpetually stuck and killed by large ships. Sea-based commercial trade is increasing on a global scale; therefore, more large ships are circumnavigating through biologically important whale habitats. This is of grave concern to marine resource managers, especially in the United States where major shipping corridors overlap critical whale habitat. It is feared that in these areas with high whale density, ship strikes are reducing populations of whales to levels below what is sustainable for threatened and endangered species, thereby hindering the recovery of depleted whale populations. Humpback whales, a species that is federally-listed as …

Maturation Spawning And Larviculture Of Atlantic Croaker (Micropogonias Undulatus) At Low Salinity, Edithrose Fairweather

Master's Theses

Atlantic Croaker is a popular baitfish among anglers targeting a variety of gamefish in the Gulf of Mexico. Aquaculture of this species could help meet the demand for Croaker, especially during winter when wild-caught Croaker are unavailable. Currently, Croaker aquaculture involves broodstock maturation, spawning, and larval culture at high salinity. This protocol prevents the direct use of coastal water for culture along the Mississippi Gulf coast where salinity is low. This study examined the feasibility of performing hatchery production of Atlantic Croaker at low salinity.

Culture of Croaker broodstock at 10, 20, and 30 psu during the maturation period was …

Bleaching Susceptibility Of Aquarium Corals Collected Across Northern Australia, Morgan S. Pratchett, Ciemon F. Caballes, Stephen J. Newman, Shaun Wilson, Vanessa Messmer, Deborah J. Pratchett

Fisheries Research Articles

There are a wide range of Scleractinian corals that are collected for the global reef aquarium market, often from non-reefal environments. The sustainability of coral harvesting is potentially threatened by increasing anthropogenic disturbances and climate change, though it is unknown to what extent many commonly harvested corals are susceptible to environmental change, or actually bleach during marine heatwaves. In this study, we experimentally tested the temperature sensitivity and bleaching susceptibility of six coral species (Homophyllia australis, Micromussa lordhowensis, Catalaphyllia jardinei, Trachyphyllia geoffroyi, Duncanopsammia axifuga, and Euphyllia glabrescens), which are important components of the …

Predation Efficiency And Prey Choice Of Estuarine Organisms Under Varying Anthropogenic Light Types And Intensities, Carmen Montalvo

HCNSO Student Theses and Dissertations

The coastlines of Florida are becoming highly urbanized, and the growing human population is affecting many mangrove and estuarine habitats. Exploring the predation efficiency and prey choice of estuarine organisms under varying anthropogenic light types and intensities could help determine anthropogenic effects. Mangrove habitats support both relatively large predators such as Blue Striped Grunt (Haemulon sciurus) and Gray Snapper (Lutjanus griseus), and a diversity of smaller taxa that occupy lower trophic levels, including Grass Shrimp (Palaemonetes paludosus) and Mosquitofish (Gambusia holbrooki). Understanding how predation (or predation evasion) efficiencies are affected by different …
