Reported Incidences Of Parasitic Infections In Marine Mammals From 1892 To 1978, John R. Felix

Zea E-Books Collection

The role of parasites in the lives and deaths of marine mammals has been scrutinized by biologists for decades, but the scientific literature prior to 1978 has been difficult to acquire and time-consuming to search. Now this new and extensive bibliography gives researchers a convenient resource for reviewing the classical literature on parasites of marine mammals so that historical infection prevalence and geographical distribution can be easily and properly assessed. This book contains detailed information about accepted (or suspected) taxonomic synonyms and geographical information about the host and/or parasite, covering the parasite groups Acanthocephala, Acarina, Anoplura, Cestoda, Nematoda, and Trematoda, …

Ccaat/Enhancer-Binding Protein Delta (C/Ebp-Delta) Expression In Antarctic Fishes: Implications For Cell Cycle And Apoptosis, Isaac Martin Sleadd

Dissertations and Theses

Chapter 1: Antarctic fishes are extremely cold adapted. Despite their inability to upregulate heat shock proteins, recent studies have demonstrated a capacity for heat response in these animals. A cDNA microarray study looked at the Notothenioid fish Trematomus bernacchii and revealed heat sensitivities for hundreds of genes, two of which code for members of the CCAAT/Enhancer-binding protein (C/EBP) family of transcription factors. These molecular switches are best known for their roles in apoptosis, inflammation and cell cycle arrest. This dissertation further elucidates the role of C/EBP-delta in the Antarctic fishes T. bernacchii and Pagothenia borchgrevinki.

Chapter 2: C/EBP-delta is constitutively …

Fish Species Distribution In Seagrass Habitats Of Chesapeake Bay Are Structured By Abiotic And Biotic Factors, Jason J. Schaffler, Jacques Van Montfrans, Cynthia M. Jones, Robert J. Orth

OES Faculty Publications

Seagrass habitats have long been known to serve as nursery habitats for juvenile fish by providing refuges from predation and areas of high forage abundance. However, comparatively less is known about other factors structuring fish communities that make extensive use of seagrass as nursery habitat. We examined both physical and biological factors that may structure the juvenile seagrass-associated fish communities across a synoptic-scale multiyear study in lower Chesapeake Bay. Across 3years of sampling, we collected 21,153 fish from 31 species. Silver Perch Bairdiella chrysoura made up over 86% of all individuals collected. Nine additional species made up at least 1% …

Assessment Of Sea Lice Infestations On Wild Fishes Of Cobscook Bay, Alexander Jensen

Honors College

Sea lice are ectoparasitic copepods on fishes and can negatively impact aquaculture operations. Little work on sea lice, specifically Lepeophtheirus salmonis and Caligus elongatus, has occurred in the northwest Atlantic. This project characterized sea lice infestations on wild fishes in Cobscook Bay during 2012. Trawling, seine netting, and fyke netting occurred from March to November. Netting sites were selected to sample the bay’s three regions: Outer, Central, and Inner Bay. Visual examinations of fish were used to identify wild hosts and characterize sea lice life stage abundances, attachment locations, and infection prevalence and intensity. DNA sequencing was used to …

Investigation Of Early Development And Importance Of Sediment Choice In The Hatchery Production Of Razor Clams, Ensis Directus, Molly P. Flanagan

Honors College

Ensis directus, commonly known as the razor clam, is a bivalve species that lives in temperate sub-polar regions of the Atlantic Ocean. It is an infaunal species found in shallow, subtidal, sedimentary habitats. A recent increase in the market value for razor clams has resulted in heightened interest in the culture of this species. The experimental hatchery at the University of Maine’s Darling Marine Center began work in 2012 to develop improved hatchery and grow-out techniques for this species. For my thesis, razor clam embryos from both spontaneous and controlled spawns were observed via video and still imagery to document …

Diet And Prey Availability Of Sturgeons In The Penobscot River, Maine, Matthew Dzaugis

Honors College

Although vital to the protection and conservation of species listed under the U.S. Endangered Species Act, critical habitat of shortnose sturgeon and Atlantic sturgeon in the Penobscot River, Maine have not yet been described. Critical habitat includes food availability as well as the physical characteristics of foraging habitat. To characterize seasonal availability of benthic prey, a ponar grab was used to collect over 125 benthic samples between 21 May and 8 October 2012. Samples were stratified throughout the river and broadly categorized by sediment type. All organisms within samples were identified to the family level. To characterize diet, stomach contents …

Economic Efficiency In Fisheries And Aquaculture, Paul Molyneaux

The Catch

Reflection of the author as a worker looking to make the best use of his time and energy. His innate understanding of the principles of ecological economics followed by exposure to the discipline’s advancing theories leads to a revelation regarding the backwards logic of fisheries and aquaculture policy thus far, and the decline in real seafood production.Along with many others, Molyneaux looks to ecological economics to create a new paradigm for sustainable fisheries.

Bacterial Community Profiling Of The Eastern Oyster (Crassostrea Virginica): Comparison Of Culture-Dependent And Culture-Independent Outcomes, Kenneth J. La Valley, Steve Jones, Marta Gomez-Chiarri, Joseph Dealteris, Michael A. Rice

Michael A Rice

Tissue-associated bacterial community profiles generated using a nested polymerase chain reaction–denaturing gradient gel electrophoresis (DGGE) approach and culture-dependent and culture-independent isolation techniques were compared. Oyster samples were collected from 2 harvest areas along the coast of Maine, in the United States. Profiles from both isolation strategies were evaluated using Sorensen’s index of similarity and cluster analysis of gel banding patterns. Cultureindependent profiles were further evaluated using the Shannon diversity index. In general, the culture-dependent strategy resulted in a greater number of bands within a profile. BacterialDGGEprofiles were found to be highly similar within an isolation strategy, with a higher degree …

Gonadal Cycle Of Northern Quahogs, Mercenaria Mercenaria (Linne, 1758), From Fished And Non-Fished Subpopulations In Narragansett Bay, Dora Marroquin-Mora, Michael Rice

Michael A Rice

To determine if population density in areas closed to fishing in Narragansett Bay is causing differences in the reproductive potential of the organisms, this study used two approaches to determine the reproductive condition of the animals. The first approach consisted in employing a gravimetric condition index (CI) to evaluate the general condition of quahogs from nine different sites, 3 sites open conditionally for fishing (conditional areas) and 6 sites closed to fishing. The second approach was a determination of gonadal index (GI) of a subset of the sample sites, by histological observation of gonadal tissue sections. Initial sampling included determination …

Bioremediation Mariculture In Zanzibar, Tanzania: A Viability Assessment Of Using Bath Sponge And Pearl Oyster Farms To Filter Highly Olluted Waters In The Zanzibar Channel, Hayley Oakland

Independent Study Project (ISP) Collection

Bioremediation of polluted water off the coastline of the urban center of Zanzibar—Stone Town, Unguja—was assessed for implementation feasibility through bath sponge and pearl oyster mariculture. A vast research base of the city’s coastal area exists, including the pollution concentrations at various locations, the ramifications of this pollution on the fringing ecosystems, and the relevant water circulation system of eddies and passageways produced by the north flowing East African Counter Current. In following the experimental examples of bioremediation projects around the world, this study tested facets of the filtration abilities of marine sponges and oysters. Both organisms suggested strong pollution …

Behavioural Salinity Preferences Of Juvenile Green Sturgeon Acipenser Medirostris Acclimated To Fresh Water And Full-Strength Salt Water, J. B. Poletto, D. E. Cocherell, A. P. Klimley, J. J. Cech Jr., N. A. Fangue

School of Natural Resources: Faculty Publications

To quantify the salinity preference of juvenile green sturgeon Acipenser medirostris, two groups of A. medirostris [140 days post hatch (dph); total length (L_T) 38.0–52.5 cm] were acclimated to either near fresh water (mean ± S.E. salinity = 3.2 ± 0.6) or full-strength salt water (34.1 ± 1.2) over 8 weeks. Following acclimation, the two groups were divided into experimental and control groups, where experimental A. medirostris from both freshwater and saltwater acclimations were individually introduced (200–220 dph) into a rectangular salinity-preference flume (maximum salinity gradient: 5–33). Control A. medirostris were presented with only their acclimation …

Systematic Ichthyofaunal Surveys In Urban And Non-Urban Watersheds, Eugene G. Maurakis, David V. Grimes, Amanda Schutt, Suzy Short

Virginia Journal of Science

Objectives were to model fish species richness relative to natural and anthropogenic variables in Quantico Creek, a forested undisturbed stream environment, and Cameron Run, a highly disturbed urban stream environment in the lower Piedmont-Fall Line region of the Potomac River watershed. Species richness in all stream orders (e.g. avg. range=2.5-9.65 in 1st-3rd orders) of Quantico Creek were significantly higher than those (e.g. avg. range=2.1- 7.6 in 1st -4th orders) of Cameron Run. Fish species richness in Quantico Creek watershed can be modeled by eight factors: season, stream order, elevation, river km, stream width and depth, watershed size, and percent of …

Assessing The Habitat Use, Diet, And Sex Ratios Of Atlantic (Acipenser Oxyrinchus) And Shortnose Sturgeon (Acipenser Brevirostrum) In The Saco River, Me, Caitlyn Little

All Theses And Dissertations

Due to the questionable status of sturgeon populations along the east coast of the United States, there has been considerable research focus on these species in recent years. Previous studies have overlooked the Saco River as an important habitat for sturgeon in the Gulf of Maine. However, the incidental capture of a sturgeon in the Saco River in the fall of 2007 raised questions about the presence of this species and the role that the Saco River might play in the life cycle of these fish. The goals of this thesis were to evaluate the utilization of this habitat by …

The Relationship Between Ocean-Climate Indices And Diet Of Rhinoceros Auklets (Cerorhinca Monocerata) , Christine Anderson

Summer Research

Marine system productivity varies as a result of changing ocean-climate indices and cascade through trophic levels, impacting marine mammals and birds. Rhinoceros Auklets (Cerorhinca monocerata) are nesting seabirds in the North Pacific and can indicate variation in marine conditions via diet composition. I will analyze the relationship of Rhinoceros Auklet diets and ocean-climate indices by comparing diet composition and diversity on two islands in differing marine systems. I will also use oceanographic indices to evaluate any correlations between ocean-climate effects and diet variability in populations, providing insights into what physical forcing mechanisms may affect diet, and ultimately reproductive performance, of …
