Reproductive Life History Of Fundulus Jenkensi And Comparative Development Of Five Sympatric Fundulid Species, Eric Thomas Lang

Master's Theses

Fundulus jenkinsi is recognized federally and within the state of Mississippi as a Species of Concern. Little is known about the life history of this coastal killifish, but a detailed reproductive histology study of F. jenkinsi and a diagnostic key of the early life stages of select members of Fundulidae can provide the foundation needed to accurately identify it and quantify reproductive parameters in this rare species in need of conservation. Monthly gonadosomatic index (GSI) of male and female F. jenkinsi were documented, and spawning phases and oocyte stages were examined using reproductive histology. In addition, various stages of …

Diatoms As Indicators Of Water-Level Change In Freshwater Lakes, Julie A. Wolin, Jeffrey R. Stone

Biological, Geological, and Environmental Faculty Publications

Water-level changes result from a variety of geological, biological, and/or climatic processes. Many of these changes occur over long periods; others may be rapid or result from catastrophic events. In aquatic environments, diatoms are highly sensitive indicator organisms and their microfossils, deposited in lake sediments, can be used to infer environmental changes (Smol, 2008). Unambiguous diatom signals can be reconstructed from lakes isolated from marine or brackish waters (e.g. Fritz et al., this volume; Horton & Sawai, this volume). However, in freshwater systems lake-level changes are often recorded as increases in planktonic (free-floating) diatoms – although as discussed below, interpretation …

Match–Mismatch Regulation For Bluegill And Yellow Perch Larvae And Their Prey In Sandhill Lakes, Jeffrey C. Jolley, David W. Willis, Richard S. Holland

Nebraska Game and Parks Commission: Staff Research Publications

Food availability may regulate fish recruitment, both directly and indirectly. The availability of zooplankton, especially to newly hatched larvae, is thought to be crucial to their early growth and survival. We examined stomach contents of larval bluegill Lepomis macrochirus and yellow perch Perca flavescens in Pelican Lake and Cameron Lake, Nebraska, in 2004 and 2005. We also determined zooplankton availability and calculated prey selection using Chesson’s a. In addition, we investigated potential match–mismatch regulation of recruitment from 2004 to 2008. Bluegill positively selected copepod nauplii and Bosmina spp., and yellow perch often selected copepods. Abundant zooplankton populations were available for …

Comparisons Of Fish Species Inside And Outside Of Marine Protected Areas Off The South Central Coast Of California, David E. Rasmussen

Master's Theses

COMPARISONS OF FISH SPECIES INSIDE AND OUTSIDE OF MARINE PROTECTED AREAS OFF THE SOUTH CENTRAL COAST OF CALIFORNIA

David E. Rasmussen

From 2004-2008 and 2008-2009 Cal Poly University researchers conducted two separate tag and recapture studies of nearshore fish populations along California’s central coast. Three locations were sampled that have experienced different degrees of fishing pressure. Big Creek MPA has been closed to all fishing from 1993 onwards and is the farthest from port of all locations. Cambria lies closest to port of the three locations and because of this has the highest fishing pressure. Piedras Blancas lies midway between …

Evaluation Of The Recreational Marron Fishery Against Environmental Change And Human Interaction: Final Frdc Report – Project No. 2003/027, Martin De Graaf, Stephen Beatty, Brett M. Molony

Fisheries Research Reports

The distribution of marron in the southwest of Australia has seen many changes since European settlement. Reconstructions of their range from historical records suggested that marron inhabited the waters between the Harvey River and Denmark River. Due to translocation, their range has expanded as far north as the Hutt River and as far east as Esperance. Although at present marron still exist in all the original rivers within the southwest, their distribution within these rivers has contracted. Poor water quality, salinity, low rainfall and environmental degradation in the upper and lower reaches have restricted marron populations.

North Coast Fish Identification Guide, Ben M. Rome, Stephen J. Newman

Fisheries Occasional Publications

The intention of the North Coast Fish Identification Guide is to provide a simple, easy to use manual to assist commercial, recreational, charter and customary fishers to identify the most commonly caught marine finfish species in the North Coast Bioregion, Western Australia. This guide is not intended to be a comprehensive taxonomic fish ID guide for all species. It is anticipated that this guide will assist fishers in providing a more comprehensive species level description of their catch and hence assist scientists and managers in understanding any variation in the species composition of catches over both spatial and temporal scales.

Identification Of Causative Fish For A Food Poisioning In Taiwan By Using Sds-Page Technique, Tai-Yuan Chen, Nan-Hong Chen, Wen-Feng Lin, Ken-Lin Hwang, Yun-Chieh Huang, Deng-Fwu Hwang

Journal of Marine Science and Technology–Taiwan

A food poisoning incident has occurred due to ingestion of red grouper meat on February 2006 in southern Taiwan. Two patients showed diarrhea, muscle weakness, vertigo and severe muscle pain. The 2 pieces of causative residues were investigated by toxicity assay. In order to identify the fish species of causative samples, sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) technique was applied in this study. According to the low molecular weight region (＜30.0 kD) of species-specific patterns extracted from both myofibrillar and sarcoplasmic proteins, two poisoning samples were identified as Lutjanus bohar. L. bohar is a notorious grouper species with ciguatera in …

Application Of Acoustic Telemetry To Assess Residency And Movements Of Rockfish And Lingcod At Created And Natural Habitats In Prince William Sound, Brad F. Reynolds, Sean P. Powers, Mary Anne Bishop

University Faculty and Staff Publications

Loss and/or degradation of nearshore habitats have led to increased efforts to restore or enhance many of these habitats, particularly those that are deemed essential for marine fishes. Copper rockfish (Sebastes caurinus) and lingcod (Ophiodon enlongatus) are dominant members of the typical reef fish community that inhabit rocky and high-relief substrates along the Pacific Northwest. We used acoustic telemetry to document their residency and movements in the nearshore waters of Prince William Sound, Alaska in order to assess use of created reef habitat in an individual-based manner. A total of 57 fish were surgically implanted with …

Environment-Induced Phenotypic Plasticity In The Teeth Of Hatchery And Wild Largemouth Bass, Micropterus Floridanus, Tamilselvi Selvaraj

Masters Theses & Specialist Projects

Successful stock enhancement of hatchery-reared fish depends heavily on the release of individuals able to demonstrate strong survival skills. Overall survival of fishes is a reflection of a successful blend of physiology, anatomy, and behavior. With fishes being highly phenotypically plastic, the potential exists for all aspects of hatcheryreared fish to vary significantly from their wild counterparts while having potentially adverse effects on their survival after release. Previous analyses have demonstrated significant differences between the feeding behavior of hatchery-reared and wild caught largemouth bass (Micropterus floridanus) in the laboratory, as well as differences in the development of the …

Review Of The Exploitation Of Marine Resources Of The Australian Indian Ocean Territories: The Implications Of Biogeographic Isolation For Tropical Island Fisheries, Matthew Hourston

Fisheries Research Reports

The small islands of the Indian Ocean Territories are isolated reefs in an expanse of open ocean of abyssal depth. The majority of marine species that live on their reefs and lagoons have settled there from remote locations. Colonising individuals are presumed to have come to the island as the result of unusual weather and current conditions and form populations that are, necessarily, largely self-sustaining. The isolated populations that make up many of the fish and invertebrate stocks at the Cocos (Keeling) and Christmas Islands rely almost exclusively on larvae returning to their home reef to settle, grow and ultimately …

The Effects Of Growth Hormone In The Inner Ear Of Zebrafish (Danio Rerio) During Hair Cell Regeneration, Chia-Hui Lin

Masters Theses & Specialist Projects

Although deafness is a universal problem, effective treatments have remained elusive. In order to develop potential treatments, an overall understanding of the cellular process of auditory hair cell regeneration, which occurs in fish but not mammals, must be established. A previous microarray analysis and qRT-PCR validation of noise-exposed zebrafish showed that growth hormone (GH) was significantly upregulated during the process of auditory hair cell regeneration. Thus, GH may play an important role during hair cell regeneration. However, cellular effects of exogenous GH in the zebrafish auditory hair cell regeneration have not been examined after noise exposure. To understand the effect …

O’Dowd, C., Mothersill, C.E., Cairns, M.T., Austin, B., Lyng, F.M., McClean, B. and Murphy, J.E.J. Assessing the mitochondrion as a biomarker of fish tissue damage using g radiation as a stress model in vitro.

There is an ever-increasing need for biomarkers to identify toxic stress in the aquatic environment. Such techniques need to be accurate, expeditious, ethical and economical. Typically, in vitro based platforms fit these criteria however many of these systems often undergo ‘assay drift’ and consequently do not fully represent the real-life situation.

In recent years, there has been growing interest in the mitochondrion and its (dys)function …

Coastal And Marine Resource Condition Monitoring – Scoping Project: Final Nrm Report – Project 073007, Brett A. Human

Fisheries Research Reports

The marine and coastal environment of the Pilbara and Kimberley region in north-western Western Australia contains many assets, including remote and near pristine habitats, unique habitats within Australia, unique fauna and flora; as well as assets of value to commercial and industrial ventures; and for recreational human usage. However, there is a lack of monitoring in the Pilbara and Kimberley marine and coastal environments. This is in large part due to the remoteness of the area, making access difficult, and consequently making monitoring programs expensive to run in the region.
