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 …

In Vitro Enabling Technologies For Use In The Aquatic Environment, Colm J. O'Dowd

Doctoral

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.

A Bycatch Action Plan For The Pilbara Fish Trawl Interim Managed Fishery., Department Of Fisheries Western Australia

Fisheries Management Papers

The effect of commercial fishing on bycatch species and the marine ecosystem generally, has emerged as a significant national and international issue. Environmental issues associated with bycatch – including impacts on the ecology of non-target species of fish and wildlife – are important issues to address in reducing the impacts, or potential impacts, of commercial fisheries.

In 1998, the National Standing Committee on Fisheries and Aquaculture developed a national policy on fisheries bycatch. In 1999, the (then) State Minister for Fisheries adopted the national policy as his position on bycatch for Western Australia. The main objective of the policy is …
