Seagrass–Pathogen Interactions: ‘Pseudo-Induction’ Of Turtlegrass Phenolics Near Wasting Disease Lesions, Latina Steele, Melanie Caldwell, Anne Boettcher, Tom Arnold
Biology Faculty Publications
Marine protists of the genus Labyrinthula cause the seagrass wasting disease, which is associated with regional die-offs of eelgrass Zostera marina and also infects turtlegrass Thalassia testudinum . The ability of seagrasses to resist pathogen attack is determined by multiple factors, which are poorly understood. One factor hypothesized to influence seagrass disease resistance is the presence of (poly)phenolic natural products such as caffeic acid, which inhibits the growth of L. zosterae in in vitro laboratory bioassays. This hypothesis has been supported by reports of pathogen-induced phenolic accumulations in eelgrass Z. marina. To test the response of T. testudinum to …

Proposals For Community Discussion : A Quality Future For The Recreational Marron Fishery : A Five-Year Draft Strategy To Ensure The Long-Term Sustainability Of The Marron Fishery, Recreational Freshwater Fisheries Stakeholder Sub-Committee
Fisheries management papers
While some of the factors threatening the future of the marron fishery can be managed via traditional fisheries controls, many fall outside of the Department of Fisheries’ jurisdiction and require a ‘whole of Government’ approach to management. To help ensure a quality future for the recreational marron fishery, the Recreational Freshwater Fisheries Stakeholder Sub-committee (RFFSS) has now developed a set of draft management proposals designed to form the basis of a five-year management plan for the fishery.

A Five Year Management Strategy For Recreational Fishing On The South Coast. The Minister For Fisheries' Decision In Response To The Final Report Of The South Coast Recreational Fishing Working Group., Jon Ford (Minister For Fisheries; The Kimberley, Pilbara And Gascoyne)
Fisheries management papers
After careful consideration of the South Coast Recreational Fishing Working Group’s recommendations and the wide range of issues raised in submissions, I have made my decisions in respect to the future management arrangements for recreational fishing in South Coast Region. I believe the new management arrangements which will be implemented in 1 January 2006 will go a long way to protecting recreational fishing quality and meeting the long term needs for the sustainable management of recreational fishing. I did note that some of the most pressing concerns raised during public meetings, and in submissions, related to the interaction between the …

The Reef Fish Assemblage Of The Outer Los Angeles Federal Breakwater, 2002–2003, John Froeschke, Larry Allen, Daniel Pondella
The Reef Fish Assemblage Of The Outer Los Angeles Federal Breakwater, 2002–2003, John Froeschke, Larry Allen, Daniel Pondella
Daniel Pondella
The conspicuous and cryptic fish assemblage of the Los Angeles Federal Breakwater was assessed from 2002 to 2003. Thirty-five species were observed or collected during the study period. The assemblage of cryptic fishes was composed primarily of a mix of Oregonian and San Diegan, species including snubnose sculpin (Orthonopias triacis), coralline sculpin (Artedius corallinus) and blackeye goby (Rhinogobiops nicholsii). The species composition of conspicuous fishes was approximately equal between taxa from these two provinces. Blacksmith (Chromis punctipinnis), black perch (Embiotoca jacksoni) and kelp bass (Paralabrax clathratus) dominated the assemblage of conspicuous fishes. Species composition reflects the localized cool temperature regime …

The development of this strategy represents a significant step in protecting recreational fishing quality in the South Coast Region and meeting the long-term needs for the sustainable management of recreational fishing. All recommendations contained in this report were made only after careful consideration of the submissions and issues which were raised at public meetings, along with the action needed to be taken to protect the long-term sustainability of our fish stocks.
Recruitment In Degraded Marine Habitats: A Spatially Explicit, Individual-Based Model For Spiny Lobster, Mark J. Butler Iv, Thomas W. Dolan Iii, John H. Hunt, Kenneth A. Rose, William F. Herrnkind
Recruitment In Degraded Marine Habitats: A Spatially Explicit, Individual-Based Model For Spiny Lobster, Mark J. Butler Iv, Thomas W. Dolan Iii, John H. Hunt, Kenneth A. Rose, William F. Herrnkind
Biological Sciences Faculty Publications
Coastal habitats that serve as nursery grounds for numerous marine species are badly degraded, yet the traditional means of modeling populations of exploited marine species handle spatiotemporal changes in habitat characteristics and life history dynamics poorly, if at all. To explore how nursery habitat degradation impacts recruitment of a mobile, benthic species, we developed a spatially explicit, individual-based model that describes the recruitment of Caribbean spiny lobster (Panulirus argus) in the Florida Keys, where a cascade of environmental disturbances has reconfigured nursery habitat structure. In recent years, the region has experienced a series of linked perturbations, among them, seagrass die-offs, …

Feeding Behavior And Conditioning In Two Heterotrophic Dinoflagellates, Todd A. Egerton
Feeding Behavior And Conditioning In Two Heterotrophic Dinoflagellates, Todd A. Egerton
Biological Sciences Theses & Dissertations
Growth and abundance of heterotrophic dinoflagellate predators are generally attributed to the availability of algal prey. Several species of dinoflagellates feed on a wide variety of food types including fish. However the actual feeding preferences of dinoflagellates have been much less studied. In the few studies that have been carried out on dinoflagellate feeding preference, none have looked at possible factors that may affect preference. I conducted three experiments on the toxic dinoflagellate Pfiesteria piscicida and the related unnamed species Cryptoperidiniopsis brodyi which, (1) calculated the feeding preferences between algal Rhodomonas prey and fish blood cells and identified factors that …
Morphological And Molecular Defects In Zebrafish Embryos (Danio Rerio) After Chromated Copper Arsenate Exposure, Kerry Jean Lee
Morphological And Molecular Defects In Zebrafish Embryos (Danio Rerio) After Chromated Copper Arsenate Exposure, Kerry Jean Lee
Biological Sciences Theses & Dissertations
This investigation identified the morphological defects caused by different concentrations of chromium, copper, and arsenic (CCA) on the developing zebrafish embryo; in addition to defects caused by the three combined components (complete CCA). A change in the DNA of the developing embryos in response to the three components of CCA and complete CCA was also determined. Early Dania rerio embryos were cultured for five days with various concentrations of CCA components and complete CCA. Morphological defects were assessed with light microscopy and DNA fragmentation was determined by agarose gel electrophoresis. Embryonic exposure of D. rerio to sub lethal concentrations of …

A Sustainable Future For Recreational Fishing In The Cocos (Keeling) Islands. Proposal For Discussion., Department Of Fisheries.
Fisheries management papers
Fishing activity on the Cocos is essentially unmanaged at present and there has been some condern by the local community that a number of species, such as coral trout, have declined in numbers over the last decade. This draft strategy was developed by the Western Australian Department of Fisheries who now has responsibility for managing recreational fishing on behalf of the Commonwealth Department of Transport and Regional Services.

Access And Allocation Arrangements For The Commercial 'Wetline' Fisheries. Proposals For Discussion., Commercial Access Panel
Access And Allocation Arrangements For The Commercial 'Wetline' Fisheries. Proposals For Discussion., Commercial Access Panel
Fisheries management papers
The Minister for Fisheries established this review of open access (wetline) commercial fishery arrangements to provide a more effective management framework for wetline fishing and to complement the recreational initiatives. This must involve the removal of excess fishing capacity, including latent effort, from the fishery and the establishment of a dedicated commercial fishery with clear entry criteria and an appropriate limit on catch in each bioregion. However it must be made clear that the ‘wetline review’ is not a sectoral resource sharing exercise. Following the implementation of new management arrangements for the ‘wetline’ fisheries, the appropriateness of the existing levels …

Proposed Management Arrangements For The West Coast Commercial 'Wetline' Fishery. A Discussion Paper., West Coast And Gascoyne Management Planning Panel
Fisheries management papers
The ‘Wetline Review’ was established to implement an effective management framework for the commercial sector to complement the recreational initiatives. It must be stressed at the outset that this review is focussed on the take of scalefish by the commercial sector. The levels of use between the various user groups in the West Coast region will be examined under the new integrated fisheries initiative following the implementation of new management arrangements for scalefish taken by the commercial sector.
Benthic Fisheries Ecology In A Changing Environment: Unraveling Process To Achieve Prediction, Mark J. Butler Iv
Benthic Fisheries Ecology In A Changing Environment: Unraveling Process To Achieve Prediction, Mark J. Butler Iv
Biological Sciences Faculty Publications
Marine fisheries and the ecosystems that sustain them are increasingly beset by environmental deterioration, and the problem is particularly acute in coastal zones where human Populations are increasing. In the best of circumstances, fishery managers are faced with the multiple, often conflicting, demands of resource users, politicians, and scientists when considering strategies for resource management. A further challenge is that management decisions must be made against a backdrop of a deteriorating environment and the shifting status of coastal ecosystem integrity. Traditional tools for single-species management may be inadequate in these settings. Furthermore. the necessary empirical data to appropriately parameterize models …
