Distribution, seasonal occurrence, recruitment and growth of juvenile commercial flatfish species on the west coast of Ireland
(Galway-Mayo Institute of Technology, 2004)The population dynamics of juvenile flatfish were investigated on the west coast of Ireland. Firstly, beach seining was carried out to assess spatial and temporal variations in flatfish assemblages, on sandy beach nursery ... -
The drivers and dynamics of fisher behaviour In Irish fisheries
(Galway-Mayo Institute of Technology, 2013)It is widely acknowledged within the scientific community that a single species approach to European mixed fisheries can result in species-specific advice inconsistent with multi-species management objectives. Within the ... -
Effect of Freeze-chill Technology and Modified Packaging on the Quality of Whiting (Merlangius merlcmgus), Mackerel (Scomber scombrus) and Salmon (Salmo salar) Portions
(Galway-Mayo Institute of Technology, 2003)Freeze-chilling involves freezing and frozen storage followed by thawing and chilled storage. It offers logistic benefits for fish packers as it enables packaged fillets to be held frozen and then released into the chill ... -
Effects of selected post harvest processes on brown crab (Cancerpagurus L.) and European lobster (Homarus gammarus L.) from Irish Crustacean Fisheries
(Galway-Mayo Institute of Technology, 2010)The crustacean fishery is important to the socio economics of rural and island communities around Ireland; with brown crab (Cancer pagurus) and European lobster (.Homarus gammarus) being the most valuable shellfish species. ... -
An emergent pathogen, phytophthora ramorum, in Irish woodlands
(Galway-Mayo Institute of Technology, 2009)Phytophthora kemoviae and Phytophthora ramorum are both recently discovered pathogens of tree species. The disease that causes P. ramorum has been given the common name of Sudden Oak Death, in the US, because the expression ... -
Estimating fish stock population parameters from bottom trawl surveys: sources and magnitude of uncertainty
(Galway-Mayo Institute of Technology, 2006)Fisheries surveys are widely used in the stock assessment process by providing time series of relative abundance and recruitment strength. Surveys also provide biological data that have the potential to improve stock ... -
Evaluation of fish pots as a feasible fishing method in Irish waters, with specific reference to the physiological effects of common and alternate pots on the lesser spotted dogfish (Scyliorhinus canicula).
(Galway-Mayo Institute of Technology, 2009)Finfish pots have emerged as a “responsible” gear, when used in combination with conservational and technical measures to sustain fisheries. Previous trials in Irish waters have offered no published reported data and so ... -
Extreme galaxies: TeV gamma-ray emission from the Blazar 1ES 2344+514
(Galway-Mayo Institute of Technology, 2005)This thesis describes an investigation of Very High Energy (VHE) gamma-ray emission from the blazar galaxy 1ES 2344+514, based on data from five observational seasons (1999-2004) using the Whipple 10-metre telescope in ... -
Field enhancement of the parasitoid bracon hylobii (Hymenoptera: Braconidae) to control hylobius abietis (Coleoptera: Curculionidae); the large pine weevil
(Galway-Mayo Institute of Technology, 2012)Hylobius abietis (Coleoptera: Curculionidae), the large pine weevil is the most damaging pest of reforestation sites in Ireland. This study examined the possibility of manipulating populations of a species specific parasitoid, ... -
A framework for high availability and optimum system performance in an Application Service Provider (ASP) environment
(Galway-Mayo Institute of Technology, 2006-06)The Application Service Provision (ASP) model offers access to centrally managed and hosted applications, via the Internet, on a subscription / rental basis. From its inception in the late 1990s, many have heralded the ASP ... -
Genetic variability and phylogeography of the invasive zebra mussel, dreissena polymorpha (PALLAS)
(Galway-Mayo Institute of Technology, 2005)The zebra mussel, Dreissena polymorpha (Pallas), a bivalve species originally native to the Black and Caspian seas, has invaded Ireland in the last decade. Five microsatellite loci were used to investigate genetic diversity ... -
A holistic stock analysis of Albacore tuna (Thunnus alalunga) from the North Atlantic Ocean and Mediterranean Sea
(Galway-Mayo Institute of Technology, 2009)Albacore tuna (Thunnus alalunga, Bonnaterre, 1788) is a highly migratory scombrid with a cosmopolitan distribution inhabiting all the worlds’ ocean, in both tropical and temperate regions. Albacore juveniles and adults are ... -
Impacts of the parasitic dinoflagellate Hematodinium sp. on Irish crustacean fisheries
(Galway-Mayo Institute of Technology, 2010)Infection of Cancer pagurus by a parasitic dinoflagellate of the genus Hematodinium is described for the first time in Ireland. An industry-based monitoring programme was established to determine seasonality of infection ... -
The inshore distribution and abundance of small cetaceans on the West Coast of Ireland: site assessment for SAC designation and an evaluation of monitoring techniques
(Galway-Mayo Institute of Technology, 2009)To date, 24 cetacean species have been recorded in Irish waters. These are protected by a range of legislation, including the Whale Fisheries Act, the Wildlife Acts and the EU Habitats Directive, which oblige Ireland to ... -
Instrumentation and software for the VERITAS Project and the detection of TeV Gamma-Ray Emission from the BL Lacertae Object 1ES1959+650
(Galway-Mayo Institute of Technology, 2003)Transmission of Cherenkov light through the atmosphere is strongly influenced by the optical clarity of the atmosphere and the prevailing weather conditions. The performance of telescopes measuring this light is therefore ... -
An investigation into system security requirements and implementation in an Application Service Provider (ASP) environment
(Galway-Mayo Institute of Technology, 2006)Although the ASP model has been around for over a decade, it has not achieved the expected high level of market uptake. This research project examines the past and present state of ASP adoption and identifies security as ... -
An investigation into the detection and identification of OsHV-1 μvar virus and associated risk factors causing mortalities in Crassostrea gigas in Ireland.
