(Galway-Mayo Institute of Technology, 2011)The current study presents data on age and growth for plaice (Pleuronectes platessa L.) sampled between November 2003 and February 2005 in ICES areas Via (northwest coast of Ireland), Vila (Irish Sea), Vllg (Celtic Sea), ... -
Age, growth and reproductive biology of whiting Merlangius merlangus (Linnaeus 1758) in the Celtic Sea
(Galway-Mayo Institute of Technology, 2003)Age, growth and reproductive biology were investigated for whiting (Merlangius merlangus) captured from the Celtic Sea (ICES division Vllg), for the period January 2001 to January 2002. Females dominated the sex ratio of ... -
Age, growth, reproductive biology and population dynamics of the common megrim Lepidorhombus whiffiagottis (Walbaum, 1792) from off the west coast of Ireland
(Galway-Mayo Institute of Technology, 2004)A total of 4,964 common megrim Lepidorhombus whiffiagonis, were examined from commercial catches in Divisions VII b^, off the west coast of Ireland, between April 1997 and February 2001. A sex ratio of 31.8:1 females to ... -
An assessment of biological and population parameters of the Common whelk, Buccinum undatum (L.) in the region of the North West Irish whelk fishery
(Galway-Mayo Institute of Technology, 2006)The Common whelk, Buccinum undatum (L.) is a conspicuous benthic scavenger in Irish waters, and is a valuable fisheries resource in South East Ireland. B. undatum is fished in many parts of its range, and previous studies ... -
Atlantic herring (Clupea harengus) in the Irish and Celtic Seas; tracing populations of the past and present
(Galway-Mayo Institute of Technology, 2008)Several herring stocks are found around Ireland, of which the Irish and Celtic Seas are two. Herring in the Irish Sea spawn in autumn and in the Celtic Sea spawning takes place in autumn and winter. During the first year ... -
Breeding biology of the Common Swift (Apus apus) in Ireland – the most north-westerly edge of the nesting habitat
(2022-01)Ireland is at the north-western edge of the Common Swifts’ (Apus apus) range, and information on the basic breeding parameters of the species in this region is sparse. Therefore, the main objective of this research was to ... -
Cloning, Expression and Purification of β-Defensins from S. salar (Atlantic Salmon)
(Galway- Mayo Institute of Technology, Ireland, 2018-07)Introduction: The purpose of this study was to develop a method to recombinantly produce salmon β-defensins in the prokaryotic host Escherichia coli. β-defensins are a group of antimicrobial peptides (AMPs) which display ... -
Data for the sustainable management of an emerging fishery: Age, growth and stock structure of Atlantic saury Scomberesox saurus saurus (Walbaum), in the Northeastern Atlantic Ocean
(Galway-Mayo Institute of Technology, 2011)Almost half of Ireland’s commercial stocks face overexploitation. As traditional species decrease in abundance and become less profitable, the industry is increasingly turning to alternate species. Atlantic saury (Scomberesox ... -
Defining habitat characteristics influencing the distribution, density and growth of Plaice (Pleuronectes Platessa) and Dab (Limanda Limanda) on west of Ireland nursery grounds
(Galway-Mayo Institute of Technology, 2012)Plaice (Pleuronectes platessa, L.) and dab (Limanda limanda, L.) are among the most abundant flatfishes in the north-eastern Atlantic region and the dominant species in shallow coastal nursery grounds. With increasing ... -
Determination of selenium in selenium enriched yeast.
(Galway-Mayo Institute of Technology, 1999)Selenium, although a rare mineral, is widely distributed in minute amounts in virtually all materials of the earth’s crust, its average abundance is approximately ~0.09ppm. Selenium is rarely found in its native state i.e. ... -
Development of lab-simulated slow pyrolysis and generation of pyrolysis profiles of common hydrocarbon polymers for fire debris analysis
(Atlantic Technological University, 2023-07)This study aimed to investigate the pyrolysis behaviour of substrates and the influence of various factors on the formation of degradation products through experimental and real world simulations. Experimental simulation ... -
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
