Addressing cohort uncertainty through advanced length frequency and stage-based assessment models with application to anglerfish
(Atlantic Technological University, 2022-02)Fisheries stock assessments are important tools for successful management of fisheries. Reliability of a stock assessment model is often determined by the data available and accounting for key uncertainties in the data is ... -
Biology and ecology of flatfish species on west of Ireland nursery grounds
(Galway-Mayo Institute of Technology, 2011)Commercial flatfish captured in demersal fisheries along the west coast of Ireland include quota species such as plaice (Pleuronectes platessa L), in addition to high value non-quota species, turbot (Psetta maxima L.) and ... -
Driven to distraction? Behavioural impacts of anthropogenic noise on the European hermit crab (Pagurus bernhardus) from individual to group level
(Galway-Mayo Institute of Technology, 2019-05)Human activities are altering the planet at an unprecedented scale and pace, ranging from effects on global systems such as climate and carbon cycles to localised but globally wide-spread exposure to anthropogenic pollution ... -
Food production for juvenile seahorse culture
(Galway-Mayo Institute of Technology, 2004)The aim of this project was to find a reliable, cost effective food for production of Hippocampus spp. juveniles. The first feeding preferences in terms o f short term survival and growth were investigated. H. guttulatus ... -
Gill disease in finfish aquaculture with emphasis on amoebic gill disease
(Galway-Mayo Institute of Technology, 2017-08)Gill disease is one of the most significant challenges facing global salmon aquaculture and in terms of economic impact; amoebic gill disease (AGD) caused by the free living protozoan Neoparamoeba perurans is perhaps the ... -
Informing improved management of mixed fisheries through comparative modelling of fleet dynamics
(2020-09)Mixed fisheries, where several species are caught in the same fishing operation, are ubiquitous and a major challenge for fisheries management. Overexploitation occurs in mixed fisheries where fishers catch species for ... -
Interactions between seabirds and pollution in Irish waters
(Galway-Mayo Institute of Technology, 2017-01)Seabirds are abundant and ubiquitous globally. They suffer pressure from many contemporary threats such as fisheries, invasive species and pollution. This thesis focuses on two different types of pollution: plastic litter ... -
An investigation into the effects of environmental variables on the early life history stages of fish, with special emphasis on the flatfish of the west of Ireland
(Galway-Mayo Institute of Technology, 2012-10)The temperate waters of the North-east Atlantic host a diverse marine ecosystem, and within that ecosystem fish are a valuable resource both in terms of ecosystem functioning and commercial exploitation. The West Coast of ... -
Life history, behaviour and social structure of bottlenose dolphins (Tursiops truncatus) in the Shannon Estuary, Ireland
(Galway-Mayo Institute of Technology, 2017-11)Bottlenose dolphins are a complex intelligent species with great diversity and variability in behaviours and social systems across populations, but site-specific information on many aspects of the bottlenose dolphin ... -
Molecular ecology of white-clawed crayfish (Austropotamobius pallipes) in Ireland.
(Galway-Mayo Institute of Technology, 2018-10)The white-clawed crayfish (Austropotamobius pallipes, Lereboullet 1858) is a large freshwater invertebrate that has important functions in maintaining ecosystems. Historically, the species was broadly distributed across ... -
Optimising growth and survival in Irish aquaculture of abalone and sea urchins
(Galway-Mayo Institute of Technology, 2015-09)Increased demand for abalone and sea urchins globally has resulted in increased production of these commercially important invertebrates in aquaculture. Transfer of aquaculture technology from established producing countries ... -
Plaice on Irish and Scottish coasts: Contributions to the ecosystem-based management approach for pleuronectes platessa fisheries
(Galway-Mayo Institute of Technology, 2013-09)This study examines aspects of the early life history, growth and condition of plaice (Pleuronectes platessa) populations in Irish and Scottish waters, using innovative modelling approaches, among other techniques, to ... -
Power-to-Gas Energy Storage and its Effects on reducing Emissions and improving Energy Security for Ireland
(Galway- Mayo Institute of Technology, Ireland, 2012-09)The safeguarding of a reliable, environmental benign and economically meaningful energy supply is one of the key challenges Ireland is facing towards 2020 and beyond. The country is transforming its energy system from ... -
Scale Growth Analysis of Atlantic salmon (Salmo salar Linnaeus) Unlocking Environmental Histories
(Galway Mayo Institute of Technology, 2018-09)Atlantic salmon (Salmo salar L.) populations have declined rapidly in recent years across all geographical ranges with populations becoming extinct within certain areas. Direct observation of the salmon’s life is difficult ... -
Unlocking the archive: using the biochemical and isotopic composition of fish scales to understand the marine phase of Atlantic salmon
(2022-04)The Atlantic salmon is a species of great importance culturally, economically and ecologically. Recent declines suffered by many populations have been linked to marine mortality, therefore a better understanding of the ... -
Virulence factors associated with amoebic gill disease from Neoparamoeba perurans
(Galway-Mayo Institute of Technology, 2020-10)Determining the virulence factors associated with pathogenic organisms is imperative in comprehending disease pathogenesis and ultimately paves the way for methods of treatment and disease management. Neoparamoeba perurans ...
