Aquaculture with a Focus on Vietnam & Thailand
Nash, Róisín; Shibaev, Sergey; Petkam, Rakpong; TUNASIA; Erasmus+ (TUNASIA, 2021)The breadth of material this book covers includes wide range of issues related to aquaculture production, including its development history, farming systems and technology aspects, seed production, feed and feeding, health ... -
Current environmental microplastic levels do not alter emergence behaviour in the intertidal gastropod Littorina Littorea
Doyle, Darragh; Frias, João; Nash, Róisín; Gammell, Martin (2019)Microplastics (MPs) are an environmental pollutant of increasing concern. However, little research has assessed MP levels in intertidal gastropods. The authors explored MP abundance in the gastropod Littorina littorea from ... -
Low levels of microplastics recorded from the common periwinkle, Littorina littorea on the west coast of Ireland
Doyle, Darragh; Gammell, Martin; Frias, João; Griffin, Gráinne; Nash, Róisín (2019-12)Microplastics (MPs) are an environmental pollutant of increasing concern. However, little research has assessed MP levels in intertidal gastropods. The authors explored MP abundance in the gastropod Littorina littorea from ... -
Microplastics in brown trout (Salmo trutta Linnaeus, 1758) from an Irish riverine system
O'Connor, James D.; Murphy, Sinéad; Lally, Heather T.; O'Connor, Ian; Nash, Róisín; O'Sullivan, John; Bruen, Michael; Heerey, Linda; Koelmans, Albert A.; Cullagh, Alan; Cullagh, Declan; Mahon, Anne Marie (Elsevier B.V., 2020-09-01)Rivers play an important role in the overall transport of microplastic pollution (1 μm to 5 mm), with fluvial dynamics expected to influence biotic interactions, particularly for fish. So far, there have been few assessments ... -
Modelling the transfer and accumulation of microplastics in a riverine freshwater food web
O'Connor, James D.; Lally, Heather T.; Koelmans, Albert A.; Mahon, Anne Marie; O'Connor, Ian; Nash, Róisín; O'Sullivan, John J.; Bruen, Michael; Heerey, Linda; Murphy, Sinéad (Elsevier Ltd, 2022-02-26)Microplastics are a pervasive pollutant of aquatic ecosystems and are reported to interact with a wide range of aquatic biota. The complexities of natural food webs means that the transfer and accumulation of microplastics ... -
Morphometric methods for the analysis and classification of gastropods: a comparison using Littorina littorea
Doyle, Darragh; Gammell, Martin P.; Nash, Róisín (Oxford Academic, 2018)The study of morphology is a common means of biological grouping and classification. In recent years, morphometric studies have been dominated by quantitative geometric-morphometric methods of data extraction such as outline ... -
Perceptions About Marine Anthropogenic Litter & Microplastic Pollution in Ireland
Frias, João; Nash, Róisín (Irish Research Council, 2020)Thank you for your interest in this booklet which provides an insight into the current perceptions about marine litter and plastic pollution in Ireland. The results presented here are based on an online survey conducted ... -
Plastics, prawns, and patterns: Microplastic loadings in Nephrops norvegicus and surrounding habitat in the North East Atlantic
Joyce, Haleigh; Frias, João; Kavanagh, Fiona; Lynch, Rachel; Pagter, Elena; White, Jonathan; Nash, Róisín (Elsevier B.V., 2022-02-21)The presence of microplastics (MPs), a contaminant of emerging concern, has attracted increasing attention in commercially important seafood species such as Nephrops norvegicus. This species lend themselves well as ... -
Potential pathways, trophic transfer and bioindicators of microplastics in freshwater systems
O'Connor, James; Lally, Heather; Mahon, Anne Marie; O'Connor, Ian; Nash, Róisín; Jones, Noelle; Kelly, Mark; O'Sullivan, John; Bruen, Michael; Heerey, Linda; Koelmans, Albert; Murphy, Sinéad (2018-03)Microplastic (MP) polymers, 0.1 µm - 5 mm in size, are ubiquitous within aquatic environments. Due to their small size there is a risk that they may infiltrate and transfer within aquatic food webs. Though a limited number ... -
Quantification of microplastic ingestion by the decapod crustacean Nephrops norvegicus from Irish waters
Hara, Jenevieve; Frias, João; Nash, Róisín (Elsevier B.V., 2020-01-15)Microplastics are widespread pollutants in the marine environment, yet few studies have assessed the abundance and characteristics of microplastics in commercial species. This study evaluates the presence of ingested ... -
Size dependent egestion of polyester fibres in the Dublin Bay Prawn (Nephrops norvegicus)
Joyce, Haleigh; Nash, Róisín; Kavanagh, Fiona; Power, Thomas; White, Jonathan; Frias, João (Elsevier B.V., 2022-05-24)Microplastics (MPs) are an extensive global contaminant in the marine environment, known to be ingested by marine organisms. The presence of MPs in the commercially important marine decapod crustacean Nephrops norvegicus ...
