A great deal of research and control work has been conducted on specific aquatic IAS threats in Ireland, some examples of which are presented below. Although the issues and solutions are country-specific, they are also of wider relevance to other countries around the world.

Chub ( _Leuciscus cephalus_ ) is a non-native fish species with the potential to become invasive in Irish rivers.3 One serious consequence of introducing chub into Irish rivers is the possibility of introducing pathogens to which native species have no resistance. Moreover, if populations of chub species were to become established, they could adversely effect indigenous fishes, including salmon ( _Salmo salar_ ) and brown trout ( _Salmo trutta_ ), via direct predation and competition for food and space. Chub were illegally introduced to the Inny River, a tributary of the Shannon River, by anglers in the early 2000s, and their presence was confirmed in 2005. Inland Fisheries Ireland commenced an eradication programme in 2006, employing electric fishing to physically remove chub from the river. This programme continued until 2014. All chub removed were euthanized. Between 2010 and 2014, electric fishing operations recovered no further chub, and anglers did not report any chub in the river. Therefore, it is presumed that the species has been successfully eradicated from this river.

Water primrose ( _Ludwigia grandiflora_ ) is a wetland and aquatic plant species that is highly invasive in the British Isles and mainland Europe. It was first reported in Ireland in 2009 in an ornamental pond. Subsequent investigations revealed its presence in other ponds in the vicinity. Inland Fisheries Ireland commenced a programme of herbicide control at all infested ponds in 2010 and this continued until 2012. Monitoring at all of the treated sites (and many others in the area) in 2013, 2014 and early 2015 revealed no specimens of water primrose.

In 2005, the first record of curly leaved waterweed ( _Lagarosiphon major_ ) in a natural lake (Lough Corrib, 18 000 ha) in Ireland was confirmed.4 _Lagarosiphon_ is a highly invasive submerged aquatic plant that rapidly overgrows suitable habitats and competitively excludes native biota. Inland Fisheries Ireland acquired EU funding, and a comprehensive research and management programme was put in place. By the end of this programme

 A great deal of inquiry and restraint work has been conducted on specific aquatic IAS threat in Ireland, some model of which are presented below. Although the issue and solutions are country - specific, they are besides of wide-eyed relevance to other country around the world. 

 Chub (_ Leuciscus cephalus _) is a non - native fish coinage with the potential to become invasive in Irish rivers.3 One serious consequence of introducing chub into Irish rivers is the possibility of introducing pathogen to which native species have no resistance. furthermore, if populations of chub species were to become established, they could adversely effect indigenous fishes, include salmon (_ Salmo salar _) and brown trout (_ Salmo trutta _), via direct predation and competition for food and space. Chub were illegally introduced to the Inny River, a feeder of the Shannon River, by anglers in the early 2000s, and their presence was confirmed in 2005. Inland Fisheries Ireland commenced an eradication programme in 2006, employing electric fishing to physically absent chub from the river. This programme continued until 2014. All chub removed were euthanized. Between 2010 and 2014, electric fishing operations recovered no further chub, and anglers did not report any chub in the river. Therefore, it is presumed that the species has been successfully eradicated from this river. 

 Water primrose (_ Ludwigia grandiflora _) is a wetland and aquatic plant coinage that is highly incursive in the British Isles and mainland Europe. It was first report in Ireland in 2009 in an cosmetic pond. Subsequent investigations revealed its presence in other ponds in the vicinity. Inland Fisheries Ireland commenced a programme of herbicide control at wholly infested ponds in 2010 and this continued until 2012. Monitoring at all of the treated sites (and many others in the area) in 2013, 2014 and early 2015 revealed no specimens of water primrose. 

 In 2005, the first record of curly leaved waterweed (_ Lagarosiphon major _) in a lifelike lake (Lough Corrib, 18 000 ha) in Ireland was confirmed.4 _ Lagarosiphon _ is a highly encroaching submerge aquatic plant that rapidly overgrows suitable habitats and competitively eject native biota.
