AquaNISInformation system on aquatic non-indigenous and cryptogenic species |
Species | Oncorhynchus mykiss | |
Date of the first record (?) | 1895 References (not structured): Welcomme RL (1988) International introductions of inland aquatic species. FAO Fisheries Technical Paper 294. 318 pp. Moriarty C, Fitzmaurice P (2000) Origin and diversity of freshwater fish in Ireland. Verhandlungen international Vereinigung fur Theoretische und Angewandte Limnologie 27: 128-130. Comments: Welcomme suggests that the introductions to Ireland were in 1900 to 1910. In Britain in 1884 eyed-eggs were introduced from the United States. All indications are that the date of introduction to Ireland is most likely to be 1895. |
Recipient region (?) | Country: Ireland LME: 24. Celtic-Biscay Shelf LME sub-region: Celtic seas References (not structured): Moriarty C, Fitzmaurice P (2000) Origin and diversity of freshwater fish in Ireland. Verhandlungen international Vereinigung fur Theoretische und Angewandte Limnologie 27: 128-130. Comments: Now widely distributed inland and cultivated at some sites about the coast such as Clew Bay |

Source region (?) | Not entered References (not structured): Welcomme RL (1988) International introductions of inland aquatic species. FAO Fisheries Technical Paper 294. 318 pp. Comments: Welcomme suggests that the introductions were in 1900 to 1910 with imports from the USA and England. |
Pathway / Vector (?) | Level of certainty: Direct evidence Pathway: Culture activities Vector: Regional stock movement References (not structured): Welcomme RL (1988) International introductions of inland aquatic species. FAO Fisheries Technical Paper 294. 318 pp. Comments: Eyed-eggs were imported and reared in hatchery raceways. |

Population status (?) | Established (Low level of certainty) References (not structured): Fahy E (1983) Feeding ecology of feral rainbow trout Salmo gairdneri Richardson in Mulroy Bay, an Atlantic Sea lough. Irish Naturalists' Journal 21(3): 103-107. Comments: Localised establishment but the majority of lakes/ponds are stocked with rainbow trout for a 'put-and-take' fishery also farmed in freshwater and cages in the sea. Some of the rainbow trout are escapees found in the wild. |

Species status (?) | Non-indigenous species References (not structured): MacCrimmon HR (1971) World Distribution of rainbow trout (Salmo gairdneri). - Journal of Fisheries Research Board of Canada 28, 663-704. Comments: Probably the most widely distributed fish in the world. Originating in the eastern North Pacific ranging from Alaska to the northern coast of Mexico. |
