AquaNISInformation system on aquatic non-indigenous and cryptogenic species |
Species | Mytilicola intestinalis | |
Date of the first record (?) | 1947 References (not structured): Grainger JNR (1951) Notes on the biology of the copepod Mytilicola intestinalis Steuer. Parasitology 41 (3/4): 135-142. Comments: The first record was November 1947. |
Recipient region (?) | Country: Ireland LME: 24. Celtic-Biscay Shelf LME sub-region: Celtic seas References (not structured): Grainger JNR (1951) Notes on the biology of the copepod Mytilicola intestinalis Steuer. Parasitology 41 (3/4): 135-142. Comments: First recorded from Cork Harbour from Church Bay in the Harbour Entrance. |
|
Source region (?) | Unknown References (not structured): Grainger JNR (1951) Notes on the biology of the copepod Mytilicola intestinalis Steuer. Parasitology 41 (3/4): 135-142. Comments: Unclear where the source of the population was. |
Pathway / Vector (?) | Level of certainty: Possible Pathway: Vessels Vector: Sea chest Vector: Ship’s hull References (not structured): Grainger JNR (1951) Notes on the biology of the copepod Mytilicola intestinalis Steuer. Parasitology 41 (3/4): 135-142. Comments: Might have been introduced as parasites within the mussel Mytilus edulis fouling vessel hulls. There is adequate evidence that this mussel is frequently found on leisure craft and ship hulls. |
Habitat type (?) | Aquaculture sites Estuary Marina Sheltered coastal area References (not structured): Crowley M (1972) The parasitology of Irish mussels. Department of Agriculture and Fisheries, Fishery leaflet No 35, 12pp. |

Wave exposure (?) | Not entered | |
Salinity range (?) | Not entered | |
Temperature range (?) | Not entered |
Zonation / Substratum (?) | Benthic and Pelagic: Littoral (Benthic) Littoral (Pelagic) Sublittoral within photic zone References (not structured): Davey JT (1989) Mytilicola intestinalis (Copepoda: Cyclopoida): a ten year survey of infested mussels in a Cornish estuary, 1978-1988. Journal of the Marine Biological Association of the United Kingdom 69: 823-836. Gee JM, Davey JT (1986) Stages in the life history of Mytilicola intestinalis Steuer, a copepod parasite of Mytilus edulis (L.), and the effect of temperature on their rates of development. Journal du Conseil International pour l’Exploration de la Mer 42: 254-264. Comments: There is a free-living larval stage that subsequently infests the gut of the mussel Mytilus edulis. |
|
Reproductive duration (?) | Unknown Comments: According to Grainger (1951) Females with egg sacs were found at all times of the year but there were more with egg-cases during the summer. | |
Reproductive seasonality (?) | Not entered | |
Migration pattern (?) | Not entered |
Population status (?) | Common (Moderate level of certainty) References (not structured): Crowley M (1972) The parasitology of Irish mussels. Department of Agriculture and Fisheries, Fishery leaflet No 35, 12pp. Murray PJ (1972) The occurrence of Mytilicola intestinalis Steuer on the coasts of counties Galway and Clare. Irish Naturalists' Journal 17: 198-199. Comments: In 1948 it was recorded from four localities, two in Cork Harbour (Church Bay and Fountainstown), The River Bandon at Kinsale and at Kinvara in Galway Bay. A study at eighteen other sites in this year did not reveal any further specimens. It can often in some localities have almost 100% levels of infestation in mussels. Murray (1972) found it to remain confined to the Galway Bay region with high levels of prevalence in the innermost part of the bay. |

Species status (?) | Cryptogenic References (not structured): Minchin D (1996) Management of the introduction and transfers of marine molluscs. Aquatic Conservation, Marine and Freshwater Ecosystems, 6: 229-244. Grainger JNR (1951) Notes on the biology of the copepod Mytilicola intestinalis Steuer. Parasitology 41 (3/4): 135-142. Comments: Might have been spread from the Mediterranean Sea to northern Europe. This parasite occurs from The Adriatic, Mediterranean and North seas. |
