AquaNISInformation system on aquatic non-indigenous and cryptogenic species |
Species | Mytilus edulis [WoRMS] | |
Authority | Linnaeus, 1758 | |
Family | Mytilidae | |
Order | Mytilida | |
Class | Bivalvia | |
Phylum | Mollusca | |
Synonym (?) | ||
Sub-species level (?) | Not entered |
Native origin (?) | Ocean: Atlantic |
Life form / Life stage (?) |
Comments: From a fertilised egg cell the trochophora larva will develop, by a metamorphosis changing into a veliger larva. Those planktontic larval stages may be transported several hundred kilometres by sea currents. |
Sociability / Life stage (?) |

Reproductive frequency (?) | Iteroparous |
Reproductive type (?) | Sexual References: Figueras A (1989) Mussel culture in Spain and France. World Aquaculture, 20:8-17 Comments: Mussels have separate sexes – there are males and females. |
Developmental trait (?) | Spawning References: Figueras A (1989) Mussel culture in Spain and France. World Aquaculture, 20:8-17 Comments: In spring, each mussel female ejects about 5 to 12 millions of eggs into the water, where fertilisation by males of the environment will take place. |
Characteristic feeding method / Life stage (?) |
References (not structured): Bayne BL, Widdows J, Thompson RJ (1976) Physiology: II. In: Bayne BL, ed. Marine mussels, their ecology and physiology. Cambridge, UK: Cambridge University Press, 207-260 Comments: Mussels are suspension feeders, filtering particles of dissolved organic matter, detritus and phytoplankton from the water column. |
Mobility / Life stage (?) |
Comments: Until they have reached the size of 5 cm, those juvenile mussels may change their place several times, until they finally settle to a suitable piece of ground, preferably near other mussels. Millions of mussels hanging together with their byssus threads mark the development of a mussel bed. |
Salinity tolerance range (?) | Exact range: 4 - 40 References: Qiu, J. W., Tremblay, R., Bourget, E. 2002. Ontogenetic changes in hyposaline tolerance in the mussels Mytilus edulis and M. trossulus: implications for distribution. Marine Ecology Progress Series, 228, pp. 143-152. Comments: The adults of Mytilus edulis L. are euryhaline, but in the inner Baltic Sea at 4 to 5 ppt salinity they grow slowly and reach a small maximum size. The fertilization proceeded normally over a range of 15 to 40 ppt, and development to the trochophore stage occurred from 30 to 40 ppt. |
Habitat modifying ability potential (?) | Keystone species Comments: this species occupies a broad variety of microhabitats, expanding its zonational range from the high intertidal to subtidal regions and its salinity range from estuarine areas to fully oceanic seawaters. |
Toxicity / Life stage (?) | Not relevant |
Bioaccumulation association (?) | Anthropogenic chemical compounds Natural toxins References: Williams, D. E., Dawe, S. C., Kent, M. L., Andersen, R. J., Craig, M., & Holmes, C. F. (1997). Bioaccumulation and clearance of microcystins from salt water mussels, Mytilus edulis, and in vivo evidence for covalently bound microcystins in mussel tissues. Toxicon, 11(35), 1617-1625. Comments: Because they filter seawater, mussels tend to accumulate harmful substances, such as heavy metals, in their tissues. They therefore make good indicators of water quality and, in some areas, regular sampling takes place to monitor water quality. Common mussels are often used in aquaculture |
Known human health impact? | Known References: Grienke, U., Silke, J., Tasdemir, D. 2014. Bioactive compounds from marine mussels and their effects on human health. Food chemistry, 142, pp. 48-60. Comments: Mytilus is popular in human diet, providing high levels of proteins, omega-3 polyunsaturated fatty acids (PUFAs), iodine, and carbohydrates. |
Known economic impact? | Known References: Dankers, N., Zuidema, D. R. 1995. The role of the mussel (Mytilus edulis L.) and mussel culture in the Dutch Wadden Sea. Estuaries, 18(1), pp. 71-80. Loo, L. O., Rosenberg, R. 1983. Mytilus edulis culture: growth and production in western Sweden. Aquaculture, 35, pp. 137-150. Comments: M. edulis are being extensively cultured in open waters in The Strait of Georgia, British Columbia, where they are considered superior to the native M. trossulus, having higher meat yields, less fragile shells, and reduced likelihood of summer mortality. |
Known measurable environmental impact? | Known References: Hellou, J., Law, R. J. 2003. Stress on stress response of wild mussels, Mytilus edulis and Mytilus trossulus, as an indicator of ecosystem health. Environmental Pollution, 126(3), pp. 407-416. |
