Effect of salinity on growth of mussels, Mytilus edulis, with special reference to Great Belt (Denmark). Collectively they occupy both coasts of the North Atlantic (including the Mediterranean) and of the North Pacific in temperate to polar waters, as well as coasts of similar nature in the Southern Hemisphere. (2003) found that at high velocities, larvae of Mytilus spp. Biogeosciences, 7 (11), 3879-3891. Hver underinddeling identificeres af en 8-cifret numerisk kode. NB: The resilience and the ability to recover from human-induced pressures is a combination of the environmental conditions of the site, the frequency (repeated disturbances versus a one-off event) and the intensity of the disturbance. Intertidal ecosystems are likely to be more negatively impacted than subtidal ecosystems, due to their increased daily and seasonal variations in temperatures (Jones et al., 2009). B.L. & Rosenberg, R., 1983. Essink (1999) suggested that deposition of sediment (mud or sand) on shallow mussel beds should be avoided. Blue mussel beds may be removed or damaged by static or mobile gears that are targeting other species. Sensitivity assessment Mytilus edulis beds have no avoidance mechanisms to escape targeted harvesting and as a result, a significant proportion of the bed can be removed (Palmer et al., 2007; Narvarte et al., 2011). Toxicants in the aqueous ecosystem. The low-intensity simulated bait-removal treatments had reduced percentage cover by 57.5% at the end of the 12 month experimental period. Open Journal of Marine Science, 2, 167-176, Riisgård, H.U., Lüskow, F., Pleissner, D., Lundgreen, K. & López, M., 2013. A number of invertebrate predators, particularly crabs and starfish, can be important in regulating Mytilus populations. Woodworth, P.L., Shaw, S.M. Hydrobiologia, 484 (1-3), 89-98. Where mussel beds occurred on pebble and sand substrata (mixed substrata) sediment erosion was lower than that of the 100% cover on the sandy substrata regardless of mussel density. Sensitivity assessment. Ibis, 146 (s1), 18-20. The effects of sea-level rise and increased wave action may be increased further due to storms and storm surges. Linking Thermal Tolerances and Biogeography: Mytilus edulis (L.) at its Southern Limit on the East Coast of the United States. Where the mussel beds occurred on sandy substratum the re-suspension rate was four and five times higher for areas with 25% and 50% mussel cover compared to bare sediment due to the increased turbulence and scouring around the mussels. Effects of human trampling on marine rocky shore communities. Marteiliosis in molluscs: a review. Mytilus edulis is a commercially targeted species worldwide and has been fished for hundreds of years and managed in England and Wales for the last hundred years (Holt et al., 1998). Crooks, S., 2004. Increased flow rate increases the risk of mussels being detached from the bed and transported elsewhere where their chance of survival will be significantly reduced due to the risk of predation and siltation (Dare, 1976). Available from: http://www.wfduk.org. Their upper limits are controlled by temperature and desiccation (Suchanek, 1978; Seed & Suchanek 1992; Holt et al., 1998) while the lower limits are set by predation, competition (Suchanek, 1978) and sand burial (Daly & Mathieson, 1977). Holt et al. Integrative and Comparative Biology, 50 (2), 213-225. Berthe et al. Genetic impact of aquaculture activities on native populations. Mytilus edulis has a wide distributional pattern, mainly due to its abilities to withstand wide fluctuations in salinity, desiccation, temperature, and oxygen tension. In addition, a change in sediment type would also change the biotope definition. Mytilus edulis beds on variable salinity infralittoral mixed sediment. Journal of Molluscan Studies, 65, 289-294. At another site, the mussel bed was composed of two layers, so that while mussels were lost, cover remained. The mussel Mytilus: ecology, physiology, genetics and culture. Cambridge University Press. FC 73-03-327], Marine Biological Association of the UK, Plymouth, 48 pp. However, at high densities (100% cover) the beds remained stable, with re-suspension being about 3 times lower than areas with  0% cover, due to the high number of byssal attachments between individuals (Widdows et al., 2002).

In addition, Holt et al., (1998) recorded an incident of the removal of an entire bed that is adjacent to a road in Anglesey due to fishermen bait collecting. We document successful settlement of wild mussel larvae ( Mytilus edulis ) in a periodically CO2-enriched habitat. Marine Ecology Progress Series, 37, 153-158. Intertidal Mytilus edulis beds are considered to express ‘Medium’ resistance to changes in emergence with mussels at the upper and lower limits exhibiting the greatest effects. Theede et al., (1969) reported LD50 of 35 days for Mytilus edulis exposed to 0.21 mg/l O2 at 10°C, which was reduced to 25 days with the addition of sulphide (50 mg/l Na2S.9H2O). resulting in heavier infections which can lead to mortality. The activities that penetrate the seabed could result in removal of part of a bed and its associated fauna and flora. In the Wadden Sea, where fishing had caused the destruction of the local population of Sabellaria spinulosa, Mytilus edulis was able to colonize, partly because of the increase in coastal eutrophication (Maddock, 2008). Widdows et al. The increased energy used for byssus production in the high flow environments may reduce the energy that is available for other biological activities (Alfaro, 2006). Long-term laboratory experiments on the influence of ferric hydroxide flakes on the filter-feeding behaviour, growth, iron content and mortality in Mytilus edulis L. Marine pollution and sea life. Foliose red seaweeds may also be present, but the species composition and their abundance vary between sites. Species such as Corallina officinalis occur widely. Marine Ecology Progress Series 305: 147-52. Available from: http://www.dardni.gov.uk/pacific-oysters-issue-paper.pdf. Mussel populations in Sullom Voe experienced moderate hydrocarbon pollution and a reduced SFG but had sufficient capacity to grow, reproduce and maintain a viable population (Widdows, A sunflower oil tanker spill off the Anglesey coast resulted in ingestion of oil droplets and subsequent mortalities after spawning (Mudge. Foliose red seaweeds may also be present, but the species composition … Most studies place its upper thermal limit at between 25-28°C for seawater temperatures and 30°C for air temperature, although these temperatures may lead to a decrease in growth. However, Koehn (1983) and Koehn & Hilbish (1987) reported a genetic basis to adaptation to salinity. However, after acclimation at 11°C for five days, the mussels maintained the high filtration rates down to 4°C. However, mortality will depend on the duration of smothering. The video shows two time lapse recordings of Mytilus edulis (Mytilus trossulus) filtration taken at the Nienhagen Riff (Rostock, Germany). Chesapeake Science, 10 (3), 227-233. Many individuals did not make it to the surface and were smothered by the accumulation of mussel-mud (Daly & Mathieson, 1977), so that whilst Mytilus edulis does have the capacity to vertically migrate through sediment some individuals will not survive. Brosnan & Crumrine (1994) observed little recovery of the congener Mytilus californianus in two years after trampling disturbance. In a laboratory experiment, Bourget (1983) showed that the median lethal temperature for 24 hours of exposure in Mytilus edulis was -16 °C for large mussels (>3 cm) and -12.5°C for juveniles (<1.5 cm). DOI https://doi.org/10.1371/journal.pone.0205908. Height on the shore generally determines lifespan, with mussels in the low shore only surviving between 2-3 years due to high predation levels whereas higher up on the shore a wider variety of age classes are found (Seed, 1969). 1118-1121. Bussell, J. Resilience is assessed as ‘Low’ (over 10 years) for all biotopes where resistance is assessed as ‘None’, as recovery is dependent on recruitment from other areas and recruitment can be sporadic. In addition, abrasion and sub-surface damage may attract mobile scavengers and predators including fish, crabs, and starfish to feed on exposed, dead and damaged individuals and discards (Kaiser & Spencer, 1994; Ramsay et al., 1998; Groenewold & Fonds, 2000; Bergmann et al., 2002). Hiebenthal, C., Philipp, E.E.R., Eisenhauer, A. At the upper range of a mussel’s tolerance limit, heat shock proteins are produced, indicating high stress levels (Jones et al., 2010). The mussels are often encrusted with the barnacles Semibalanus balanoides, Austrominius modestus or Balanus crenatus. Brosnan, D.M., 1993. Therefore, 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. and large blocks and boulders between 7–23 m depth. Mytilus edulis is a calcified organism but it is unlikely that this species will be significantly negatively impacted by ocean acidification, because acidification does not appear to lead to mortality, even at levels which far exceed levels of ocean acidification expected for the end of this century (e.g. At very low or negligible water flow, the effects of siltation may have adverse effects (see relevant pressure). Mussels were observed to close their shell valves in response to hypoxia and survived for 1-2 weeks before dying (Cole et al., 1999; Jorgensen, 1980). The non-linear interactions among these drivers can be context-specific and their effect on organisms in these habitats remains largely unknown, warranting further investigation. vol. It could not be concluded from this study whether the mortality was due to high temperatures, desiccation or a combination of the two. Mortality will be limited, and possibly avoided, where the smothering sediment is removed due to wave action or tidal streams, depending on how long the sediment remains over the individual mussels. For example, mussel reefs in the Wash, Morecambe Bay and the Wadden Sea are vulnerable to destruction by storms and tidal surges (Holt et al., 1998). But they also noted that even artisanal hand fisheries can deplete the mussel biomass on accessible beds in the absence of adequate recruitment of mussels. 62-69. Widdows et al. Mytilus edulis lives on the surface of the seabed held by byssus threads attached to either the substratum or to other mussels in the bed. (2010) noted that Mytilus edulis could absorb organic waste products from a salmon farm with great efficiency. tubes. Only 16% of buried mussels died after 16 days compared to almost 50% mortality at 32 days. Robledo, J.A.F., Santarem, M.M., Gonzalez, P. & Figueras, A., 1995. Marine Biology, 2, 325-337. For this, the Kiel Fjord (Western Baltic Sea) is a brackish (12–20 g kg −1) and CO 2 enriched habitat, but the blue mussel Mytilus edulis dominates the benthic community. Brosnan and Crumrine (1994) noted that mussels that occupied hard substrata but did not form beds were also adversely affected. Oikos, 32, 68-76.

(2013) observed that mussels from an average of 17 psu found it harder to acclimate between the salinity extremes than those from an average of 6.5 psu. Microplastics are taken up by mussels (Mytilus edulis) and lugworms (Arenicola marina) living in natural habitats Author links open overlay panel Lisbeth Van Cauwenberghe 3 Michiel Claessens 1 3 Michiel B. Vandegehuchte 2 Colin R. Janssen Under the middle emission scenario, resistance has been assessed as ‘Medium’, as less than 25% of this biotope may be lost. Therefore, colonization of new space in sheltered areas could be slow, particularly in areas where there is a low availability of adult mussels. Effect of salinity on filtration rates of mussels Mytilus edulis with special emphasis on dwarfed mussels from the low-saline Central Baltic Sea. Hence, resilience is assessed as ‘Medium’, so that sensitivity is 'Medium'. Moore & J. Stegeman). Holt, T.J., Jones, D.R., Hawkins, S.J. In addition, the high rate of faecal and pseudofaecal matter production by the mussels naturally results in siltation of the seabed, often resulting in the formation of large mounds beneath the mussel bed. Biofouling, 16, 1-15. Sensitivity assessment. Loosanoff (1962) found that in small quantities of turbid water (due to particulates) the mussel can filter out all of the particulates within a few minutes whereas in volumes >50 gallons per individual the mussel becomes exhausted before the turbidity has been significantly lowered, causing it to close its shell and die. But mobilizing amino acids may result in loss of protein, increased nitrogen excretion and reduced growth. Therefore, is unlikely that a change in turbidity by of one rank (e.g. The mean tidal range in the UK varies from 127 cm in the Shetland Islands to 972 cm at Avonmouth, in the Bristol Channel (Woodworth et al., 1991). In order to survive the mussels needed to keep moving upwards to stay on the surface. Aquatic Toxicology, 82 (1), 1-14. Newell (1979) recorded salinities as high as 42psu in intertidal rock pools, suggesting that Mytilus edulis can tolerate high salinities. (2011) investigated the effects on increased SPM concentrations on both the gape pattern and mortality in order to establish the effect that aggregate dredging will have on Mytilus edulis and other benthic invertebrates. Ecological Monographs, 51, 145-178. Marine Pollution Bulletin, 71 (1), 240-249. Habitat factor: Range of conditions: Salinity: Full, variable. The lower mortality when buried in coarse sands may be related to the greater number of individuals who were able to emerge in these conditions and emergence was to be significant for survival. Novel observations underlying the fast growth of suspension-feeding shellfish in turbid environments: Mytilus edulis. & Evans, S.V., 1989. The resilience assessments have adopted the rates used by Mainwaring et al. Sarsia, 6 , 123-33. This conclusion was reached due to significant results being displayed for human impact despite the experiment taking place during a time of high natural disturbance from El Niño–Southern Oscillation (ENSO). Water flow also affects the settlement behaviour of larvae. Reference containing the species Type Description is highlighted. Mytilus galloprovincialis has a higher thermal limit than Mytilus edulis; up to 31°C dependent on acclimation temperature (Braby & Somero, 2006), so it is potentially feasible that Mytilus galloprovincialis may replace blue mussels in the UK with gradual global warming, although there is no evidence to support this hypothesis at present.

International Biological Programme. Thieltges, D.W., 2005. As the larvae of Mytilus edulis are planktonic and are transported by water movements, barriers that reduce the degree of tidal excursion may alter the supply of Mytilus edulis to suitable habitats from source populations. Holt, T.J., Rees, E.I., Hawkins, S.J. Crassostrea gigas. Littoral and sublittoral beds are considered to have ‘Medium’ resilience (2 -10 years) to represent the potential for recovery within a few years where a proportion of the bed remains (‘Medium’ or ‘Low’ resistance). Dredging is also likely to increase the vulnerability of the remaining mussels to storm damage through the weakening of byssal attachment and creating patches in the bed (Denny, 1987). & Hoffmann, E., 2001. Commercial removal of mussels can often be responsible for the depletion of mussel stocks. & Mann, R., 1999. As a further heatwave is likely to affect this habitat before full recovery, recovery has been assessed as ‘Very Low.’ Therefore, this biotope is assessed as having ‘High’ sensitivity to marine heatwaves under the high emission scenario. The Biological Bulletin, 204 (1), 96-103. Newell, R.C., 1979. In the Wadden Sea and the North Sea, Magallana gigas overgrows mussel beds in the intertidal zone (Diederich, 2005, 2006; Kochmann et al., 2008), although larvae did show preference for settling on conspecifics before the mussels and struggled to settle on mussels with a fucoid covering. Invasion of the North American Atlantic coast by a large predatory Asian mollusc. the Mytilus island as a habitat for associated organisms is steadily changing, because it is composed of living mussels. Aquaculture, 35, 137-150. In 1993-94 the size of mussel landings was found to correlate with a reduction in the overall stock size of the area, suggesting that mussel mortality was significantly increased by the fishery. Mytilus edulis is capable of anaerobic metabolism. Blue mussels are active suspension feeders generating currents by beating cilia and are therefore not entirely dependent on water flow to supply food (organic particulates and phytoplankton). Ecophysiological importance of the isolation response of hibernating blue mussels (Mytilus edulis). Culloty, S.C., Novoa, B., Pernas, M., Longshaw, M., Mulcahy, M.F., Feist, S.W. (1998) noted that several thousand tonnes of mussels were fished in the Wash by dredgers in good years. The Marine Habitat Classification for Britain and Ireland. [UK Marine SACs Project. Mytilus edulis is probably relatively tolerant of contaminants. Based on the available evidence Mytilus edulis are considered to be resistant to periods of hypoxia and anoxia although sub-lethal effects on feeding and growth may be expected. Effects of hypoxia and organic enrichment on the coastal marine environment. Marine Life Information Network: Biology and Sensitivity Key Information Sub-programme Plymouth: Marine Biological Association of the United Kingdom. It is thought that the use of nucleating agents in the haemolymph and the maintenance of a high osmotic concentration in the mantle fluid during periods of winter isolation allows Mytilus edulis to tolerate such low temperatures (Aunaas et al., 1988). & Wethey, D.S., 2010. Similar effects could be observed through the grounding of a vessel, the dropping of an anchor or the laying of a cable, although the scale of damage clearly differs.

Systematically blue mussels consist of a group of (at least) three closely related taxa of mussels, known as the Mytilus edulis complex. Mytilus edulis is a eurythermal species, and the maximum upper thermal limit of this species appears to generally be somewhere between 25 - 28°C, above which this species experiences mortality, with tolerance related to exposure. Mytilus edulis is eurythermal and are able to withstand freezing conditions for several months. Thompson, I.S., Richardson, C.A., Seed, R. & Walker, G., 2000. & Avaca, M.S., 2011.

Gonzalez & Yevich (1976) found that Mytilus edulis could not tolerate sustained temperatures of 27°C, and feeding stopped after 25°C. Rising air temperatures can also lead to significant mortality in Mytilus edulis. Name of habitat Intertidal Mytilus edulis beds on mixed and sandy sediments Definition of habitat Sediment shores characterised by beds of the mussel Mytilus edulis occur principally on mid and lower shore mixed substrata (mainly cobbles and pebbles on muddy sediments) but also on sands and muds. Larval mortality can be as high as 99% due to adverse environmental conditions, especially temperature, inadequate food supply (fluctuations in phytoplankton populations), inhalation by suspension feeding adult mytilids, difficulty in finding suitable substrata and predation (Lutz & Kennish 1992). Programmet er baseret på den harmoniserede systemterminologi og yderligere udvidet med lokale underinddelinger. Marine heatwaves under global warming. (2008) found that the health of Mytilus edulis decreased as a result of 60 days of exposure to increased CO2, which they suggested was due to the elevated concentration of calcium ions in the haemolymph. 506., Peterborough, 96 pp. Smith & Murray (2005) observed a significant decrease in mussel mass (g/m2), density (no./m2), percentage cover and mean shell length due to low-intensity simulated bait-removal treatments (2 mussels/month) for 12 months (Smith & Murray, 2005). In The mussel Mytilus: ecology, physiology, genetics and culture (ed. The impact of hydraulic dredging for razor clams Ensis spp. from version 19.4.15, Site usage Settlement, growth and production of the mussel, Mytilus edulis L., in Morecambe Bay, England. On mudflats and sandflats, this biotope may be found alongside Cerastoderma edule beds (CerPo) and other LMU and LSA biotopes. (eds.). It has a high fecundity, a long-lived pelagic larval phase and hence high dispersal potential (>1000km). Gray, J.S., Wu R.S.-S. & Or Y.Y., 2002. These biotopes encompass the full variety of sediments ranging from mud and sand to pebble, cobbles and medium boulders; although gravel is not mentioned (Connor et al., 2004). Whilst this clearly demonstrates the ability of mussels to adapt to the various conditions to avoid dislodgement, the mussels are unlikely to adapt instantly and a sudden increase in flow is likely to result in dislodgement (Young, 1985). [Developments in Aquaculture and Fisheries Science, no. Hybrids of the two species are also commonly found in nature. Spontaneous and induced components of salinity preference behaviour in Carcinus maenas. Essink (1999) recorded fatal burial depths of 1-2 cm for Mytilus edulis and suggested that they had a low tolerance of sedimentation based on investigations by R.Bijkerk (cited by Essink, 1999). Crepidula fornicata. In the long-term (weeks) Mytilus edulis can acclimate to lower salinities (Almada-Villela, 1984; Seed & Suchanek 1992; Holt et al.,1998). Biogenic reefs (Volume IX). Further study is required to determine the length of time required for recovery of this behavioural response (Last et al., 2011). Resilience has been assessed as ‘Very low’, due to the long-term nature of sea-level rise. 2014) to only be exposed to the Pacific oyster, Magallana gigas.

Oceanography and Marine Biology: an Annual Review, 33, 245-303. Shumway, S.E., 1990. (2004) noted that the build-up of mussel mud beneath beds could result in a change from sandy to muddy substrata underneath the bed and reduce attachment resulting in increased risk of removal by storms. There is some evidence that hybrid larvae have a faster growth rate to metamorphosis than pure individuals which may leave pure individuals more vulnerable to predation (Beaumont et al., 1993). Amongst the mussels small individuals of red seaweeds including Ceramium spp., Corallina officinalis and Mastocarpus stellatus can be found. Dolmer & Svane (1994) found that in still water the strength of the attachment was 21% of the potential strength whilst at 1.94 m/sec it was 81% of the potential strength. Balseiro P., Montes A., Ceschia G., Gestal C., Novoa B. Van de Werfhorst, L.C. No direct evidence was found to assess this pressure. Shift from native mussels to alien oysters: differential effects of ecosystem engineers. 3. The lower mortality when buried in coarse sands may be related to the greater number of individuals who were able to emerge in these conditions and emergence was to be significant for survival. The reduction in growth of Mytilus edulis in fluctuating salinity regimes measured using laser diffraction patterns and the exaggeration of this effect by using tap water as the diluting medium. Mytilus edulis appears to maintain genetic homogeneity throughout its range whereas Mytilus galloprovincialis can be genetically subdivided into a Mediterranean group and an Atlantic group (Beaumont et al. However, mussel beds are prevalent in areas of high wave exposure suggesting a high resilience despite the destruction. Survival of juveniles is higher in mild than cold winters. Widdows and Donkin (1992) reported 50% mortality from a tissue burden of 20 µg/g TBT. Overburden by 5 cm of fine material (see benchmark) in a single incident is unlikely to result in significant mortality in blue mussel beds before sediments are removed by current and wave action. The Veliger, 14, 195-210. Marine Biology, 160 (8), 2073-2087. Recruitment of Mytilus edulis is often sporadic, occurring in unpredictable pulses (Seed & Suchanek, 1992), although persistent mussel beds can be maintained by relatively low levels or episodic recruitment (McGrorty et al., 1990). 441 pp., Swindon: Water Research Council on behalf of EN, SNH, CCW, JNCC, SAMS and EHS. the Menai Strait. Therefore, Mytilus edulis is recorded as having a 'High' resistance to an increase in salinity at the pressure benchmark and a 'High' resilience and this biotope is, therefore, assessed as 'Not sensitive' at the benchmark level. Brosnan & Crumrine (1994) recorded the loss of 54% of mussels from a single experimental plot on one day. It should be noted that the mussels themselves will often cause a change in substrata by the deposition of large quantities of ‘mussel-mud’ composed of faecal matter and pseudofaeces (Dare, 1976) particularly in areas of low water movement. The increased energy used for byssus production in the high flow environments may reduce the energy that is available for other biological activities (Alfaro 2006). Individuals attached to solid substrata (rock) are likely to display more resistance than individuals attached to boulders, cobbles or sediment. (1998) found that Mytilus edulis could not acclimate to temperatures above 28.5°C. Tremblay, R., Myrand, B., Sevigny, J.-M., Blier, P. & Guderley, H., 1998. On the other hand, the increased turbidity may reduce predation by visual predators such as fish and birds (Essink, 1999).
