'''''Limnoperna fortunei''''', the |
'''''Limnoperna fortunei''''', the '''golden mussel''', is a medium-sized [[Fresh water|freshwater]] [[Bivalvia|bivalve]] [[mollusc]] of the [[Family (biology)|family]] [[Mytilidae]]. The native range of the species is China, but it has accidentally been introduced to South America and several Asian countries where it has become an [[invasive species]]. It is considered to be an [[ecosystem engineer]] because it alters the nature of the water and the bottom habitats of lakes and rivers and modifies the associated [[invertebrate]] communities. It also has strong effects on the properties of the water column, modifying nutrient proportions and concentrations, increasing water transparency, decreasing phytoplankton and zooplankton densities, on which it feeds, and enhancing the growth of aquatic macrophytes. Because mussels attach to hard substrata, including the components of industrial, water-treatment and power plants, they have become a major biofouling problem in the areas invaded. |

The size of adult individuals is usually around 20-30 mm, but specimens up to 45 mm have been reported. |
The larvae of the golden mussel are small (around 100 micrometers), and live in the water column until they are ready to settle. The size of adult individuals is usually around 20-30 mm in length, but specimens up to over 45 mm have been reported. The outer surface of the shell is golden to dark brown, whereas internally it is nacreous, pearly white to purple. The valves are very thin and brittle, and there are no hinge teeth. The mantle is fused on the dorsal side and between the exhalant siphon and the inhalant aperture. Water enters the mussel's mantle cavity through the inhalant aperture, and after describing a series of movements during which suspended particles are filtered out and either ingested, digested in the gut, and the undigested remains egested as feces, or discarded as pseudofeces, is expelled through the exhalant siphon. These water currents are also used for respiration and for discarding excretion waste products. The shell attaches to hard substrates by byssal threads, forming beds of closely packed animals. Internally, a series of muscles attached to the valves are responsible for its closure, retraction of the byssus, and movements of the foot<ref>{{Cite book|url=https://link.springer.com/chapter/10.1007/978-3-319-13494-9_1|title=Limnoperna Fortunei|last=Morton|first=Brian|date=2015|publisher=Springer, Cham|isbn=9783319134932|series=Invading Nature - Springer Series in Invasion Ecology|pages=3–41|language=en|doi=10.1007/978-3-319-13494-9_1}}</ref><ref>{{Cite journal|last=Morton|first=Brian|date=1973|title=Some aspects of the biology and functional morphology of the organs of feeding and digestion of Limnoperna fortunei (Dunker) (Bivalvia: Mytilacea)|url=|journal=Malacologia|volume=12|pages=265-281|via=}}</ref> |

The golden mussel's life span is around 2 years. Growth is fastest during the summer, decreasing sharply in winter. During the first year mussels typically grow to ~20 mm, reaching ~25-30 mm at the end of the second year. Growth rates and final size depend largely on water temperature and the time of the year when the individuals are born, although calcium concentrations, pollution, food availability and intraspecific competition may play important roles as well<ref>{{Cite book|url=https://link.springer.com/chapter/10.1007/978-3-319-13494-9_6|title=Limnoperna Fortunei|last=Nakano|first=Daisuke|last2=Kobayashi|first2=Takuya|last3=Sakaguchi|first3=Isamu|date=2015|publisher=Springer, Cham|isbn=9783319134932|series=Invading Nature - Springer Series in Invasion Ecology|pages=105–118|language=en|doi=10.1007/978-3-319-13494-9_6}}</ref><ref>{{Cite journal|last=Boltovskoy|first=Demetrio|last2=Cataldo|first2=Daniel H.|date=1999-12-01|title=Population dynamics of Limnoperna fortunei, an invasive fouling mollusc, in the lower Parana river (Argentina)|url=https://doi.org/10.1080/08927019909378417|journal=Biofouling|volume=14|issue=3|pages=255–263|doi=10.1080/08927019909378417|issn=0892-7014}}</ref><ref>{{Cite journal|last=Morton|first=B.|date=1977|title=The population dynamics of Limnoperna fortunei (Dunker 1857) (Bivalvia: Mytilacea) in Plover Cove Reservoir, Hong Kong|url=|journal=Malacologia|volume=16|pages=165-182|via=}}</ref><ref>{{Cite journal|last=Maroñas|first=M.

==Ecology== |

The golden mussel is a [[filter feeder]]. When it occurs in great numbers it filters large quantities of water and has a significant effect on the amount of suspended material in the water column. Its faeces and pseudofeces are retained in the sediment and supply abundant food for [[detritivore]]s. It has a [[plankton]]ic larval stage and populations can grow fast. The adults live close together in aggregations that alter the substrate of the lakebed. When this happens there is a considerable increase in associated invertebrates that can make use of the nooks and crannies among the mussels, and feed on their faeces. However, there is a concomitant great decline in the presence of native freshwater mussels in the family [[Unionidae]].<ref name=Karatayev/> |
|||
== Distribution and geographic spread == |
|||
In a research study undertaken in the Rio Tercero Reservoir in Argentina,it was found that the preferred habitat of the golden mussel was stones and gravel. It tolerated sandy bottoms and generally avoided silt. However, one of the largest aggregations found was on a [[plastic bottle]] on a silty bottom.<ref name=Karatayev/> On sandy bottoms, aggregations were often attached to large sand grains that were glued together with byssus threads. Nestling among the mussels were a wider range of invertebrate species than were found in the surrounding areas. A particularly noticeable increase occurred in [[Gastropoda|gastropods]], [[leech]]es, [[Caddisfly|caddisflies]], [[mayfly]] larvae and [[Chironomidae|midge larvae]]. The only invertebrates that decreased in number were the segmented worms ([[Oligochaeta]]) which burrow in the sediment and perhaps found it depleted of oxygen by the degradation of the mollusc faeces.<ref name=Karatayev/> |

''L. fortunei''<nowiki/>'s native range is most probably the Pearl River basin, in southern China. Its presence in Laos, Cambodia, Thailand and Vietnam is probably the result of historical human migrations<ref>{{Cite journal|last=Morton|first=B.|last2=Dinesen|first2=G.|date=2010|title=Colonization of Asian freshwaters by the Mytilidae (Bivalvia): A comparison of Sinomytilus harmandi from the Tonle-Sap River, Phnom Penh, Cambodia, with Limnoperna fortunei|url=|journal=Molluscan Research|volume=30|pages=57-72|via=}}</ref>.

The study compared the golden mussel with the [[zebra mussel]] (''Dreissena polymorpha'') which is another aggressive invasive species. The golden mussel is more tolerant of increased salinity, low [[pH]] values and higher temperatures than the zebra mussel. The study considered the likely effect if the golden mussel were to reach North America. It seemed likely that it would be able to colonise water masses that did not suit the zebra mussel, and thus would devastate native [[unionid]]s in their few remaining strongholds.<ref name=Karatayev/> |

The effects of this process on the water column include the decrease of suspended particles, water column primary production, and the concomitant increase in water transparency. which in turn enhances the growth of submerged macrophytes<ref name=":3" />.

Limnoperna fortunei, the golden mussel, is a medium-sized freshwater bivalve mollusc of the family Mytilidae. The native range of the species is China, but it has accidentally been introduced to South America and several Asian countries where it has become an invasive species. It is considered to be an ecosystem engineer because it alters the nature of the water and the bottom habitats of lakes and rivers and modifies the associated invertebrate communities. It also has strong effects on the properties of the water column, modifying nutrient proportions and concentrations, increasing water transparency, decreasing phytoplankton and zooplankton densities, on which it feeds, and enhancing the growth of aquatic macrophytes. Because mussels attach to hard substrata, including the components of industrial, water-treatment and power plants, they have become a major biofouling problem in the areas invaded.
Description
The larvae of the golden mussel are small (around 100 micrometers), and live in the water column until they are ready to settle. The size of adult individuals is usually around 20-30 mm in length, but specimens up to over 45 mm have been reported. The outer surface of the shell is golden to dark brown, whereas internally it is nacreous, pearly white to purple. The valves are very thin and brittle, and there are no hinge teeth. The mantle is fused on the dorsal side and between the exhalant siphon and the inhalant aperture. Water enters the mussel's mantle cavity through the inhalant aperture, and after describing a series of movements during which suspended particles are filtered out and either ingested, digested in the gut, and the undigested remains egested as feces, or discarded as pseudofeces, is expelled through the exhalant siphon. These water currents are also used for respiration and for discarding excretion waste products. The shell attaches to hard substrates by byssal threads, forming beds of closely packed animals. Internally, a series of muscles attached to the valves are responsible for its closure, retraction of the byssus, and movements of the foot[2][3]
Reproduction, growth and life cycle
Limnoperna fortunei is dioecious, with approximately equal numbers of males and females and very small proportions of hermaphrodites[4]. Sexual maturation occurs early, at about 5-6 mm[5]. Ova and sperm are liberated into the water, most probably simultaneously within the same area, where fertilization occurs producing a series of planktonic developing forms including a trochophore and a veliger around 150 micrometers in size. The final larval stage before settling on a substrate, which takes between 20 days (at 20ºC) and 12 days (at 28ºC) is the plantigrade larva (~250 micrometers)[6][7]. The reproductive cycle has been described for both Asian and South American populations, and is clearly associated with water temperature. In South America, at water temperatures between ~10 and 30ºC, larvae are produced continuously for 6–10 months of the year between spring and autumn, often with conspicuous peaks around November and April[8]. In Japan, at water temperatures around 5-20ºC, larval production is restricted to 1–2 summer months[9]. Larval densities during the reproductive period are very variable, but normally average around 6000 larvae per cubic meter of water, although values in excess of 20000 larvae per cubic meter of water have been reported[8]. In waterbodies where strong cyanobacterial blooms occur, reproduction can be suppressed altogether because cyanobacterial toxins (microcystin) engender massive larval mortalities[10].
The golden mussel's life span is around 2 years. Growth is fastest during the summer, decreasing sharply in winter. During the first year mussels typically grow to ~20 mm, reaching ~25-30 mm at the end of the second year. Growth rates and final size depend largely on water temperature and the time of the year when the individuals are born, although calcium concentrations, pollution, food availability and intraspecific competition may play important roles as well[11][12][13][14].
Distribution and geographic spread
L. fortunei's native range is most probably the Pearl River basin, in southern China. Its presence in Laos, Cambodia, Thailand and Vietnam is probably the result of historical human migrations[15]. Between 1965 and 1990, it spread into Hong Kong, Korea, Taiwan and Japan[16][17]. Around 1990 it appeared in Argentina[18]. By 2006 it had spread to Uruguay, Paraguay, Bolivia, and Brazil. In 2017, in South America it was present in two major basins (Río de La Plata, including the Paraguay-Paraná and Uruguay rivers, and the São Francisco basin), as well as several smaller watersheds (Mar Chiquita, Guaíba, Patos-Mirim, Tramandaí)[19][20]. Its spread northwards in South America (Amazon, Orinoco, Magdalena basins), as well as into Central and southern North America, seems very likely[21][22][23][24].
Ecology and environmental impacts
L. fortunei is a strictly freshwater species, although it can tolerate brackish waters of up to 23 per mil (23 grams of salt per liter of water) for restricted periods of time (hours)[25].
The mussel needs hard substrata for settling, like rocks, wood, floating and submerged plants, mussel shells, crustaceans, etc. Although it cannot live on fine loose sediments, muddy areas stabilized by roots or fibrous debris are also occasionally colonized[26][27]. Because in most waterbodies colonies are intensively preyed upon (mostly by fishes), colonization is often restricted to crevices inaccessible to large predators. Mussel beds cover extensive areas at densities often in excess of 200,000 animals (including early juveniles below 1 mm in size) per square meter, but their thickness rarely exceeds 7–10 cm, with most adults being at least partially attached to the substrate. Settlement of new recruits is higher in established mussel beds than elsewhere, and juveniles often attach to larger shells, but eventually move deeper towards the substrate[26][28]. The very few surveys on population densities over large areas reported around 1000 mussels per square meter[27][29]. In lakes, reservoirs and rivers, mussel colonization is often restricted to coastal areas, where hard substrata are more abundant because loose sediments are winnowed away from these higher energy zones towards deeper areas.
The golden mussel is a filter-feeder. Adult individuals process around 1 liter of water every 10 hours[30], retaining organic particles, including phytoplankton and zooplankton, and egesting or rejecting unwanted materials in mucous strands that settle on the bottom. The effects of this process on the water column include the decrease of suspended particles, water column primary production, and the concomitant increase in water transparency. which in turn enhances the growth of submerged macrophytes[30]. Further, nutrient (ammonia, nitrate, phosphate) concentrations in the water are increased, favoring the growth of often toxic cyanobacteria[31]. Bottom deposits and the sediments retained among the mussels are enriched with organic matter. Benthic organisms and those that feed on detritus in general, including many fish species, benefit from this additional source of energy. Benthic invertebrates, in particular, are usually more diverse and abundant in mussel beds than elsewhere[32].
In South America, adult L. fortunei is preyed upon by at least 50 fish species[33]. Introduction of this mussel in South America has been tentatively associated with large increases in the landings of the commercially most important detritivorous fish species of the Río de la Plata basin, Prochilodus lineatus[34]. In Argentina and in Japan, up to over 90% of the mussel's production is lost to predation[35][36], mostly presumably by fishes, but also probably by other invertebrates, waterfowl, turtles, and mammals[35]. In South America, the planktonic larvae of the golden mussel are actively consumed by fish larvae of ~20 species, especially from the orders Characiformes and Siluriformes. This diet has been shown to significantly improve fish growth, especially during the earliest developmental stages[37][38][39].
The evidence of whether these impacts are positive or negative for the ecosystems invaded is mixed and debatable. This issue is further complicated by the fact that the same forcing can have opposite results. For example, while the provision of organic matter from the mussel's feces and pseudofeces and the protection conveyed by its colonies can enhance the abundance and diversity of benthic invertebrates, this extra load of organic matter can also deplete near-bottom oxygen levels, thus decreasing the abundance and diversity of benthic invertebrates[40].
Impacts on human activities
As opposed to its effects on the environment, those on man-made structures are clearly negative. The mussel has caused severe fouling problems in both Asia and in Souh America. The facilities affected incude power plants (nuclear, hydroelectric, thermal), water and wastewater processing plants, refineries, steel mills, fish culture installations, water transfer canals and aqueducts, watercraft, agricultural irrigation systems, balancing reservoirs and balancing tanks. The plant components that are most commonly fouled by the mussels are pipes, heat exchangers and condensers, strainers, filters, trash racks, grates, screens, penstocks, pumps, nozzles, and sprinklers, vent lines, and air release valves, fire protection equipment, grit chambers, flocculators, holding ponds, storage tanks, pump suction chambers, pump wells, water intake tunnels, pump and turbine shafts, seals, and wear rings, boat engines (cooling water ducts, filters, pumps) and submerged rudder and propulsion components, sand filtration systems, submerged monitoring instrumentation, and level gauges. The problems involved include clogging by living mussels or by dead, dislodged shells, pressure loss, overheating, corrosion, abrasion and wear, jamming of moving components, sealing failures, deterioration of metal, concrete and other materials, and sediment accumulation[41]. However, objective estimates of the economic losses involved are practically unavailable. Fouling by L. fortunei has not caused a single definitive plant shutdown. Nevertheless, operation at below-standard regimes and even temporary plant shutoffs have often been reported. Numerous fouling control methods have been proposed and tested, either in laboratory conditions only, or in actual operating environments. These include antifouling materials and coatings, manual/mechanical cleaning, filtration, chemical treatments, thermal shock, anoxia and hypoxia, desiccation, ozonation, ultraviolet treatment, electric currents, ultrasound, manipulations of flow speed, biological control, and various miscellaneous methods[42][43][44][45][46][47][48][49][50] [41-49].
