This was based on the assumption that blue mussel reefs would provide complex habitats for fish, and improve the conditions and availability of prey organisms and hiding places for both juvenile and adult fish in the fjord. Blue mussels (~ 44 ton) were produced on ropes in the fjord from the indigenous mussel larvae stock in 2 years, 2010 and 2011.

Mussel (/ ˈ m ʌ s ə l /) is the common name used for members of several families of bivalve molluscs, from saltwater and freshwater habitats. These groups have in common a shell whose outline is elongated and asymmetrical compared with other edible clams, which are often more or less rounded or oval.

Blue mussels are well acclimated to a 5 to 20 °C temperature range, with an upper sustained thermal tolerance limit of about 29 °C for adults. The European mussel Mytilus edulis has been introduced into the northern Pacific, and the practice now flourishes widely in Japan and China. Most scallops, Pecten, Placopecten, and Amusium, are caught by offshore trawlers, although cultivation is being attempted. A wide variety of clams are cultivated—e.g., Mya arenaria and… Common mussels live in large colonies and release their gametes (eggs and sperm) synchronously (at the same time) in the water column for maximum fertilization. The mussel was also created with the ability to make extremely tough fibers, called byssus threads, that it uses to attach itself to other things.

The mussel beds stabilise the underlying sediment creating a highly complex habitat for a diverse community of plants and animals living on, within or under the bed. This area contains a range of blue mussel habitat con Wgura-tions, from large, continuous mussel beds to areas with a few small blue mussel patches surrounded by areas with low mussel coverage. Blue mussel beds show large interan-nual Xuctuations in density and population structure due to salinity, ice scouring and predation (Westerbom et al. 2002).

Key Facts. Mussels are farmed on longlines or racks in the sea, which has a negligible impact on habitat or other species. Blue mussels filter food from the water

Blue mussels are boreo-temperate invertebrates that live in intertidal areas attached to rocks and other hard substrates by strong (and somewhat elastic) thread-like structures called byssal threads, secreted by byssal glands located in the foot of the mussel.

Mussels are filter feeders, filtering detritus and plankton from the water. Their shells are usually a blueish-grey colour, though they are sometimes purple or brown. They are also known as the Blue Mussel. Blue mussels, Mytilus spp., occur on rocky and sedimentary shores worldwide where they often form dense aggregates.

These substrate types are known to be good habitats for blue mussels in the Baltic Sea area (e.g. Westerbom, 2006). Common blue mussels generate unique habitats which support considerable biodiversity in coastal regions, and are a key economic resource for the aquaculture industry. The blue mussel is a semi-sessile bivalve common on rocky intertidal habitats.

The blue mussel (Mytilus edulis) is known as a robust bivalve species, although its larviculture appears to be highly susceptible to diseases.In this study, we isolated 17 strains from induced mortality events in healthy wild-caught blue mussel adults and demonstrated that they caused between 17% and 98% mortality in blue mussel larvae in a newly developed, highly controlled Habitat and Biology: The exact range of M. edulis is not known because of the confusion with other, very similar Mytilus. In Europe it lives on all coasts that have hard substrates.Intertidal to 40 m deepattached by byssus threads to rocks and piers, within sheltered harbours and estuaries and on rocky shores of the open coast, sometimes living in dense masses wherever there are suitable Illustration of blue mussels Mytilus edulis ) used in and environmental display.

current pulling in water and plankton. Blue mussels live in dense colonies called mussel beds. When the tide comes in, the animal partially opens its shell and takes in water. Blue mussels resist dehydration during low tide by tightly closing their shells. Their major predators are sea stars, whelks,

History of Freshwater Mussels Use. From the But these days, the blue mussel responds to the crab s presence by Invasions of one organism into a new habitat frequently cause evolution — for both the It is a medium sized edible bivalve mollusc, which is harvested for food, both wild and farmed. Its habitats are in the North Atlantic ocean between the coasts of California Mussels have large, blue-black shells (also called valves) with The shells are blue-gray inside and somewhat iridescent.
