Mytilus (bivalve)
''Mytilus'' is a Cosmopolitan distribution, cosmopolitan genus of medium to large-sized edible, mainly Saline water, saltwater mussels, marine (ocean), marine bivalve molluscs in the family (biology), family Mytilidae. Description Mussels have a gray to blue-purple, fully grown shell about 5 - 10 centimeters long with an elongated oval shape. They follow the general blueprint of the mussels. They consist of a right and left half of the shell, which are held together with an elastic lock strap (ligament). The shell is made up of 3 layers: the top layer of organic material (periostracum), the middle thick layer of lime (ostracum) and the innermost, valuable, silver-white shiny mother-of-pearl layer (hypostracum). In the shell of the mussel there are two gills with gill leaves that are well supplied with blood. Between the gills is a muscular foot with the byssus gland. With the help of the protein contained in the mussel and iron filtered from the sea, this gland produces the by ...

Mytilus Edulis
The blue mussel (''Mytilus edulis''), also known as the common mussel, is a medium-sized edible marine (ocean), marine bivalve mollusc in the family (biology), family Mytilidae, the only extant family in the order (biology), order Mytilida, known as Mytilida, "true mussels". Blue mussels are subject to commercial use and intensive aquaculture. A species with a large range, the blue mussel leaves empty shells that are commonly found on beaches around the world. Systematics and distribution The ''Mytilus edulis'' complex Systematically blue mussel consists of a group of (at least) three closely related taxa of mussels, known as the ''Mytilus edulis'' complex. 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. The distribution of the component taxa has been recently modified as a result of human activity. The taxa can hybridi ...

Mytilus Californianus
The California mussel (''Mytilus californianus'') is a large edible mussel, a marine bivalve mollusk in the family Mytilidae. This species is native to the west coast of North America, occurring from northern Mexico to the Aleutian Islands of Alaska. California mussels are found clustered together, often in very large aggregations, on rocks in the upper intertidal zone on the open coast, where they are exposed to the strong action of the surf. Shell description The shell of this species is thick and is often in length, sometimes larger still. The shell is blue on the outside with a heavy brown periostracum which is usually worn off except near the growing edge of the shell. The beaks of the shell are often eroded. The shell has coarse radial ribbing and irregular growth lines on the outer surface. The inner surface of the shell is blue and faintly pearly. Like other mytilids, the animal is attached to the substrate with a very strong and elastic byssus. The shell is primari ...

Indigenous Peoples Of The Americas
In the Americas, Indigenous peoples comprise the two continents' pre-Columbian inhabitants, as well as the ethnic groups that identify with them in the 15th century, as well as the ethnic groups that identify with the pre-Columbian population of the Americas as such. These populations exhibit significant diversity; some Indigenous peoples were historically hunter-gatherers, while others practiced agriculture and aquaculture. Various Indigenous societies developed complex social structures, including pre-contact monumental architecture, organized city, cities, city-states, chiefdoms, state (polity), states, monarchy, kingdoms, republics, confederation, confederacies, and empires. These societies possessed varying levels of knowledge in fields such as Pre-Columbian engineering in the Americas, engineering, Pre-Columbian architecture, architecture, mathematics, astronomy, History of writing, writing, physics, medicine, Pre-Columbian agriculture, agriculture, irrigation, geology, minin ...

Mariculture
Mariculture, sometimes called marine farming or marine aquaculture, is a branch of aquaculture involving the cultivation of marine organisms for food and other animal products, in seawater. Subsets of it include ( offshore mariculture), fish farms built on littoral waters ( inshore mariculture), or in artificial tanks, ponds or raceways which are filled with seawater ( onshore mariculture). An example of the latter is the farming of plankton and seaweed, shellfish like shrimp or oysters, and marine finfish, in saltwater ponds. Non-food products produced by mariculture include: fish meal, nutrient agar, jewellery (e.g. cultured pearls), and cosmetics. Types Onshore Although it sounds like a paradox, mariculture is practiced onshore variously in tanks, ponds or raceways which are supplied with seawater. The distinguishing traits of onshore mariculture are the use of seawater rather than fresh, and that food and nutrients are provided by the water column, not added artific ...

Brackish Water
Brackish water, sometimes termed brack water, is water occurring in a natural environment that has more salinity than freshwater, but not as much as seawater. It may result from mixing seawater (salt water) and fresh water together, as in estuary, estuaries, or it may occur in brackish Fossil water, fossil aquifers. The word comes from the Middle Dutch root '':wikt:brak#Dutch, brak''. Certain human activities can produce brackish water, in particular civil engineering projects such as dikes and the flooding of coastal marshland to produce brackish water pools for freshwater prawn farming. Brackish water is also the primary waste product of the Osmotic power, salinity gradient power process. Because brackish water is hostile to the growth of most terrestrial plant species, without appropriate management it can be damaging to the environment (see article on shrimp farming, shrimp farms). Technically, brackish water contains between 0.5 and 30 grams of salt per litre—more ofte ...

Mytilus Trossulus
''Mytilus trossulus'', the Pacific blue mussel, bay mussel or foolish mussel, is a medium-sized edible marine bivalve mollusc in the family Mytilidae. ''Mytilus trossulus'' is one of the three principal, closely related taxa in the ''Mytilus edulis'' complex of blue mussels, which collectively are widely distributed on the temperate to subarctic coasts the Northern Hemisphere, and often are dominant inhabitants on hard substrates of the intertidal and nearshore habitats. Distribution ''Mytilus trossulus'' is the main native intertidal mussel in the Northern Pacific. In North America it is found from California to Alaska, and in Asia from Hokkaido northwards. At its southern limits, it hybridizes with '' Mytilus galloprovincialis'' (the Mediterranean mussel), which has been introduced to the Pacific by human activity. In the North Atlantic, ''M. trossulus'' is found on the U.S. coast of Maine and northwards to Canada, as well as in scattered localities on North European coasts. ...

Sealifebase.org
or Chilean blue mussel, ''Mytilus chilensis'', is a species of Mytilus (bivalve), blue mussel native to the coasts of List of marine molluscs of Chile, Chile from Biobío Region (37 ºS) to Cape Horn (55 ºS). Genomic evidence has confirmed that the native Chilean blue mussel is genetically distinct from the Northern Hemisphere ''M. edulis'', ''M. galloprovincialis'' and ''M. trossulus'' and also genetically different from ''Mytilus platensis'','' ''the other species of smooth shelled mussel from South America.
