  Mytilus edulis is gregarious, and can form very dense beds, with young mussels settling to colonise any available space between individuals already attached to the bed by super-strong byssal threads. These threads (also known as the beard to the cook) help to maintain their position in the bed, even in strong currents and storms. Researchers studied genetic variation in the marine mussel Mytilus edulis around Long Island, New York. They measured the frequency of a particular allele (lap^94) for an enzyme involved in regulating the mussel's internal saltwater balance. Mytilus californianus - this mussel is a filter feeder, feeding on plankton. They are the main source of food for both the Ochre Sea Star (Pisaster Ochracus) and the rock whelk (Nucella emarginata). They attach themselves to rock substrates with adhesive bistle fibers that are strong enough to endure the pounding force of countless waves.

While ‘b’ value of L. falcipinnis was a positive allometric growth which implies that there was increase in body weight with corresponding increase in total length of the fish. There was also a positive correlation of r= for innis and r = for us. These areAuthor: Kolawole-Daniels Ao, Fola-Mathews Opeyemi Omolara, Nicholas Eteobong.

Mytilus edulis chilensisfrom the Falkland Islands is synonymous with northern Mytilus edulis (McDonald et al., ). edulis is the most wide-ly distributed species within the genus and has the ability to withstand a wide range of fluctuating envi-ronmental conditions (Seed and Richardson, and references therein).

Within a certain range of algal concentrations the blue mussel Mytilus edulis is continuously filtering with a constant rate (e.g., [4, 5]).Therefore, when a group of blue mussels is placed in an aquarium with well-mixed seawater added algal cells (retained with % efficiency by the mussels) from a culture at a constant rate (P) by means of a dosing pump and, further, with a constant through Cited by: Mytilus edulis has been harvested for centuries.

Blue mussel shells have been found in kitchen middens dated at B.C. Until the 19 th century, blue mussels were harvested from wild beds in most European countries for food, fish bait and as a fertilizer.

The initial step for mussel aquaculture was based upon storage and relaying fishery products. This paper examines the reproductive cycles of three ecologically important marine bivalves-Modiolus modiolus (L.), Cerastoderma edule (L.), and Mytilus edulis L. in Strangford Lough, Northern Ireland over a period of almost five years.

In Europe it lives on all coasts that have hard idal 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.

Near the front end is the hinge and the elastic ligament that pushes the shell open when the muscles inside relax.
