The Atlantic ribbed mussel (Modiolus demissus), which has a thin, strong, yellowish brown shell, occurs from Nova Scotia to the Gulf of Mexico. When buried in the sediment, Ribbed mussels play a critical role in the health of a salt marsh by exhibiting in Rhode Island salt marshes as filter feeders, removing bacteria, Geukensia demissa is a species of mussel, a marine bivalve mollusk in the family Mytilidae, the true mussels. A ribbed mussel uses this organic matter to build body and shell, and excreting excess organic material to the sediment making it available for other invertebrates and fish to consume; and providing essential nourishment that enhance plant life within a wetland and contributes to salt marsh growth. Particles of organic nutrients are processed into inorganic matter by the ribbed mussel. Distribution This species is native to the Atlantic coast of North America. Ribbed mussel (Geukensia demissa, hereafter mussels) live in aggregations around cordgrass stems in intermediate and high elevation marsh platforms. They are helping to purify the water. The Atlantic ribbed mussel, Geukensia demissa, is found in intertidal habitats, mainly salt marshes, along the North American Atlantic Coast (Abbott 1974).

When mussels are present in large numbers, they may become underwater gardens that in turn attract fish to feed, including their host fish. Unfortunately, quite a few ribbed mussel bed populations along the northern Jersey Shore in Raritan Bay and Sandy Hook Bay, have disappeared or are slowly diminishing in number due to erosion, sea level rise, and increasing urban development that are eating away at the fringes of tidal wetlands. Though the mussels are on the inside of the sock now, over the next few months, they will gradually move to the outside of the sock in their continuing quest for food and nutrients. remain partially exposed. Ribbed mussels were found to be fairly ubiquitous across Barataria Bay, with densities across the salinity gradient similar to other mean densities reported for Gulf ribbed mussel populations. Ribbed mussels play a critical role in the health of a salt marsh and are considered to be "ecosystem engineers" because they modify a wetland, making it more suitable for themselves and other organisms. Other undesirable particles and chemicals are bound in the mussels' pseudo feces and deposited to the bottom of the water column. One of the most valuable functions performed by ribbed mussels is capturing organic matter from the water column when they feed. Ribbed mussels have adapted to constantly changing situations within an estuary. Save Coastal Wildlife nonprofit has formed a partnership with Women of the Cloud Forest Inc to raise funds for both organizations. Summary: This article gives a brief description of the mussel. Save The Bay, 1998. Erosion is increasing along seaward margins of tidal wetlands due to sea level rise and increasing intense storms from global climate change. Within that group it collectively is included in a diverse group called ‘mussels.’ This mussel was formerly placed in the genus Modiolus. Introduced in some places along the … A study in the Bronx River found that ribbed mussels removed high amounts of nitrogen from local waters. Brief Description: Ribbed mussels were selected for this proposed reef restoration due to their niche in maintaining ecosystem health in estuarine benthic environments. During this feeding process, the mussels "clean" the water they live in by removing phytoplankton and the bacteria and fungi that are attached to the non living organic particles they have removed from the water column. Extended ribbed mussel populations can help improve water quality in local tidal waters. MAKE A DIFFERENCE! Also given is conservation information on this species. Shellfish aquaculture is gaining acceptance as a tool to reduce nutrient over enrichment in coastal and estuarine ecosystems through the feeding activity of the animals and assimilation of filtered particles in shellfish tissues. Please join Save Coastal Wildlife nonprofit & be the voice for coastal wildlife along the Jersey Shore. Ribbed mussel is a common name of: Aulacomya atra, a southern hemisphere mussel species Geukensia demissa, a North American mussel species This disambiguation page lists articles associated with the title Ribbed mussel. The mussel socks can be placed in areas where ribbed mussel beds are in decline or are nonexistent. The ribbed mussel has a narrow blunt pointed head that is attached to submerged substrata. Shells are usually glossy appearing olive-brown to brown-black with some yellow to a white on the outside and white on the interior with purplish tints. They may be smooth or ribbed The New Zealand form ( Aulacomya maoriana ) is smaller than its South American counterpart and has a finer radial sculpture, suggesting that it … Ribbed mussel beds are being eroded and lost due to sea level rise and erosion from more intense storms.

The ribbed mussel has a narrow blunt pointed head that is attached to submerged substrata. . They have been found to generally enhance cordgrass production and persistence, and also increases cordgrass survival during desiccation events by enhancing water storage and reducing salinity stress (Angelini et al., 2016 ). Particles of organic nutrients The mussel's shells provide an important substrate for algae and insect larvae to attach to. Studies have shown that size, growth rate, and settlement rates of mussels decrease with increasing tidal height from increasing intense storms from global climate change. The goal of this study was to identify sources of variation regarding the distribution of ribbed mussel filtration services. They anchor themselves with byssal threads, which By fall, the mussels have grown to about half the length of a person’s thumb, and are ready to be collected for a mussel sock, or a long mesh tube that the mussels will placed inside, somewhat akin to a sock.

Ribbed mussels are related to blue mussels, but are largely not fit to eat by people due to being rich in organic bacteria. are processed into inorganic matter by the ribbed mussel. This helps maintain uniform shell sizes because the smaller mussels aren’t competing against their larger brothers. Ecology The ribbed mussel is a filter feeder, which eats the blue mussel that attaches to a piling or dock. The shell of a ribbed But mussels can also remove bacteria such as E. coli, while trapping sediment that can cloud up an estuary to suppress the growth of aquatic plant life.
