In macro-ecological terms, mussels and their bivalve kin are the intestines of coastal ecosystems. "It's a super-filter … Under optimal conditions, bivalves tend to filter the ambient water at a maximum rate but under suboptimal environmental conditions, including low or very high algal concentrations, the filtration rate is reduced. "It's a super-filter in the marine world, filtering up to 25 litres of water a day," says marine biologist Leila Meistertzheim. They are filter feeders so your tank needs lots of floating food to keep them alive. They have two apertures, or openings—one that draws in water and food, and one that expels filtered water and waste.

Simply defined, a tipping point is the point when a number of changes or incidents become significant enough to cause a large change in the way the system functions. Richard Luthy, an environmental engineer from California's Stanford University, says that, in most cases, mussels harvested from contaminated waters should not be eaten. Filters. Mussels play an important role in nutrient cycling, removing organic matter from the water, excreting dissolved nutrients back into it, and depositing these nutrients in the sediment. Freshwater mussels are filter feeders. Mussels "recycle" these nutrients by feeding on the algae, says Eve Galimany, a researcher of the US National Oceanic and Atmospheric Administration's Milford Laboratory who has experimented with mussels in the Bronx River in New York. The nutrients in these substances encourage the proliferation of algae, which in turn starves the water of oxygen, upsetting the ecosystem.
