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.
The mussels present a food source to waterfowl and have caused bird numbers to double over the last 30 years. By the end of winter, birds decimate zebra mussel populations and reduce them by 95–99% up to the maximum depth reachable by birds of c. 10 metres (33 ft).
In June 2008, the mussels were confirmed in Lake Granby, Colorado. Larval quagga mussels were found in the water. [23] After 5 years of negative testing Lake Granby, Colorado has been classified as a negative waterbody for quagga mussel veligers. Quagga mussels are now in all parts of Lake Powell on the Utah and Arizona border.
The freshwater pearl mussel (Margaritifera margaritifera) is an endangered species of freshwater mussel, an aquatic bivalve mollusc in the family Margaritiferidae.. Although the name "freshwater pearl mussel" is often used for this species, other freshwater mussel species (e.g. Margaritifera auricularia) can also create pearls and some can also be used as a source of mother of pearl.
The Dreissenidae are a family of small freshwater aquatic bivalve molluscs, commonly called mussels although not at all closely related to true mussels. The shells of these bivalves are shaped somewhat like those of true mussels, which they also resemble in attaching themselves to a hard substrate such as stone using a byssus; however, this group is more closely related to the venus clams ().
Closed, cooked mussels mean that the mussel had died before cooking which can be dangerous to eat. Cleaning mussels is an important step when preparing your dish. The shell of the mussel is ...
However, they do not colonize bare rock easily, instead preferring the shelter of pre-existing mussels and their biological filaments. Mussels attach themselves to the hard surfaces using their thread-like byssus. Given the right circumstances, California mussels can grow up to 200 mm (8 inches) in length and may live for more than 20 years.
How long do symptoms last? They peak at 24 to 48 hours but can last up to 72 hours, says Dr. Dibba. Norovirus tends to hit hard and then fade fairly quickly. Symptoms do ramp up in intensity, however.
