Mussels are small-shelled creatures found in both salt and freshwater. However, most people only eat mussels found in salt water. Mussels are traditionally steamed with lemon juice, garlic, and ...
Depuration of seafood is the process by which marine or freshwater animals are placed into a clean water environment for a period of time to allow purging of biological contaminants (such as Escherichia coli) and physical impurities (such as sand and silt). The most common subjects of depuration are bivalves such as oysters, clams, and mussels.
The black mussel is a filter feeder that eats floating scraps of algae and phytoplankton. It is threatened by the invasion of the fast-growing and hardy Mediterranean mussel, which outcompetes it for space. Particulate organic matter is the major food source of many filter-feeding bivalves including C. meridionalis.
Droughts, forest clearing, farming, use of dams for water management, and changes in water temperature can all pose threats to freshwater bivalve populations. Restoration efforts focus on rebuilding lost mussel populations in the wild and using those mussels to improve and protect water quality and restore broader ecosystems. [2] [3]
The quagga mussel shell is generally black, yellow, and/or zig-zagged. However, a large range of shell morphologies is seen, including a distinct morph in Lake Erie that is pale or completely white. The shell has a rounded carina and a convex ventral side. The quagga mussel resembles the zebra mussel, just as its namesake (quagga) resembles the ...
The European mussel is similar in shape and color to the brown mussel and shares its native habitat on the south-western coast of Africa. [2] The European mussel is also more resistant to human disturbance such as use for baits and consumption. [3] It is out-competing the brown mussel as it is more resistant to certain parasites. The black ...
Black mussel Choromytilus meridionalis (Namibia to Tsitsikamma) [2] [3] Half-hairy mussel Gregariella petagnae (Namibia to central KwaZulu-Natal) [2] [4] Ear mussel Modiolus auriculatus (Port Elizabeth to Mozambique) [2] Mediterranean mussel Mytilus galloprovincialis (Orange river to Eastern Cape) [2] [3] Brown mussel Perna perna (Cape Point to ...
A common feature of the shells of mussels is an asymmetrical shell which has a thick, adherent periostracum. The animals attach themselves to a solid substrate using a byssus . A 2020 study of the phylogeny of Mytilidae recovered two main clades derived from an epifaunal ancestor, with subsequent lineages shifting to other lifestyles, and ...
