The pea clams, or fingernail clams, are fairly widespread in Michigan but relatively little is known about the range and status of individual species (Figure 1). Unionid mussels and pea clams are native to North America, while Asian clams and zebra and quagga mussels are exotic to this continent. The Asian clam (Corbicula fluminea) was

2022年9月9日 · The native pea or fingernail clams (Sphaeriidae) are common, relatively tiny, thin-shelled clams about which little is known. The most diverse and well-understood group of Michigan mussels are the unionid mussels (Unionidae).

2023年3月15日 · No, there are not clams in lake michigan. Do the Great Lakes have clams? A group of native freshwater mussels are dying off in the lakes and rivers of the Great Lakes region, and children are noticing. These mussels are interesting and long-lived creatures that partly bury themselves in the water bottom.

In no time, the mussels proliferated in Lake Erie's waters, colonizing vast surfaces such as stones, vegetation and, preferentially, the shells of live, native mussels. Unable to open their shells under the weight of zebra mussels, infested unionids die within a year or two.

shell coils to the left. A diverse native mollusk fauna once lived in Lake Michigan’s shallow waters along the Chicago coastline. Habitat transformation, pollution, and invasive species, namely the zebra and quagga mussels, have all but eradicated the native bivalves and gastropods. Millions of quagga mussel shells are

2020年2月18日 · For each species, there is a detailed list of characteristics, tips for identifying them, a number of photos of the outside and inside of the shells and a distribution map.

Clams also produce over one million tons of shells per year in Lake Pontchartrain, which is converting soft unstable bottoms to productive fisheries habitat. In addition, Rangia clams provide a food source for blue crabs, many fish species, shrimp and waterfowl.

One of the most devastating ecological problems resulting from the recent invasion of North America by zebra mussels (Dreissena polymorpha) has been the virtual elimination of native clams or unionids from infested waters. Zebra mussels readily colonize clam shells, disrupting feeding, movement, and reproduction.

Shell beaches backed by berms more than a meter high once characterized the Lake Borgne facing shorelines of the Biloxi Marsh Complex and the western shore of Lake Borgne, with Rangia clam shell deposits (Kemp and Day 2017).

This paper reports on a morphological analysis of the clams fished from the Ashtamudi Lake, the subsequent comparison of the shell morphologies of southern Indian Tapetinae and the correct identification of the Ashtamudi Lake short-neck clam.
