Mussels are filter feeders and, consequently, act as water clarifiers and organic nutrient sinks. Mussels may also be significant aquatic decomposers because they filter suspended organic detritus and bacteria..
What biological organisms can mussels use for their nutrition?
Mussels mostly stay in one place, eating plankton that they filter from the water. Because they are filter feeders, they sometimes consume bacteria and toxins, making them potentially dangerous for you to eat..
What is the biology of freshwater mussels?
NATURAL HISTORY. DESCRIPTION: Freshwater mussels are bivalve mollusks that have a two- valved hard shell, a soft body with respiratory, digestive and reproductive organs, and a muscular foot for locomotion, burrowing and orientation. The shiny layer inside the shell is called the nacre, or mother of pearl..
What is the conservation status of freshwater mussels?
Unfortunately, for all their allure, freshwater mussels are the most endangered group of organisms in the United States. Water pollution has wreaked havoc on these clean-water-loving animals, and dams have deteriorated water quality and separated mussels from the host fish on which their survival depends..
Ecological Role Mussels play a key role in aquatic environments and are considered to be "ecosystem engineers" because they modify aquatic habitat, making it more suitable for themselves and other organisms.
This course will address key characters for identification of freshwater mussels and will provide opportunities in the laboratory to practice with dichotomous
Are freshwater mussels endangered?
Freshwater mussels are the most imperiled group of animals in North America, with 66% of species at risk. Mussel populations are declining globally, but the factors contributing to these declines are largely unknown.

What do we need to know about mussels for Conservation?
indicators for mussels. 22 In addition to analyzing which physical factors affect freshwater mussels, more work is needed in learning about the life histories of each species, which would allow for more effective conservation. We need genetic analyses to properly classify and identify the species of .

What is the difference between freshwater and marine mussels?
Marine and freshwater species of mussels are both farmed, though typically for different purposes. Mussels that are farmed specifically for food are mainly grown in marine environments, and freshwater species are typically used to create cultured pearls.

What is the life cycle of a freshwater mussel?
The freshwater mussel's life cycle begins when males release sperm into the water, and females store their laid eggs in gills called 'marsupia'. Through siphons, the female takes in sperm that fertilizes the egg, leading to the development of glochidia (mussel larvae).
Conservation biology of freshwater mussels
Species of bivalve
The duck mussel is a species of freshwater mussel, an aquatic bivalve mollusk in the family Unionidae, the river mussels.
One kind of freshwater mollusc
Freshwater bivalves are one kind of freshwater mollusc, along with freshwater snails. They are bivalves that live in fresh water as opposed to salt water, which is the main habitat type for bivalves.
Part of Earth's aquatic ecosystems
Freshwater ecosystems are a subset of Earth's aquatic ecosystems. They include lakes, ponds, rivers, streams, springs, bogs, and wetlands. They can be contrasted with marine ecosystems, which have a larger salt content. Freshwater habitats can be classified by different factors, including temperature, light penetration, nutrients, and vegetation. There are three basic types of freshwater ecosystems: Lentic, lotic and wetlands. Freshwater ecosystems contain 41% of the world's known fish species.
The freshwater pearl mussel is an endangered species of freshwater mussel
Species of mollusc
The freshwater pearl mussel is an endangered species of freshwater mussel, an aquatic bivalve mollusc in the family Margaritiferidae.
The zebra mussel is a small freshwater mussel
Species of bivalve
The zebra mussel is a small freshwater mussel. The species originates from the lakes of southern Russia and Ukraine, but has been accidentally introduced to numerous other areas and has become an invasive species in many countries worldwide. Since the 1980s, the species has invaded the Great Lakes, Hudson River, and Lake Travis.
