Question: How Do Mussels Mate?

How do mussels reproduce?

Freshwater mussel reproduction and the fish- mussel relationship can be summarized in a few points:

How often do freshwater mussels reproduce?

It may take several years (2-9) before juveniles mature and can reproduce as an adult. Adults may live 60 – 70 years if conditions are right. However, studies have documented that it is not uncommon for some species of mussels to successfully reproduce only once out of seven or more years.
