How do mussels reproduce?

Freshwater mussel reproduction and the fish- mussel relationship can be summarized in a few points: Female mussels fertilize their eggs with sperm from a male and develop larvae called “glochidia”. Once mature, females may release their glochidia into the water or even attract a fish to swim close with a lure.
