【 摘 要 】

Gametogenic development of Magnonaias nervosa (Bivalvia: Unionidae) was examined monthly from April 1986 to March 1987 in Navigation Pool 10 of the Upper Mississippi River. This species attains sexual maturity at a shell height of about 68 mm and at an age of eight years. M.nervosa is a late tachytictic breeder that releases glochidia from September to November as ambient river temperature declines.
