Bivalve molluscs can be categorized based on their sexual reproductive system into those with gonochorism and those with hermaphroditism, as in other organisms with sexual reproduction.
They may exhibit gonochorism (fixed separate sexes), simultaneous (or synchronous) or sequential hermaphroditism.
Evidence of gonochorism in a grouper, Mycteroperca rosacea, from the Gulf of California, Mexico.
The ovaries of the smooth lumpsucker are characterized by the absence of sperm in all gonads, indicating gonochorism, oviparity, and external fertilization (Devlin and Nagahama, 2002).
Fish species have complex patterns of sex determination which range from hermaphroditism, with individuals presenting both female and male gonads, and gonochorism, where each individual presents only female or male gonads, to TSD.

Abstract.--The sex allocation pattern of various populations of spotted sand bass are thought to vary from functional gonochorism to strict protogyny.
The sexes are separate (gonochorism) in sexual populations, hence self-fertilization is ruled out as a mode of uniparental reproduction.
However, increasing evidence indicates that some species are diandric hermaphrodites, such as the catface grouper (Epinephelus andersoni) (Fennessy and Sadovy, 2002), and Sadovy and Colin (1995) confirmed gonochorism, with the potential for protogynous sex change, in the Nassau grouper (Epinephelus striatus).
