Spawning Sequence of Largemouth Bass, Bluegill, and Gizzard Shad

The effect of body size on the temporal spawning sequence of female largemouth bass (Micropterus salmoides), bluegill (Lepomis macrochirus), and gizzard shad (Dorosoma cepedianum) was examined in 2 Mississippi reservoirs by monitoring gonadal development through portions of the spawning seasons. Largemouth bass began spawning in late March when water temperature was near 15° C, gizzard shad in about mid-April at temperatures nearing 17° C, and bluegill in late April when temperatures reached 21° C; however, spawning seasons of the 3 species overlapped.
