Accessed July 17, 2024 at https://animaldiversity.org/accounts/Morone_saxatilis/ Comments: For the first 2 years of life, striped bass move in small groups and tends not to migrate. Once large enough, they congregate in larger schools and begin following annual migrations patterns. Striped bass an perform upriver spawning migration, which lasts from late winter to early spring, and coastal migration, which is not associated with spawning. Although this species is generally social, females exceeding 30 pounds have been found as solitary individuals. |
Reproductive frequency (?) | Iteroparous References (not structured): Setzler-Hamilton, E. M. 1980. Synopsis of biological data on striped bass, Morone saxatilis (Walbaum) (No. 121). Department of Commerce, National Oceanic and Atmopsheric Administration, National Marine Fisheries Service. |
Reproductive type (?) | Sexual References: Setzler-Hamilton, E. M. 1980. Synopsis of biological data on striped bass, Morone saxatilis (Walbaum) (No. 121). Department of Commerce, National Oceanic and Atmopsheric Administration, National Marine Fisheries Service. Comments: Morone saxatilis is polyandrous. A group of 7 to 8 males surround a single larger female, and once surrounded, males bump the female to the waters surface. This act is often referred to as “rock fights,” due to the splashing that occurs on the surface of the water. Once at the surface, males continue bumping the female until she releases her eggs into the water. Once the eggs are discharged into the water, males release their sperm. |
Developmental trait (?) | Spawning References: Setzler-Hamilton, E. M. 1980. Synopsis of biological data on striped bass, Morone saxatilis (Walbaum) (No. 121). Department of Commerce, National Oceanic and Atmopsheric Administration, National Marine Fisheries Service. Gervasi, C. L. 2015. The reproductive biology of striped bass (Morone saxatilis) in Chesapeake Bay. Comments: Striped bass begin spawning when temperatures warm to about 18 degrees C. They tend to spawn in rivers and in brackish estuaries. Once fertilized, embryos drift in the current for 1.5 to 3 days. Female can release between 500,000 and 3 million eggs during a single spawning event; however, less than one percent of embryos survive for more than a couple of months after hatching. Male striped bass typically reach sexual maturity at 2 to 3 years of age, and females reach sexual maturity at 5 to 6 years of age. |
Characteristic feeding method / Life stage (?) |
References (not structured): Gervasi, C. L. 2015. The reproductive biology of striped bass (Morone saxatilis) in Chesapeake Bay. Comments: M. saxatilis is a top predator and a vital component of marine and estuarine food webs. Age-0 fish feed primarily on invertebrates, predominantly polychaetes, gammarid, and mysid shrimp. By age 2, the Striped Bass diet shifts to primarily schooling fishes (i.e., clupeids), crustaceans, and polychaetes, though benthic fishes also contribute to the diet. As larvae feed on zooplankton, and as juveniles they mostly feed on insect larvae, small crustaceans, mayflies, and larval fish. |

Habitat modifying ability potential (?) | Keystone species Comments: Striped bass are important predators on Atlantic menhaden and help maintain prey populations at sustainable levels. Major parasites of striped bass include copepods , tapeworms, cestode worms, protists, myxozoans , roundworms, and spiny-headed worms. |

Comments: Throughout its range, Striped Bass occupies many habitats, including bays, surf zones, marshes, shoals, and large rivers. Because of its mobility, size, and use of diverse habitat types, Striped Bass consume a wide variety of prey. |
