Intersex fish have been found in the Susquehanna River.
A federal scientist says intersex fish have been found in the Susquehanna River. The biologist says more than 90 percent of the adult male bass examined in the river in the past year had immature eggs cells in their sexual organs.
Intersex fish are believed to be the result of the hormones from birth control pills and other consumer and agricultural chemicals getting into water ways.
Intersex fish have been found nationwide, including in the Potomac River, another key tributary of the Chesapeake Bay.
