BALTIMORE (AP) _ University of Maryland scientists say they've found intersex fish on the Eastern Shore and in Delaware.
And scientists have a new theory about the source of the condition: They believe it can be traced to the poultry manure that's used as fertilizer in the region.
Scientists say they found male largemouth bass carrying eggs in six lakes and ponds on the Delmarva Peninsula sampled over the past two years. Intersex fish have also been found in the Potomac and Susquehanna rivers.
Researchers say the intersex condition of the fish on the Shore is not as severe, but it appears to be just as widespread.
Intersex fish are a concern because they could be indicators of contaminants in the water.
The lakes and ponds checked were in Queen Anne's and Caroline counties in Maryland and in Kent and Sussex counties in Delaware.
