Program Aims to Restore Shad in Maryland
By KRISTEN WYATT
JARRETTSVILLE, Md. – One day they’ll be 2 feet long with silver scales, but for the moment these American shad are less than a half-inch long, barely visible in water except for tiny black dots for eyes.
They’ve been raised from larvae over the last two weeks by children from five Maryland schools as part of an American shad restoration project that takes shad from classroom aquarium tanks to a stream that leads to the Chesapeake Bay.
Tuesday was graduation day for the fish.
Many of the 5,000 shad sent to the science classrooms had already died – an unavoidable occurrence, biologists said – and even fewer will survive to adulthood.
The lucky ones will grow to about 20 inches, migrating south to the Susquehanna River and then the Chesapeake Bay.
Then they’ll spend about three to five years in the Atlantic Ocean before returning to this same Harford County stream to spawn.
“They’re littler than I thought,” said 13-year-old Ryan Burton, a seventh grader at North Harford Middle School who helped raise that school’s shad in his science class.
