Abstract
We provide the first records of threadfin shad (Dorosoma petenense) in the Delaware River estuary, and the first records of this species in the Delaware River basin since they were stocked in a pond but unable to over-winter in 1977. We collected threadfin shad by boat electrofishing on four separate sampling events and in two tributaries to the Delaware River from August 5, 2022, to August 30, 2023. We briefly speculate on the potential impacts of the species, provide mechanisms to explain their occurrence, and discuss our findings in the context of climate warming and range expansion. These records provide the northernmost account of threadfin shad on the eastern seaboard of North America, excluding a questionable record from the Atlantic Ocean near Nova Scotia in November 1998.
