USGS research fishery biologist Micah Kieffer sutures an adult Atlantic sturgeon after implanting an acoustic transmitter in its abdomen as part of efforts by USGS Eastern Ecological Science Center and partners to better understand sturgeon movements in the Gulf of Maine. This project was funded by the U.S.
