Years ago, it was said that rivers would “turn silver” during the spring due to the millions of river herring that migrated upstream to spawn. These small fish are “diadromous” - meaning they spend part of their life cycle in saltwater and part in freshwater. River herring, which refer to Alewife and Blueback herring, and American eel are among the few small diadromous fish found in Long Island streams and rivers, and they play an important role in supporting the local ecosystem. Unfortunately, their numbers have been reduced due to dams and culverts that block their journey upstream. To address this issue, the Long Island Sound Study, the Peconic Estuary Program, the South Shore Estuary Reserve, and the Seatuck Environmental Association work together every year to host the Annual River Herring and American Eel Survey.
In this webinar, experts from all four programs will discuss how data from this survey effort are used in the local management of streams and rivers, and how people can get involved in this monitoring effort. The webinar will also include a training per region to familiarize participants with the streams that need monitoring near them.
