Bycatching by ocean fishermen may imperil river herring stocks
Alewife species of river herring.

“River herring, both the blueback and alewife species found in Rhode Island, are diadromous fish, meaning they spawn in freshwater but live their adult lives in the ocean.
“A foundational species, river herring sit at the bottom of the aquatic food chain, helping to feed larger animals like striped bass and osprey. In past generations, they swam up many New England rivers in the millions, providing a source of food and income for locals; herring are considered an important food in Narragansett culture.
“Efforts to improve their spawning habitat have brought the fish back to environments they haven’t lived in since before the Industrial Revolution. However, experts and stakeholders who spoke with ecoRI News said that what’s happening to river herring when they’re in the ocean has a huge and potentially negative impact on their survival: bycatch.’’
