Are Fishermen Observing Changes in River Herring Runs in Downeast Maine?

In recent years much attention has been given to the conservation and management of alewives (Alosa pseudoharengus) and blueback herring (A. aestivalis), collectively known as river herring. Centuries of habitat destruction and fishing pressure have taken their toll on these ecologically and economically important species. Recognizing that fisheries independent data for assessing changes in abundance are limited, we are collecting observational data and insights from river herring harvesters in Downeast Maine to fill this data gap. Harvesters' observations of changes in abundance, run timing, distribution, size composition, species composition, and other biological parameters can help improve our understanding of the biology, behavior, and population status of these species in response to changes in habitat availability, fisheries management, and climate. We also aim to document harvesters' perspectives on the cultural importance of river herring in this fishing-dependent region. Downeast Mainers have harvested river herring for centuries and these species currently play an important role in Maine’s economy as a preferred bait in the lobster and other commercial fisheries. Results are pending at the time of abstract submission but by August 2014 we will have collected and documented a wealth of fishermen’s knowledge that is highly relevant to restoration efforts and management.
