Bycatch Avoidance Programs

SMAST Bycatch Avoidance Program

SMAST is running the Bycatch Avoidance Program for yellowtail and windowpane flounder in fishing year 2015, including open area fishing grounds in Southern New England, Georges Bank, and the Great South Channel. 

The Bycatch Avoidance program uses near real-time communications with fishing vessels to determine the location of bycatch hotspots to assist scallopers harvest their target scallop allocation without triggering bycatch closures. The program was started in 2010 with the collaboration of the scallop fleet and currently there are over 250 participants using the hotspot information to avoid flounder bycatch.

The 2015 SMAST Bycatch Avoidance Program began on April 1, 2015.

River herring avoidance in the Atlantic herring and mackerel fisheries

Alewife in herring catch

The incidental catch of river herring by vessels targeting Atlantic herring and mackerel has become a concern for their conservation. Though the direct effect of this bycatch on river herring populations is unknown, managers have created river herring catch limits. If river herring catch limits are reached, large areas of the Atlantic herring fishery or the entire mackerel fishery would be closed.

This collaborative project between mid-water trawl fishermen , Rhode Island bottom trawl fishermen, the Massachusetts Division of Marine Fisheries, and SMAST seeks to reduce river herring and shad bycatch independent of management action; aiding in the effort to rebuild river herring and providing fishermen with a tool to avoid area closures.

Sampling catch of herring boat

The project involves increasing portside sampling , a near real-time information system on the location bycatch events, and testing if oceanographic features can be used to indicate areas with a high probability of bycatch. The project was started in 2010, with funding from the National Fish and Wildlife foundation. It is now sustained by The Nature Conservancy and the Atlantic herring Research Set Aside (RSA) program. 

Final Bottom Trawl - Winter 2015  

Bycatch classifcations were changed in 2015 to reflect river herring catch limits. HIGH bycatch events now relfect a rate at which river herring catch limits will be reached before Atlantic herring catch limits. This resulted in lowering the HIGH bycatch threshold for bottom trawl vessels from 5% to 1% and from 1.25% to 0.6% for mid-water trawl vessels.

Herring RSA Information: Through the Atlantic herring RSA program, SMAST aplied for and recieved 1,974 mt of Atlantic herring quota in 2014 and 2015 to generate funds for the river herring bycatch avoidance program. The 2015 RSA quota will be distributed to companies that agreed to be held to a higher standard while harvesting RSA quota and meet certain criteria of the river herring bycatch avoidance program. Download the Responsible Fishing Agreement. Funds generated by the harvest of herring RSA quota are also used to monitor the landings of these vessels when they return to port.
