Bycatch Avoidance Programs

SMAST Yellowtail Bycatch Avoidance Program

Capt. Chris Wright enters yellowtail bycatch information into Boatracs reporting macro onboard the F/V Huntress

SMAST expanded the Bycatch Avoidance Program in fishing year 2014 to include open area fishing grounds in Southern New England and on Georges Bank, and include windowpane flounder in addition to yellowtail flounder bycatch advisories.  We created new reporting grids to cover the Southern New England Open Area, the Northern Open Area and Southern Open Area of Georges Bank and the scallop rotational access areas.  

The Georges Bank yellowtail flounder allocation to the scallop fishery was reduced by over 40% in 2014 to 51 metric tons (~112,000 pounds).  Exceeding the Annual Catch Limits can result in costly time/area closures of prime scallop fishing grounds.  

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 with the collaboration of the scallop fleet and currently there are 243 participants using the hotspot information to avoid yellowtail bycatch.

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 could 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 RSA program.
