^ Number of participants estimates are based on state and federal fisheries permit data.  The estimated number of participants is expressed in terms of the number of active participants in the fishery, when possible.  If this information is not available, the estimated number of vessels or persons licensed for a particular fishery is provided.  If no recent information is available on the number of participants, then the number from the most recent LOF is used.  NMFS acknowledges that, in some cases, these estimations may be inflating actual effort.  

*Observer coverage levels include the latest information reported in the most current final Stock Assessment Report (SAR)

Basis for Current Classification

There are no documented marine mammal interactions


“The Maine quahog fishery is active year round and is defined as the area north of 43 degrees 50 minutes north latitude to the Maine shore by Amendment 10 of the Surfclam and Ocean Quahog Fishery Management Plan...  Because of recent increases in the severity of toxic phytoplankton blooms, the ocean quahog fishing grounds have been restricted to a small area south of Addison, Maine defined by the Loran CTD’s  9960 X 25748, 9960 X 25715 and 9960 W 12210, 9960 W 12150”3

Gear Description

Water is pumped onto the sea floor to clear sand and  make target species more easily accessible and is then caught in dredge which is pulled over the floor.
