Pre-Season Shrimp Tows, Stonington, Maine, January 13, 2013

Three shrimp trawlers from Maine (from South Bristol, Stonington, and Sebasco) and one from New Hampshire made some experimental pre-season shrimp tows for one day during the week of January 13, 2013.  All data from the Stonington trip are listed below.

The Stonington boat averaged 124 pounds of shrimp per hour.  Its best tow was 256 pounds per hour.  Depths ranged from 30 to 48 fathoms, with the highest catch rate at about 40 fa. (see tow 2 below).  Count per pound was consistently about 34.  Most shrimp were still carrying eggs (see graph at bottom).
