Results of Northern Shrimp Test Tows during 2014

The DMR contracted with a commercial shrimp trawler to conduct three short (mostly 12-15 minutes) shrimp tows on each of five days during January - March 2014.  The purpose of the project was to continue our time series of winter shrimp samples, and the determination of the timing of egg hatch.   The results are listed below.   Most of the tows were conducted off Pemaquid Point.
