    • Shrimp Survey Data

    Metadata Updated: March 8, 2024

    The Northern Shrimp Survey was initiated in 1983 by the Atlantic States Marine Fisheries Commission (ASMFC) and monitors the relative abundance (number of shrimp), biomass (weight of shrimp), and composition of the northern shrimp stock throughout the Gulf of Maine. The data give an understanding of year class strength and sex stage and maturity of shrimp in the population. The survey focuses its efforts in offshore waters (in depths greater than 50 meters) and is timed to sample both males and females during the summer when they are expected to be offshore. The data it collects forms the basis of the annual northern shrimp assessment, which in turn, is used by fishery managers from Maine, New Hampshire and Massachusetts to set each year’s fishing regulations.

    Lineage Vessel sensor data are collected electronically using SCS. Station, catch and biological data were collected manually using paper logs until 2004. At the completion of each cruise leg, the logs were keypunched and data audited extensively prior to being released. Starting in 2004, FSCS 1.0 was implemented to electronically capture station, catch and biological data. The electronic data collection system was upgraded to FSCS 2.0 in 2012. Data are subject to extensive audits prior to being released.
