Alaska Fisheries Science Center (U.S.)

Scientists from the Midwater Assessment and Conservation Engineering Program of the Alaska Fisheries Science Center (AFSC) have conducted echo integration-trawl (EIT) surveys in the southeastern Aleutian Basin near Bogoslof Island to estimate midwater pollock (Theragra chalcogramma) distribution and abundance annually since 1988, with the exception of 1990. The biomass estimate for pollock within the Central Bering Sea (CBS) Convention Specific Area obtained during these surveys provide an index of abundance for the Aleutian Basin pollock stock (Honkalehto and Williamson, 1995). The results presented here are from the echo integration-trawl (EIT) survey carried out 8-14 March 2003 aboard the NOAA ship Miller Freeman, Cruise MF2003-04.
