AFSC/RACE/MACE: Results of 2012 acoustic trawl survey Bogoslof DY1202

Description

Scientists from the Midwater Assessment and Conservation Engineering (MACE) program of the Alaska Fisheries Science Center (AFSC) Resource Assessment and Conservation Engineering (RACE) Division conducted an acoustic-trawl (AT) survey of walleye pollock in the southeastern Aleutian Basin near Bogoslof Island aboard the NOAA ship Oscar Dyson during 7-15 March, 2012. The survey was designed with two survey tracks, which covered 3,656 nmi2 of the CBS Convention Specific Area. The primary survey track was nearest to the Aleutian Islands and consisted of 35 north-south parallel transects spaced 3 nmi apart and the second survey track was located just north of the primary survey track, and consisted of 12 north-south parallel transects space 9 nmi apart. These second survey track was essentially northern extensions of the primary survey track, designed to observe whether walleye pollock were present in deeper water. The survey followed established AT methods as specified in NOAA protocols for fisheries acoustics surveys and related sampling.
