Abstract

Scientists from the Midwater Assessment and Conservation Engineering (MACE) Program of the Alaska Fisheries Science Center's (AFSC) Resource Assessment and Conservation Engineering (RACE) Division conducted an acoustic-trawl (AT) stock assessment survey of the Shumagin Islands and Sanak. The Shumagin Islands survey was conducted 12-15 Feb., beginning in Shumagin Trough, continuing through Stepovak Bay, Renshaw, Unga Strait, Korovin Strait and ending in West Nagai Strait. The Sanak Trough area survey was conducted 15-16 Feb., followed by the survey of Morzhovoi Bay on 16 Feb.

Lineage

Lineage Statement:

Acoustic data were recorded at the five split-beam frequencies using ER60 software and, as a backup, acoustic telegram data were logged with Myriax EchoLog 500 software. Acoustic measurements were collected from 16 m below the sea surface to within 0.5 m of the sounder-detected bottom or a maximum of 1,000 m in deep water. Data were analyzed using Myriax Echoview post-processing software. See National Marine Fisheries Service (NMFS) 2013.
