Description:
The fourth triennial bottom trawl survey of western and central Gulf of Alaska groundfish resources was conducted by the Resource Assessment and Conservation Engineering Division (RACE) of the Alaska Fisheries Science Center (AFSC), Seattle, Washington from June through Septernber 1993. Previous surveys in this series hrere conducted in 1984, 1987 and 1990. The primary focus of the triennial groundfish surveys is to continue a standardized tirne series designed to assess, describe and monitor the distribution, abundance, and biological condition of various Gulf of Alaska groundfish stocks. Two chartered survey vessels, the F/V's Alsea and Argosy were rigged for survey operations on June 2-3 and departed Dutch Harbor on June 4. Scheduled port calls hrere rnade by both vessels on June 24 in Sand Point, and on July 16 at Kodiak. The Alsea broke its propeller shaft on August 6 and was towed to Seward on August 7 by the Argosy, for repairs. The Argosy departed Seward August 8 and completed its assigned survey stations, arriving in Kodiak on August 23. Due to the prolonged period anticipated to return the Alsea to service, the contractor provided the F/V Progress to complete the charter. The Progress departed Seward August 16, completed the unfinished Alsea stations and arrived in Kodiak on September 8. Almost aII of the 748 pre-selected survey stations nere visited but not all sites were sampled, primarily because of unsuitable botton conditions. Successful trawls ranging in depth from 20 to 513 m were achieved at 623 of the 674 stations attempted, an increase of 23% over the 508 stations completed during the 1990 survey (Figure 1). A total of 109 fish species were identified in survey catches. In addition to the groundfish species, catches also contained representatives from numerous invertebrate orders.
