"The purpose of this report is to provide information to the U.S. fishing industry and other interested parties on catch rates and average lengths of commercially important groundfish sampled during a groundfish assessment survey conducted in the eastern Bering Sea in the summer of 2005. The survey was conducted by the Resource Assessment and Conservation Engineering (RACE) Division of the Alaska Fisheries Science Center (AFSC) during the period from 30 May to 25 July. This report briefly describes survey methods and contains figures illustrating the distribution, relative abundance, and size composition of commercially important species of groundfish. Species included are walleye pollock (Theragra chalcogramma), Pacific cod (Gadus macrocephalus), yellowfin sole (Limanda asper), rock sole (Lepidopsetta polyxystra), flathead sole (Hippoglossoides elassodon and H. robustus), Alaska plaice (Pleuronectes quadrituberculatus), arrowtooth flounder (Atheresthes stomias and A. evermanni), and Greenland turbot (Reinhardtius hippoglossoides). An appendix to the report presents detailed position and catch data for each station fished. A similar report for species of crab is being prepared by personnel of the Shellfish Assessment Program, RACE Division of the Kodiak Laboratory of the AFSC. Copies are available upon request from L. Rugolo (NOAA/NMFS/AFSC, P.O.Box 1638, Kodiak, AK 99615). Online information about crab species from the trawl survey can be found at the following web address: http://www.afsc.noaa.gov/kodiak/shellfish/crabebs/crabsurvey.htm. "--Introd.
