This paper presents the results from a joint survey with two research vessels in July 1985. Total estimates of abundance (N x 10-9 ), were: Norway pout 56, haddock 52, whiting 66 and cod 4. Comparisons are made with a similar survey in July 1984 and with some recruitment estimates from other surveys.
