Abundance and biomass of long rough dab in tha Barents Sea and
adjacent waters were assessed from bottom trawl survey data from
research surveys by Norway and Russia, during the period 1980-
1992. Although there was no directed fishery for this species,
with only a 1000-6000 ton bycatch by the Russian fleet, the
population abundance and biomass were reduced by 50% of the long
term average during 1986 to 1988. Subsequently the population
began to increase to pre-1985 levels. We suggest that these
fluctuations reflect changes in availability of the population to
the survey gear, however the mechanism responsible is not clear.
