Changes in abundance and distribution of the Barents Sea long rough dab, hippoglossoides platessoides (Fabricius) during the period 1980- 1992
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 Russi...
