3. The relative by-catches of taxa associated with vulnerable marine ecosystems by autolines and Spanish longlines

   Abstract:  We reanalyzed data collected by the longline fishery in Subarea 88.1 to compare the ... with each gear type, we attributed this difference to a difference in the rate at which VME taxa drop ... greater than Spanish bycatch at all depths represented in our data. Limiting the use of Autolines, which ... are in more intimate contact with the sea floor than Spanish longlines, may decrease bycatches of VME ...
