Using acoustic echo counting to estimate grenadier abundance in the Ross Sea (SSRU88.1I)
Abstract: Grenadiers (Macrourus spp.) are the main bycatch species in the exploratory longline ... fishery for toothfish in the Ross Sea. Previous studies concluded that acoustics methods could be used to ... index the relative abundance of grenadiers and be useful for exploring spatial distribution. Automated ... longline catches of grenadiers and toothfish. Single targets were most abundant within 250 m of the bottom ...
