1. Further analysis of spatial patterns of benthic invertebrate habitats from fishery bycatch in the Ross Sea region

   presence of VME taxa bycatch are identifiable, as are several areas of dense fishing effort with no ... evidence of VME taxa. Identifiable sponge and/or gorgonian habitats occurred at a typical scale of 10-30 km ... , but were at larger scales. Spatial analysis of these data allows the detectability of prevalent taxa ... to be estimated, along with changes in catch rate at different levels of observed bycatch. Results ...
