This report examines survey technologies, with a focus on towed camera systems (TCSs), and modeling techniques which can increase nonindigenous species (NIS) detection and sampling efficiency in deepwater habitats of Northwestern Hawaiian Islands (NWHI); thus filling a critical data gap in present datasets. A pilot study conducted in 2008 at French Frigate Shoals and Brooks Banks was used to investigate the application of TCSs for surveying NIS in habitats deeper than 40 m. Cost and data quality were assessed. Over 100 hours of video was collected, in which 124 sightings of NIS were made among benthic habitats from 20 to 250 m. Most sightings were of a single cosmopolitan species, Lutjanus kasmira, but Cephalopholis argus, and Lutjanus fulvus, were also detected.
