Analysis of scat samples from animals is a non‐invasive technique that can provide important data on animal diet, hormone levels, microbiome, and genetics. The use of a trained Conservation Canine (K9) to detect marine mammal scat at sea has been proven to be useful in the Pacific Northwest with Southern Resident Killer Whales. If this method were refined in the future, analysis of scat samples from animals that had been in close proximity to training and testing events may provide important data on stress responses in the animal during the 24 hours preceding the collection, and the potential consequences of that response. In order to explore the viability of this method in Hawaii, the Navy invested in a pilot study to determine if a K9 could be successfully trained to detect and ‘direct’ boat drivers – via changes in behavior – to the scat of three species of marine mammals (G. macrorhynchus, K. breviceps, and P. crassidens).
A K9 was successfully trained to detect and ‘direct’ boat drivers – via changes in behavior – to the scat of three species of marine mammals (G. macrorhynchus, K. breviceps, and P. crassidens). This was conducted in two phases, beginning with detecting fecal material samples from stranded animals on land and then progressing to training sessions aboard a small boat off Oahu.
The K9 was successfully trained to detect and ‘direct’ boat drivers – via changes in behavior – to the scat of three species of marine mammals (G. macrorhynchus, K. breviceps, and P. crassidens) during training on land an on a boat. During a trial at sea, a group of pilot whales was located with human visual observers and the K9 successfully indicated that scat was detected.
It is difficult to draw many conclusions from one encounter with wild cetaceans during this pilot study. However, using conservation K9s for marine mammal scat collection in Hawaii appears to be a promising additional tool to complement other methods of obtaining samples for hormone levels, microbiome, and genetics.

Analysis of scat samples from animals is a non‐invasive technique that can provide important data on animal diet, hormone levels, microbiome, and genetics. The use of a trained Conservation Canine (K9) to detect marine mammal scat at sea has been proven to be useful in the Pacific Northwest with Southern Resident Killer Whales (Lundin et al. 2016) and in other unpublished reports and media, but until now, had not been documented in Hawaii. In order to explore the viability of this method in Hawaii, the Navy invested in a pilot study, where the K9 was successfully trained to detect and ‘direct’ boat drivers – via changes in behavior – to the scat of three species of marine mammals (G. macrorynchus, K. breviceps, and P. crassidens).
