Fraser's dolphin (Lagenodelphis hosei)

Knowledge of the distribution and relative abundance of odontocete cetaceans is important for helping to understand and potentially mitigate impacts of anthropogenic activities. We present small-boat survey and sighting data from 13 y (2000 through 2012) of field studies around the main Hawaiian Islands. We surveyed 84,758 km of trackline, with effort ranging from 3 to 11 y off each of the four different island areas. We had 2,018 sightings of odontocetes representing all 18 species known to exist in Hawai‘i.
