* » Abstract |
Prior to 2015, the occurrence of humpback whales (Megaptera novaeangliae) in the Mariana Islands, located in the western North Pacific Ocean (WNP), was known from whaling records, incidental sightings, passive acoustic recordings and a sighting during a shipboard cetacean survey of the Marianas in 2007. It is not clear whether humpback whales use the Marianas as a wintering (breeding and calving) area or as a corridor from another wintering area(s) to their summertime feeding area(s), which are also unknown. To better understand the population identity of humpback whales in the Marianas, the Pacific Islands Fisheries Science Center's Cetacean Research Program partnered with the U.S. Navy to conduct small-boat photo-identification and genetic monitoring surveys for humpback whales off islands in the southern portion of the Mariana Archipelago during February-March 2015 and March 2016. A total of nine different mother-calf pairs and four non-calf whales were encountered during the 2015- 2016 surveys. Three fluke photo-identification images and nine biopsy samples were collected from these 22 individuals. Comparisons of the three fluke images to those of five humpback whales seen off the Marianas during the 2007 ship survey resulted in a match of a female with a calf in 2016. Comparisons with other WNP humpback whale catalogs and genetic analyses of the collected biopsy samples are ongoing and will be reported as results become available. |
