52558 Document Published / External 30990 PSD- Cetacean Research Program (CRP) Publications Portfolio Project 2018-06 Marine mammal interactions (i.e., hookings and entanglements) with the Hawaii and American Samoa longline fisheries observed during 2015-2016 were compiled, and the number of marine mammal deaths, serious injuries, and non-serious injuries by fishery, species, and management area were assessed. These values are used to compute the mortality and serious injury estimates included in the stock assessment reports of stocks impacted by these fisheries. Injury determinations were made using a nationally standardized process and established criteria for distinguishing serious from non-serious injuries (National Marine Fisheries Service, 2012). In the Hawaii deep-set fishery, 22 marine mammal interactions were observed from 2015 to 2016; most involved false killer whales (59.1%), resulted in death or serious injury (68.1%), and occurred outside the U.S. exclusive economic zone (EEZ) (81.8%). In the Hawaii shallow-set fishery, 18 marine mammal interactions were observed from 2015 to 2016; most involved Risso's dolphins (27.8%), resulted in death or serious injury (77.8%), and occurred outside the U.S. EEZ (100.0%). In the American Samoa deep-set fishery, 6 marine mammal interactions were observed from 2015 to 2016; most involved false killer whales (66.7%), resulted in death or serious injury (83.3%), and occurred within the U.S. EEZ (100.0%).
