Killer Whale Stranding Reports

New!
Killer whales (Orcinus orca) are widely distributed throughout the world’s oceans, yet little has been documented about their stranding patterns. Knowledge of stranding patterns improves our ability to examine and sample carcasses and provides a foundation for understanding killer whale natural history, diet, reproduction, anthropogenic stressors, emerging diseases, and patterns of unusual mortality. MICHELLE M. BARBIERI et al
"The U.S. National Marine Fisheries Service (2008) mandated improved killer whale stranding response as part of a comprehensive effort to better define causes of killer whale mortality and inform conservation efforts in the case of the Southern Resident killer whale distinct population segment (DPS) in the eastern North Pacific."
"Since 2004 there has been a 32% increase in the number of complete necropsies done on killer whales. The development of a killer whale necropsy and stranding response protocol (Raverty and Gaydos 2004), combined with U.S. federal interest and financial resources facilitated this improved response to killer whale strandings."
"The historical data obtained in this study were used to describe monthly and seasonal trends in North Pacific killer whale strandings to guide stranding response efforts and resource allocation. While these data are likely incomplete, they represent the best current information on killer whale strandings in the North Pacific and illustrate the importance of continued time and resource allocation to investigate threats to free-ranging killer whales."
