To whom it may concern, The photo-identification catalogue and status of the northern resident killer whale population in 2014 has recently been published as a Canadian Technical Report of Fisheries and Aquatic Sciences. It and the most recent Bigg’s killer whale photo-identification catalogue can be downloaded from the publications page at bckillerwhales.com Towers, J.R., Ellis, G.M. and Ford, J.K.B. 2015. Photo-identification catalogue and status of the northern resident killer whale population in 2014. Can. Tech. Rep. Fish. Aquat. Sci. 3139: iv + 75 p. Field studies of the life history and ecology of killer whale populations off Canada’s west coast have been conducted annually since 1973. These studies are based on the identification of individual whales from photographs of permanent, natural markings. In this report, we summarize abundance trends in the northern resident killer whale population between 1974 and 2014, and provide an updated photo-identification catalogue of individuals. In 2014, the northern resident population was composed of 290 whales. The population has grown at an average mean annual rate of 2.2% since 1974. Continued population monitoring by photo-identification is a key research activity in the recovery strategy for this threatened population. best regards, Jared Towers Cetacean Research Technician Cetacean Research Program Pacific Biological Station Fisheries and Oceans Canada Nanaimo BC, Canada 250-902-1779 jrtowers@gmail.com
