Photo-identification catalogue and status of the northern resident killer whale population in 2014 / by J.R. Towers, G.M. Ellis and J.K.B. Ford.: Fs97-6/3139E-PDF
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.
