The purpose of my study is to examine seasonal growth and food intake of Steller sea lions, Eumetopias jubatus, from captive animal records. Our current understanding of food intake is limited to one bioenergetic model which was based on growth data from wild animals collected mainly in the summer, reducing our understanding of seasonality. I will use a large, captive-animal data set to quantify Steller sea lion growth and energetic intake, and determine seasonal patterns that may be present in these large, sexually dimorphic animals. Also, I will examine how these patterns are influenced by life history stages such as weaning and reproduction, and to environmental conditions such as temperature. This study will help quantify and understand these key elements of their biology, and will be extremely useful in the continuing study and management of the endangered western population of Steller sea lions.
