Abstract

Since the 1970’s, Steller sea lion (Eumetopias jubatus) populations have decreased in the western distinct population segment (DPS) but not in the eastern DPS despite historical culling of eastern stock. Competition for fish with fisheries has led to a nutrient lacking diet, affecting reproductive success and natality. Anthropogenic threats such as heavy metal contamination and chemical toxins can cause physiological damages, decreasing reproductive success. The use of the ocean for human gain, and disrespect of the ecosystems within it should be stopped from progressing into further destruction so that the ocean and the threated populations of Steller sea lions within it can recover.
