Understanding the impact of a changing climate on interactions between Pacific sardine and Pacific herring populations in British Columbia

The population of sardines along the Pacific coast increased dramatically in the last few decades, while the west coast of Vancouver Island population of Pacific herring has been declining. The herring population may be impacted by competition with sardines for food during the summer months in common feeding grounds off Vancouver Island. Using fish distribution, diet composition, and ocean conditions, this project aims to study how competition potentially affects herring. The results of this study will provide the information necessary to explore the effect of future climate change predictions on habitat overlap and the potential for competition between these species.
