Long‐term predator diet studies are powerful ecosystem monitoring tools, as has been illustrated by the use of seabird diets to assess the response of forage fish communities to changing ocean conditions (Thayer et al. 2008). In British Columbia, Chinook Oncorhynchus tshawytscha and Coho Salmon O. kisutch are good candidates for a long‐term predator diet study, due to their ubiquity in coastal waters and the diversity of their diets.

长期掠食者饮食研究是强大的生态系统监测工具，海鸟饮食用于评估饲草鱼群落对变化的海洋条件的反应已证明了这一点（Thayer等人，2008）。在不列颠哥伦比亚省，由于在沿海水域无处不在且饮食结构多样，奇努克（Chinook Oncorhynchus tshawytscha）和Coho Salmon O. kisutch很适合长期捕食者饮食研究。
