This Chapter discusses One Ocean which is a not-for-profit corporation that was created in 2002 as a liaison for the provincial fishing and petroleum sectors. It details the efforts, first promoted by Canada, to get countries with strong fishing traditions to practice good ecology while exploring petroleum resources. Yet the Newfoundland and Labrador areas of Canada have found creative ways to share the sea between two major stakeholders: the fishing and petroleum industries. In addition to the centralized fishing industry, the government intervention in the fishing/petroleum co-existence is much lower in Newfoundland than in most other offshore oil operations. This industry sectors work together to harvest resources from the sea, and an organization called One Ocean facilitates this collaboration. There are many other ways that the One Ocean organization has worked to facilitate communication between the various stakeholders. The One Ocean model has enabled the fishing and oil industries to communicate and address concerns before they become problematic.
