Abstract:
... Aquaculture governance can be challenging as a number of stakeholders have different objectives and visions for the industry. A license is an important tool in ensuring an orderly development of an industry, providing rights as well as obligations. However, the constraints imposed by a license can also prevent desirable activities. In the Norwegian aquaculture industry this has been addressed by c ...
