While highly successful in terms of profitable seafood production, salmon (Salmo salar) aquaculture may also be a source of potential negative environmental externalities. In an attempt to address these challenges through supporting the development of new technology, the Norwegian government has introduced a new class of aquaculture licenses labeled as development licenses. As a result, new technological solutions were proposed to reduce negative externalities through (1) expansion to open ocean areas not yet used for aquaculture and (2) reduced emissions from inshore production systems. This paper presents an analysis of the technological concepts proposed in applications for development licenses. The applications for development licenses provide a unique perspective on what technological directions existing marine aquaculture companies envisage that marine aquaculture may take in the future. The analysis indicates that units will become larger and stronger, as well as being specially designed to suit a variety of environments, creating a more heterogeneous industry. Large offshore structures such as semi-submersible platforms and other strong, rigid structures with permeable enclosures (nets) have been particularly successful in this application process, receiving relatively many development licenses. In sheltered fjord areas, many concepts involving closed enclosures (bags and tanks) have been suggested and awarded licenses.

虽然在有利可图的海鲜生产方面非常成功，但鲑鱼 ( Salmo salar) 水产养殖也可能是潜在的负面环境外部因素的来源。为了通过支持新技术的开发来应对这些挑战，挪威政府引入了一种新的水产养殖许可证，称为开发许可证。因此，提出了新的技术解决方案，通过 (1) 扩展到尚未用于水产养殖的开阔海域和 (2) 减少近海生产系统的排放来减少负外部性。本文对开发许可证申请中提出的技术概念进行了分析。开发许可证的申请为现有海水养殖公司设想的海水养殖未来可能采用的技术方向提供了独特的视角。分析表明，单位将变得更大、更强，以及为适应各种环境而专门设计的，从而创造一个更加多样化的行业。大型海上结构，如半潜式平台和其他具有可渗透外壳（网）的坚固、刚性结构，在这一应用过程中特别成功，获得了相对较多的开发许可证。在有遮蔽的峡湾地区，许多涉及封闭外壳（袋子和水箱）的概念被提出并获得了许可。具有可渗透外壳（网）的刚性结构在此应用过程中特别成功，获得了相对较多的开发许可。在有遮蔽的峡湾地区，许多涉及封闭外壳（袋子和水箱）的概念被提出并获得了许可。具有可渗透外壳（网）的刚性结构在此应用过程中特别成功，获得了相对较多的开发许可。在有遮蔽的峡湾地区，许多涉及封闭外壳（袋子和水箱）的概念被提出并获得了许可。
