Abstract Increasing production of salmon open-net pen culture has raised concerns about the negative impact of this aquaculture technology on the marine environment. In British Columbia (BC), Canada, benthic deposition of organic nutrients (faeces and waste feed) is identified as a potential source of localized environmental degradation from salmon farming. In this paper, we develop a marginal damage cost function to provide a quantitative monetary measure for potential environmental impacts of simulated salmon farms, representative of typical BC net pen sites. The development of the functions is done by integrating the outputs of a discrete choice experiment (DCE) with the results of an organic deposition model (NewDEPOMOD). The resulting relationships can be used to find efficient policies and sustainable operation strategies that balance salmon production with the external cost to the marine environment.

加拿大不列颠哥伦比亚省露天围栏鲑鱼养殖场颗粒有机碳负荷的边际损害成本函数

摘要 鲑鱼露天围栏养殖产量的增加引起了人们对这种水产养殖技术对海洋环境的负面影响的担忧。在加拿大不列颠哥伦比亚省 (BC)，有机营养物（粪便和废物饲料）的底栖沉积被确定为鲑鱼养殖局部环境退化的潜在来源。在本文中，我们开发了一个边际损害成本函数，为模拟鲑鱼养殖场的潜在环境影响提供量化的货币衡量标准，该养殖场代表了典型的 BC 网围网点。函数的开发是通过将离散选择实验 (DCE) 的输出与有机沉积模型 (NewDEPOMOD) 的结果相结合来完成的。
