Pride of the South: Risk Analysis for Marine Biosecurity in Fiordland

Abstract

This paper describes a model used to assess alternative scenarios for managing the marine biosecurity risk to Fiordland from vessel traffic. Scenarios are assessed in terms of risk reduction per dollar spent. To keep the analysis manageable, we focus on vessel risks from hull fouling, as this is considered the primary pathway of vessel-related spread. Our analysis includes evaluation of the costs and benefits of different types of vector treatment as well as the possibility of continued vessel monitoring and control of pest populations in Bluff Harbour to reduce the risk of vector infection.Fiordland, marine biosecurity, risk reduction, benefit cost analysis, management options, Bluff, Agricultural and Food Policy, Environmental Economics and Policy, Food Security and Poverty, Health Economics and Policy, Land Economics/Use, Livestock Production/Industries, Research Methods/ Statistical Methods,
