Risk Assessments and Approaches for Evaluating Myxozoan Disease Impacts

  • Chapter
  • First Online:
Myxozoan Evolution, Ecology and Development

Abstract

Risk assessments are increasingly being used as tools to examine the possibility and consequences of transboundary introductions of pathogens and parasites of important aquaculture species. Developing these tools for myxozoan parasites is complicated by their two-host life cycles and our lack of basic data for many parameters. The distributions of many myxozoans are undocumented, techniques used for detection of myxozoan may vary in sensitivity and specificity, and often, the invertebrate host and its ecological requirements are poorly understood. Risk assessments for myxozoans have been performed for a variety of reasons and incorporate different geographic scopes and management questions. In this chapter, we review the general components of a risk assessment, discuss specific data requirements for myxozoan risk assessments, and provide examples of myxozoan risk assessments in relation to importation of food fish, emerging aquaculture species and wild fisheries, and pathogen transmission from aquaculture to wild fish.
