No binding international instruments are in place to regulate the introduction or release of non-native species to freshwater ecosystems. However, the Convention on Biological Diversity (CBD) requires parties, as is possible and appropriate, to prevent the introduction of, and to control or eradicate, alien species that threaten native ecosystems, habitats or species, and recommends the use of risk assessment to justify actions taken against such threats. International trade and transport are major pathways for the spread of non-native species. Where sufficient risk can be scientifically demonstrated, countries may impose national measures to prevent their introduction. Guidelines for pest risk assessment, and the development of national measures to protect plant life and health, have been issued by the European Plant Protection Organisation (EPPO) under the International Plant Pest Convention (IPPC), a standard-setting body recognized under the World Trade Organisation 1995 Agreement on the Application of Sanitary and Phytosanitary Measures (SPS Agreement). Whilst not directly relevant to freshwater fish pests, these standards provide a useful guide for the development of independent risk assessment frameworks for other taxonomic groups. Using the EPPO protocol as a template, we present a conceptual framework for a Pest Fish Risk Assessment (PFRA). This semi-quantitative protocol, developed specifically for the UK but potentially applicable elsewhere, is designed to provide a comprehensive, transparent, assessment of the overall risk posed by a non-native freshwater fish species. The framework encourages identification of pathways for analysis and management, and aims to inform policy decisions relating to pre-border, border and post-border procedures and related legislation.
