Download Treatments for Marine Pathways Management and Incursion Response

This literature review synthesizes the current state of knowledge of marine non-indigenous species treatments, to help address biosecurity risks evident in two focal areas of relevance to marine biosecurity management in New Zealand. These two areas are:
1. the proactive treatment of shellfish aquaculture stock to facilitate biosecure stock transfers; and,
2. the reactive treatment of non-indigenous marine species to enable eradication at the landscape-scale.
The review summarises ~280 published papers in the global literature, outlining a number of chemical, physical and biological treatment options that have been tested to varying degrees. Each identified treatment type was assessed for several attributes in the review, including application regimes, efficacy, safety, the ability to monitor during deployment, biosecurity risks, and the regulatory environment that may influence acceptance and use in New Zealand. A number of these treatments are believed to be effective at small scales. Scaling-up one, or a combination of these identified treatments is likely the most efficient development route. Co-development and collaboration with the aquaculture, marine construction and commercial diving industries is likely to be critical to developing safe, effective and efficient implementation-ready treatment protocols..
