About the report

This document is the final report of the second of two one-year projects designed to collect quantitative information on small vessel biofouling. Both projects support the development and implementation of the new National System for the Prevention and Management of Marine Pests in Australia, with particular emphasis on Asterias amurensis (Stage I) and Undaria pinnatifida (Stage II).

The four primary aims of Stage II of this project were to:

1. Develop a new genetic probe for Undaria pinnatifida;
2. Sample the internal and external spaces and surfaces of small vessels to determine their translocation potential using the genetic probes for Asterias amurensis and Undaria pinnatifida;
3. Develop a Bayesian journey survival model to estimate the probability of target species survival on small vessels; and
4. develop quantitative risk factors for fouling biomass based on vessel activity, paint type and management practices.
