There are over 100 exotic marine species reported from Australian waters. Almost all these species are unintentional introductions associated with mariculture and shipping activities. The importance of the different introduction methods has changed over various phases of Australian maritime history; hull fouling and ballast water discharge by shipping remain important vectors for the entry of exotic species into Australian ports.

A prerequisite for any attempt to control the spread by shipping of introduced marine pest species in Australian waters is a knowledge of the current distribution and abundance of exotic species in Australian ports. This information base is lacking for nearly all Australian ports. Recognition of the need for baseline studies led the CSIRO Centre for Research on Introduced Marine Species (CRIMP) and Australian Association of Ports and Marine Authorities (AAPMA) to initiate an introduced species port survey program. As port surveys designed to identify all exotic species will inevitably be subject to scientific, logistic and cost constraints, CRIMP and AAPMA have adopted a targeted approach which concentrates on a known group of species and provides a cost effective approach to the collection of baseline data for all ports.

As a number of agencies and research organisations are likely to participate in the national port survey exercise, the development of a uniform approach to surveys and a set of standard survey methods is a key requirement for the program. This technical report outlines the approach to survey design and the sampling protocols adopted by CRIMP for introduced species port surveys under the CRIMP/AAPMA agreement, and provides recommended archiving (data and specimens) and reporting requirements for an effective national survey program.
