Industry stakeholders have a need to prevent fish infected with these parasites, being further traded through the value chain. However, identifying an appropriate level of technology will be the challenge to stakeholders. Such technology will need to be cost effective, non-destructive, rapid and relatively simple to use. Stakeholders also need to identify the parasites concerned for both species, and identify technology capable of screening out such infected fish is required in the processing environment. The work proposed here will identify the parasite concerned for both species, identify appropriate technology applicable is a regional processing environment, and trial such technology at the place of processing in NSW.


1. Determine the efficacy of ultra sound imaging to detect muscle parasites in Yellowtail kingfish and Mahi mahi (proof of concept).

2. Conduct field trials of the US technology on site in a commercial fish processing facility to determine suitability to that environment and determine the threshold of detection of each parasite

3. Identify species of muscle parasite affecting Yellowtail Kingfish and Mahi Mahi from northern NSW waters.

4. Establish rate of incidence of identified muscle parasites in Yellowtail Kingfish and Mahi Mahi.
