Yellowtail kingfish (Seriola lalandi) and Mahi mahi (Coryphaena hippurus) are increasingly important to New South Wales fishers with escalating consumer demand. Incidents of muscle parasite infections that cause muscle softening in both species have been reported with increasing frequency in recent years. These parasites are adversely impacting consumer confidence in the product.

This project will determine the efficacy of ultrasound imaging to detect muscle parasites and the threshold of detection of each parasite in both fish species. This project will also identify the species and the rate of incidence of the identified muscle parasites in both Yellowtail kingfish and Mahi mahi.
