AEA Ignite - Gold Barramundi

Co Investigator

CRISPR gene editing is changing global food production by providing new ways to improve growth, quality, and sustainability. As these technologies progress worldwide, and as Australian regulations evolve to support their safe use, the country has an opportunity to build capability now and position itself as a leader in sustainable seafood production. This project focuses on barramundi, an iconic Australian fish and an important contributor to the national seafood industry. A key challenge for farmers is unwanted greying of fillets caused by melanin pigments, which reduces product value. Consumers prefer white fillets, which attract premium prices in both domestic and export markets. Building on proof-of-concept research at James Cook University (JCU), we will refine CRISPR editing protocols targeting two genes: tyrp (to reduce melanin) and mstn (to improve muscle growth and yield). In partnership with Mainstream Aquaculture, the world’s largest supplier of barramundi fingerlings, we will also develop a small-scale hatchery and nursery system to rear and assess edited fish under controlled, industry-relevant conditions. Within 12 months, the project will deliver a validated workflow alongside new operating procedures and performance benchmarks. These outcomes will support the production of whiter, higher-value fillets and help future-proof Australian aquaculture as precision breeding becomes central to global seafood production.
