CSIRO, Australia’s national science agency, in partnership with the Darwin Convention Centre and NT Business Events, is proud to invite you to the 22^nd International Symposium on Fish Nutrition and Feeding (ISFNF 2026). This biennial event will take place from 18 to 21 May 2026 in Australia’s tropical north, in Darwin, a city with the spectacular and unique natural landscapes of Kakadu, Litchfield, and Nitmiluk National Parks at its doorstep and where you can engage in the unique culture and art of Australia’s First Nations peoples.

In just over a decade since ISFNF 2014 in Cairns, Australia’s aquaculture production has doubled in value to AUD 2.2 billion. While Australia remains a relatively small producer globally, its aquaculture industry is highly diverse and innovative, spanning high-value species across the country — from temperate southern waters (salmonids, tuna, oysters, abalone) to the tropical north (tiger prawns, barramundi), with a growing interest in emerging candidates such as kingfish, grouper, Murray cod, freshwater perch species, mud crabs, sea cucumbers and tropical rock oysters and a new aquaculture species – Pompano ('Trachinotiu anak').

Aquaculture remains one of the fastest-growing food production sectors globally, bringing with it both significant challenges and exciting opportunities. To continue delivering meaningful innovation, aquaculture nutrition research must address the complex dietary needs of a diverse range of species, often raised in increasingly variable and suboptimal environments. Central to this is the development of sustainable aquafeeds and improved access to essential nutrients from circular and alternative ingredient sources. Advancing nutrition science not only supports sector growth, but also plays a vital role in improving animal welfare, enhancing the quality of aquatic food products, and securing the long-term sustainability of aquaculture.

We invite you to submit high-quality contributions aligned with the Symposium’s core themes, and to help drive progress in fish and shellfish nutrition science through research, knowledge sharing and global collaboration. ISFNF 2026 delegates will have the opportunity to engage with peers from around the world in a vibrant week of presentations, discussions, and organised visits to local research facilities and iconic Northern Territory attractions.

On behalf of the ISFNF 2026 Scientific Committee, we look forward to welcoming you to Darwin — Australia’s Top End and a gateway to Southeast Asia.
