Curious Science: 3 big questions

City of Sydney Library is teaming up with Inspiring Australia to delve into some cutting-edge research. Over three seasons, we’ll be focusing on three big-impact topics: food, obesity and STEM (science, technology, engineering and mathematics) skills. In this series, Feeding the World, we’ll be focusing on food and exploring the role science plays in contributing innovative solutions to global issues.

Keeping fish sustainable

Fish is a cheap source of quality food worldwide.

High in protein, oils and micronutrients, our love of seafood just keeps growing but the ocean’s supply stopped flowing in the 1990s. To keep up with demand, more than 40% of fish now comes from aquaculture and this is not without consequence. The rise in ‘seafood farming’ goes hand-in-hand with coastline reshaping while ‘sea ranching’ is seeing synthetic habitats turn natural fisheries into controlled ‘farmed’ systems.

The impact of farm management on disease is very apparent in Indonesia where high value species of grouper are produced in onshore hatcheries and grown in sea cages for live fish markets. On-farm disease surveys are used to understand the multifactorial causes of mass mortality that threaten the reliability of these farming systems.

Dr James Smith

A Research Associate in the Fisheries and Marine Environmental Research group at the University of NSW. Dr Smith’s expertise covers many topics, from artificial reefs and fish stocking, to food webs and fish tracking. He explores the past and future of seafood production and asks whether we will always be able to find or farm seafood.
