Modelling Asparagopsis nitrogen bioremediation efficiency in Australian coastal environments

Tormey Reimer, Katherine A. Cresswell, Kate M. Fraser, Camille A. White, Scott A. Hadley

Ecological Modelling, 2026

Coastal nitrogen enrichment poses a growing threat to marine ecosystems, and macroalgae cultivation has been identified as a promising bioremediation strategy in Australian coastal waters. Recent interest in cultivating Asparagopsis species as additives to livestock feeds presents an opportunity to leverage a commercial industry for ecosystem-based management goals, but the bioremediative potential of these species remain largely uncharacterised. An existing nitrogen-based macroalgae growth model is here adapted and parameterised for… Read more

High prevalence of vaterite in sagittal otoliths causes hearing impairment in farmed fish

Tormey Reimer, Tim Dempster, Fletcher Warren-Myers, Arne J. Jensen, Stephen E. Swearer

Scientific Reports, 2016

The rapid growth of aquaculture raises questions about the welfare status of mass-produced species. Sagittal otoliths are primary hearing structures in the inner ear of all teleost (bony) fishes and are normally composed of aragonite, though abnormal vaterite replacement is sometimes seen in the wild. We provide the first widespread evaluation of the prevalence of vaterite in otoliths, showing that farmed fish have levels of vaterite replacement over 10 times… Read more

Rapid growth causes abnormal vaterite formation in farmed fish otoliths

Tormey Reimer, Tim Dempster, Anna Wargelius, Per Gunnar Fjelldal, Tom Hansen, Kevin A. Glover, Monica F. Solberg, Stephen E. Swearer

Journal of Evolutionary Biology, 2017

Sagittal otoliths are essential components of the sensory organs that enable all teleost fish to hear and maintain balance, and are primarily composed of calcium carbonate. A deformity, where aragonite (the normal crystal form) is replaced with vaterite, was first noted over 50 years ago but its underlying cause is unresolved. We evaluated the prevalence of vateritic otoliths from two captive rearing studies which suggested that fast growth, due to environmental… Read more

Listen up: many farmed fish are hard of hearing – here’s why it matters

Tim Dempster, Stephen E. Swearer, Tormey Reimer

The Conversation, May 3, 2016

The swift rise of aquaculture as a major supplier of protein to the world is a remarkable story of rapid domestication of marine and freshwater animals.

Just a few years ago, the world produced more tonnage of farmed fish than it did beef. With billions of farmed fish now in production systems, the lives fish lead and their welfare status have… Read more
