Getting the Most out of Aquaculture: Pearls of Wisdom from Farmed Oysters

07.10.2014

Research to be presented at the APS comparative physiology meeting in San Diego

As global populations rise, so does the demand for seafood. In developed nations, the health benefits of a diet high in fish and seafood are regularly touted. In developing nations, fish and seafood often comprise a large portion of the diet.

Aquaculture—farming of fishes, mollusks, crustaceans and plants in an aquatic environment—is a booming business (approximately $119 billion in the US in 2010) and the fastest growing form of global food production. It holds promise for both satisfying our taste for seafood and combatting global food insecurity.

Sarah Andrewartha et al. at CSIRO Integrated Sustainable Aquaculture Production and the University of Tasmania are studying oysters for clues into how environmental conditions and stressors affect their ability to grow and thrive.

“We’re remotely monitoring changes in oyster heart-rate and feeding behavior with small biosensors. The oysters wearing biosensors act as sentinels and provide real-time information on how oysters are responding to changing environmental conditions or farm stressors,” Dr. Andrewartha said. “They provide us with laboratory data that relate heart rate to overall energy use on-farm.”

Oysters are a popular target species for aquaculture and are farmed internationally. Determining how they respond to temperature, water depth and light levels could help improve understanding of how they and other animals raised through aquaculture will react to changing conditions and adapt to their environment.

Their research adds to the growing body of work focused on understanding the conditions that enable target aquaculture species to flourish.

Andrewartha will present the talk “Real-time physiology: Can it assist aquaculture productivity” at the American Physiological Society (APS) intersociety meeting “Comparative Approaches to Grand Challenges in Physiology” (October 5–8, 2014, in San Diego). “During my talk, I’ll discuss the need for biosensors in aquaculture, collection of ground-truth data and two applications where biosensors are currently being used on-farm,” she added.

APS jointly hosts this intersociety meeting with the Society for Experimental Biology, Society for Integrative and Comparative Biology, Australian and New Zealand Society for Comparative Physiology and Biochemistry, Canadian Society of Zoologists, Crustacean Society and International Society for Neuroethology.

Physiology is the study of how molecules, cells, tissues and organs function in health and disease. Established in 1887, the American Physiological Society (APS) was the first U.S. society in the biomedical sciences field. The Society represents more than 11,000 members and publishes 14 peer-reviewed journals with a worldwide readership.

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
