"This happened in Hawaii," he said, "and it appears to have had little impact on the socioeconomic well-being of fishers who remained involved in the fishery since before the MPAs were in place, which is somewhat counterintuitive and makes our study interesting."
Without a separate economic analysis, said Stevenson, it's hard to say how the changing fish stocks might have affected fishing incomes. He and his co-authors—WSU Professor Brian Tissot and Bill Walsh of Hawaii's Division of Aquatic Resources—conjecture the fishers had higher yields, in part because they were steered toward underexploited or more biologically productive areas.
Fishers also benefited from rising prices for yellow tang, the most abundant and popular fish in Hawaii's aquarium trade, and price wars among island buyers working to satisfy the growing demand from coral aquarium tank owners.

World first experiments on sensor that may revolutionise everything from medical devices to unmanned vehicles
The new sensor - capable of detecting vibrations of living cells - may revolutionise everything from medical devices to unmanned vehicles.
Dead and alive at the same time? Researchers at the Max Planck Institute of Quantum Optics have implemented Erwin Schrödinger’s paradoxical gedanken experiment employing an entangled atom-light state.
In 1935 Erwin Schrödinger formulated a thought experiment designed to capture the paradoxical nature of quantum physics. The crucial element of this gedanken...
Cellulose obtained from wood has amazing material properties. Empa researchers are now equipping the biodegradable material with additional functionalities to produce implants for cartilage diseases using 3D printing.
It all starts with an ear. Empa researcher Michael Hausmann removes the object shaped like a human ear from the 3D printer and explains:
The phenomenon of so-called superlubricity is known, but so far the explanation at the atomic level has been missing: for example, how does extremely low friction occur in bearings? Researchers from the Fraunhofer Institutes IWM and IWS jointly deciphered a universal mechanism of superlubricity for certain diamond-like carbon layers in combination with organic lubricants. Based on this knowledge, it is now possible to formulate design rules for supra lubricating layer-lubricant combinations. The results are presented in an article in Nature Communications, volume 10.
One of the most important prerequisites for sustainable and environmentally friendly mobility is minimizing friction. Research and industry have been dedicated...
