Coral reef fish eggs
Fishy noises could be the answer for improved reef fisheries management according to an international team of researchers.
Some juvenile coral reef fish are attracted by sounds they would have heard while they were in the egg. By using these sounds, the fish can be led to artificial reefs where they will start new colonies. It may be possible in the future to lead young fish into overfished areas, and super-stock Marine Protected Areas.
Marine biologist Stephen Simpson of the University of York fronts the international team. He explains, “Many coral reef fish are spawned on the reef, and while the eggs develop, their noisy parents look after them. Once they hatch, the ant-sized fish escape out to sea for a month to escape the many predators on the reef. There they develop into juveniles. They wait for the new moon and then, under the cloak of darkness, they cross the ‘wall of mouths’ to settle on a reef. This research has also solved a mystery - how they choose a reef has baffled us for many years.”

Researchers at Chalmers University of Technology and the University of Gothenburg, Sweden, have proposed a way to create a completely new source of radiation. Ultra-intense light pulses consist of the motion of a single wave and can be described as a tsunami of light. The strong wave can be used to study interactions between matter and light in a unique way. Their research is now published in the scientific journal Physical Review Letters.
"This source of radiation lets us look at reality through a new angle - it is like twisting a mirror and discovering something completely different," says...
