Marine Ecologists to Help Rebuild Decreasing Fish Stocks

16.02.2006


Marine ecologists are working with fisheries across Europe to further understanding of natural and human influences on decreasing fish populations.



Work has begun in the North East Atlantic, Baltic, North East Atlantic and Iberian Sea area to increase the level of scientific information available to fisheries. This will allow the fishing industry to produce new strategies for providing fish stocks for human consumption. Professor Chris Frid from the University’s School of Biological Sciences has received funding of one million Euros from the EU to carry out the three-year project, in collaboration with research institutes in Portugal, Iceland, the Netherlands, Germany, Poland, Italy, Sweden and Denmark.

Professor Frid said: “In recent years fish stocks have reached unprecedented low levels. While the fishing industry has been keen to identify pollution and global warming as the causes, it is also clear that fishing has removed large numbers of fish and altered the way the ecosystem works. Everybody would like to see the rebuilding of fish stocks and this can only be achieved if we understand all of the influences, human and natural, on fish dynamics.”


The project, Incorporating Extrinsic Drivers into Fisheries Management’, (IN EX FISH), aims to increase the responsiveness of fisheries management to a range of human and non-human effects on the marine environment, such as variations in water temperature, fishing and pollution.

Professor Frid added: “Fish communities can be altered in a number of ways, for example they can decrease if particular sized individuals of a species are targeted, as this affects predator and prey dynamics. Fishing, however, is not the sole perpetrator of changes to marine life - pollution is another example.

“No one factor operates in isolation and components of the ecosystem respond differently to each individual factor. We aim to identify these factors, both human and non-human, and use them to produce a system for fishing industries in which we can help bolster marine life, rather than watch it continue to deteriorate.”

The team will draw together research from around the world, such as the work of the International Council for the Exploration of the Sea, to produce new management strategies for marine industries throughout Europe.

Im Focus: Towards data storage at the single molecule level

The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.

Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...

Im Focus: A space-time sensor for light-matter interactions

Physicists in the Laboratory for Attosecond Physics (run jointly by LMU Munich and the Max Planck Institute for Quantum Optics) have developed an attosecond electron microscope that allows them to visualize the dispersion of light in time and space, and observe the motions of electrons in atoms.

The most basic of all physical interactions in nature is that between light and matter. This interaction takes place in attosecond times (i.e. billionths of a...

Im Focus: A transistor of graphene nanoribbons

Transistors based on carbon nanostructures: what sounds like a futuristic dream could be reality in just a few years' time. An international research team working with Empa has now succeeded in producing nanotransistors from graphene ribbons that are only a few atoms wide, as reported in the current issue of the trade journal "Nature Communications."

Graphene ribbons that are only a few atoms wide, so-called graphene nanoribbons, have special electrical properties that make them promising candidates for the...
