A fishy tale - science aids conservation

19.02.2003


University of Leicester biologist Dr Paul Hart has been carrying out a study to reveal the “Biological and Socio-economic Implications of a Limited Access Fishery Management System”, detailing the arguments for and against keeping different methods of fishing apart.



His aim is to discover a fishery management system which will encourage co-operation between stake-holders using the coastal zone. Dr Hart is working on this with two leading scientists from the University of Wales, Bangor (School of Ocean Sciences and School of Agricultural and Forest Sciences), South Devon local trawler organisations and the South Devon & Channel Shell-Fishermen’s Association (SD&CS).

PhD student Robert Blyth (funded by the Isle of Man Government), who is working with Dr Hart on this conservation project, is operating hands-on to collect data aboard South Devon fishing boats. So far, Robert has spent 38 days at sea on 14 different fishing vessels, earning him the respect of local fishermen.


A pattern of data has already been built up which may reveal important seasonal changes in fishing habits, and it is hoped that it may provide a better understanding of the ‘essential fish habitat’, the conditions on the sea bed required for stocks to remain healthy. This not only benefits shellfish, but acts as a conservation measure for species such as scallops, not targeted inside the potting only boxes. The study is also examining how fishers interact with each other on the fishing grounds and how these interactions are influenced by the fishers’ social background.

Local fishermen joined scientists during the late summer aboard the marine science research vessel Prince Madog, to gain a better understanding of the seabed inside and outside the potting only areas. Prince Madog operates by towing a remote video camera, a bottom dredge, and records electronic side scan sonar images.

“This is a proper scientific survey and it will allow us to evaluate the damage to the seabed from potting, trawling and other modes of fishing”, explained Robert Blyth. “There are also theories of crab migration we would like to study further, and accurate catch records from boats working in the potting boxes would give us a tremendous insight into the mystery of crab movements”.

Altogether, the survey hopes to untangle the complex way in which fishers’ behaviour, resource ecology and economics interact in the fishing industry, with the ultimate aim of generating sustainable fisheries management regimes. These are urgently needed if fishing communities are to continue to provide a vital source of employment in rural areas.

Im Focus: New double-contrast technique picks up small tumors on MRI

Early detection of tumors is extremely important in treating cancer. A new technique developed by researchers at the University of California, Davis offers a significant advance in using magnetic resonance imaging to pick out even very small tumors from normal tissue. The work is published May 25 in the journal Nature Nanotechnology.

Im Focus: I-call - When microimplants communicate with each other / Innovation driver digitization - "Smart Health“

Microelectronics as a key technology enables numerous innovations in the field of intelligent medical technology. The Fraunhofer Institute for Biomedical Engineering IBMT coordinates the BMBF cooperative project "I-call" realizing the first electronic system for ultrasound-based, safe and interference-resistant data transmission between implants in the human body.

When microelectronic systems are used for medical applications, they have to meet high requirements in terms of biocompatibility, reliability, energy...

Im Focus: When predictions of theoretical chemists become reality

Thomas Heine, Professor of Theoretical Chemistry at TU Dresden, together with his team, first predicted a topological 2D polymer in 2019. Only one year later, an international team led by Italian researchers was able to synthesize these materials and experimentally prove their topological properties. For the renowned journal Nature Materials, this was the occasion to invite Thomas Heine to a News and Views article, which was published this week. Under the title "Making 2D Topological Polymers a reality" Prof. Heine describes how his theory became a reality.

Ultrathin materials are extremely interesting as building blocks for next generation nano electronic devices, as it is much easier to make circuits and other...

Im Focus: Rolling into the deep

Scientists took a leukocyte as the blueprint and developed a microrobot that has the size, shape and moving capabilities of a white blood cell. Simulating a blood vessel in a laboratory setting, they succeeded in magnetically navigating the ball-shaped microroller through this dynamic and dense environment. The drug-delivery vehicle withstood the simulated blood flow, pushing the developments in targeted drug delivery a step further: inside the body, there is no better access route to all tissues and organs than the circulatory system. A robot that could actually travel through this finely woven web would revolutionize the minimally-invasive treatment of illnesses.

A team of scientists from the Max Planck Institute for Intelligent Systems (MPI-IS) in Stuttgart invented a tiny microrobot that resembles a white blood cell...

Im Focus: NASA's Curiosity rover finds clues to chilly ancient Mars buried in rocks

By studying the chemical elements on Mars today -- including carbon and oxygen -- scientists can work backwards to piece together the history of a planet that once had the conditions necessary to support life.

Weaving this story, element by element, from roughly 140 million miles (225 million kilometers) away is a painstaking process. But scientists aren't the type...
