The Institute for Ocean Conservation Science applauds IUCN's reclassifcation of beluga sturgeon

19.03.2010
The world's largest global environmental network announces that more sturgeon species are critically endangered than any other comprehensively assessed group of species

The International Union for the Conservation of Nature (IUCN) today formally announced the reclassification of beluga sturgeon in the Caspian Sea as "critically endangered" on its Red List, providing strong evidence that fishing and international trade should be halted and a stock-rebuilding plan should be initiated immediately. Beluga sturgeon populations have been decimated in part due to unrelenting exploitation for black caviar – the sturgeon's unfertilized eggs – considered the finest in the world.

"For those of us who have been involved in studying the rapid decline of this species over the past several decades, this reclassification of beluga sturgeon is of great significance and relief," said Dr. Ellen Pikitch, Professor and Executive Director of the Institute for Ocean Conservation Science at Stony Brook University. "However, of even greater significance is the IUCN reclassification of many sturgeons, which shows them to be among the most imperiled animals on earth. A higher percentage of sturgeon species were designated as critically endangered than any other group of species assessed, including other fish, mammals, reptiles, amphibians and plants."

Dr. Pikitch has led scientific efforts to highlight the seriously depleted status of the beluga sturgeon and to secure protection for the species for more than a decade. Dr. Pikitch was one of the petitioners of the U.S. Fish and Wildlife Service (USFWS) seeking listing of the species under the U.S. Endangered Species Act (ESA). Beluga sturgeon were listed under the U.S. ESA in 2004, and imports of its products into the United States have been banned since 2005.

The Institute for Ocean Conservation Science at Stony Brook University contributed significant new scientific information on several species of sturgeon to the newly released IUCN Red List sturgeon assessment. Dr. Ellen Pikitch, Executive Director, and Dr. Phaedra Doukakis, Senior Research Scientist with the Institute for Ocean Conservation Science are members of IUCN's Sturgeon Specialist Group (SSG).

They recently co-authored, along with other U.S. and Kazakhstani scientists, the results of a study of Caspian Sea beluga sturgeon of the Ural River. The results, which were published online this month in the journal Conservation Biology, suggest that conservation strategies for beluga sturgeon should focus on reducing the overfishing of adults rather than heavily relying upon hatchery supplementation and also demonstrate that current harvest rates in the fishery are four to five times higher than those that would sustain population abundance.

"This study only adds more credence to the reclassification of beluga sturgeon as 'critically endangered,' and underscores the need for swift, international protection to help them stave off extinction," said Dr. Pikitch. "And, the new IUCN assessment demonstrates that almost all of the 27 sturgeon species need enhanced protection since conservation measures to date have not been sufficient to ensure the recovery and long-term persistence of these valuable and ancient fish."

Drs. Pikitch and Doukakis presented their latest findings, as well as an overview of status and trends of global sturgeon fisheries, at a meeting during the 15th meeting of the Conference of Parties to CITES in Doha, Qatar. Also presenting were Dr. Kent E. Carpenter, IUCN Global Marine Species Assessment Director, on the reclassification of the sturgeon species, and Dr. Volker Homes, Species Conservation Section Director, WWF Germany and TRAFFIC, on caviar trade and labeling.

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

Im Focus: Fraunhofer ISE Develops Highly Compact, High Frequency DC/DC Converter for Aviation

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
