Sustainable seafood initiatives, including certification and ecolabeling and awareness schemes, could be extended to more effectively cover inland, freshwater fisheries, according to researchers writing in the November issue of BioScience.
The world's growing dependence on fish protein and the imperiled state of many freshwater fisheries argues for such efforts, the authors conclude, although because freshwater fisheries tend to be smaller and are more concentrated in developing countries than marine and coastal fisheries, the efforts would have to be modified substantially to target the different consumers.
The article's authors, Steven Cooke of Carleton University and two colleagues, initially set out to assess the scientific literature on ecolabeling and awareness schemes as they related to freshwater species, but soon determined there were very few such studies.
Although freshwater species and those (such as salmon) that live in freshwater during part of their life cycle are included in lists intended for guide consumers on sustainable diet choices, they constitute a small minority, according to a survey of 10 certification and labeling schemes. This imbalance could lead to a public misperception that freshwater species are generally less at risk than marine species, Cooke and his colleagues argue.
Grassroots schemes, rather than multimedia marketing-oriented certification schemes, are the most promising approach to increasing awareness of the threats to freshwater species and what choices consumers can make to reduce these, the authors say, because many freshwater fisheries are artisanal.
BioScience, published monthly, is the journal of the American Institute of Biological Sciences (AIBS). BioScience publishes commentary and peer-reviewed articles covering a wide range of biological fields, with a focus on "Organisms from Molecules to the Environment." The journal has been published since 1964. AIBS is an umbrella organization for professional scientific societies and organizations that are involved with biology. It represents nearly 160 member societies and organizations.

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.
Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...
In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

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...
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...
