Are Fish Stocks Overexploited?
The EU is currently adopting measures to recover hake and Norway lobster stocks to sustainable levels within a period of ten years. Many national and international initiatives are targeting a sustainable management of fish stocks all over the world. What is the state of fish production worldwide?
The United Nations Food and Agriculture Organization (FAO) has produced recently a scientific consensus report on the state of the world’s fishery resources. The report was drafted by high-level experts across the world. It analyses the use and trade of fishery products as well as the international management of fish stocks, and provides an overview of the global fishing and aquaculture production.
The report states that fish catches are indeed stagnating while aquaculture is expanding faster than any other animal-based food sector. The combined production has increased by 30% since 1995.
According to the report, the current state of fishery resources and their ecosystems requires prompt management decisions. It states that 25% of the world’s fisheries are overexploited or depleted, while an additional 50% are fully exploited, leaving little room for further increases in catches.
Furthermore, the report conveys growing concerns with regard to safeguarding the livelihoods of fishers as well as the sustainability of both commercial catches and the aquatic ecosystem from which they are extracted. It recommends assessing the interactions of fisheries with habitats, land-based activities, and climate change.
FAO report summarised by GreenFacts
GreenFacts has faithfully summarised the FAOs "State of the World Fisheries and Aquaculture" and published it in its reader-friendly Three-Level Structure of increasing detail at http://www.greenfacts.org/fisheries/.
Dr. Serge Garcia, Director of the Fishery Resources Division at FAOs Fisheries Department, reviewed the GreenFacts summaries and stated: "The GreenFacts Study on Fisheries reflects, in an accessible language, the essential findings of the FAO report. I am convinced that it will help raise awareness about the issues faced by the fisheries and aquaculture sector and wish to warmly congratulate GreenFacts for this very useful initiative."
Some of the questions answered by this GreenFacts Study include:
- What is the state of fishery resources?
- How are fishery products used?
- What contaminants are affecting fisheries?
- How are fisheries regulated?

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
Researchers from the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science, the Italian Space Agency (ASI), and the Instituto Geofisico--Escuela Politecnica Nacional (IGEPN) of Ecuador, showed an increasing volcanic danger on Cotopaxi in Ecuador using a powerful technique known as Interferometric Synthetic Aperture Radar (InSAR).
The Andes region in which Cotopaxi volcano is located is known to contain some of the world's most serious volcanic hazard. A mid- to large-size eruption has...
