  • Shifts in Mediterranean fish farming increase pressure on wild fish stocks

    Fish farming in the Mediterranean has increasingly shifted from producing fish such as grey mullet, which are herbivores near the bottom of the food chain, to species such as sea bass, which are predators. This ‘farming up’ the food chain requires wild fish to be caught to provide feed. A return to farming fish lower in the food chain would use marine resources more efficiently, a new ...

  • Fishing for sustainable practices to conserve fisheries

    Global fish production has reached an all-time high, according to research done by Nourishing the Planet (www.NourishingthePlanet.org) for the Worldwatch Institute’s Vital Signs Online publication. Aquaculture, or fish farming—once a minor contributor to total fish harvest—increased 50-fold between the 1950s and 2008 and now contributes nearly ...

  • Ecosystem-based farming comes of age

    A new FAO book out today takes a close look at how the world's major cereals maize, rice and wheat - which together account for an estimated 42.5 percent of human calories and 37 percent of our protein - can be grown in ways that respect and even leverage natural ecosystems. Drawing on case studies from around the planet, the ...

  • Sting operation - jellyfish `blooms` may endanger fish stocks

    Surges in jellyfish populations may be one reason for a drop in fish stocks observed in the Mediterranean and Black Sea, according to a new report published by FAO. Overfishing, which removes top predators from the sea, is one of the factors behind jellyfish "blooms", or suddenly increased numbers. A "vicious circle" can then follow in which large numbers of medusae feed on fish larvae and ...

  • Things to know about marine aquaculture

    Some 90 percent of seafood consumed by Americans is imported, yet the Obama administration's push to expand U.S. marine aquaculture into federal waters has failed to see one offshore farm in operation, nearly two years after the first permit was issued. The National Oceanic and Atmospheric Administration is pushing for marine aquaculture production in the U.S. to jump by 50 percent by 2020. The ...

  • Overfishing Threatens Critical Link in the Food Chain

    The fish near the bottom of the aquatic food chain are often overlooked, but they are vital to healthy oceans and estuaries. Collectively known as forage fish, these species—including sardines, anchovies, herrings, and shrimp-like crustaceans called krill—feed on plankton and become food themselves for larger fish, seabirds, and marine mammals. Historically, people have eaten ...

  • Jellyfish infestations caused by human activities

    A huge rise in jellyfish populations around the world appears to be caused by human activities, according to recent research. Early action is essential to prevent marine ecosystems from changing to unhealthy states that favour destructive jellyfish blooms. Although large numbers of jellyfish can occur in healthy marine ecosystems, destructive jellyfish blooms are being observed more frequently in ...

  • Salmon Migrate by Truck during California Drought

     In drought-stricken California, young Chinook salmon are hitting the road, not the river, to get to the Pacific Ocean. Millions of six-month-old smolts are hitching rides in tanker trucks because California's historic drought has depleted rivers and streams, making the annual migration to the ocean too dangerous for juvenile salmon. "The drought conditions have caused lower flows in the ...

  • IRRI calls for stricter controls on use of pesticides

    Governments across Asia need to improve their regulation of way that pesticides are marketed, and should ban certain pesticides from use in rice production completely, according to the International Rice Research Institute (IRRI), which is based in Manila, the Philippines. IRRI released an action plan listing potential strategies for scaling back pesticide use and adopting ecological ...

  • Ministries Need to Collaborate to Ensure Continued Productivity of Farmland and Forests in ECA

    As economies in the ECA region grow, farm and forest productivity will need to keep pace with rising consumer and industrial demand for food and wood.  But doing so by pushing natural resources beyond their limits can be disastrous. Governments in the region have taken steps to address this issue, but they – ministries of environment in partnership with others such as agriculture, forestry ...

  • Ethanol`s rise can mean loss of hunting lands

    Pheasants once drew hundreds of weekend hunters to Fairbury, Neb., each fall, filling the 45 rooms at Randy Brown's Capri Motel with sportsmen eager to bag their limits. But times have changed. The native grasslands and milo crops that used to dot surrounding Jefferson County have been overtaken by corn and soy crops. Neither provides the shelter that wildlife once enjoyed. This year's opener ...
