Traditional fisheries may no longer be the world's most important provider of fish.  1 . The Food and
Agriculture Organization says aquaculture is growing by a rate of 6.6 percent a year.
     Aquaculture now produces forty-six percent of the world's supply of fish.  2 . The report also said
aquaculture earned more money in 2008 than traditional fisheries.
    In aquaculture, fish are raised in tanks or small bodies of water called ponds. They also are raised in
cages or nets in oceans, lakes and rivers.
     The report says increased aquaculture has helped people around the world eat record amounts of
fish.  3. But the FAO says the current yearly wild-fish harvest of 90 million tons shows no improvement.
Decreasing numbers of fish and stronger catch limits have reduced the possibilities for catching wild fish.
     The FAO report says about thirty-two percent of world supplies are overfished, depleted(大量削减)
or recovering. It said these supplies of fish need to be urgently rebuilt.
      4. They say the nets and cages permit fish diseases and pests to spread. Some aquaculture critics
doubt that aquaculture can keep growing at the current rate. But Wally Stevens of the trade group
Global Aquaculture Alliance says the industry must continue developing to feed growing populations.
     Mr. Stevens says a one hundred percent increase in fish farming over ten years is necessary to keep
providing for people at the current level. He notes that aquaculture creates jobs and wealth, especially
for people in coastal areas of China. The FAO reports that China remains the world's largest
fish-producing nation.  5.
A. Hungary is rich in waterways, but traditionally most Hungarians eat fish only at Christmastime.
B. A new United Nations report shows that fish farming or aquaculture may soon lead fish production.
C. Last week a study of one hundred ninety-nine countries and territories confirmed what many people
may have already noticed.
D. The FAO says each person ate an average of almost 17 kilograms of fish last year.
E. China produces more than sixty percent of the world's farmed fish.
F. That represents a forty-three percent increase from 2006.
G. Some scientists have criticized aquaculture.
