Big ocean（海洋） fish have almost been endangered since the start of business fishing in the 1950s. The scientists found that the number of large fish has dropped by 90 percent in the past fifty years. The study took ten years. The researchers（研究人员）collected records from fishing businesses and governments around the world. The magazine Nature published(发表) the findings.
The scientists say the common way called long-line fishing is especially harmful to large fish. This way includes many fishing lines that are connected to one boat. If these lines are joined together, they can reach one hundred kilometers. They hold thousands of sharp metal hooks(钩) to catch fish. Long-line fishing is especially common in the Japanese fishing industry. Records showed that Japanese boats used to catch about ten fish for every one hundred hooks. The study says long-line fishing boats now might catch one fish per hundred hooks.
The scientists say business fishing can destroy groups of fish much faster than in the past. It’s not the only worry that the number of large fish is becoming smaller and smaller. What’s worse, they are smaller in size than their ancestors（祖先）.

A giant panda from the Beijing Zoo has been saved by a transfusion（输血）of blood from two black bears. But it’s still under special care, according to the Beijing Zoo.
Yong Liang, two years old, is the first giant panda raised from birth in the zoo. Last month zoo keepers found the panda was suffering from serious anemia（贫血）, calling for urgent（紧急的）blood transfusion.
The best way, according to zoo’s experts（专家）, to save Yong Liang from anemia would have been to transfuse blood from another panda. But it was the breeding（繁殖） season for giant pandas, making such a transfusion very difficult.
But the experts found that there is a close consanguinity（血缘）between giant pandas and black bears, so they decided to try to take blood from black bears in the zoo and transfuse it to Yong Liang.
With the help of hospitals and Beijing Blood Donor Station（献血站）, they make an experiment which proved that the red blood cells（细胞）in the blood of black bears can be used.
On the afternoon of February15th the first red blood cell transfusion was given to the giant panda, from 600ml of black bear blood. Immediately the young panda started to get well again.
