| 中文摘要: |
| 美洲鲥在美国渔业史上曾起到重要作用。然而从十九世纪初期开始，建闸筑坝、水域的污染以及人们的过度捕捞造成美洲鲥种群数量急剧下降，目前美洲鲥从很多地区已经绝迹。然而，经过人们不断的努力，美洲鲥资源渐渐得到修复，每年在切萨皮克地区举行的鲥鱼节，让人们在庆祝这一自然文化财富的同时加深了对美洲鲥的更多了解。 |
| 英文摘要: |
| The American shad played an important part in the fishery history of the United States. Since the beginning and middle of the 1900s, however, dam-building, pollution, and overfishing have decimated shad populations. Today, many people have never even heard of the fish. Luckily, efforts to restore the shad are underway and annual shad festivals are helping people of the Chesapeake region learn about and celebrate this natural and cultural treasure. |
