The Yangtze River’s ecological environment is getting better - and to prove it 12 fish species have reappeared in the river’s mouth.
長江的生態環境正在轉好，12種魚在江口的重現證明了這一點。
They include the spotted maigre and the Chinese long-snout catfish.
其中包括黃姑魚和中華長吻鮠。
From 2012, more than 30 monitoring spots were set up in the Chinese Sturgeon Nature Conservation Area at Chongming Island near the estuary of Yangtze River, but the 12 species were not observed until the past year.
早在2012年起，國家就在長江口附近的崇明島中國鱘自然保護區安設了30多個觀測點，而這12個物種是去年才發現的。
Six species such as the spotted maigre have been frequently found in the conservation area in the past year, and the other six species, such as the long-snout catfish are also seen in the area, though not as frequently.
過去的一年裡保護區經常發現如黃姑魚等6種魚的身影，像肥頭魚等另外6種魚雖然沒有頻繁現身，但在保護區也出現過。
Yangtze River’s estuary, the passage for fish to travel between the river water and East China Sea, plays a key role in the fishery development along the huge river.
長江江口作為魚兒往返長江和東海的通道在長江漁業發展中起到了關鍵作用。
This is why the conservation area was set up at Chongming Island.
這就是該自然保護區設置在崇明島的原因。
In 2012, the conservation area’s management office set up an artificial fish shelter in the reservation area. The shelter comprises 2.5-meter-long bamboo poles with holes. The bamboos are set up in the water and the holes allow sand to flow in to stabilize the bamboos in the water.
在2012年，區域保護單位在保護區域建立起一個人工的魚類庇護所。這個庇護所由2.5米高的帶洞的竹竿組成。這些竹竿被插在水裡，留出的小洞是為了讓沙子可以流入來讓竹子穩固。
Moss grows on the poles, providing a source of food of fish, and loose sand at the bottom can attract animals that enjoy swimming in sand. The poles also serve as a shelter for young fish and shrimps when under attack from aggressive fish.
竹竿上的苔蘚成為了魚的食物，鬆軟的沙底成為喜歡在沙裡遊泳的動物的樂園。受到捕獵者攻擊時，竹子可以作為小魚和蝦的避難所。
Over the past five years, more than 330,000 bamboo poles have been set up in the river, and the shelter now covers an area of 13,000 square kilometers.
在過去五年裡，超過33萬個帶洞的竹竿被設置在河裡，庇護所覆蓋了13000平方千裡。
Officials said the shelter has made a significant contribution to improve the eco-diversity of the Yangtze River.
政府人員聲稱庇護處對提高揚子江的生態多樣化作出了重大貢獻。
