中华海豚（Sousa chinensis Osbeck，1765）是生活在中国沃茨的濒危物种.尽管受到保护关注，但该物种的分布和丰度尚未得到全面评估。从1994年到2008年，我们进行了超过14 000公里的样线调查，并管理了700多份问卷，以收集基本信息的地理范围和可能丰富的印度太平洋驼背豚沿着中国南部和东部沿海。通过我们的研究，我们能够建立一个报告网络的搁浅和偶然捕获的这个物种。定量数据显示，厦门周边地区现存76只，合浦自然保护区39只，大丰江口114只。当地渔民和政府官员的定性数据表明，海豚可能全年存在于宁德和汕头的沃茨。我们发现，在这个重要的区域，中国苏萨野生种群明显受到人为干扰和栖息地恶化，包括水下爆破，船舶碰撞，捕鱼，水产养殖和水污染的影响。虽然一些保护区已经建立，这一物种受到中国法律的保护，但这种动物几乎没有受到保护。
The Indo- Pacific humpback dolphin (Sousa chinensis Osbeck, 1765) is a threatened species inhabiting the waters of China. Despite being of conservation concern, the distribution and abundance of this species has not been comprehensively evaluated. From 1994 to 2008 we performed over 14 000 km of line-transect surveys and administered over 700 questionnaires to collect basic information on the geographic range and likely abundance of Indo Pacific humpback dolphins along the southern and eastern coasts of China. Through our study we were able to establish a reporting network of stranding and incidental catches for this species. Our quantitative data suggests that only 76 animals remain around Xiamen, 39 in the Hepu Nature Reserve and 114 in the estuary of the Dafengjiang River. Qualitative data from local fishing people and government officials suggests that dolphins may exist year-round in waters off Ningde and Shantou. We found that wild populations of Sousa chinensis in this important region are clearly being affected by human disturbance and habitat deterioration, including underwater blasting, vessel collision, fishing, aquaculture and water pollution. Although some protected areas have been established and this species is protected under Chinese law, there remains virtually no protection for this animal.
