Puducherry: Sixteen long-nosed dolphins were washed ashore dead at three places along the Puducherry coast on Monday. It has raised concern among environmentalists as it is the 20th instance in 16 months of protected marine mammals being washed ashore dead or alive.
Puducherry：16條長鼻海豚星期一被沖上岸，死在Puducherry沿岸三個地方。環保人士間已引起關注，因為它是16個月內第20宗例子被保護的海洋哺乳動物被沖上岸，毋論是死是活。
On an average, about 250 dolphins are washed shore dead or alive every year, said Dr R S Lal Mohan, retired principal scientist of the Central Marine Fisheries Research Institute (CMFRI).
平均來說，每年大約有250條死或活的海豚被沖到岸上，R S 拉爾磨憨博士說，中央海洋漁業研究所（CMFRI）的退休首席科學家。
A group of fishermen in Pudukuppam in the Union territory spotted five dead dolphins on the shore on Monday morning and alerted the forest and fisheries department officials. A few hours later, fishermen from neighbouring hamlets also informed them about 11 more dead dolphins found at two other places.
一羣Pudukuppam的漁民星期一早上在聯盟邊界內的岸邊發現 5條死海豚，並向林業和漁業部門的官員警報。幾個小時後，從鄰近村莊的漁民亦通知他們，約有 再多的11條死海豚發現在其它兩個地方。
A team of officials led by deputy conservator of forests Dr A Anil Kumar visited the hamlets and inspected the dead mammals. Veterinary doctors conducted postmortem examinations and buried 15 dolphins. One carcass was sent to Rajiv Gandhi College of Veterinary Sciences here for detailed analysis.
一隊由副保護森林員阿尼爾庫馬爾博士帶領的官員，訪問該些小村莊並視察死亡的哺乳類動物。獸醫們進行死後檢查和埋葬了15條海豚，一具屍體被送往這裡的拉吉夫甘地獸醫科學學院作詳細分析。
The dolphins measured between two-and-a-half feet and five feet. Ten were females of which two were found to be pregnant.
海豚量度在兩英尺半和五英尺之間，十條是女性，其中有兩條被發現懷孕。

Dolphins are marine mammals that inhabit relatively less deep regions of oceans. They are mainly carnivorous and feed on fish. They are also highly social and move in groups called pods. "All the dead dolphins washed ashore probably belonged a pod and none of them bore any external injuries," said Kumar. "Veterinary experts have conducted postmortem examinations."

According to him, it was a phenomenon of mass stranding' which is common among dolphins. "It's a phenomenon of mass stranding in which an entire group tends to drift to shallow parts of the ocean and fail to get back to their original trail," he said.

Experts in the veterinary college here will undertake further histopathological studies to ascertain the cause of death. The forest department will also seek the opinion of the scientists at CMFRI in Chennai. "Our analysis revealed that the mammals did not suffer from major diseases and only a detailed analysis will throw more light on the cause of death," Kumar said.

Lal Mohan, a member of the Cetacean Specialist Group, an international organisation, said mass stranding could be a reason for the deaths, but he also listed out other possible reasons. "Gill nets, high levels of pollution and radars sometimes spell doom for endangered marine species. Similarly, these mammals, particularly dolphins, follow the magnetic line of the earth and radar interference will affect their original trail, leading them to shallow waters," he said.
