[ti:In India, Sudden Sea Turtle Deaths Cause Concern] [al:As It Is] [ar:VOA] [dt:2025-01-31] [by:www.voase.cn] [00:00.00]Over 400 dead sea turtles have been found on India's east coast near the city of Chennai in the last two weeks. [00:12.38]Those numbers have not been seen in more than 20 years. [00:17.91]The species of turtle is known as olive ridley. [00:22.09]The animals travel thousands of kilometers for ideal places to lay their eggs along India's coast. [00:30.34]But that process, called nesting, has become more difficult because undisturbed beaches are becoming harder to find around the world. [00:41.31]And, mass deaths like these can be caused by fishing nets that can catch and harm the species. [00:50.88]Shravan Krishnan is a volunteer with Chennai-based Students Sea Turtles Conservation Network. [00:58.86]He told The Associated Press that in a usual year, there are between 100 to 200 adult turtle deaths on the city's coast. [01:10.52]"This year, we've already crossed 200 dead turtles in a little more than two weeks," he said. [01:19.02]Krishnan is also concerned about the low number of turtles nesting on shore. [01:25.15]He and other conservationists walk along the city's beaches at night to collect and move turtle nests. [01:34.97]They do so to prevent the eggs from being eaten by dogs or damaged by people walking along the coast. [01:42.69]"We have found only four nests so far, which is also really worrying," Krishnan said. [01:49.51]Environmentalists and forest department officials have been seeing at least ten dead turtles every day for the past few days, sometimes many more. [02:02.48]That is the highest number officials have seen since 2014. [02:07.69]Experts say the deaths are most likely caused by large fishing nets that are pulled along the ocean floor. [02:16.30]Manish Meena is in charge of the city's wildlife. [02:21.55]He said groups have been actively trying to inform people involved in fishing to release turtles that might get caught in nets. [02:31.06]They have also asked the coast guard to watch for illegal fishing activity. [02:38.26]Fishing boats using giant nets that catch everything on the ocean floor are barred by a local government order from operating within five nautical miles of the coastline during the turtle nesting season. [02:54.05]The law also requires the use of devices that can help turtles escape nets. [02:59.98]Shantanu Kalambi is an ocean animal specialist with the conservation organization ReefWatch. [03:08.53]He said that when the turtles get caught in nets, they are unable to come up to the surface for air. [03:16.15]And environmentalists say the crews of fishing boats do not always use the devices to help turtles escape, since they reduce how many fish they can catch. [03:28.41]Olive ridley turtles are considered an endangered species. [03:33.42]Just like most sea turtles, their eggs need two months to hatch. [03:38.90]This places them at higher risk because of coastal land activity, warmer temperatures and pollution from light. [03:48.13]Farther up India's east coast, over 500,000 turtles nest every year. [03:55.74]But only one in about 1,000 turtle babies that hatch survives to adulthood. [04:02.65]Experts say the turtles are important to the balance of the ocean ecosystem. [04:09.45]"As a species, they are millions of years old and they play an essential role in the food chain," Kalambi said. [04:19.13]I'm Jill Robbins.
