Gharial found dead in Chambal river in Etawah dist

TNN Aug 9, 2012, 08.02AM IST
KANPUR: A gharial was found dead on Wednsday in Chambal river near Udi bridge in Etawah district.
The death of gharial came barely three days after the recovery of a dead Gangetic dolphin in the Sahson area in the upstream of Chambal river in the district on August 5.
 
The dead gharial, which was in a highly decomposed state, was about 3.5 ft in size.
The dead gharial was found to be wearing a yellow colour tag with a serial number 41 inscribed on it, which according to the environmentalists only suggests that the gharial was released by some gharial conservation agency in the river in order to track the movement of critically endangered species.The tracking is expected to help assess the reptile's survival rate and the status of its preferred habitat in rivers across the region.
In 2007, gharial ( Gavialis gangeticus) was listed as "Critically Endangered" in the IUCN Red List of Threatened Species.
The recovery of a dead gharial with a number tag, however, has left the UP forest department officials perturbed. "As such kind of tagging has not been done by us, we therefore contacted officials of Deori Gharial breeding centre of MP (Madhya Pradesh) and apprised them about the dead gharial, but they also feigned ignorance about any such tagging activity being carried by them in recent time," said Mahaveer Prasad, range officer, National Chambal sanctuary.
Gharials are only released in their habitat after they attains the age of three years and grew upto 120 cm in size.
Prasad further said that as the carcass was in highly decomposed state it was difficult to ascertain the exact cause of death at this point of time. "We would try to find out the immediate cause by conducting its post-mortem," he added. Sources, however, informed that the body of gharial was found to be entangled in a fishing net, which suggested that the fishermen might have killed the reptile when it apparently got entangled in fishing net.
Currently, besides Chambal, gharials are found only in the Ganga, the Brahmaputra and the Mahanadi river systems in India and Nepal.
From November, 2007 till March, 2008, more than 112 gharials have died in the Chambal river from an unknown disease with gout-like symptoms. This recent death toll is expected to have decreased the number of breeding pairs. In 2007-2008, most of the gharials were found dead near the Sahson, the same spot where a female gangetic dolphin and a gharial have been found dead in past couple of days.
The World Wide Fund for Nature-India estimates that more than 100 gharials have died in the sanctuary since December 2007. Most of the dead gharials were spotted at the confluence of the rivers Chambal and Yamuna. The river Chambal is the largest of only three remaining breeding populations of gharial left in the world.
According to Rajiv Chauhan, secretary society for conservation of nature, who was actively involved with the conservation of gharial in the region said, "If measures of protection are not intensively taken then gharials would be wiped out from the region."

Chambal dry, gharials on high

Delayed and scanty rains may be leading to a drought-like scenario in the country, but it is proving more than beneficial for the conservation of gharials in its stronghold of the National Chambal Sanctuary. A record number of eggs of this critically endangered species have hatched this year in the sanctuary, reversing their rate of extinction. The species is under Schedule-I of the Wildlife Protection Act 1972.
An unprecedented number of 2,340 eggs have hatched in about 68 nests this year which is the highest ever since the commencement of gharial conservation efforts in 1975. The Chambal sanctuary spreads across the States of MP, Rajasthan and UP and accounts for the majority of gharial population in the country.
According to Sujoy Banerjee, Deputy Conservator National Chambal Wildlife Division, Agra, mortality is usually higher in the gharial hatchlings, as they get washed away in floods, which is a common phenomenon in the Chambal River. But scanty and delayed rains this year, seem to be auguring well for their conservation. While there has been an exceptionally high hatching of gharials, the relatively dry spell has provided enough time for the hatchlings to grow up and survive in the Chambal stream.
“This was coupled with round the clock vigil of the forest staff on the banks of Chambal River during the nesting season which stretch from March-May. After the female gharials lay eggs and leave, the nests are identified. They are then enclosed with square wire mesh to ward off dogs, jackals and other animals, which dig and destroy the eggs”, he added.
Meanwhile, the species faced a major threat in 2007 when about 150 adult gharials died because of reasons still not known. “But the crisis now appears to have been overcome. The number of nests protected this year has gone up to 68 from 15 in 2007-08”, said Bannerjee.
 Record hatchlings
In 2007-08, 359 offsprings had hatched in about 15 nests. The count increased to 1,000 in double the number of nests during the following year. In 2009-10, 1,131 juveniles emerged out of 32 nests. In 2010-11, 1,009 offsprings had hatched from the same number of nests. Though the numbers may appear impressive, the average survival rate of the juveniles is low. Studies estimate the total number of breeding adult gharials in the country to be less than 200.
