February 17, 2013 - INDIA - Nearly 100 carcasses of the endangered Olive Ridley turtles were
washed ashore under mysterious circumstances, baffling scientists and
locals, at the coast of Appikonda beach in Andhra Pradesh state.
According to reports,
this is one of the highest death tolls of Olive Ridleys in Vizag district after a span of four years.
The
Olive Ridley turtles, which are listed as an endangered species, land
up in thousands on Indian shores between the months of November and
March.
100 Turtles Wash Ashore Dead In Andhra Pradesh, India.
The head of the environmental science department,
E.U.Bhaskar Reddy, said the cause of the deaths of the turtles is yet to
be ascertained.
"Some of the species in the population might be
growing older, some may have become sick and some may after death,
natural death the worse thing will be throwing them out and these
carcasses will be coming to the shore and we have to verify whether
these turtles they are coming to the shore in a complete dead state or
sick state, then only we can comment," said Reddy.
In February
2008, nearly 700 Olive Ridleys were declared dead on the beaches of
Appikonda, Tantadi, Mutyallammapalem and Tikkavanipalem.
Not only turtles, but even territorial fish are becoming victims of the unchecked pollution.
A
biopsy was conducted in 2008 on the dead turtles and the reports
suggested the presence of nitrates in abnormally high quantity in the
guts, indicating that not only the water but even the feed had turned
toxic in the area which was the home to these turtles.
After the
incident, environmentalists had raised a hue and cry over the issue,
and the Andhra Pradesh Pollution Control Board also promised to take
some measures to prevent a repeat of these deaths.
Olive Ridleys
migrate from the coast of Mexico to the Andhra Pradesh coast for
breeding and nesting each year between the months of November and March.
Many of them die along the Visakhapatnam coast after getting
trapped in the double-filament gill nets that are used by trawlers and
now pollution is another major problem. (ANI) -

Fish Kill In The Periyar River, India.
Allegations and counter-allegations continue to fly after yet another
fish kill was reported in the upstream of the Periyar river in Pathalam
recently. The Irrigation Department and environmentalists strongly
suspect industrial units situated nearby of dumping effluents in to the
river leading to frequent fish kills in the area.
However, the Kerala State Pollution Control Board has stuck to its
earlier claim that poor water flow in the Pathalam stretch resulted in
sudden drop in the dissolved oxygen level which led to the fish kill.
The Pollution Control Board had asked the Irrigation Department last
week to immediately lift the shutters at Pathalam to increase the water
level in the stretch.
M. S. Mythili, Chief Environmental Engineer of the board at Ernakulam,
said the dissolved oxygen level at Pathalam bund was 1.6 mg/litre. She
said aquatic life would be put under stress, if the oxygen level was
below 2 mg/litre.
Findings rejected
A senior official of the Irrigation Department, however, has rejected
the board’s findings. He pointed out that despite poor water flow in
Manjummel and Purapallikavu stretches of the river, fish kills were not
reported near these bunds.
“It is common sense that the industrial units near the Pathalam stretch
dump toxic effluents in to the river triggering fish kills. But board
officials do not confirm this as they do not want to receive the wrath
of the political leadership for being anti-industry,” the official said.
The Irrigation Department officials also clarified that the shutters
were downed for three days after the discharge rate from Bhootatankettu
dam came down considerably over the past few weeks.
Purushan Eloor, spokesperson of the Periyar Malineekarana Virudha
Samithi, supported the views expressed by the Irrigation Department by
stating that reduced levels of dissolved oxygen was a clear indicator of
high pollution in the Pathalam stretch.
Blaming the nearby industrial units for letting untreated effluents in
to the river, Mr. Purushan held the board responsible for not acting
against the violators.
“According to the board the dissolved oxygen level near the Pathalam
bridge where the fish kill happened is 4.7 mg/litre. This is above the
minimum limit prescribed by the board,” he said. -
