THE
Pambansang Lakas ng Kilusang Mamamalakaya ng Pilipinas (Pamalakaya) has
expressed alarm over the growing number of Chinese softshell turtles “invading”
Laguna de Bay, threatening the multimillion milkfish and tilapia industry
there.
Gerry
Albert Corpuz, public information officer of Pamalakaya, said these turtles,
scientifically known as Pelodiscus sinesis and first reported to have infested
fishponds in Region 3 (Central Luzon), have now reached the bay.
“They
[the Chinese turtles] are aggressive eaters. They grow fast and even move
faster than local turtles,” Corpuz said.
He
added that the Chinese turtles were reportedly as big as the pawikan or
Philippine sea turtle.
The
Pamalakaya official expressed fears that the turtles would adversely affect
fish-cage and fishpen operators, as well as small-scale fishermen, who depend
on the bay for their livelihood.
The
Chinese turtles are the latest non-native marine species to have invaded the
bay. Other non-native species like the janitor fish and knife fish have
competed with milkfish and tilapia for food there.
Officials
of the militant group saw how aggressive the turtles can be during a recent
dialogue with fishermen working at Laguna de Bay, where Pamalakaya Vice
Chairman Salvador France was shown a predatory turtle caught by fisherfolk from
Barangay Layunan in Rizal province’s Binangonan town.
According
to him, the turtle tried to attack one of the fishermen after it was released
in the bay.
In a
statement, France expressed dismay that government agencies are doing nothing
to prevent the Chinese turtles from multiplying in the bay.
“We
are just puzzled why officials of the Laguna Lake Development Authority and the
Department of Environment and Natural Resources [DENR] continue to play deaf on complaints [about] the
proliferation of predatory turtles across the 94,000-hectare Laguna de Bay.
They never report the presence of this predatory creature in Laguna Lake to the
general public,” he said.
Threatening
DENR
officials in Central Luzon earlier confirmed that
the turtles have proliferated in the region and threatening the milkfish and
tilapia industry there. In response, the department created a task force to
look into the distribution, feeding habits and reproductive features of the
turtles, which were introduced in the country in the 1990s.
The
officials fear that the continued proliferation of the turtles might adversely
affect rivers and streams, and seriously threaten the aquaculture industry in
Central Luzon.
Fishermen
and fishpond owners in the towns of Arayat, Candaba, San Luis, Minalin,
Macabebe and Apalit in Pampanga province likened the turtle menace to the
“golden kuhol” because of its adverse impact.
One
measure the officials are implementing to address the problem is catching the
turtles for local consumption. In Pampanga, three individuals were granted a
permit to collect a combined 36,820 heads of live turtles in 2013, or about
30,700 kilos of turtle meat.
In
2012 about 349,170 heads of live turtles, or 236,250 kilos of turtle meat, were
caught.
