Philippines to fight invading species
PHILIPPINES: Like some bad science-fiction movie, Philippine
fishermen are encountering strange alien creatures: tough, speckled fish
with sharp spines that tear and rip their nets.
These suckermouth catfish from South America are just one of a
growing number of foreign species that are spreading in local waterways
and forests, threatening to edge out the country's indigenous plants and
animals.
The catfish, locally known as "janitor fish", were originally
introduced locally for aquariums but careless handling and weak controls
allowed them to escape into the wild - just like scores of other animals
and plants.
These foreign species may look like cute turtles or lovely flowers
but Government wildlife experts warn that they are displacing native
plants and animals while causing massive harm to the farming and fishing
industries.
"The ecological threat of invasive species is so great, they could
transform the landscape, wipe out native species and destroy the
diversity of the ecosystem," said Government wildlife specialist Anson
Tagtag. In the case of the suckermouth catfish, it has multiplied faster
than local species while competing with them for food and building nests
in mud banks, dirtying the waters.
Filipinos generally find janitor fish unpalatable so those that are
caught by fishermen go to waste. MANILA, Wednesday, AFP
