ILOILO City: Western Visayas remains negative from
red-tide toxins, the Bureau of Fisheries and Aquatic Resources 6
(BFAR-6) said.
The BFAR issued the clarification
in the wake of several reported cases of red tide in Luzon and
Mindanao.
Red tide is a phenomenon caused
by algal blooms during which algae become so numerous that they
discolor coastal waters, hence the name red tide.
Since the 1980s harmful red tide events have become more
frequent and widespread.
Detection of a spread is thought
to be influenced by higher awareness of red tide, better equipment
for detecting and analyzing red tide and nutrient loading from
farming and industrial runoff.
Countries affected by red tide
include: Argentina, Australia, Brazil, Canada, Chile, Denmark,
England, France, Guatemala, Hong Kong, India, Ireland, Italy, Japan,
the Netherlands, New Zealand, Norway, New Guinea, Peru, the
Philippines, Romania, Russia, Scotland, Spain, Sweden, Thailand, the
United States and Venezuela.
