Red tide is caused by an alga Alexandrium fundyense, which produces a toxin that can cause paralytic shellfish poisoning (PSP).

Meanwhile, the Philippines Bureau of Fisheries and Aquatic Resources (BFAR) has reassured fishermen and the public that seafood from the coastal waters of Alaminos City, Anda, Bolinao and barangay Wawa in Bani are safe to eat, as the waters remain red tide free.

In aquaculture news, a new study from The Freedonia Group predicts that global demand for aquaculture supplies and equipment is expected to moderate, growing 7.4 per cent per year to $63.6 billion in 2017 at the farm gate level.

The ongoing transition from extensive and semi-extensive to intensive aquaculture production will support greater feed demand, and rising feed costs will drive advances in market value as fish meal and fish oil prices continue to grow rapidly.

Measures have now been taken in Brazil to protect the environment against aquaculture fish waste. Two plants in Jaguaribara and Morada Nova now convert tilapia waste into biodiesel.
