Butuan City – The Bureau of Fisheries and Aquatic Resources (BFAR) on Saturday reminded Surigaonons that the red tide alert remains raised over Lianga Bay in Surigao del Sur province following the findings of the agency late last year that all types of shellfish taken from this bay were unsafe to eat.

In a red tide latest advisory issued February 15, BFAR said recent laboratory tests showed that shellfish collected from Lianga Bay still contained “paralytic shellfish poison” beyond the regulatory limits.

The waters of Lianga Bay cover the towns of San Agustin and Marihatag, both of Surigao del Sur province.

The red tide warning pointed out that all types of shellfish and Acetes specie, commonly known as “alamang,” gathered from the area are not safe for human consumption.

Red tides are caused by an explosive growth and accumulation of certain microscopic algae, predominantly dinoflagellates, in coastal waters.

Some species of dinoflagellates produce toxins that are among the most potent known to man.

These harmful algae blooms, or HABs for short, pose a serious and recurring threat to human health, wildlife, marine ecosystems, fisheries, coastal aesthetics and the economy.
