RED TIDE scare is common so we must keep ourselves updated about its occurrence.
“Red tide” is a term often used to describe HABs in marine coastal areas, as the dinoflagellate species involved in HABs are often red or brown, and tint the sea water to a reddish color. The more correct and preferred term in use is harmful algal bloom, because: 1. these blooms are not associated with tides 2. not all algal blooms cause reddish discoloration of water 3. not all algal blooms are harmful, even those involving red discolouration.
Bureau of Fisheries and Aquatic Resources is regularly publishing RED TIDE ALERT, the Shellfish Bulletin. Results are based on their thorough laboratory testing.
