Temporal and spatial distribution of harmful algal bloom (HAB) species in coastal waters of Kota Kinabalu, Sabah, Malaysia

Development of harmful algal blooms (HABs) in coastal waters of Kota Kinabalu, Malaysia, is a recurring problem. The blooms are caused by Pyrodinium bahamense var. compressum and Cochlodinium polykrikoides. Recently, another potential HAB species, Gymnodinium catenatum, was identified. The occurrenc...
