As a part of an ongoing monitoring study of phytoplankton in Yemeni coastal waters, phytoplankton samples were collected from November 2012 to September 2013 at four sampling locations along the coast of Hodeida City, southern Red Sea. A bloom of toxic dinoflagellate Pyrodinium bahamense var. bahamense Plate was observed in August 2013. The population density of P. bahamense were ranged from 1.6 × 10 4 to 3.3 × 10 5 cell L -1 (accounting for 41.8 % of the overall phytoplankton community). This finding is the first observation of vegetative cells of this tropical species from the Red Sea. Water temperatures during the bloom was 32°C and salinity was 37 psu, indicating its tropical and subtropical nature. Among the phytoplankton species reported during this study, the red tide-forming species; Trichodesmium erythraeum (14.1%), Protoperidinium quinquecorne (6.3 %) and the known toxic species, Dinophysis caudata (1.4 %), and D. acuminata (1.00 %) were remarkable. It is apparent from our results that the toxic species do occur during many months of the year in the Coastal Waters of Yemen with high abundance observed in August followed by April 2013. Further studies are required to carry out the HAB monitoring for preventing the risk of HAB events that may outbreak in future at the Red Sea coast.

“…One example is Pyrodinium bahamase, which also causes PSP outbreaks but occurs predominantly at low latitudes in the tropics (e.g. Usup et al 2012). I hypothesize that dormancy transitions in P. bahamase cysts may also be sensitive to chilling, but the threshold temperature (T max ) below which chilling would be accumulated, would be warmer to reflect their habitat.…”

A field survey was carried out in Aman Island, the northern Strait of Malacca, to investigate the occurrence of harmful microalgae. The area is known for marine finfish cage-culture and blood cockle farming. Plankton samples were collected fortnightly between July 2011 and September 2013. A total of 58 phytoplankton genera were recorded; 37 belong to the diatoms, and 21 genera were dinoflagellates. Harmful microalgae species were identified microscopically, of which nine are bloom-forming species that responsible for fish kills. These included Akashiwo sanguinea, Chaetoceros affinis, Cha. curvisetus, Cha. laevis, Ceratium furca, C. fusus, Cochlodinium sp., Karlodinium australe and Noctiluca scintillans. Three Alexandrium species were identified from the samples, i.e. A. leei, A. affine and Alexandrium sp. Pulau Aman; some species in the genus have been known to associate with Paralytic Shellfish Poisoning (PSP). Diarrhetic Shellfish Poisoning (DSP)-toxin producers were also encountered in the water samples, viz. Dinophysis acuminata, D. caudata, Dinophysis sp. and Prorocentrum micans. The harmful diatom, Pseudo-nitzschia spp. that associated with Amnesic Shellfish Poisoning (ASP), was commonly found in the water samples. Cell abundance of each harmful microalga was enumerated. The results showed that cell densities of harmful microalgae were relatively low throughout the sampling period. The microalgae community was dominated by Ceratium furca in May 2012, with cell densities exceeding 70,000 cells L-1; no fish kill event was reported during the time. Even though no fish kill or shellfish poisoning was reported in the area, he presence of harmful microalgae albeit at low cell densities, may pose a potential threat to human health and seafood biosecurity. Therefore, regular phytoplankton monitoring is necessary to safeguard human health and seafood industries in the country. Aman Island, an island in the northern part of the Straits of Malacca, is a very important marine finfish (grouper, snapper and sea bass) aquaculture area and blood cockle farming. In 2012, it produced 1.8 × 10 3 tonnes of marine fish valued RM 18.26 million (Department of Fisheries Malaysia). To date, there has been very limited baseline data on the occurrence of harmful algal bloom (HAB) in the waters surrounding Aman Island.
