Marine zooplankton researches in Vietnam: An overview

Marine zooplankton in Vietnamese waters have been studied since the establishment of the Institute of Oceanography in 1923. A total of 253 species of zooplankton have been reported from the Gulf of Tonkin, with the biomass (wet wt) of about 72mgm(-3) on average, which was higher than any other coastal waters of Vietnam. Vietnamese coastal waters from Hue to the Ca Mau Cape have been studied mainly by the Institute of Oceanography, Nha Trang. After the liberation of South Vietnam in 1975, many comprehensive investigations have been conducted in South Vietnamese waters, reporting 211 zooplankton species and the seasonal changes of biomass with peaks in September-December. The Gulf of Thailand was studied in 1979 and 1982-1994, wherein 125 zooplankton species were reported from the coastal waters of Minh Hai and Kien Giang Provinces. The species number of zooplankton was generally higher in the southern than in the northern waters while the biomass was higher in the northern waters.Proceedings of the Horiba International Conference "New Direction of Ocean Research in the Western Pacific" : Past, Present and Future of UNESCO/IOC/WESTPAC Activity for 50 years and the JSPS Project "Coastal Marine Science"Section II: Historical Review of Coastal Research in Southeast Asi
