IDENTIFYING THE CENTRIC DIATOM COSCINODISCUS SPECIES AT COASTAL AREA IN DONG HAI ESTUARY, DUYEN HAI DISTRICT, TRA VINH PROVINCE
Main Article Content
Abstract
This article used a morphological classification method to identify phytoplanktonic species of the genus Coscinodiscus. That is through specific structures and details on the silicon frustule of the diatom cell. Planktonic samples were collected samples at 4 sites belonging to coastal area of Dong Hai estuary, Duyen Hai district, Tra Vinh province in July 2020. Species were determined and described based on structural details on valve such as central situation, areola form, arrangement of areola. A total of 15 species were recorded, they were classified into 3 types of groups, in which the Lineati type includes C. bipartitus, C. eccentricus and C. lineatus; there are three species in the Fasciculati type including C. curvatulus, C. rothii and C. subtilis; and the Radiati type comprises species such as C. asteromphalus, C. gigas, C. jonesianus, C. nodulifer, C. marginatus, C. oculus-iridis, C. perforatus, C. perforatus var. pavillardii and C. radiatus. In addition, descriptions of each species were presented in detail based on observations and photographs of the cell frustule.
