|One of the most famous fish’s families for consumption in Chattogram coast is Cynoglossidae and Dasyatidae family but no such work was done on this specific family in this coast before. So, variations among different species under the Cynoglossidae and Dasyatidae family was investigated using morphometric characters. A detailed one year (February 2019 to January 2020) long survey considering 2 months of ban periods (June-July 2019) was done for checking out the available Cynoglossidae and Dasyatidae in the Chattogram coast, including three stations. Two stations in Chattogram metropolitan area (Patenga and Kattoli) and one in Cox's Bazar. Morphometric data collected from the survey went through the statistical analysis of correlation. In total, seven species under the Cynoglossidae and Dasyatidae family could be able to find out. After every sampling, initially samples were sorted into different group on the basis of visual examination, then the morphological process confirmed species of different sorted group. From every sample, six morphological data (length) was collected for statistical analysis. A detailed morphological study to differentiate among closely related species was the study's basis. The frequency of availability of Cynoglossus lida and Himantura walga were the most among the species both in stations and months.Some species such as Cynoglossus macrolepidotus, pseudorhombus elevatus, Paralich algoeusis, Dasyatis bennettis, Gymnura poecilure were found less frequently. Within species, all species were correlated. Cynoglossidae and Dasyatidae family might influence the environment, the economy because of being the diverse fish family, and this study was an initial step towards this process. Further scientific experiment on Cynoglossidae and Dasyatidae family can use this study as baseline experiment. KEYWORDS: Morphometric, Cynoglossidae and Dasyatidae, Availability, Chattogram.
