Research data would provide the necessary information for the exploitation, fi sh farming and protection of fi sh resource in local area. Fish samples were collected periodically twice each month by fi shing gears and buying from fi shermen at 4 capture locations in My Tho. Taxonomy of fi shes was mainly based on orphological methods following published fi sh taxonomy documents. The results showed that there were 56 species of fi sh (belonging to 29 families of 11 orders) to appear in 2018 in My Tho. The Perciformes order had the largest number with 15 species (26.79%) of 10 families (34.48%). Siluriformes order had 8 species (14.29%) of 6 families (20.69%). Gobiiformes order had 8 species (14.29%) of 3 families (10.34%). Especially, Cypriniformes order only had one family but it's species composition was very diverse with 14 species (25%). Besides, the result showed that other orders of fi sh had from 1 to 3 species (1.79-5.36%) and ranged from 1 to 3 families (3.45-10.34%). Moreover, there were some species of brackish water fi sh to appear in water bodies in My Tho at the period of salinisation.
