One of the main problems that has to be faced by Pangasius hypophthalmus breeders is the high mortality of the larvae, which can be a consequence of both cannibalism and bacterial diseases. The aim of this study was to explore the possible sources of Aeromonas hydrophila that may result in an infection of Pangasius hypophthalmus larvae. Isolation of bacteria was made from water source, Artemia culture medium, Artemia nauplii used as feed, ova (unfertilised eggs), sperm, and fed as well as unfed larvae that were collected every day from hatching, up to the age of 7 days. Characterisation of bacteria was done on the basis of morphological, physical and biochemical characteristics. The serological method of identification using polyclonal Aeromonas hydrophila antiserum was used. The results indicated an absence of bacteria from sperm. By contrast, bacteria Alcaligenes sp. were isolated from source of water, unfertilised eggs and from 1-day-old larvae. Proteus sp. were isolated from the 1st day of age in fed larvae and from the 7th day in unfed larvae. Aeromonas hydrophila were isolated from larvae of 2 days of age, and Aeromonas punctata from 2-days-old unfed larvae, meanwhile Plesiomonas shigelloides were identified from fed larvae of 2 and 4 days of age, and from 2-days-old unfed larvae.
