  abstract = {{B}oth in {I}ndonesia and {V}ietnam, larval rearing of #{P}angasius hypophthalmus$ remains problematic due to variable and generally low survival rates obtained. {T}he first week represents the most critical period for these larvae and up to now the cannibalistic behaviour was considered as the main cause of mortality. {I}n the present study, two experiments were carried out in order to better understand the evolution and causes of mortality of #{P}. hypophthalmus$ larvae from hatching up to 8 days of age and find out measures to improve survival rates. {T}he first experiment was designed to evaluate the importance of cannibalism and differences in mortality when larvae from two different females were reared either in groups of 30 individuals or in isolated conditions (30 larvae reared separately). {I}n both cases, the culture was carried out either with or without antibiotic. {T}he aim of the second experiment was to test {O}xytetracycline and different disinfectants ({C}hloramine-{T}, formalin and "formalin + {M}alachite {G}reen {O}xalate") at different dosges to prevent bacterial outbreaks in the culture. {T}he results indicated that the survival rates of #{P}. hypophthalmus$ larvae was dependant on the initial quality of larvae or eggs and that larval mortality was more a consequence of pathogenic infection than a direct effect of cannibalism. {T}he present study demonstrated that the survival rates of larvae were systematically improved when rearing as carried out in water containing antibiotic ({O}xytetracycline at a dose of 5 to 20 mg/{L}). {S}urvival rates and final mean body weights of larvae as high as those obtained using antibiotic were also reached with applications of disinfectants such as {C}hloramine-{T} and formalin. {T}he use of these disinfectants is recommended for an application in commercial #{P}. hypophthalmus$ hatcheries.
