Abstract
A study on adaptation and growth of 10 days old larvae and 21 days old juvenile of Patin
bunga, Pangasius sutchi in different salinity was conducted. For adaptation by direct
exposure experiment, 10 days old larvae and 21 days old juveniles were used, while
adaptation and growth studies by gradual acclimatization process, IO days old larvae
were used. Salinity used ranging from O ppt, 5 ppt, IO ppt, 15 ppt, 20 ppt, 25 ppt, 30 ppt
and 3 5 ppt. The result showed that the maximum salinity tolerance by direct exposure for
10 days old larvae was l 3ppt while for 21 days old juvenile was 16 ppt. By gradual
acclimatization process, the larvae were able to adapt until 12 ppt. There was no
significant difference in the interaction effect between size factor and salinity tolerance.
There was also no significance difference in the interaction effect between growth factor
and salinity concentration (p>0.05).
