were placed at each station that has been determined and Rumbai Freshwater Cultured
Installation pond as control. Data were analyzed descriptively and statistically, the
descriptive analysis performed on physical and chemical parameters of water based on PP
No. 82 year 2001 and was associated with the growth and survival of Patin fry. Statistical
analysis is using Analysis of Variance ( ANOVA ) and completely randomized design (
CRD ) with treatment of 3 times repetition. Growth and survival of Patin fry on each
station were quite well where the average growth of absolute weight between 35.43-36.20
grams, the average growth rate of daily weight between 5.602-5.782%, the average of
absolute growth inlength between13,61-14.10 cm, the average of daily growth in length
between 2.285 - 2.321% and the survival rate between56-79%. The waters of Lake Bandar
