This research was conducted in 2019, in the waters of Lake Bandar Kayangan
Samar Valley subdistrict Rumbai Pesisir city of Pekanbaru Riau Province. This study

fish farming (KJA) compared to the Standard Quality of PP No.82 of 2001 and
analyze people activities around Bandar Kayangan Lake which led to the polluted
waters as a result of daily activities. The method used is an experimental method by
observing and measuring sample directly on rearing cages measure 1x1x1 m. Patin
fries were stocked at the age of two weeks with the number ( 50 fries ) and 3 months
time of rearing. Three units of cages 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 Kayangan is a waters that are so important for the life of people around
Lake Bandar Kayangan especially for fish farming in Keramba Floating Net (KJA).
