ABSTRACT : The purpose of the
this study was to study the effect of the use of freshwater barn
(Pilsbryoconcha exilis) to water quality improvement and growth rate
lele sangkuriang. This study used Completely Randomized Design with four
treatment and three replications. The study used different animal counts
Freshwater barn is 100, 150, 200
tail / basket measuring 0.6 m3 and control treatment ie without using
treatment of recirculation systems and without the addition of fresh water gulls. Parameter
The main research in this study is the growth of fish and ammonia concentration,
with supporting parameters such as temperature, pH, and dissolved oxygen.
The results showed that the addition of freshwater barbecue had an effect
on growth and survival of sangkuriang catfish. Growth
the highest absolute is in the treatment of 200 individuals weighing 19.71 g and
the highest survival rate was treated by 200 individuals (80.14%).
The results also show that the addition of fresh water barn with
Different amounts have a marked effect on ammonia reduction.
Based on the results of the least significant difference (BNT) with the addition
a freshwater barn of 200 heads / baskets measuring 0.6 m3
best treatment in ammonia decrease in recirculation system

Kata key : catfish sangkuriang, biofilter, freshwater bar, growth, continuity
