FREKUENSI PEMBERIAN PAKAN DAN KONDISI PEMELIHARAAN BERBEDA TERHADAP LAJU PERTUMBUHAN LELE DUMBO (Clarias gariepinus)
ABSTRACT: The aim of this
study were to select the best frequency of feeding and tank background of dark
and light on the growth and survival rate for African catfish (Clarias
gariepinus). Thirty six aquaria in size 50 x 40 x 40 cm with 30 cm water height
were used in this experiment and completed with water aeration. The object of
study was African catfish, with total length ranges from 8.0 to 9.6 cm and
weight from 11.78 to 13.79 g. The treatments consisted of two factors: the
frequency of feeding and tank background conditions with 6 replications.
Feeding frequency were 3 levels: 3, 4 and 5 times (F3, F4 and F5). Tank
backgrounds were 2 levels: Dark (K1) and Light (K2). Fish were reared up 30
days. The results showed that the the best rate of increase in specific weight
occurred in the treatment of conditions of maintenance of light with a
frequency of feeding 5 times (5.21%). Specific growth rate (SGR) African
catfish (Clarias gariepinus) best occur in conditions of maintenance the light
with the frequency of feeding 3 times (1.53%). Survival (SR) maintenance of the
highest in bright conditions with feeding frequency 5 times (70%) and not
significantly different (P> 0.05) with the condition of dark maintenance
with feeding frequency 3, 4 and 5 times (each 70 %).
