EFISIENSI PEMANFAATAN PAKAN DAN PERTUMBUHAN LELE DUMBO (CLARIAS GARIEPINUS) STRAIN SANGKURIANG YANG DIPELIHARA PADA MEDIA DENGAN SALINITAS YANG BERBEDA DALAM KOLAM PLASTIK
ABSTRACT: The experiment to
determine the best salinity on media for the efficiency of use of Catfish
(Clarias gariepinus) strain Sangkuriang’sfeed and growth. Laboratory
experimental was used with various salinity variable were: 0 ‰ (as control), 1
‰, 2 ‰, 3 ‰, 4 ‰ and 5 ‰ with 3 repetitions for each. 3% for fish weight
feeding on twice a day at 8.00 am and 6.00 pm. The result of this research
showed that cultured at plastic pond media with different salinity do not have
an effects (p > 0,05) to feeding efficiency and daily growth rate of
Sangkuriang’s strain of lele dumbo (Clarias gariepinus var.), but it has a
significant effect (p<0,01) to absolute biomassa growth, feeding conversion
and survival rate. Cultured Sangkuriang’s lele dumbo in plastic pond could be
efficiently conducted at media’s salinity up to 5 ‰, but by significant notice
at frequency, type and nutritional composition of feeding and also controlling
the water quality. The most appropriate optimal salinity value, based from
growth of compensation for the rearing of consumption size, is 4 ppm. The water
quality showed on supporting life of lele dumbo lele’s cultured in plastic
pond.
