PERTUMBUHAN DAN EFISIENSI PAKAN IKAN NILA (OREOCHROMIS NILOTICUS) YANG DIBERI PAKAN BUATAN BERBASIS KIAMBANG
Abstrak: The specific
objective of this study was to determine the growth and feed efficiency in
tilapia (Oreochromis niloticus) fed artificial diets based kiambang that has
been fermented with Rhyzopus oryzae. This research are done in May and November
2014, using a completely randomized design. Treatments are different stocking
density is 50 individual / m2 (A), 75
individual / m2 (B), and 100 individual / m2 (C). The results showed: the
highest relative growth rate in treatment C for 898,0g / individual, followed
by treatment B for 679,25g / individual and A of 455,83g / individual. Feed
efficiency ranged between 89.65% - 90.26%. The survival rate of tilapia during
the maintenance period is 100%. Results of water quality analysis showed decent
range for the life of tilapia where the temperature ranges from 26 ° C - 28 °
C, the degree of acidity (pH) ranged from 7.10 to 7.27, and dissolved oxygen
(DO) ranged from 3.5 to 4.1 mg / l.
