INFLUENCE OF FEEDING TIME ON FEED UTILIZATION BY SIAMESE CATFISH, Pangasius hypophthalmus JUVENILE
Abstract: Siamese catfish
(Pangasius hypophthalmus) at juvenile stage is used as ornamental fish by fish
hobbies because of their beautiful shape and movement. Feeding time is a part
of feeding management to get the best and effective strategy on feed input.
This study aimed to determine the growth of Siamese catfish juvenile by looking
at the influence of feeding time on feed utilization. The average individual
weight of juveniles used was ± 3.2 g stocked 15 fish per aquarium equipped with
recirculation system. Two level factors in the factorial design consisted of 4
feeding times (at 8:00, at 12:00, at 16:00, and as control (8:00, 12:00, 16:00)
and feeding level (45 g feed kg-1 fish, 90 g feed kg-1 fish). Interaction
between feeding time and feeding level resulting eight types of treatments
research, namely A (8/45), B (12/45), C (16/45), D (8:12:16/45), E
(8:12:16/90), F (8/90), G (12/90), and H (16/90). The results showed that
feeding time had significant effect on the specific growth rate, feed
conversion, and protein efficiency ratio and were significantly different among
the treatments (P<0.05). Besides feeding time control (treatments D and E),
treatment C also showed the highest of specific growth rate (2.03%), protein
efficiency ratio (1.46), and the lowest feed conversion ratio (1.85).
