Abstract:
This study was carried out to determine the effects of egg custard on growth and
survival rate of patin bunga (Pangasius sutchi) larvae. Two days old larvae (6 to 7 mm)
were reared for 36 days in 20 L aquarium which filled with 15 L water. The stocking
density was 20 larvae L-1• Three replicates were done for each treatments and control.
The result showed that larvae fed with egg custard showed the lowest growth rate that
were 0.01225 g ± 0.79 for total increment of wet weight and 15.851 mm± 0.768 for
total length. The highest growth rate shown by larvae fed with mixed diet ( egg custard
and control diet) that were 0.03062 g ± 0.00017 for total increment of wet weight and
23.583 mm ± 1.091 for total length followed by control (Artemia, Moina sp. and
commercial pallet), 0.02632 g ± 0.00073 for total increment of wet weight and 21.413
mm± 0.79 for total length. For survival rate, larvae fed with egg custard give the lowest
percentage that was 38 % followed by larvae fed with mixed diets (72 %) and control
give the highest percentage that was 85 %. From the proximate analysis, egg custard
gives the lowest level of nutritional value that were 34.32 % protein, 6.81 % crude lipid,
12.47 % of moisture and 11.05 % ash. There were significant different between
treatment and control for wet weight and survival rate where p< 0.05 meanwhile no
significant different in total length (p>0.05).
