Effect of artificial feed on the growth and survival of white shrimp (Litopenaeus vannamei) and milkfish (chanos chanos) in application of innovative polyculture technology

The objective of this research was to investigate growth and survival of white shrimp (litopenaeus vannamei) and milkfish (chanos chanos) in the application of innovative polyculture technology. the material in this study was white shrimp with initial weight of (1.25 ± 0.025) g and milkfish of (3.25 ± 0.075) g,respectively and artificial feed containing 35% of protein enriched with vitamin c (3% biomass d-1). completely randomized design was used with four treatments and three replications,i.e. t1 (15 individuals of white shrimp per m2 and 15 individuals of milkfish per m2),t2 (30 individuals of white shrimp and 15 individuals of milkfish per m2),t3 (15 individuals of white shrimp and 30 indviduals of milkfish per m2),t4 (30 individuals of white shrimp per m2 and 30 indviduals of milkfish per m2). absolute weight of growth,survival,fcr,and water quality data (temperature,salinity,ph,o2,no2,nh3) were analyzed by analysis of variance (f test) and descriptive analysis. the results elucidated significant effect (p < 0.05) on the growth and survival rate of white shrimp and milkfish. the highest absolute growth weight of white shrimp and milkfish were obtained from t4 treatment i.e (19.25 ± 1.015) g for white shrimp),for milkfish (185.71 ± 1.025) g. survival rate of white shrimp was 95% ± 2.5% and for milkfish was 75% ± 2.75%. © 2016 penerbit utm press. all rights reserved.
