| Summary: | This study was carried out to determine the suitability and efficacy of the growth performance and survival rate of rohu (Labeo rohita) for a period of 63 days in the Wet Laboratory at Department of Aquaculture, BAU, Mymensingh. Four treatments were considered having three replicatescontaining different percent-age of prebiotic (potato) in the diet viz.T1(0%), T2(5%), T3(10%), T4(15%). Initial weights of 1.74 ± 0.0 g were released at rate 15 fingerlings per aquarium. The result showed that the best weight gain of 2.73 ± 0.40 g wasobserved in T4.Weight gain (g), %weight gain and SGR (%per day) varied from 1.29 ± 0.25 to 2.73 ± 0.40; 74.32 ± 14.17 to 157.01 ± 22.77 and 0.38 ± 0.06 to 0.65 ± 0.06, respectively. Survival rate were 97.78 ± 2.22%, 100%, 100% and 100% in T1, T2, T3and T4, respectively. Values of FCR, FCE and PER were varied from 2.12 ± 0.22 to 3.49 ± 0.47; 0.29 ± 0.04 to 0.48 ± 0.05, and 0.68 ± 0.09 to 1.09 ± 0.11, respectively. The highest FCR (3.49 ± 0.47) was found in T1and lowest FCR (2.12 ± 0.22) was found in T2. The highest PER (1.09 ± 0.11) was found in T2and lowest PER (0.68 ± 0.09) was found in T1. The research findings suggested that supplementation of 15% potato containing diet which could be chosen by fish feed manufacture and fish farmers. |
