Abstract

• The present work was investigated the growth performance of post-larvae Notopterus notopterus by using three different diets. A total of 300 post larvae, ranging from 2.9 cm to 3.4 cm in length and weighing between 0.02 g and 0.05 g, were divided into three groups and fed with three different live feeds: Moina, Tubifex, and Rotifer. The experiment were conducted for three triplicate. The fishes accepted all types of diets. The specific growth rate (SGR) was higher in post larvae fed on Moina (6.98±0.10%), followed by Tubifex (6.92±0.04%), with the lowest SGR was recorded for Rotifer (6.74±0.44%). The highest final mean weight and weight gain were observed in post larvae fed on Moina (2.64±0.16) g, followed by Tubifex (2.54±0.06) g, with the lowest weight gain recorded for Rotifer (2.30±0.31) g. No significant difference was observed in fish fed on Tubifex and rotifer, whereas Moina-fed larvae showed a significant difference (p < 0.05) compared to other two groups. The survival rate on day 60 was 83% for larvae fed on Moina and 82% for those fed on Rotifer, whereas the lowest survival rate of 75% was recorded for Tubifex fed larvae. Therefore, The larvae of Notopterus notopterus could be reared using different livefood to promote enhanced growth and survival rate.
