Abstract
200 fry of carp obtained from induced breeding by stripping were fed three times daily ad libitum with Artemia (DT1), commercial starter diet (DT2), and dried egg yolk (DT3)for 8 weeks. Each treatments were in triplicates in indoor hatchery. At the end of the experiment, the progenies mean weight gained (MWG) was highest in the treatments fed Artemia (3.490±0.015a) as compared to others with significant difference (P<0.05).Mean weight gained (MWG) was highest in the treatments fed Artemia. Percentage weight gain (%WG) and specific growth rate (SGR) had no significant differences (P<0.05). Feed conversion ratio (FCR) was highest (P<0.05) in treatment fed with smashed egg yolk. Feed conversion efficiency (FCE) was highest (P<0.05) in the treatment fed with composed feed. Mortality rate was highest in treatment fed with Artemia, and percentage survival was highest (P<0.05) in treatment fed with composed feed. Percentage jumpers per treatment were highest in Artemia diet. In conclusion, it is imperative that Artemia feed (amidst other starter diets researched on) is most preferable for the optimum growth and development of common carp fry.
