Abstract

The research work was carried out for 60-days with the aim of examine the effects of different feeds on larval development and survival of 3 day-old comet gold fish Carrasius auratus larvae in closed fiber glass aquaria to build up nurturing routine for supporting the aquarium business. Six experimental units were consisting three treatments, each comprising of two replications and stocked with 45 larvae. Initial length were 2.21 ± 0.03, 2.23 ± 0.04 and 2.25 ± 0.05 mm respectively in three treatments and weight of larvae was 0.005 ± 0.01 g and the volume of each glass aquaria was 30 × 11 × 8 inch3. Three different feeds i.e. crushed pellet feed, mixed diet i.e. 50% pellet +50% chopped tubificid worms and live chopped tubificid worms, having different protein levels were administered to compare their suitability as food for nurturing of C. auratus larvae. The larvae fed with chopped tubificid worms showed significantly better results in terms of length and weight gain, percent length and weight gain and specific growth rate (SGR %) compared to the rest two treatments. The highest survival rate 64.64 ± 2.46% was shown by the chopped tubificid worms fed larvae which was significantly higher than those of crushed pellet feed and mixed diet respectively. Water quality parameters were monitored throughout the experimental periods. On the basis of larval growth and survival rate, it could be suggested the live chopped tubificid worms is suitable for the nurture of comet gold fish C. auratus larvae.
