Abstract/ Executive Summary:

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.

Start Date: 20-12-2010

End Date: 15-02-2011

Program Area: Animal Health and Management

Commodity: Carp fish

Objectives:

To find out the proper feed (protein level) for larval growth and survivability of comet goldfish (Carassius auratus) larvae in the congested fiber glass aquaria.

Methodology:

The experiment was conducted for 60-day long from 20th December, 2010 to 15th February, 2011 in fiber glass aquaria volume (30×11×8 inch³) in the fish physiology laboratory of Fisheries and Marine Resource Technology Discipline, Khulna University, Bangladesh. In this experiment there were three treatments and each treatment consisted of two replications supplied with three dissimilar feeds i.e. treatment T₁ (crushed pellet feed), treatment T₂ (mixed diet i.e. 50% pellet + 50% chopped tubificid worms) and treatment T₃ (live chopped tubificid worms). Each of the experimental units of 45 larvae was stocked and their average length were 2.21 ± 0.03, 2.23 ± 0.04 and 2.25 ± 0.05 mm respectively in three treatments and their average weight was 0.005 ± 0.001 g respectively. PG dose was used for artificial propagation of the brood fish for production of larvae. Then the larvae were reared in the glass aquaria up to three days and nourished along with boiled eggs for avoiding biasness of outcome. Prior to storing of larvae, each of the fiber glass aquaria was prepared of dirt free up and equipped with all conveniences so that the experimentation runs sound powerfully. About 50% water from each aquarium was partially substituted through hygienic water at every alternate day before feeding. Appropriate aeration was done to supply adequate oxygen into the aquaria by motorized aerator it was nonstop till the conclusion of the research. The feces in each aquarium were removed by siphoning and the dead larvae were removed and reckoned in the morning and in the evening prior to feeding. Proximate composition of feeds were examined following the standard methods given by Association of Official Analytical Chemists in the Fish Nutrition Laboratory of Fisheries and Marine Resource Technology Discipline, Khulna University, Khulna. The larvae stocked under the different treatments were fed with different feeds administered those three times daily at 7:00, 3:30 and 12:300 h. Sampling was made at every 7 days interval. Ten larvae were arbitrarily collected from each aquarium to obtain the length and weight data. The weight (g) was taken in an analytical balance and the length (mm) was measured by placing the fry on a transparent petridish placed on a 1 mm graph-paper. Sampling was done before the application of feed to avoid the biasness of weight due to presence of excessive feed. The following formulae were used to determine the different growth parameters. Statistical Analyses: Spread sheet analysis of data was done by using Microsoft Excel, version 5.0, Microsoft Inc. USA. To analyze the data analysis of variance (ANOVA) followed by Duncan’s Multiple Range Test (DMRT) was done by using SPSS 16.0 for windows®. Standard (± error) of treatments means were calculated from the residual mean square in the analysis of variance.

Achievement/Findings:

The available information suggests that the survival rate is very poor in earlier stage of the life cycle. In treatment T₁ the survival rate was lower than that of other two treatments because, pellet feed was used in treatment T₁ which deteriorated the water quality much than other two treatments. This result may be due to poor physiological development of earlier stage of life.
