Abstract/ Executive Summary:

Experiment was conducted to evaluate the effects of an organic fertilizer and supplementary feeds on the growth performance of silver carp (Hypophthalmichthys molitrix ) and bata (Cirrhinus reba) fry for a period of 90 days.It was carried out under 3 (three) treatments were consisted of mustard oil cake (T₁), cow dung (T₂) and rice bran + mustard oil cake (T₃) with each three replications. The fries were initially fed at the rate of 30% of body weight and it was reduced to 15% gradually. The rate of cow dung application was 988 kg/ha. During the experimental period, the water parameters were in suitable range.The average weight gain of silver carp and bata in T₃ (4.69±0.17 g and 2.05±0.08 g) was significantly ((p<0.05) higher than those of T₁ (3.00±0.16g and 1.81±0.02 g) and T₂ (2.32±0.09 g and 1.19±0.13 g). The survival rate was found significant 59.12, 55.05 and 63.33 % for Silver carp and 52.15, 51.10 and 55.18 % for bata in T₁, T₂ and T₃ respectively. The SGR of silver carp and bata in T₃ (2.55±0.43%bwd^-1and 2.29±0.08%bwd^-1) was significantly ((p<0.05) higher than those of T₁ (2.32±0.46%bwd^-1 and 1.95±0.47 %bwd^-1) and T₂ (1.91±0.40 %bwd^-1 and 1.72±0.28 %bwd^-1). Among the treatments, significantly highest production of Silver carp and Bata(2276.01±85.95 and1855.38±35.95 kg/ha)was achieved from T₃ followed by T₁ (2116±6.72 and 1745.98±12.31 kg/ha) and T₂ (2058.48±26.68 and 1432.82±16.82 kg/ha).

Commodity: Aquatic animal

Objectives:

To serve the growth performance, Survival rate and Specific growth rate of Hypophthalmichthys molitrix and Cirrhinus reba in nursery ponds.

Methodology:

Study Area and Experimental Design: The research was carried out for 60 days from 12th August to 11th October, 2012 in nine experimental ponds,Department of Fisheries, University of Rajshahi, Bangladesh. The ponds were rectangular in shape and the surface area of each pond was 0.0024 hector with an average depth of 1 meter. The ponds were well-exposed to sunlight and sandy loam bottom soil types and dependable on rainfall and deep tube well water. The present experiment was conducted with three treatments viz. T₁ (Mustard oil cake), T₂ (organic fertilizer: Cow dung) and T₃ (Mustard oil cake + Rice bran) each with three replications. Pond Preparation, Stocking and Fertilization: Before starting the experiment the ponds were dried and freed from aquatic vegetation. After drying liming (CaO) was done in all the ponds at rate 1 kg/decimal. Ponds were then filled with ground water at a depth of about 1 meter. In treatment T₂ only cow dung was applied (988 kg/ha) as basal dose.After five days, aquatic insects and predatory zooplankton were eradicated by applying sumithion (100ml/deci). After seven days, Fry of silver and Bata were stocked early in the morning in all the ponds at the density of 123500 Silver carp and 123500 Bata per hector. All the fry were collected from private nursery operator in Rajshahi district. Only treatment T₂ fertilized with cow dung (988 kg/ha) which was done weekly.In treatment T₁ the stocked were fed only with rice bran and in treatment T3 stocked were fed with rice bran and mustard oil cake twice daily (morning 7-8 am and afternoon, 4-5 pm). The fish were initially fed at a rate of 30% of their body weight for the first fortnight and 20% of their body weight for the second and third fortnight and gradually reduced to 15% of their body weight for the last fortnight. To estimate the growth of fish, 10% fries from each treatment were sampled fortnightly to monitor the fish growth and to adjust feeding rates. Study of Water Quality Parameters: Different physico-chemical parameters of pond water were recorded fortnightly throughout the experimental period between 10 A.M. and 12 A.M. Physical parameters such as; water temperature (°C), transparency (cm) were measured at the pond site on every sampling day.Water transparency of the experimental ponds was measured by a Secchidisk in cm. Water temperature was recorded with a Celsius thermometer at 15-20 cm depth. The dissolved oxygen concentration of water was determined by the aid of a water quality test kit (HACH kit model FF-2, made in USA).pH of water was measured by using HACH kit (model FF-2, cat. No. 2430-01, made in USA) and nd total alkalinity of water sample was determined by titrimetric method using methyl orange indicator. Ammonia-Nitrogen was measured by using a HACH kit (model FF-2, cat. No. 2430-01, made in USA). Rochelle salt solution and Nessler reagent were used to measure the NH₃-N. A colour comparator (value ranging from 0 to 3.0 mg/I) also used for the same. Harvesting of Fish: At the end of the experiment the water of the ponds were pumped out and all the fishes were harvested. Then the final growth gained by the fishes was recorded by measuring the length (cm) and weight (g) of the harvested fishes by using a measuring scale and a balance respectively. Estimation of Survival Rate, Growth and Production of Fish: The following parameters were used to evaluate the growth performance of fry under different treatments. Length Gain: Length Gain (cm) = Average final length – Average initial length Weight Gain (g) Weight gain was calculated by the following formula and it was expressed as g. Weight gain (g) = Mean final weight (g) - Mean initial weight (g) Specific Growth Rate (% per Day): The specific growth rate was calculated. Survival Rate (%): At the end of the experiment, the fishes were harvested and the survival rate was calculated. Production (kg/ha/60 Days): Yields were calculated by deducting biomass at stock for biomass at harvest and it was expressed by kg/ha/60 days. Statistical Analysis: Data of water quality, growth, survival rates (%) and fish production were subjected to using one-way analysis of variance (ANOVA) and tested Duncan’s New Multiple Range Test (DMRT, 1955) to identify significant differences among the mean values at 0.05% level. This statistical analysis was performed with the support of the computer software SPSS (Statistical package for social sciences, version 16) program.

Achievement/Findings:

The end of experiment net production of Bata ranges from 1099.17±34 to 1568±13.93 kg/ha/56 days and from the study, it is clear that the growth of silver carp and batafry is faster by using supplementary feed (Rice bran+ Mustard oil cake) in T₃.
