Abstract/ Executive Summary:

The effect of five different supplementary feeds on growth, survival and production were investigated for juveniles of Macrobrachium rosenbergii. The best growth was obtained with the feed containing 31.50% dietary protein. Feed conversion ratio decreased with increasing weight of prawn and is negatively correlated with dietary protein level. The highest average weight gain (48.03g) of prawn was found in treatment T1. The mean survival rates were found at 86.46, 81.33, 75.33, and 79.44 and 78.33% in T1, T2, T3, T4 and T5 treatments, respectively. The comparable net production of freshwater prawn was (166.14kg/bigha) significantly higher (P≤0.05) in treatment T1 among all the treatments. The feed conversion ratio was the lowest (1.13) and specific growth rate was the highest (2.19%) found in treatment T1.Considering all facts, the better growth performance was recorded in treatment T1 compared to other treatments T2, T3, T4 and T5.

Location: Sadar Upzilla, under Bagerhat district

Start Date: 00-08-2014

End Date: 00-12-2014

Program Area: Animal Health and Management

Commodity: Prawn, Feed

Objectives:

The proteins are primarily necessary for growth and defense while, fats and carbohydrates provide energy. All these nutrients are interrelated and have to be the part of diets to be fully utilized by the body. 36-40% of given diets for M. rosenbergii was found to be lost in the water and not ingested. Since, feed composition protein, lipid, carbohydrate etc. largely influences the growth of prawn; the determination of optimal feed is needed for maximization of its culture production as well as to ensure the sustainable higher growth rate, survival and breeding efficiency (Teshima and Kanazawa, 1987). In this regard, the present study was designed to work out the effect of different supplementary diets (Artificial) on the growth perspectives of M. rosenbergii.

Methodology:

This research work was conducted in five treatments with three replications for each to study the effect of different supplementary feeds on growth, survival and production of M. rosenbergii.

2.1. Study area and duration A 150-days experiment was conducted during August to December 2014 at Sadar Upzilla, under Bagerhat district (22.6633° N, 89.7917° E).

2.2. Experimental Design To study the growth performance and production of Macrobrachium rosenbergii, five treatments were selected in the present experiment, each with three replications. The treatments were market available prawn feed Quality Gold (T1), Quality Special (T2), Soudi-Bangla (T3), One Feed (T4) and Jamuna Feed (T5).

2.5.2. Water quality monitoring Throughout the experimental period, the water quality parameters were recorded monthly. Transparency (cm), temperature (?C), pH, Dissolved oxygen (mg/l), Alkalinity (mg/l), Hardness (mg/l) were measured monthly. Temperature and transparency were measured on the spot. The analyses of other water quality parameters were done in the Fisheries and Marine Bioscience Lab at Jessore University of Science and Technology and sometimes measured in the field manually. 2.5.3. Growth measurement The growth of prawn was monitored monthly. The sampling was done with the help of a cast net for the determination of their total body weight and length. Experimental data collected during the growth trial were used to determine the growth parameters as follows:

i) Weight gain (g): Weight gain = Mean final weight − Mean initial weight

ii) Percent weight gain (%): % Weight gain= (Mean final prawn weight-Mean initial prawn weight) / (Mean initial weight) x 100.

iii) Specific growth rate (% per day):

2.5.4. Statistical analysis For the statistical analysis of the data, one-way ANOVA (Analysis of Variance) was used to determine the effect of different feeds on the growth of prawn. Data analysis was done by using the SPSS software (Statistical Package for Social Science) version-20 according to Post-Hoc Tukey Kramer Test to identify the significance level of variance among the different treatment means.

Achievement/Findings:

The investigation focused on the effect of different supplementary feed on the growth performance of prawn. The water quality parameters of the experimental ponds were studied. There was no adverse condition during the study period. Results indicated that treatment T1 was superior to other feeds with regards to the growth rate, FCR, SGR, survival rate and production. Treatment T1 containing crude protein of (31.50%), lipid of (6.79%), ash of (4.91%) and moisture of (8.98%) are recommended as a suitable supplementary feed for suitable growth of freshwater prawn M. rosenbergii.
