Abstract/ Executive Summary:

The comparative growth performance study of Thai Sharpunti (Puntius gonionotus ) was conducted from 20th March to 18th May, 2012 by using duck weed ( Lemna minor ) and Azolla fern ( Azolla pinneta) as in earthen pond of the Department of Aquaculture, Bangladesh Agricultural University, Mymensingh. Duck weed and Azolla fern were supplied as dietary feed in two separate treatments and each with three replications. Fifteen fingerlings of Thai sharputi was stocked in each pond. Average size and weight of Thai sarputi were 5.75 cm and 21g in T₁ and 5.50 cm and 20g in T₂, respectively. The ranges of physico-chemical parameters viz, water temperature (25.00 to 33.50⁰C), air temperature (31.00 to 34.50⁰C), transparency (28 to 34 cm),dissolved oxygen (6.00 to 7.20 mg/l), free CO₂ (2.00 to 3.33 mg/l), pH (6.9 to 7.45), total alkalinity (48 to 61 mg/l), phosphate-phosphorus (1.40 to 2.50 mg/l) and nitrate-nitrogen (2.13 to 3.20 mg/l) were within the productive range. Initial body weight, final body weight, weight gain, survival rate, specific growth rate(SGR), food convertion ratio (FCR), percent weight gain, average daily gain (ADG) were observed as 21 and 20g, 356g and 308g, 335 and 288g, 90 and 85%, 558and 480% per day, 5.28 and 6.10, 1595 and 1440%, 5.58 and 4.80g in both the treatments,respectively. Calculated gross and net fish production in T₁ with duck weed were 2.40 and 2.08 ton/ha/yr and in T₂ with Azolla fern were 2.26 and 1. 94 ton/ha/yr, respectively. It was found that the net fish production in T₁ was 1.32 times higher than T₂ (P≤ 0.01, 0.05). The present study showed influence of duck weed as dietary feed on the production of Thai Sharpunti (P. gonionotus) was positively significant. So it might be concluded that duckweed had better effect as dietary feed than Azolla fern on monoculture of Thai sharpunti.

Keywords: Thai Sharpunti, Duck weed, Azolla fern, Growth performances

Location: Department of Aquaculture, Bangladesh Agricultural University, Mymensingh,

Start Date: 20-03-2012

End Date: 18-05-2012

Program Area: Animal Health and Management

Commodity: Fish

Objectives:

To study the comparative proximate composition energy distribution of duck weed and Azolla fern.

Methodology:

A series of six ponds of Department of Aquaculture, Bangladesh Agricultural University, Mymensingh, were selected to conduct the research work from 20^th March to 18^th May, 2012. The ponds are rectangular in shape. The size, depth, basin conformation of all the six ponds are more or less similar. The ponds are free from aquatic vegetation and well-exposed to sunlight. The surface area of each of the ponds is about 26 m 2 with an average water depth of 1.0meter. The ponds were completely dependent on water supply from a deep tube-well. The pond’s wall is well protected and covered with fine net. Fifteen fingerlings of Thai sharpunti (P gonionotus) were stocked in each the pond. The average length and weight of sharpunti were 5.50 cm, and 21 g. After collection the fresh weeds were weighed and then supplied to the fish culture ponds under treatment^{- 1} and treatment-2 at the rate of 60% of total body weight of all the fish of the ponds. The physical parameters such as temperature ( °C) and transparency (cm) and chemical water quality parameters such as dissolved oxygen (mg/l), pH, free carbondioxide (mg/l), total alkalinity (mg/l), phosphate phosphorus (PO₄ -P) (mg/l), nitrate nitrogen (NO₃ -N) (mg/l) were done by water quality parameters test kits.

Achievement/Findings:

The present study showed higher growth performance in treatment-1 followed by treatment-2.The net fish production was 1.32 times higher than T₂ . FCR value in T₁ was significantly lower than T₂. F-test of gross and net productions showed (P ≤ 0.01, 0.05) significantly higher production in T₁ than T₂ i.e. influence of duck weed as dietary feed on the production of Thai Sharpunti (P. gonionotus) was positively significant. So it might be concluded that duckweed had better effect as dietary feed than Azolla fern on monoculture of Thai sharpunti.
