Abstract/ Executive Summary:

Proximate biochemical compositions of Mystus bleekeri (Day), such as moisture, protein, lipid and carbohydrate were determined in freshly caught fishes. Studies were also made on the changes in proximate composition in ice preserved condition of the fishes. Some mineral compositions, such as phosphorous, potassium, magnesium, calcium, zinc, copper, manganese and iron were evaluated. The fish comprised of 72.94% moisture, 16.67% protein, 6.12% lipid, 2.53% ash and 1.63% carbohydrate in fresh condition, and 75.92%, 14.16%, 5.07%, 2.85% and 1.91% of the above components, respectively in 10 days ice stored condition. The mineral compositions were 835 mg potassium, 120 mg magnesium, 180 mg calcium, 16 mg zinc, 5.71 mg copper, 6.12 mg manganese and 23.5 mg iron per 100 g of M. bleekeri. Key words:

Keywords: Mystus bleekeri, Biochemical composition, Nutritional value.

Location: Padma River, Rajshahi, Bangladesh

Start Date: 00-04-2002

End Date: 00-03-2003

Program Area: Quality and Nutrition

Commodity: Fish

Objectives:

To identify the nutritive value and food quality of fresh, dried and ice preserved Mystus bleekeri.

Methodology:

The live samples of M. bleekeri collected from the river Padma near Rajshahi from April 2002 to March 2003 were killed and preserved in ice. The moisture content of the fish was determined following the conventional procedure, lipid was determined, carbohydrate was estimated by Authrone method, ash content was determined following the method of Jayaraman (1985) and protein content was determined by the micro Kjeldahi method. Mineral analysis was made from the samples taken from the whole fish. For the macro and micro nutrient contents of the fresh, ice preserved and sun-dried fish samples, composition was determined by using Perkin-Elmer 2380 Atomic Absorption Spectrophotometer following the modified method of Cresser and Parson.

Achievement/Findings:

Studies conducted on the changes in proximate composition in 10 days’ ice preserved condition. After 10 days’ storage, moisture content was 75.92%. This value is slightly higher than that of the freshly caught fish. The higher moisture content of the ice stored fish was probably associated with the uptake of water during ice storage. The protein was 14.16%. For correct evaluation and better comparison, the data for protein, total lipid and ash contents have been recalculated on moisture free basis and shown in parenthesis. Crude protein value on moisture free basis was 58.54%. The result indicated the loss of crude protein in fish sub sarcoplasmic protein. The alteration of protein was probably linked with the increase of water holding capacity of the fish muscle during ice storage. In case of magnesium and calcium the values are 120 mg/100g, 180 mg/100g respectively. However, the values obtained for potassium, magnesium and calcium were higher than those reported from other fin fish and shell fish muscles.
