Nutritional Quality Components of Indigenous Freshwater Fish Species, Puntius Stigma in Bangladesh

A. S. M. Musa
Department of Zoology, Naogaon Govt. College, Naogaon, Bangladesh.

Abstract/ Executive Summary:

Proximate biochemical compositions of body muscles of Puntius stigma (male and female) such as moisture, protein, lipid, ash and carbohydrate were determined in freshly caught fishes. Some mineral compositions, such as phosphorous, potassium, magnesium, calcium, zinc, copper, manganese and iron were also evaluated. Some amino acids were also detected during analysis. The moisture content 75.60% was found to be higher in female, while protein 21.50%, fat 2.70%, ash 1.90% and carbohydrate contents of 1.55% were higher in male. In protein analysis of two fishes (male and female), most of the minerals were found in higher in male. But manganese and iron were lower in male. Essential amino acids were also estimated. Nutritional values were higher in males than in females. Overall, the fish has a high nutritional value in terms of protein, fat, vitamin and minerals, which are not common in other foods in Bangladesh.

Keywords: Puntius stigma, Nutritional value, Freshwater fish species.

Start Date: 00-01-2005

End Date: 00-12-2006

Program Area: Quality and Nutrition

Commodity: Fish

Objectives:

The present study, describes the nutritive value and food quality of Puntius stigma.

Methodology:

Fresh samples of Puntius stigma were collected from January, 2005 to December, 2006 from Shaheb bazaar fish market of Rajshahi. Determination of moisture content was done following the conventional procedure and lipid was determined by the method of Bligh and Dyer (1959). Carbohydrate was estimated by Authrone method, ash content was determined following the method of Jayaraman (1985), protein content was determined by the micro Kjeldahl method. In the present study, mineral analysis was made from the samples taken from the whole fish. Macro and micro nutrient compositions of fresh fish samples were determined using Perkin-Elmer 2380 Atomic Absorption Spectrophotometer following modified method of Cresser and Parson (1979). Amino acid analysis was done following the methods of Bidlingmeyer et al. (1994) using column from waters corporation (catalogue # 10950).

Achievement/Findings:

The essential amino acid spectrum is an index of biological value of the fish protein. Both male and female fishes are important nutritionally because of their relatively higher amount of fat and protein contents.
