Biochemical composition and gross energy value of garua bachcha, clupisoma garua from a coastal river, bangladesh

Abstract

Clupisoma garua is a catfish species of the order Siluriformes locally known as Ghaura/Gharua which is native to Bangladesh, Pakistan, India, Myanmar, and Nepal. This study was carried out from January 2019 to September 2019 at three months interval to estimate the proximate composition and energetic value of C. garua from the Payra River through AOAC standard method. Significant differences were observed in case of proximate composition (P < 0.05) for moisture (74.77-75.46%), ash (2.11-2.44%), crude protein (18.69-19.09%) and lipid (2.74-2.84%) contents. Moreover, the energy contents of these samples were calculated from the proximate analysis using accepted conversion factors. The energy contents range from 76.40-77.57 Kcal in this study. This energy content and valuable information on the rich nutrient composition of C. garua should guide policy and programs to improve food and nutrition security, as well as these values, are useful references for consumers to choose fish and based on their nutritional contents in Bangladesh.
