Abstract

The field of fisheries study has employed many tools such as morphometric and proximate analysis to differentiate fish population and fish composition. Morphometrics could be referring as a more or less interwoven set of largely statistical procedures for analyzing variability in size and shape of organs and organisms. Morphometric differences among stocks of a species are recognizing as important for evaluating the population structure and as a basis for identifying stocks. Proximate body composition of a fish provides percentages of various body contents i.e. water, fat, ash, protein in the body. It also illustrates the health and physiological condition. Esomus danrica is an admired for food fish in a small indigenous fish species. Regression has been applyed as a statistical tool to assess the effect of body size and condition on proximate composition of E. danrica. The mean ? standard deviation of total length = 6.86 ? 0.89 with ranges = 5.30 to 8.70 and Wet body weight = 2.94 ? 1.35 with ranges = 1.38 to 6.15 were estimated in morphometric parameters. Similarly, the mean ? standard deviation of total length (cm) = 6.87 ? 0.9075992 with ranges 5.60 ? 8.70 and Body weight (g) 3.04 ? 1.3871268 with ranges = 1.68 ? 6.15 were calculated in proximate body. The relationships between %water and various body constituents in wet body weight showed ash = 3%, fat = 5%, protein= 18% and water = 73%. The relationships between various body constituents in dry body weight estimated that ash = 12%, fat = 20% and protein = 68%.It concluded that to future prospects it is very important through nutritional value because it has large amount of protein. This study has been very helpful for ichthyologists, taxonomists and nutrition experts to know the nutritional value of small size fish. Additionally, the first reference for proximate body composition for Esomus danrica has been provided.
