Ascertaining the seasonal variations in nutritional value of Channa striatus from Halali reservoir of Raisen district (Madhya pradesh, India)

Abstract

Determining the seasonal alterations in the essential nutritional constituents of Channa striatus fish will be important to estimate their nutritive value with different seasons so as to plan the most beneficial consumption time period, commercial processing and storage for future. In the present work, it was evaluated that the seasonal variations in nutritional value of Channa striatus including total carbohydrate, protein and lipid content with respect to three season’s i.e winter, pre-monsoon and post monsoon from Halali Reservoir in the Raisen district, of Madhya Pradesh. Nutritional components like carbohydrate, protein and lipids are severely influenced with the change in season and water quality parameters. Total carbohydrate, protein and lipid were estimated by phenol-sulphuric acid method, Follin’s-Lowry method and Folch et al. method respectively. The nutritional analysis showed that the nutritional value of Channa striatus in the winter sample (January to February) was maximum as compared to post monsoon (October to November) and pre-monsoon (Juneto July) sample. So, it is suggested that the consumption of Channa striatus fish of Halali reservoir in the winter season must be increased for obtaining maximum nutritional benefits
