SEASONAL CHANGES IN BIOCHEMICAL COMPOSITION IN THE MUSCLES OF FRESH WATER FISH Channa marulius

The present investigation deals with study of seasonal biochemical variation in muscles of indigenous fresh water fish Channa marulius commonly known as maral in local language. Seasonal variations in muscle moisture, protein, glycogen and lipid is studied during December 2020 to November 2021.Moisture content in the Muscles of C. marulius is minimum in the month June (77.80%) and maximum moisture content in the month January (79.51%) with average mean value 78.52%. Protein content in the Muscles of C. marulius on dry weight basis is minimum in the month October (70.5053±0.163299%) and maximum Protein content in the month of May (79.63863 ± 0.20548%) with average mean value 75.08585 ± 0.259712%.Glycogen content in the Muscles of C. marulius on dry weight basis is minimum in the August (0.558998 ± 0.020548%) and maximum Glycogen content in the month January (1.948998 ± 0.020548%) with average mean value 0.95122 ± 0.021229%. Lipid content in the Muscles of C. marulius on dry weight basis is minimum in the February (1.725665 ± 0.044969%) and maximum Lipid content in the month of November (9.165665 ± 0.020548%) with average mean value 5.722054 ± 0.023625%. The present study may give insights in to develop the policies for conservation of C. marulius. Also, the outcomes may be useful in identification of ideal season for capture of this fish.
