Amino Acid Composition in Edible Wallago Attu Muscles Represents a Significant Variation with Changes in Habitats in Different Seasons from the Godavari River Basin, India

This study aimed to investigate the total amino acid composition in the body muscles of Wallago attu in relation to the habitat difference from the Godavari River basin, India. The total amino acid content was found 11.02±1.07 to 19.80±1.70 mg/g and 10.95±1.01 to 20.57±1.31 mg/g in the body muscles of Wallago attu collected from all selected habitats in different seasons during Feb. 2010 - Jan. 2011 and Feb. 2011 - Jan. 2012. The total amino acid content in the body muscles of Wallago attu collected in the summer season from Masoli Reservoir was higher, but the total amino acid content in body muscles of Wallago attu collected from Siddheshwar Reservoir in the winter season was lower. The present study revealed that there exists a significant variation (p<0.05) in the total amino acid (mg/g) content in the Wallago attu’s body muscles, which was collected from all four selected habitats during distinct seasons. Therefore,  Fish consumers may need to decide the purchase of these common food fish species from fish markets according to their need for amino acids.
