The freshwater catfish Rita rita (Hamilton, 1822) (Family: Bagridae) inhabits the tropical rivers and estuaries contributes to capture fisheries production in Indian subcontinent. It enjoys high consumer preference as a valuable food fish due its muscle texture, good taste lesser intramuscular spines; however, basic nutritional information on species is not available. In present study, we report proximate composition, amino acid, fatty acid mineral composition of different size groups R. rita. Proximate analysis showed that rich protein low fat. content (19.55%) was found be highest medium fishes. Leucine, phenylalanine glutamic are predominant acids all leucine (18.67 g 100 g-1 protein) (10.55 contents were significantly macro-minerals potassium (13800 ppm) phosphorous (14100 group, whereas calcium (1900 large group. micro-minerals iron zinc higher amount important source protein, essential (leucine, phenylalanine, acid) micro elements (Zn, Fe). Comparative evaluation (weighing 500-800 g) nutritionally superior other groups.
