DISTRIBUTION OF COLLAGEN IN THE MUSCLE-TISSUE OF COMMERCIALLY IMPORTANT TROPICAL FISHES

Stroma proteins refer to slightly soluble/insoluble proteins obtained after removing water and salt soluble proteins in the muscle. The main constituent of stroma protein is collagen. The collagen contents of a few species of Indian fishes were determined. In the present study, a n attempt was made to classify twenty species of commercially importan t fishes based on the percentage of total collagen on total proteins i nto three categories - low, medium and high collagen content species. Elasmobranchs were found to have a high content of collagen compared t o teleosts.
