ResumoSummary Fish scale was decalcified and disaggregated and then collagen was prepared by limited pepsin digestion. The yields of collagens were very high on a dry weight basis; sardine 50.9%, red sea bream 37.5% and Japanese sea bass 41.0%, respectively. These scale collagens were heterotrimers with a chain composition of ( α 1) 2 α 2. Although the denaturation temperature of the collagen was lower than land animal collagen, fish scales will have potential as an important collagen source for use in various industries.
