Collagen was isolated and characterized from the skin of brown backed toadfish (Lagocephalus gloveri), processing wastes. The
total collagen yield extracted was 54.3% on the basis of lyophilized dry weight compared to other vertebrates. According to the electrophoretic
pattern, the skin collagen of the fish consisted of heterotrimer a1a2a3. Moreover, the denaturation temperature was
28 C, which was about 9 C lower than that of collagen from porcine skin. Therefore, there is a possibility to use brown backed
toadfish skin collagen as an alternative source of collagen for industrial purposes and subsequently it may maximize the economical
value of the fish.
