To use collagen from freshwater fish skin as an alternative source of mammalian collagens for biomedical applications, we tested the rheological and structural properties of collagen from the skin of largefin long-barbel catfish (Mystus macropterus) by dynamic viscoelastic measurements. Fish skin collagen solution (FSCS) exhibited a shear-thinning flow behavior. The complex viscosity (), loss tangent (tan ) and relaxation time of 1.5% FSCS decreased with the increase of temperature. Also, tan decreased while the relaxation time increased with the increase of FSCS concentration. FSCS had considerably lower storage modulus (G'), loss modulus (G"), values and relaxation time and a higher tan value than those of bovine skin collagen solution (BSCS). However, FSCS behaved without regularity above , which was in agreement with the result that the dynamic denaturation temperature of this collagen was approximately . These results indicated that temperature and concentration could be tools suitable for adjusting FSCS viscosity. The Arrhenius-type time-temperature superposition (TTS) was applied. In addition, the activation energy of for 1.5% FSCS was calculated according to the Arrhenius equation, indicating a weaker entanglement effect amongst fish skin collagen molecules than that amongst bovine skin collagen molecules, which was in agreement with the results from AFM measurement.
