Abstract:
Oligochitosan (COS) was prepared by gamma Co-60 irradiation of chitosan/H2O2 solutions and mixed with cornstarch to form the powder with content of 100 000 mg COS/kg. The striped catfish (P. hypophthalmus) was fed with diets containing 100 mg COS/kg feed for 9 months at pond culture. The effects of COS supplementation on growth performance, feed conversion ratio (FCR) and survival rate in striped catfish were investigated. The results indicated that the growth performance and survival rate of striped catfish fed with 100 mg COS/kg were significantly improved and the FCR decreased. The average weight gain, survival rate and FCR of striped catfish fed with diets containing COS were 971 ± 85 gram, 83.19 ± 0.35 % and 1.477 ± 0.013 in comparison with 896 ± 78 gram, 78.43 ± 0.64 % and 1.578 ± 0.038 of control group, respectively. Thus, COS can be potentially utilized as immunostimulants and growth promoter for aquaculture.
