This study was conducted to investigate the effect of carotenoid source and dosages on plasma cortisol and glucose of Lake Kurumoi rainbowfish due to transport stress. The juvenile fish (weight 1.84 ± 0.03g, total length: 5.2 ± 0.09 cm [mean ± SE]) were fed different carotenoid synthetics such as astaxanthin (AS), canthaxanthin (CS), lutein (LS) at different dosages (130 and 260 mg kg-1) for two months included basal diet (without carotenoids) which was considered as control. After feed treatment was performed, simulation of transport stress was conducted for 15 hours. Plasma cortisol and glucose concentration of blood were measured during transport stress at 0 hour before transport (H0-); and at 0 (H0+), 24 (H24), 48 hours (H48) and 72 hours (H72) after transport. Fishes were fasted during measurement periods. The present study indicates that there are different variation of plasma cortisol and glucose on different carotenoids source and dosages in Lake Kurumoi rainbowfish. Fish fed with carotenoid source at different dosages provided different pattern from each other. The increase of plasma cortisol on basal fish diet was the fastest one, that was directly at 0 hour after transport (increased by 186%) compared to fish fed carotenoid that was slower and slightly increased at 24 hours after stress. It was contrary to the plasma glucose. Fish fed carotenoid diets tended to suppress stress than basal diet (without carotenoid).Pages: 272-277 | 325 Views 15 DownloadsDownload Full Article:
