Abstract

Red sea bream and tiger puffer larvae were fed with carotenoids (red sea bream: β-carotene or astaxanthin, tiger puffer: β-carotene) supplemented rotifers or unsupplemented control rotifer for 20 and 28 days, after hatchout, respectively. Results show that survival rates of carotenoids supplemented groups of both red sea bream and tiger puffer larvae were higher than that of each control group. The carotenoids supplemented and unsupplemented control groups exhibited a similar growth in both species during this experiment.<BR>The proliferation of splenocytes treated with 20μg/ml of Poke weed mitogen or 100μg/ml of concanavalin A (Con A) from β-carotene supplemented or astaxanthin supplemented group were higher than that of a control group in red sea bream. In tiger puffer splenocytes treated with 20μg/ml of Poke weed mitogen or 1001μg/ml of Con A from the a-carotene-supplemented group. The lymphocytes proliferated to a higher degree compared to the control.<BR>These results suggest that the supplementation of carotenoids such as a-carotene or astaxanthin to rotifers, might be of benefit in production of healthy and resistive larvae against infectious disease.
