Chaetoceros muelleri is a favorable food for the larvae of shellfishes and other marine animals.At a temperature of 25-30.5℃, light intensity 1,000-1,100 lux, and pH 7.98-8.48, experiments were carried out to find the optimum salinity, phosphate, and nitrate concentration for the growth of this small diatom.The following are the results of the present investigation:(1) The optimum salinity is 25.9‰(17-32.21‰).(2) The suitable phosphate concentration is PO4-P 19.9-139.3 μg-at/1, and the optimum concentration is 99.5 μg-at/1.(3) The suitable nitrate concentration is NO3-N 1,976-7,904 μg-at/1, and the optimum concentration is 5,928 μg-at/1.
