Abstract: | Mass mortality in pearl oyster farming by virus infection has become a serious problem. This occurs due to food shortages in the summer. An experiment was conducted on the hypothesis that with artificial feeding, the mass mortality could be decreased. A low cost semi-continuous culture system, outdoors for Chaetoceros gracilis is required. The object of such a system would be to achieve a supply of 600l culture solution in chlorophyll a of 600μg/l per day using four 500l tanks. In a continuous culture system, the cost of addition of nutrients is high so. A simple semi-continuous system was utilized using algae propagation water soluble glass to release trace minerals and nutrients (e.g. silicate, phosphorus, iron) along with nitrogenous fertilizer. It proved possible to control the rate and amount of dissolution. As a result of cultivating with this system during the summer, chlorophyll a, 550 to 850μg/l and 290 to 370 million cells/ml were produced on average. Cultivation of C. gracilis outdoors was achieved in high concentration. |
