Abstract: Copepod cultivation is influenced by phytoplankton as natural food organism. The aim of the research is to know the copepod density fed on Chlorella sp. and Tetraselmis chuii cultivated in different volume media. The research was conducted from May to October 2005 at the Laboratory of Biological Oceanography, Diponegoro University. Copepods were collected monthly from Demak waters. The copepod cultivations were done in 2 I bekers and 20 I aquariums. A total WO ind./L of copepod in 2 L media and 1000 ind. /L of copepod in 201 media were used as test biota per period of cultivation. The Chlorella sp. of 15.200 cell / ml and Tetraselmis chuii of 11.000 cell / ml taken from Balai Besar Pengembangan Budidaya Air Payau (BBPBAP) jepara were fed to copepod. The copepod density was weekly observed for 3 weeks cultivation. The observations were replied monthly for six month. The water quality such as temperature, salinity and pH were observed daily. The copepod density showed 227 303 ind. / L in 2 I media and 25343808 ind./L in 20 I media fed on Tetraselmis chuii. While the copepod density were 297377 ind. / L cultivated in 2 L media, and 32414824 ind. / L for 20 L media fed on Chlorella sp. The two species of phytoplankton gave the same growth model for the copepod. The increase of copepod density fed on Chlorella sp. was higher than the one of Tetraselmis chuii.
