PENGARUH PENAMBAHAN KALSIUM PADA MEDIA BUDIDAYA TERHADAP BEBAN OSMOTIK DAN KAITANNYA DENGAN PERTUMBUHAN KIJING TAIWAN (Anodonta woodiana LEA)
ABSTRACT: A research to know
the effect of calcium suplementation in culture medium on osmatic gradient and
its relation to growth of Taiwanese Clam was carried out in laboratory. Twenty
clams (4-5 cm and 1-15 grams in size) were reared in plastic container of
100x50x50 cm in size, contain 250 liters of freshwater. The level of calcium
supplementation applied in this experiment were 0 ppm, 25 ppm, 50 ppm and 75
ppm and each treatment had three replications. Result of the experiment show
that calcium suplementation of 25 ppm on clam culture medium (17,63 CaCO3 in
medium) gave the lowest level of gradient osmatic (0,013 m Osm/kg H2O) and the
best growth (1,10 % per day).
