Abstract

ABSTRACTThe purpose of this research to know the calsium content effisiencyoptimal utilization for growth Taiwanase clam (Anodonta woodiana) was carriedout in laboratory. Twenty clams with a size of 5-6 cm and a weight of 15-16grams, were reared in plastic container of 100x50x50 cm in size, contain 300 litersof fresshwater. Taiwanase clam was cultivated for 60 days with the application 4treatments and 3 replications the control without the addition of caslcium (0 ppm),the addition calcium (CaCO3) into the media as much 25 ppm, 50 ppm, 75 ppm.The result of research indicate additional calcium (CaCO3) as much 25 ppm toinside the media of cultivated consequence effeciency exploit calcium going upand fast growth the quality rate daily clam also more up. That’s also, the influencealso to the condition quality of water specialy kesadahan (alkalinitas). Asconclusion, the addition of calcium at 25 ppm into the cultivation mediumresulted efficiency calcium Taiwanase clam utilization with the value (6,22 %perday), the calcium with concentration 25 ppm in culture media constitutecalsium a which optimal and the best growth (1,10% per day).Keywords :Aquaculture; Calsium; Effisiency; growth; Taiwanase clam.

Abstract

Cyprinus carpio has a particular optimum temperature for its appetite.Marine temperature increase and oxygen needs of organism is according to Van’tHoff law that every chemistry change, its reaction rapidity increase by twice tothird times every temperature increase of 10 °C.Treatment tested is in temperature of 26OC; 28OC; 30OC and 32OC.Parameter observed is fish relative weight growth, length increase and survivalrate.Research yield indicating that the relative weight growth (%) and larvaelength increase of highest gold fish (Cyprinus carpio) is that on temperature of28 OC) and according to equals Y = -56.597x2 + 3204x - 41537 it is known thatthe optimum temperature for larvae supervising of Cyprinus carpio is intemperature of 28.305OC.
