abstract
To test the effect of different stocking density on their growth and survival rate of common carp, Cyprinus carpio Linnaeus 1758 was cultured in three tanks for ten weeks from September 2016 to January 2017. These carps were fed with commercial small pellets (Tokyu) every day. A total of 90 healthy looking fingerlings were selected and used. Mortality and survival rates in each tank were checked every day. During the studied period, the survival rate was the highest in GI (100%) followed by GII (93.33%) and GIII (91.11%) respectively. The result in this project shows that GI is the best population density for the growth and survival rates of common carp. GI (5 density) could be expressed as optimal density. Therefore, stocking rate of 0.13 fish/L would be suggested as optimal rate.
