- This study aims to determine the method of generating water flow inside a round container to increase the survival and growth of common carp fingerlings. The approach used in this research is an experimental method which applies a Completely Randomized Design (CRD) and consists of three and five replications. The treatments used are (A) No Water flow (control), (B) 0.1 m/s of water flow, (C) Water flow utilizing an additional venturi system. The test fish used were 450 majalaya common carp of size 3-5 cm. The containers used in this research are in the form of 15 gallons capacity with a diameter of 27 cm x 36 cm height x bottom diameter of 6 cm containing 19 liters of water. The density of common carp during the study was 30 carp per treatment container. The treatment period is 40 days. The food given is 5% of the bodyweight of fish. Water quality parameters (temperature, pH, dissolved oxygen, ammonia and nitrates) were observed every 10 days for 40 days. Other parameters are survival, daily growth rate, feed conversion ratio, and feed efficiency observed every 10 days for 40 days. The results showed that the use of water flows with the venturi system provides the best results - with a life growth rate of 1.5%, a feed conversion ratio of 3.18, feed efficiency of 31.73% and 75% survival.
