Evaluation of Caulerpa lentillifera as artificial feed on growth rate and survival level of carp (Cyprinus carpio)]

This study aimed to evaluate the dose and utilization of Caulerpa lentilifera seaweed as artificial feed on the growth rate and survival rate of carp. This study used a completely randomized design (CRD) with four treatment levels and three replications. The fish used was carp (Cyprinus carpio) measuring 3-5 cm with a stocking density of 10 acres/bucket for 42 days of rearing. The doses of Caulerpa lentilifera flour added to the feed were 0%, 10%, 20%, and 30%. The results showed that the addition of Caulerpa lentilifera flour had a significant effect on growth rate, survival rate, feed utilization efficiency, and carp protein efficiency ratio. Giving Caulerpa lentilifera flour with a dose of 20% in the feed was the best dose for the relative growth rate of 6.83%, survival rate of 75%, efficiency of feed utilization of 20.59% and protein efficiency ratio of 3.79%. Caulerpa lentilifera in feed is able to increase the efficiency of feed utilization so as to support the growth rate and survival rate of car
