Abstract
Saline tilapia (Oreochromis niloticus, L) is potential to be cultured due to its high content of nutrition. This study aims to determine the optimal dosage of Caulerpa lentillifera meal in feed for growth and survival rate of saline tilapia. This research was conducted on August to September, 2018 at Brackish Water Aquaculture Development Center, Aceh, Indonesia. The study used an experimental method with a completely randomized design (CRD) with 5 treatments of meal dosage and 4 replications, namely; A = 0 g, B = 10 g, C = 20 g, D = 30 g, and E = 40 g Caulerpa lentillifera meal Kg−1 feed. The observed parameters included absolute weight gain, absolute length growth, daily growth rate, feed effeciency and survival rate. The results showed that the addition of Caulerpa lentillifera meal in feed significantly (p <0.05)affected the growth and survival rate of saline tilapia. The optimal dosage of meal was 20 g Caulerpa lentillifera meal Kg−1 feed a(treatment C).
