The addition of KPDW in artificial feed is expected to increase the nutrition of the feed so that it can increase the growth of saline tilapia in ponds. The aim of this research was to analyze the effect of adding KPDW to artificial feed on the growth and survival rate of saline tilapia. Saline tilapia was reared in the West Petta Village Pond, Petta District, Sangihe Islands Regency. This research used a completely randomized design method consisting of 4 treatments, each with 3 replications, namely control, the addition of 1%, 2%, and 3% KPDW. The results obtained from this research were that the addition of 1% KPDW to artificial feed provided better absolute weight and absolute length of saline tilapia compared to adding KPDW at other doses, meanwhile, the survival value of saline tilapia in all treatments was 100%. In conclusion, the addition of KPDW to artificial feed had no significant effect on the growth and survival of saline tilapia.</p> <p><strong><em>Keywords</em></strong>: aquaculture, protein source, alternative feed</p> Numisye Iske Mose Jetti Saselah Copyright (c) 2024 Numisye Iske Mose, Jetti Saselah https://creativecommons.org/licenses/by/4.0 2024-02-28 2024-02-28 12 1 1 8 10.35800/bdp.v12i1.54397 https://ejournal.unsrat.ac.id/v3/index.php/bdp/article/view/53959 <p>This research aimed to determine the growth of snakehead fries t reared in aquaponic media and fed commercial fish food. The treatments consisted of treatment A with a protein content of 40%, B with a protein content of 35%, and C with a protein content of 30%, each with three replications. The research was conducted for 32 days. The research found the absolute growth of treatment a was 1.34 g, treatment b was 0.775 g, and treatment C was 0.605 g. The daily growth rate for treatment a was 4.18%, treatment b 2.42%, and treatment C 1.89%. Linear regression analysis between protein content in food and growth weight of snakehead fish fry had a strong relationship to both absolute growth and specific growth rate. The higher the protein content, the higher the weight growth of snakehead fry.</p> <p><strong><em>Keywords</em></strong>: snakehead fish, aquaponic, commercial food, protein</p> Eukharistian Niti Joppy D.
