Kan tawes (barbonymu sgonionotus) merupakan salah satu ikan air tawar yang banyak dibudidayakan karena memiliki beberapa keunggulan, diantaranya yaitu mudah dibudidayakan, memiliki nilai jual, sumber protein hewani dan banyak disukai oleh masyarakat untuk dikonsumsi. penelitian ini bertujuan untuk mengetahui pengaruh pemberian daphnia sp yang di perkaya dengan bunga rosella terhadap pertumbuhan larva ikan tawes (barbonymus gonionotus). penelitian ini dilakukan pada bulan oktober - november 2023, bertempat di laboratorium pembenihan dan pembiakan ikan fakultas kelautan dan perikanan universitas syiah kuala, banda aceh. metode penelitian dengan cara rancangan acak lengkap (ral) dengan 4 kali perlakuan dan 5 kali ulangan yaitu dengan pengayaan daphnia sp. dengan bunga rosella perlakuan a (0 gr ), b (1 gr), c (1,5 gr), d (2 gr). hasil yang didaptkan bahwa pemberian daphnia sp. yang sudah diperkaya dengan tepung bunga rosella berpengaruh nyata terhadap pertumbuhan panjang mutlak, berat mutlak serta terhadap kelangsungan hidup larva ikan tawes air tawar (barbonymus gonionotus), perlakuan terbaik pada penelitian ini diperoleh pada pengkayaan daphnia sp. dengan tepung bunga rosella sebanyak 2 gram. kata kunci : ikan tawes, dhapnia sp. , bunga rosella

Tawes fish (Borbonymus gonionotus) is one of the freshwater fish that is widely cultivated because it has several advantages, including being easy to cultivate, having sales value, being a source of animal protein and being widely liked by people for consumption. This research aims to determine the effect of giving Daphnia sp enriched with Rosella flowers on the growth of Tawes fish larvae (Barbonymus gonionotus). This research was conducted in October - November 2023, at the Fish Hatchery and Breeding Laboratory, Faculty of Marine Affairs and Fisheries, Syiah Kuala University, Banda Aceh. The research method was a Completely Randomized Design (CRD) with 4 treatments and 5 replications, namely by enrichment of Daphnia sp. With Rosella flowers treatment A (0 gr), B (1 gr), C (1.5 gr), D (2 gr). The results obtained were that giving Daphnia sp. which had been enriched with rosella flower flour had a significant effect on the growth of absolute length, absolute weight and the survival of freshwater tawes fish larvae (Barbonymus gonionotus). The best treatment in this study was obtained by enriching Daphnia sp. with 2 grams of rosella flower flour. Kata kunci : :silver barb Dhapnia sp. , rosella flower
