Abstract

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. Keywords: snakehead fish, aquaponic, commercial food, protein

Abstract

The brightness and high color saturation determine the selling price of ornamental goldfish. Color saturation is the color intensity visible to the naked eye from the appearance of goldfish. Caulerpa racemosa seaweed contains β-carotene, a type of carotenoid that is a red, yellow, and orange pigment. The research aimed to determine the effectiveness of adding C. racemosa flour to artificial goldfish (Carrasius auratus) feed. The experimental design used was three treatments of adding C. racemosa flour to artificial feed, namely 0%, 1%, and 1.5%. The experiment was carried out for 45 days with intensive fish care in an aquarium. Observation of color intensity using M-TCF (toca color finder) at the beginning and end of the study by three panelists. The results showed that increasing the color saturation of goldfish with the addition of 1.5% C. recomosa seaweed flour gave the best results.

Saturasi warna merupakan intensitas warna yang secara kasat mata tampak dari performans ikan mas koki. Rumput laut Caulerpa racemosa mengandung β-karoten yaitu jenis karotenoid yang merupakan zat pigmen warna merah, kuning dan jingga. Tujuan penelitian untuk mengetahui efektifiktas tepung C. racemosa yang ditambahkan pada pakan artifisial untuk ikan mas koki (Carrasius auratus). Rancangan percobaan yaitu 3 perlakuan penambahan tepung C. racemosa pada pakan artifisial: 0%, 1%, dan 1,5%. Percobaan dilakukan selama 45 hari dengan perawatan ikan secara intensif dalam akuarium. Pengamatan intensitas warna menggunakan M-TCF (toca color finder) pada warna awal dan warna akhir penelitian oleh 3 panelis. Hasil penelitian menunjukkan bahwa peningkatan saturasi warna ikan mas koki dengan penambahan tepung rumput laut C. recomosa sebanyak 1,5% memberikan hasil terbaik. Kata kunci: Caulerpa racemosa; Carrasius auratus; pakan artifisial; karotenoid; M-TCF.
