PENGARUH PERBEDAAN JENIS PAKAN ALAMI JENTIK NYAMUK, CACING SUTRA (Tubifex sp), dan KUTU AIR (Daphnia sp). TERHADAP PERTUMBUHAN IKAN CUPANG (Betta splendens) DI BAK PEMELIHARAAN


Abstract
Betta fish is a type of freshwater ornamental fish that has many unique characteristics. The aim of this research was to determine the type of natural feeding that had the best effect on the absolute weight growth of Betta fish (Betta splendes) aged 1 month. The experimental design used in this research was a Completely Randomized Design (CRD) with three treatments and nine replications. The treatments in this research were the provision of various types of natural food, treatment A (Mosquito Larvae), treatment B (Silk Worms) and treatment C (Water Fleas). The three types of natural food are given to Betta fish (Betta splendes) at the same dose of 15% of their body weight. The variable measured was the absolute weight growth of Betta fish (Betta splendes) aged 1 month. The results of the study showed that treatment B with the provision of natural silk worms (Tubifex Sp) resulted in the highest absolute weight growth of 1 month old Betta fish (Betta splendes) of 2.13 gr/head. Meanwhile, treatments A and C experienced a decrease of 1.63 gr/head and 1.41 gr/head respectively. Water quality parameters include acidity between 7.3 - 7.8, water temperature between 27.2°C - 27.9°C, and dissolved oxygen between 5.2 - 5.7 ppm.
