Abstract

This study aims to evaluate the effect of the addition of growth hormone (rGH) and spirulina flour on the performance of absolute weight growth, survival, feed efficiency, and feed conversion ratio (FCR) of cupang fish (Betta spp.). This study used a completely randomized design (CRD) with four treatments with three replications, i.e., A) Dose of growth hormone 1.5 mg+3 g spirulina flour; B) Dose of growth hormone 2 mg+3g spirulina flour; C) Dose of growth hormone 2.5+3 g spirulina flour; D) Control (no treatment). The results showed that the addition of growth hormone (rGH) and spirulina to commercial feed affected absolute weight growth of 2.27 ± 0.90 g. The survival rate was 75.00±1.11 %, the feed efficiency value was 28.98±1.17 %, and the feed conversion ratio was 1.11±0.022. The highest color intensity was found in treatment C with a score of 6.

Abstract

Comet fish (Carasius auratus) is one type of ornamental fish that is very popular with consumers and has commercial value because it has various shapes and colors such as yellow, white, black and red. Efforts to obtain the percentage of females can be done by sex transfer by immersing the larvae in purwoceng extract. Purwoceng extract (pimpinella alpina) is an aphrodisiac plant that contains compounds related to phytosteroids, such as stigmasterol which functions to improve sexual quality. This study used a completely randomized design with 4 treatments and 3 replications, the dose used was treatment A without dose (control), B dose 10 mg/l, C dose 15 mg/l, D dose 25 mg/l. The results showed that the highest percentage of female fish was present in the treatment dose (B) 10 mg of purwoceng extract, which was 45.94%, followed by treatment A 42.39%, treatment C 24.36%, treatment D 10.83%. While the highest growth was found in treatment D, namely 1.115 g, followed by C 0.820 g, B, 0.910 and A 0.785.
