Riyadhi et al, 2019. The Using of Water Jasmine (Echinodorus palaefolius) as Biological Filter on Angelfish (Pterophyllum scalare) Rearing.
Water quality during the research are temperaure of 25.6-27.5oC, pH of 7.2-8.3, DO of 6.2-7.1 mg/L, and NH3 of 0.01-0.30 mg/L.Key words : Goldfish, Spirulina platensis, growth, feed efficiency
The best results were obtained in treatment B with an average total length growth of 2.19 cm, average weight growth of 1.51 g, and average feed efficiency of 30.26%.
The results of research showed there was a significantly different between treatments for the growth and feed efficiency (P<0.05). The total length growth, the weight growth, feed efficiency, and water quality (temperature, pH, dissolved oxygen, and NH3) had been evaluated. The treatments are K (Control, without supplementation of Spirulina platensis fluor), A (30 g of Spirulina platensis fluor + 1 kg of artificial feed), B (60 g of Spirulina platensis fluor + 1 kg of artificial feed), and C (90 g of Spirulina platensis fluor + 1 kg of artificial feed). The experimental research used completely randomized design with 4 treatments and each 3 replications. The experimental research was carried out on September 2018 until April 2019 at The Fisheries Laboratory, Djuanda University, Bogor. Part of Sangia Research Media (SRM).The research is aimed to know the supplementation effect of different concentration of Spirulina platensis fluor on artificial feed against the growth and feed efficiency of goldfish.

Generally, fish that are given inferent hormone at a dose of 40-60 mg / l can increase the gonad maturity index by 25%, in betok Ambon fish by 30%. The determination of the inferent hormone dosage is based on the determination of the inferent dose in fish, generally around 10 mg - 80 mg or about 0.1 ml - 0.8 ml. Inferent hormone is one type of reproductive hormone that functions to spur and accelerate the level of gonad maturity in animals including fish. The number of eggs produced by Betok Ambon fish varies between 900 and 3,500. Reproduction is the reproduction process in living things including Betok Ambon fish. Review article This aims to reveal the role of the inferent hormone on the aspects of reproduction and growth of Betok Ambon fish. To maintain the sustainability and sustainability of Betok Ambon fish farming, one way to take is to understand and know the growth and reproduction aspects of this type of fish through the provision of inferent hormones appropriately. Cultivation of this fish is quite profitable, and easy to maintain. One type of marine ornamental fish that can be developed through cultivation is betok Ambon fish.
