THE PRODUCTION OF COMET-TAILED GOLDFISH Ciprinus auratus AND SEVERAL TYPES OF AQUATIC PLANTS IN AQUAPONICS SYSTEM

Aquaponics is the combination of aquaculture and hydroponics together in one integrated system. In aquaculture, excretions from fish the animals accumulate in the water and increasing ammonia (NH3), nitrites (NO2 and nitrates (NO3). In an aquaponic system, the ammonia, nitrites and nitrates are utilized by the plants as nutrients, and the water is then recirculated back to the aquaculture system. Plants that are common as vegetable reported success in aquaponics, such as cucumbers, shallots, tomatoes, lettuce, chiles, capsicum, red salad onions and snow peas.This study aims to determine the type of aquatic plants to reduce ammonia and to find out water quality for comet-tailed goldfish (Ciprinus auratus).

The plants are reared in glass container filled with 20 liters of ground water and aerated. Each tank were contained of 20 fish.  The researchs were designed in Completely Randomized Design (CRD), 4 treatments and 3 replications. The treatments were different types of aquatic plant, which were (1) Control (2) Echinodorus sp (3) Anubias sp and (4) Bacopa sp. Fish used were Ciprinus auratus (total length 2.79 ± 0.25 cm and weight 0.24 ± 0.083 g). The results showed that the using of aquatic plants improves the water quality by reducing the ammonia (NH3), nitrites (NO2 and nitrates (NO3) in media, especially by reducing the ammonia (NH3) content. However the treatments were no effect on fish growth and survival rate of fish (P> 0,05)
