Abstract

Fish culture activities usually release wastes to environments such as faeces, urine, uneaten food and other by-product metabolism activities. For increased water quality, ideally in aquaculture media, various methods could be used, such as filtering techniques and sinking and dissolving methods. Various filter materials could be used to increase water quality, such as silt, gravel, charcoal, coconut shell, palm fiber, and zeoliteThe study on the effect of recirculation systems using various filter materials and aquaponic systems on water quality has been carried out. Several filter materials were used in four kinds of treatment,  namely aquarium using aerators (control), aquarium using silt, gravels and palm fiber (recirculation), aquarium using mustard greens (aquaponic system) and aquarium using spoons (recirculation). The study results showed that different filter materials significantly affected nitrate and nitrite concentration in the catfish culture media. It was invented that the treatment of a recirculation system combined with an aquaponic system could increase water quality parameters such as  CO2 (7.99 - 11.98 mg.L-1), NH3 (0.02 - 0.07 mg.L-1), NO2 (2.43 - 0.02 mg.L-1), NO3 (4.32 - 0.04 mg.L-1) respectively. Still, the other water quality parameters were similar. The best results were achieved at the same treatment, namely absolute growth rates  (4.01 g), daily growth rates  (1.96 %) and survival rates (91.11 %), respectively

Abstract

This study aims to determine the growth and survival of kissing gourami (Helostoma temminckii) on a rearing medium given liquid biological fertilizer. This research was conducted from 01 April to 21 May 2022 at the Hatchery, Faculty of Fisheries and Marine, Universitas Riau. The container used was a bucket with a volume of 100 L. This study used a one-factor, Completely Randomized Design (CRD) method with five treatments and three replications. The level of treatment applied in this study was P0 = No treatment, P1 = treatment of 0.01 mL/L water, P2 = treatment of 0.03 mL/L water, P3 = treatment of 0.05 mL/L water and P4 = treatment of 0.07 mL/L. The results showed that applying liquid biological fertilizer with different doses significantly affected fish growth performance (P<0.05). The best treatment was found at a dose of 0.03 mL/L, which produced a range of ammonia (0.0043-0.0163 mg/L), nitrate (0.049-0.189 mg/L) phosphate (0.036-0.072 mg/L), absolute weight growth (10.07 g), absolute length growth (11.31 cm), specific growth rate (1.94%), feed conversion (1.08%) and survival (85, 00%).

Abstract

Tambaqui (Colossoma macropomum) is a highly promising aquaculture commodity, yet intensive cultivation produces excessive organic waste that degrades water quality. The Recirculating Aquaculture System (RAS) serves as an effective solution for managing water quality through filtration, the performance of which depends heavily on the filter's design and layout. This study aimed to determine the effectiveness of various filter layouts on water quality stability, growth performance, and survival rates of tambaqui reared in a recirculating system. This experimental study employed a Completely Randomized Design (CRD) with 4 treatments and 3 replications, including layouts with no filter/control (P1), vertical (P2), horizontal (P3), and a vertical-horizontal combination (P4). The rearing process was conducted for 50 days at the Aquaculture Technology Laboratory, Universitas Riau. The results demonstrated that the combination filter layout (P4) yielded the best performance, achieving an average absolute weight gain of 10.71 g, absolute length gain of 6.81 cm, specific growth rate of 3.58%, feed efficiency of 83.33%, feed conversion ratio of 1.18, and a survival rate of 100%. Water quality parameters in P4 also exhibited the highest stability, with temperatures of 26.9–29.4°C, pH 6.1–7.3, dissolved oxygen 4.50–6.00 mg/L, ammonia 0.007–0.022 mg/L, nitrite 0.038–0.044 mg/L, and nitrate 0.131–0.366 mg/L. It can be concluded that the implementation of a recirculating system with a combination filter layout (vertical-horizontal) is the most effective treatment for optimizing water quality, thereby significantly enhancing the somatic growth and feed utilization efficiency of tambaqui.
