The cultivation of catfish using the biofloc system produces waste in the form of remaining ponds that can be used for aquaponic farming systems. The combination of fermentation between catfish waste and chicken manure affects the growth of kale, lettuce, pakcoy, and spinach with an aquaponic system. This research was conducted in the ALC (Agro Learning Center) garden in collaboration with the Master of Agricultural Science Study Program, Postgraduate Program of Warmadewa University. The parameters observed were plant height, number of leaves, fresh weight, and oven dry weight. The best results for plant height are found in spinach plants. The best number of leaves is found in pakcoy plants. As for fresh weight and dry weight the best results were on pakcoy plants. The best concentration of combination of catfish waste fermentation with chicken manure is at a concentration of 1400 ppm.
The Production of Catfish and Vegetables in an Aquaponic System
Fisheries and Aquaculture Journal, 2016
Aquaponic is a system that mutually integrates aquaculture and plant cultivation (by means of hydroponic). Both crops are combined in a recirculating system that utilizes less water than the traditional farming. Nutrients contained in fish tanks are recycled into plant biomass with the presence of nitrifying bacteria that convert the excreted ammonia to nitrite and then to nitrate. In this study, fifteen sets of aquaponic system were developed to study the growth of African catfish (Clarias gariepinus) and three types of plants; the red and green-red amaranth (Amaranthus spp.) and water spinach (Ipomoea aquatica). The combination of aquaculture and hydroponic gives a new insight into increasing the efficiency of food production which respects principles of sustainable agriculture.

Aquaponics is the cultivation of fish and plants in a series of systems, either in one container or in separate containers, by paying attention to the balance between fish, plants, and aquatic microorganisms. One of the obstacles in aquaponic activities is that vegetable growth is not optimal due to a lack of dissolved nutrients, so further research is needed to make better plant growth. This study aimed to evaluate catfish and water spinach growth performance in an aquaponic system by adding AB mix nutrients at different fish stocking densities. This study used a completely randomized design with three differences in stocking densities of catfish (150 fish/m3, 200 fish/m3, and 250 fish/m3) as test animals with four replications where AB mix was added to each treatment. The growth performance of catfish is better in control with a stocking density of 250 fish/m3 and without adding nutrients. The growth performance of catfish decreased with the addition of AB mix nutrients, while the...

The culture of fish and vegetable plants in aquaponic ebb-tide system is based on the principle of zerowaste aquaculture. The purpose of this study is to see how effective the use of different vegetable plants in an aquaponic ebb-tide system for intensive culture. As much as 3000 catfish (Clarias sp.) were stocked per pond (measuring 4 x 2 m 2), with individual lengths of 8-10 cm. A completely randomized design (CRD) with three treatments and three replications was used in this study. With 60 days of observation, the research treatments included a variety of vegetable plants: (A) water spinach, (B) caisin, and (C) no plants (control). Absolute weight gain and survival rate, water physico-chemistry parameters, Total N and Total P analyses on vegetable plants among the observation parameters. Treatment was found to have the highest average weight gain and survival rate (73.63 g and 87.41%, respectively). Water spinach biomass was 102 kg at the end of the study, whereas caisin biomass was 72.54 kg. Total N and Total P absorption percentages in water spinach were 38.72% and 54.43%, respectively, while 36.00% and 49.55% in caisin. The catfish condition factor showed correlation coefficients with fish weight R2 = 0.978, R2 = 0.956, and R2 = 0.357 and R2 = 0.892, R2 = 0.8215 and R2 = 0.369 for length in the water spinach, caisin, and control treatments, respectively. This study's analysis of water quality parameters indicated that the A treatment had the lowest levels of ammonia, nitrite, and nitrate when compared to the B and C treatments.

Aquaponics is the combination of aquaculture (fish) and hydroponic cultivation of plants. This review examines fish welfare in relation to rearing water quality, fish feed and fish waste and faeces to develop a sustainable aquaponic system where the co-cultured organisms, fish, bacteria in biofilters and plants, should be considered holistically in all aquaponics operations. Water quality parameters are the primary environmental consideration for optimizing aquaponic production and for directly impacting fish welfare/health issues and plant needs. In aquaponic systems, the uptake of nutrients should be maximised for the healthy production of the plant biomass but without neglecting the best welfare conditions for the fish in terms of water quality. Measures to reduce the risks of the introduction or spread of diseases or infection and to increase biosecurity in aquaponics are also important. In addition, the possible impacts of allelochemicals, i.e., chemicals released by the plants, should be taken into account. Moreover, the effect of diet digestibility, faeces particle size and settling ratio on water quality should be carefully considered. As available information is very limited, research should be undertaken to better elucidate the relationship between appropriate levels of minerals needed by plants, and fish metabolism, health and welfare. It remains to be investigated whether and to what extent the concentrations of suspended solids that can be found in aquaponic systems can compromise the health of fish. Water quality, which directly affects fish health and well-being, is the key factor to be considered in all aquaponic systems.

Aquaponics is emerging as an alternative for high-health food production. Being able to identify the technical viability of non-conventional plants and fish species would help to increase the interest and possibilities in aquaponic systems. The goal of the present study was to evaluate the aquaponics production of two garnish species: scallion (S) and parsley (P), using effluents of pacu and red tilapia culture. Two aquaponics devices were used, differing according to the fish species, generating two different effluents. Thus, for plant performance, four treatments were evaluated in a factorial design (plant species and fish effluent as main factors), as followed: Pacu-S, Tilapia-S, Pacu-P, and Tilapia-P, with three replicates each, for 35 days. Fish performance was evaluated using Student's t test. Each experimental device included a fish tank, filters, and six experimental units for the plants (floating rafts). Results

Response of Lettuce (Lactuca sativa L.) To Aquaculture Wastewater Treatment
Journal of Tropical Crop Science
The fish feed waste and litters are organic matter that can be a source of nutrients for plants. This study is aimed to determine the growth and production of lettuce (Lactuca sativa L.) treated with wastewater from hard-lipped barb culture of several population densities. The research was carried out from April through June of 2020 at the greenhouse of the Agrotechnology Study Program, Faculty of Agriculture, Djuanda University, Bogor, Indonesia. The controlled study used a randomized block design with one factor, wastewater from fish population density of 10, 20 and 30 per 21 L of water, and AB Mix as a control. Plants treated with the AB Mix were significantly superior to those plants treated with the hard-lipped barb farming wastewater, demonstrated by taller plants, more and larger leaves, larger stem diameter and leaf area, longer roots, greater fresh and dry weight, as well as a higher leaf nitrate content. The aquaculture wastewater at the tested fish density in this study d...

An experiment was conducted at the Asian Institute of Technology, Thailand, for 54 days to investigate on the effect of pond water filtration and aggregates (hydroponic substrates) on lettuce (Lactuca sativa L.) production, nutrient uptake and growth. A 2 × 3 factorial experiment consisting of 2 filtration regimes (unfiltered versus partially filtered pond water) and 3 aggregates (styrofoam as control, sand, and gravel). The hydroponic units were placed on a bamboo platform across the pond surface. An earthen pond (226 m 2 ) was stocked with 8000 hybrid catfish with an average initial weight of 6.58 ± 1.72 g. The fish were fed with commercial pelleted feeds containing 30% crude protein. Twenty-one days old lettuce seedlings were transplanted on to hydroponic units after stocking catfish for 4 months in the pond. Pond water was partially filtered by using a settling tank and filtration tank, which contained netting materials to trap solids. Lettuce plots were irrigated twice daily at 0800 and 1600 h using either filtered or unfiltered pond water for 45 min.

Water quality and waste management are significant problems for aquaculture in Indonesia, including catfish (Clarias gariepinus) aquaculture. A combination of Aquaponics Systems and Recirculating Aquaculture Systems (A-RAS) has been developed to address this problem. This study analyzed A-RAS application for catfish (Clarias gariepinus) aquaculture by comparing water quality and production indicators between A-RAS and conventional methods. The results show that temperature, pH, dissolved oxygen, total organic matter, ammonia, nitrate and nitrite in A-RAS technology were 28.0-30.0°C, 6.5-7.9, 3.8-7.8 mg/L, 18.54-24.97 mg/L, 0.12- 0.28 mg/L, 0.12-0.13 mg/L, and 0.04-0.13 mg/L, respectively. Survival Rate, Feed Conversion Ratio, and harvest in A-RAS application were 85.5%, 1.1, and 26 kg/m³, respectively. A-RAS technology can maintain water quality to be reused in cultivation and increase yields by about 13%. Besides, water spinach can be an additional income for farmers.
