Water Quality in the Cultivation of Catfish (Clarias gariepinus) and Nile Tilapia (Oreochromis niloticus) in the Aquaponic Biofloc System

Abstract

Aims: Water quality is one of them being an important role in terms of cultivation. Good water quality can support growth productivity in aquaculture. This is also of great concern when the rest of fish metabolism results that can contaminate fish contained in the maintenance media and if water is changed every day, water carrying toxins can pollute the area around the cultivation. One of the first steps to reduce the toxic content found in the maintenance media and the area around cultivation is to use aquaponic cultivation using biofloc. It is also expected to minimize the toxin content in maintenance media. This research aims to determine the comparison of the polyculture stocking density of sangkuriang catfish and nile tilapia which results in water quality that supports fish productivity.
 Study Design: The research was conducted experimentally.
 Place and Duration of Study: This research was carried out for 40 days between March 2019 - April 2019 in the Ciparanje Laboratory of the Faculty of Fisheries and Marine Sciences, Universitas Padjadjaran.
 Methodology: The method used in this research is experimental using a completely randomized design (CRD), consisting of 5 treatments with 3 replications. The treatments to be given are dense stocking variations with the following treatments: A(75 catfish:75 tilapia), B(100 catfish:50 tilapia), C(125 catfish:25 tilapia), D(150 catfish), E(150 tilapia).
 Results: Water Quality Measured During The Study Namely, DO, Temperature, Ph, Nitrite, Nitrate And Ammonia Are Still In The Threshold For The Growth Of Test Animals During Maintenance.
 Conclusion: Based on the results of the research that has been done, it can be concluded that the quality of water in maintenance media using aquaponics biofloc gives good water quality values on maintenance media and is still within the threshold for the growth of catfish and tilapia.

Substitution of Hibiscus sabdariffa with Curcuma longa in the Diets of Clarias gariepinus and the Effects on the Growth, Nutrient, and Hematobiochemistry

“…The dissolved phosphorous content of the water ranged from 2.56 ± 0.12 mg L -l to 3.95 ± 0.77 mg L -l (Table 6). The recorded data showed that the physiochemical parameters of the culture water were within acceptable values and in line with Hussain et al (2014), Ariffin et al (2019), and Zidni et al (2019 who had similar water quality. The water quality could have supported the growth rate of the fish especially as the water was changed daily.…”

Pengaruh Penambahan Larutan Kencur (Kaempferia galanga) Pada Pakan Komersial Terhadap Pertumbuhan dan Kelulushidupan Benih Ikan Lele (Clarias sp)

“…Habitat yang paing penting bagi kehidupan ikan adalah air. Faktor kualitas air yang dapat mempengaruhi proses dalam metabolisme ikan dan mempengaruhi lingkungan adalah faktor fisika dam faktor kima (Zidni et al, 2019). Faktor penentu dalam keberhasilan kegiatan budidaya adalah parameter kualitas air sebab dengan kualitas air yang dikatakan sesuai maka ikan dapat terhindar dari penyakit maupun stress yang akan mengakibatkan kematian pada ikan yang dipelihara.…”
