Production Performance of Catfish (Clarias gariepinus Burchell, 1822) Cultured With Added Probiotic Bacillus sp. on Biofloc Technology

Abstract

Biofloc technology (BFT) is one of the most developed aquaculture technologies, which aims to improve the efficiency of feed use by providing nutrients for flocs to be used by fish as a supplementary feed. Also, BFT serves to improve water quality through the breaking down of fish waste materials assisted by heterotrophic bacteria. Bacteria used in this study were Bacillus sp. as probiotics in BFT. This study aimed to examine the production performance of catfish maintained with a biofloc system on an industrial scale, without experimental design. The average weight of catfish when stocking was 5.9 ± 0.0 g/fish with a density of 7000 fish in 9 unit circular ponds. This studies showed after 78 days of culture, bodyweight gain about 28.6 g/fish to 41.7 g/fish, highest specific growth rate was K2 (2.4 ± 0.2% BW/day), the highest survival rate K2 (98.87 ± 6.64% BW/day), highest grow rate K1 (41.7 ± 5.8 g) and the best FCR K9 (0.95 ± 0.11).

Pemanfaatan Kubis sebagai Bahan Pakan Buatan untuk Pertumbuhan Benih Ikan Lele Mutiara (Clarias gariepinus)

“…Dalam kegiatan budidaya, hal yang harus diperhatikan adalah pertumbuhan ikan budidaya (Pratiwi et al, 2020). Pertumbuhan ikan dipengaruhi oleh pemberian pakan (pakan alami maupun pakan buatan) dan lingkungan media pemeliharaan kualitas air).…”

Feed efficiency with the addition of probiotics for asang fish fry, Osteochilus vittatus, CV

“…The quality of the feed is very important in maintaining survival (Bulanin, 2002). The results on the survival of feed containing probiotics are generally high, for example in the case of tilapia in the range of 80 to 98.50% (Arsyad et al, 2015;Ulfira, 2018;Umasugi et al, 2018;Harmilia et al, 2019 andOpiyo et al, 2019), for catfish, generally above 80% (Wardika et al, 2014;Fadholi et al, 2016;Pratiwi et al, 2020), depik fish seeds 60 -100% (Fratiwi et al, 2018), commond carp 86 -100% (Tarigan and Meiyasa, 2019), giant gouramy 57.50% (Suminto and Cilmawati, 2015) and silver catfish 51.67 -73.33% (Khotimah et al, 2017). The differences in the existence and the survival of the fish fed with probiotics are certainly influenced by various factors including stocking density, fish size, and species.…”

“…To improve the quality of commercial feed, nutritionists add a variety of ingredients, including probiotics, and the addition of probiotics to animals feed has been attempted. Because probiotic The results of previous research also show that the addition of probiotics to commercial feed affects growth and survival, for example, tilapia, Oreochromis niloticus (Ulfira, 2018 andHarmilia et al, 2019); depik fish, Rasbora tawarensis (Fratiwi et al, 2018); zebrafish, Danio rerio, (Rane and Markad, 2013); yellow perch fish, Perca flavescens, (Shaheen et al, 2014); catfish, Clarias gariepinus, (Wardika et al, 2014;Pratiwi et al, 2020) Clarias batracus, ; and common carp, Cyprinus carpio, .…”

STUDI KESESUAIAN KUALITAS AIR UNTUK BUDIDAYA IKAN LELE DUMBO (Clarias gariepinus) DI KAMPUNG LAUK KABUPATEN BANDUNG

“…Niali pH rendah (keasaman yang tinggi) berpengaruh terhadap turunnya niali kandungan oksigen terlarut, akibatnya konsumsi oksigen oleh organisme perairan menurun, aktivitas pernapasan naik dan selera makan akan berkurang (Tokah et al, 2017). Perlakuan yang dapat dilakukan untuk meningkatkan nilai pH yang sesuai dengan prinsip biosekuriti adalah dengan menambahkan kapur ataupun air kapur kedalam media pemeliharaan (Pratiwi et al, 2020). Nilai rata-rata kandungan ammonia diseluruh stasiun menunjukan nilai dari 0,01 mg/l dan nilai tersebut sesuai dengan SNI 01-6484.5:2002.…”

“…Pengaruh pH pada toksisitas ammonia telah dikonfirmasi oleh penelitian pada ikan lele belang bahwa toksisitas NH3 meningkat ketika pH meningkat (Phuong et al, 2014). Amonia beracun bagi ikan karena bila di perairan terlalu jenuh dengan ammonia, ikan tidak dapat melepaskan amonia dari berupa urine atau feses dari tubuh sehingga ikan teracuni ammonia dari dalam (Pratiwi et al, 2020). Sumber ammonia di perairan dipengaruhi oleh adanya proses pemecahan nitrogen organik dan anorganik yang terdapat di dalam tanah dan air yang berasal dari dekomposisi bahan organik termasuk diantaranya hasil ekskresi biota (feses) dan sisa pakan yang tidak termakan (Efendi, 2003).…”
