“…There was no significant difference (P>0.05) on the survival of the catfish fry among treatments. This was in line with the study by Xu and Pan (2014) that reported treatments with different protein levels in the feed applied on the shrimp juvenile reared in biofloc-based system showed equally good results among treatments. The same result was revealed by Ballester et al (2010) who reported that feeding with different protein levels in the diet did not show any significantly different result on the survival of Farfantepenaeus paulensis among treatments.…”

“…The application of biofloc technology can increase feed utilization efficiency (De Schryver et al, 2008;Ballester et al, 2010;Xu and Pan, 2014). The higher the feed efficiency, the lower the Feed Conversion Ratio (FCR).…”

“…Several advantages resulted in the application of biofloc-based system, including the ability to reduce ammonia (Avnimelech, 2007), the floc aggregate formed in the biofloc-based culture system can be used as natural food sources (Ekasari et al, 2010), the addition of feed nutrients in biofloc-based system is able to increase the growth and feed efficiency (Frame & Gunarto, 2012), flocs have a high protein content (Xu et al, 2012), a reduction in the use of the protein of the feed in the biofloc-based system culture does not interfere the growth and the health status of the shrimp, so that it can be an alternative to decrease the protein level in the feed that is automatically able to reduce the production cost in the hatchery (Xu & Pan, 2014). A decrease in the protein level contained in the diet on the freshwater fish (the catfish fry) culture through biofloc-based system has not been done, so it is necessary to conduct a study to evaluate the growth performance of the catfish fry reared in the biofloc-based system with different protein levels in the diets.…”

The study was conducted to evaluate the performance of catfish fry grown using different dietary protein levels in the biofloc-base aquaculture system. Experiments using a completely randomized design, consisted of four treatments and three replications. The treatment consisted of: protein 38% (A), 34% protein (B), 30% protein (C), and protein 26% (D). Catfish with initial weight of 0.83±0.01 g and length of 4.64±0.04 cm were cultured in 60 L tank with density of 90 fish each tank for 35 days. Inoculation of heterotrophic bacterial Staphylococcus lentus L1k were performed of 10 4 CFU/mL ratio of 15 was administrated once a day after two hours feeding in the morning. Feeding was conducted twice a day at 5% of the biomass weight. At the end of trial treatment (D) showed the highest survival rate (88.15±5.25%), the body lenght variance coefficient (9.58±0.51%) and protein retention (39.87±2.77%). Treatment (B) showed the highest growth rate (4.11±0.05%), total length (2.39±0.08 cm), and feed intake (318.76±4.63). Treatment (A) showed the highest feed efficiency (93.65±4.43%) while lowest lipid retention compared to others (22.20±1.20%.). Based on the results, it can be concluded that 34% protein feed (C) can replace 38% protein feed (B) catfish fry size 4−5 cm through biofloc-based system. Keywords: biofloc, fry, growth, protein, Staphylococcus lentus L1k ABSTRAKPenelitian bertujuan mengevaluasi kinerja pertumbuhan benih lele dengan menggunakan kadar protein pakan yang berbeda pada sistem bioflok. Percobaan dilakukan menggunakan rancangan acak lengkap, terdiri atas empat perlakuan dan tiga ulangan. Perlakuan terdiri atas protein 38% (A), protein 34% (B), protein 30% (C), dan protein 26% (D), terdiri atas empat perlakuan dan tiga ulangan. Benih lele dengan berat rata-rata 0,83±0,01 g dan panjang rata-rata 4,64±0,04 cm dipelihara di akuarium berukuran 90×50×40 cm 3 dengan padat tebar 90 ekor/akuarium selama 35 hari. Inokulasi bakteri heterotrof berupa Staphylococcus lentus L1k dilakukan pada setiap perlakuan kepadatan 10 4 CFU/mL. Penambahan sumber karbon berupa molase dengan C/N (Carbon/ Nitrogen) rasio 15 diberikan satu kali sehari setelah dua jam pemberian pakan di pagi hari. Pakan diberikan dua kali sehari sebanyak 5% dari berat biomasa. Hasil penelitian menunjukkan pemberian kadar protein pakan berbeda memberikan hasil yang positif. Perlakuan (D) menunjukkan tingkat kelangsungan hidup (88,15±5,25%), koefisien keragaman panjang (9,58±0,51%) dan retensi protein (39,87±2,77%) terbaik. Perlakuan (B) menunjukkan laju pertumbuhan harian (4,11±0,05%), panjang total (2,39±0,08 cm), dan jumlah konsumsi pakan (318,76±4,63) tertinggi. Perlakuan (A) menunjukkan efisiensi pakan (93,65±4,43%) tertinggi namun menunjukkan retensi lemak (22,20±1,20%) terendah. Berdasarkan hasil penelitian disimpulkan bahwa pemberian pakan dengan kadar protein 34% mempunyai performa pertumbuhan yang sama dibandingkan protein 38% pada benih ikan lele berukuran 4−5 yang dipelihara menggunakan sistem budidaya bioflok.

“…Similarly, reported that blood Ht of Nile tilapia did not vary statistically between the biofloc treatment and the control group. Furthermore, the total hemocyte count of shrimp did not vary significantly between biofloc-treated and control groups (Souza et al, 2014;Xu and Pan, 2014). In contrast, Xu and Pan (2013) found that the total hemocyte count in shrimp was significantly higher in biofloc treatments than in the control group.…”

The aim of this research is to evaluate the effects of biofloc system application at different fish density on the nursery production performance and the robustness of African catfish Clarias gariepinus (Burchell) against Aeromonas hydrophila and salinity stress. An economic analysis was also performed to determine the most optimum fish density in biofloc-based African catfish nursery production. African catfish with an average body weight of 0.96 AE 0.04 g and average body length of 4.20 AE 0.46 cm, respectively, were distributed in 12 units of circular plastic-lined tanks (1,020 L). The experiment consisted of four treatments in triplicates, that is, a control without carbon source addition at a density of 4 fish/L, and three biofloc treatments at different densities, that is, BFT4 (4 fish/L), BFT6 (6 fish/L) and BFT8 (8 fish/L). Tapioca flour was used as the organic carbon source in biofloc systems and was added at an estimated C/N ratio of 10. Housing the fish in biofloc systems resulted in higher fish growth, more efficient feed utilization, higher fish robustness against A. hydrophila infection and salinity stress, as well as higher profitability of nursery production. Increasing the fish density resulted in higher mortality.However, higher number of fish produced and lower feed conversion ratio were observed in the treatments with higher density (6 and 8 fish/L). In conclusion, the application of biofloc technology at a density of 8 fish/L could be recommended to increase the production and profitability of African catfish nursery culture.
