This research aimed to evaluate the health status, growth performance, and meat quality of African catfish Clariasgariepinus maintained in biofloc and nonbiofloc systems. This study applied 3 treatments with 4 replications, i.e.K500 (control, a non-biofloc system at a fish stocking density of 500/m3), BF500 (biofloc system at a fish stockingdensity of 500/m3), and BF700 (biofloc system at a fish stocking density of 700 /m3). The initial body length andbodyweight of the fish used in this experiment were 10–12 cm and 10–12g, respectively. Feeding was done byusing a commercial feed containing 29.76% protein content. The results showed that fish survival in treatmentsBF500 and BF700 were significantly different (P<0.05) from the control. The growth rate of African catfish in thecontrol (K) was the lowest (3.64 ± 0.56%) among the treatments. The results of the organosensory test showed thatthe application of biofloc systems produced a higher quality of fish meat with a range value of 7–9 compared to thatof the control with a range of 6–7. In conclusion, the application of biofloc systems could improve the fish healthstatus, growth performance, and meat quality of African catfish. Keywords: biofloc systems, Clarias gariepinus, density, health status, meat quality ABSTRAK Penelitian ini bertujuan mengevaluasi status kesehatan, kinerja pertumbuhan, dan kualitas daging ikan lele AfrikaClarias gariepinus yang dipelihara menggunakan sistem bioflok dan nonbioflok. Penelitian ini menggunakan 3perlakuan dengan 4 kali ulangan, yang terdiri dari: K500 (kontrol, sistem nonbioflok dengan kepadatan ikan 500ekor/m3), perlakuan BF500 (sistem bioflok dengan kepadatan ikan 500 ekor/m3), dan perlakuan BF700 (sistembioflok dengan kepadatan ikan 700 ekor/m3). Ikan yang digunakan berukuran panjang dan bobot awal masingmasing10–12 cm dan 10–12 g. Pemberian pakan dilakukan dengan menggunakan pakan komersil dengan 29,76%protein. Hasil penelitian menunjukan tingkat kelangsungan hidup antara perlakuan BF500 dan BF700 berbeda nyata(P<0.05) dengan perlakuan K500. Laju pertumbuhan ikan lele pada perlakuan K500 lebih rendah dibandingkanperlakuan lain. Hasil pengujian organosensory menunjukkan bahwa ikan yang dipelihara dalam sistem bioflokmenghasilkan kualitas daging yang lebih tinggi dengan kisaran nilai 7–9 dibandingkan dengan ikan K500 dengannilai 6–7. Berdasarkan hasil penelitian ini dapat disimpulkan bahwa aplikasi sistem bioflok dapat meningkatkanstatus kesehatan, laju pertumbuhan, dan kualitas daging ikan lele Afrika. Kata kunci: bioflok, Clarias gariepinus, kepadatan, kualitas daging, status kesehatan

In the present study, a possible nature immunostimulant and growth promoter—humic substances (HS) originating from Siberian leonardite mineraloid—were tested on juvenile Clarias gariepinus performance. Feed additive was applied onto commercial pelleted feed at four HS levels—0, 1, 3, and 6% w/w (HS0, HS1, HS3, HS6, respectively). Diets were tested in five repetitions (in total, n = 1800 individuals, mean body weight 28.1 ± 6.2 g) for 56 days. Growth and production parameters, fish condition and somatic indices, and overall mortality were evaluated after 14, 28, 42, and 56 days of exposure. Whereas, plasma samples were collected only after 0, 28, and 56 days, when fish health status was assessed with biochemical parameters (total proteins, TP; alanine aminotransferase, ALT; aspartate aminotransferase, AST; lactate dehydrogenase, LDH; cholesterol, CHOL; triglycerides, TAG) and fish antioxidant status with glutathione (reduced glutathione, GSH; oxidized glutathione, GSSG; glutathione ratio GSH/GSSG). Although a significantly positive effect of HS feed additive on growth performance was not found in the present study, moderately positive effects were found regarding biochemical parameters (ALT, AST, LDH, CHOL, and TAG) and antioxidants (GSH/GSSG ratio) that were improved especially in the HS3 group.

The objective of this research was to evaluate the supplementation of turmeric in the diet on antioxidant status and growth performance of African catfish (Clarias gariepinus) in zero water exchange condition. This study used a completely randomized design with 4 treatments and 4 replications. Each treatment consisted of feed supplementation turmeric at dosage of 0; 2.5; 5 or 7.5 g kg-1 diet. One hundred catfish juvenile (5.95±0.05 g) were stocked in intermediate bulk container (IBC) tank (1×1×1 m3) and rearing in zero water exchange condition for 60 days. Catfish were fed at satiation twice a day, in the morning and evening. The results showed that an increase in antioxidant content in catfish fed with the addition of turmeric, which simultaneously also reduced the percentage of liver damage. The parameters of liver damage can be seen from several parameters i.e. pale liver, droplet fat and fat content in the addition of turmeric treatment is lower than without the addition of turmeric. However, catfish fed with the addition of turmeric did not show significant results in terms of growth performances.
