The search for alternative protein sources in aquaculture nutrition is still trending as the use of costly traditional feed stuffs in aquaculture diet formulation is no longer sustainable. The present study investigated the effects of partial and total dietary inclusion of cashewnut meal on growth, haematology, carcass composition, serum biochemistry and intestinal histology of juvenile African catfish Clarias gariepinus (Burchell, 1822). Soybean meal (SBM) was substituted with cashewnut meal (CM) at 0, 50 and 100% in formulated fish diets. A total of 135 juveniles of C. gariepinus (30.25± 1.02 g; 16.08±0.34 cm) were randomly assigned to three dietary treatments (0, 50 and 100% CM based diets) at a stocking density of 45 fish per treatment and further randomised into triplicates of 15 fish per replicate. The feeding trial lasted for 56 days and fish were fed twice daily at 5% body weight. Statistical analysis was carried out for all the parameters evaluated in this study. Fish group fed 50% CM based diet had the best growth performance and haematological profile when compared to 100% CM fish group and the control group. Insignificant changes in serum biochemical parameters were observed in CM fed fish groups when compared to the control. Histological examination of fish intestinal morphology revealed no adverse changes in the cellular structure of mucosal layer and villi in 50% CM fed fish, while mild histo-morphological changes were observed in 100% CM fed fish group. Significant increases in villi length and weight were observed in fish group fed CM based diets when compared to the control. The findings of the present study revealed that partial replacement (50%) of soybean with cashewnut meal improved growth performance and haematological profile of C. gariepinus.

Growth performance, feed utilization, survival and body indices of African catfish Clarias gariepinus juveniles fed diets containing maggot meal as replacement of fish meal was evaluated for 42 days. Sixty fingerlings of Clarias gariepinus, average weight of 10 g were randomly distributed into six circular tanks at the rate of 10 fish per tank. There were two treatments, DT1(maggot meal-based diet) and DT2 (fish meal-based diet). The fish were fed twice daily. Water quality parameters were monitored on a weekly basis throughout the experimental period. Growth, nutrient utilization and body indices parameters were evaluated at the end of the experiment. Crude protein, crude lipid and ash were higher in the fish meal-based diet (34.65%, 7.33% and 18.03% in DT2 as against 28.70%, 7.20% and 11.0.1% in DT1 respectively), while crude fibre was higher in maggot meal-based diet. The selected water quality parameters: temperature, dissolved oxygen, ammonia and pH were slightly lower in maggot meal based treatment, but none of them was differently significant. Mean weight gain, specific growth rate, protein intake, protein efficiency ratio, lipid intake and lipid efficiency ratio (17.25±0.70 g, 2.39±0.06 %/day, 95.50±1.27 g, 1.81±0.06, 23.96±0.32 g and 7.20±0.24 respectively) were all significantly higher in DT2. The feed conversion ratio was higher significantly in DT1. Survival, hepatosomatic index and condition factor were similar between the two treatments. Though the aforementioned body indices indicated that the total replacement of fish meal with maggot meal is not harmful to the fish, a partial replacement may be better for optimum output

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.

AbstractThe feed as a source of energy for the growth of fish is a component of the most important costs 40-89% and the quality should be good. The solution is through research. Research in the form of meal cassava leaves (Monihot utilissima) parents as a source of alternative protein substitute for fish meal in feed formulation catfish (Clarias gariepinus). The design used Complete Random Design with 4 treatments and 3 repetitions. The results showed that for the growth and the survival between treatments were not significant (P <0.5), meaning that all treatments were no differences can be categorized and feed ingredients of flour cassava leaves can replace most of the presence of meal fish  in fish feed formulas African catfish. Growth of the best catfish are on treatment A (55% meal cassava leaf: 00% fish meal) with daily growth of 8.27 grams was 2.61% and the B (40%% meal cassava leaves: 15% meal fish) 5.28 gram with daily growth is 1.86%, followed by C (15%%  meal cassava leaves: 15% meal fish ) 1:51% and D (0% meal cassava leaves : 55% meal fish ) 1:33%. Catfish survival rate was not significant (P <0.5), and relatively equally well A (96.17%), B (94.77) and C (95.92) and the best in treatment for D (96.37 ). As users are advised to wear formulations in treatment B (40% meal fish and 15%  meal cassava leaves old). Keywords: Catfish, Ffeed, Meal fish, Meal cassava leaves AbstrakPakan sebagai sumber energi bagi pertumbuhan ikan  merupakan komponen biaya yang paling besar 40-89%  dan kualitasnya harus baik. Solusinya melalui penelitian. Penelitian berupa tepung daun  singkong (Monihot utilissima) tua sebagai sumber protein alternatif penganti tepung ikan dalam formulasi pakan ikan lele (Clarias gariepinus). Rancangan digunakan Rancangan Acak Lengkap dengan 4 perlakuan dan 3 kali ulangan. Hasil penelitian menunjukan bahwa untuk pertumbuhan dan kelulusan hidup antar perlakuan tidak signifikan (P < 0,5), artinya semua perlakuan  tidak ada perbedaan dan dapat dikatagorikan bahan pakan dari tepung daun singkong dapat mengantikan sebagian keberadaan tepung ikan dalam formula pakan ikan lele dumbo. Pertumbuhan ikan lele terbaik terdapat pada perlakuan A (55% tepung daun singkong : 00% tepung ikan) 8,27 gram dengan pertumbuhan harian adalah 2.61% dan  pada B (40%  % tepung daun singkong : 15% tepung ikan) 5,28 gram dengan pertumbuhan harian adalah 1.86%, diikuti C (15% % tepung daun singkong :15% tepung ikan) 1.51% dan D (0 % tepung daun singkong : 55% tepung ikan) 1.33%. Tingkat kelangsungan hidup ikan lele tidak signifikan (P < 0,5), dan  relatif sama baiknya A (96,17%), B (94,77) dan C (95,92) dan terbaik pada perlakuan untuk D (96,37). Sebagai pengguna disarankan memakai formulasi pada perlakuan B (40% Tepung ikan dan 15% tepung daun singkong tua). Kata kunci: Ikan lele, Pakan, Tepung ikan, Tepung  Daun Singkong Tua
