Use of fluted pumpkin (Telfairia occidentalis) leaf powder as feed additive in African catfish (Clarias gariepinus) fingerlings

A feeding trial was carried out for 56 days to ascertain the effects of Telfairia occidentalis (fluted pumpkin) as a feed additive on the haematological profile and nutrients value of Clarias gariepinus carcass. C. gariepinus fingerlings (mean body weight 9.6g) were randomly distributed in plastic bowls at nine fish per bowl in triplicates. Five diets designated as D1 to D5 with 40% crude protein containing 0, 50, 100, 150, and 200g/kg of T. occidentalis leaf powder were fed to C. gariepinus fingerlings at 5% body weight per day. The results showed that T. occidentalis additive significantly (P≤0.05) improved the haematological parameters of the fish. The mean value of white blood cells (WBC) count (μL) in the diets fed with T. occidentalis were significantly higher (D2-D5 : 870.20, 864.80, 840.30, 876.40, respectively) than the diet without T. occidentalis (D1 783.15). A similar trend was observed in PCV, MCV, MCHC, MCH, and platelets. However, HB D1 (control) had higher values than the diet containing T. occidentalis. Meanwhile, in carcass quality, there was an increase in the crude protein of all the fish but the group that consumed T. occidentalis had a higher carcass crude protein and lower lipid, while the control had a higher lipid value. Meanwhile, the initial values obtained before the feeding trials had lower crude protein and higher lipid value when compared with the fish that was fed with the experimental diet. In conclusion, T. occidentalis leaf meal can be utilized to improve the haematological parameters of the fish, with an increase in the WBC there is a high possibility of the fish to withstand pathogenic attacks because Blood is a major parameter that determines the physiological, immune , and nutritional status of an organism, also WBC are important blood constituents for defense against diseases, pathogens and unwanted foreign bodies in an organism.

Positive Effects

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.

Talinum Triangulare

The effects of Talinum triangulare on the haematological indices of Clarias gariepinus was investigated. T. triangulare leaf powder at 0, 0.5, 1.0, and 3.0% concentrations were fed to Clarias gariepinus juveniles (n=84; 117.3 ± 1.57 g; 26.70 ± 0.26 cm) as feed additive for a period of six (6) weeks. The packed cell volume (PCV) and Haemoglobin (Hb) concentration values, 34.67 ± 0.67%, 12.03 ± 0.26g/dl, respectively observed in the group fed with 1.0% were significantly higher (P<0.05) compare with the control group. Red blood cell counts (RBCs), white blood cell counts (WBCs), lymphocytes, MCV, MCH and MCHC recorded were marginally different (P>0.05) among the groups, were within standard for Clarias gariepinus, therefore adjudged not to indicate a negative physiological effect on the experimental fish. Blood indices values observed revealed that the varying additive levels of T. triangulare used had no negative physiological stress on the health status of the fish studied and haematological values observed were seen to be best in the group fed 1.0% T. triangulare. It could be recommended that 10g/kg of Talinum triangulare leaf powder be included in the diet of Clarias gariepinus for boosting of the animal blood and treatment of disease conditions such as anaemia.

Metabolic Activities

Abstract Here an indigenously isolated microalgal strain Ascochloris spp. cultivated in synthetic medium was evaluated as an aquaculture feed supplement. The daily dietary supplement includes microalgal feed (AF) and commercial diet feed (CF) (as control), respectively. These diets were fed separately to the juvenile Clarias gariepinus fishes (n = 4) under controlled conditions for an experimental period of 100 days. The protein, glycogen and lipid contents in the muscle extracts were found to be marginally higher in fishes that were fed with CF than AF diet. Similarly, CF fishes showed significantly higher glutathione-s-transferase, catalase, superoxide dismutase, and lipid peroxidase activities, except glutathione content. Zero mortality of the fishes with no significant difference in the overall body mass with the two dietary supplements strongly suggests that algal biomass could supplement the requisite nutrients for their metabolic activities. This preliminary investigation helps in exploring algal biomass as a potential alternative feed additive in the aquaculture industry.
