Background: Natural preservatives are compounds produced by natural ingredients that can suppress bacterial growth and development. Natural preservatives are carried out because most of the preservatives circulating are chemicals and unsafe for the body. One of the natural preservatives is by using garlic extract (Allium sativum L). Objective: This study is aimed to determine the effectiveness of the antibacterial garlic (Allium sativum L) as a natural preservative in fresh African catfish (Clarias gariepinus). Method: This research used the Pour Plate iroculation method. African catfish (Clarias gariepinus) which is soaked with garlic (Allium sativum L) with a concentration of 7%, 14% and 21% for 30 minutes, then the fish will be kept at room temperature with a storage period of 24 hours and 48 hours and calculated growth in bacterial numbers with the Colony counter. Result: Based on the research result, it was found that garlic extract (Allium sativum L) can obstruct the effectiveness of antibacterial in African catfish (Clarias gariepinus) at a concentration of 14%.

Effect of four types of diluentss and four concentration of DMSO (5%, 10%, 15% and 20%) against the motility of African catfish sperm were evaluated after storage at freezing temperatures. The steps in preparation the 16 treatments combination of the diluents are preparation of diluents, mixing diluents with DMSO, packing of semen into 0.3-ml straw, equilibration of semen at 4 °C for 30 minutes, freezing of semen in nitrogen vapor liquid at a height of 6.5 cm for 10 minutes, and subsequently storage of semen in liquid nitrogen (-196 0C) for further analysis of post-thawing motility (PTM). The result showed that the highest level of motility of spermatozoa was in treatment P1D15 (45.7 ± 4.3%) and the lowest was in treatment P2D20 (14.5 ± 13.2%). The best diluent in this observation was diluents containing NaCl, KCl, CaCl2 and NaHCO3. The best concentration was DMSO 15%. While the best interaction between the concentration of DMSO diluents is P1D15 treatments containing NaCl, KCl, CaCl 2 and NaHCO3 with a combination of 15% DMSO concentration. The conclusion of the research is that diluents containing NaCl, KCl, CaCl2 and NaHCO3 with a combination of 15% DMSO concentration can be used in cryopreservation of African catfish semen.

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.

Prolonged Duration

Summary The optimum distance and duration of ultraviolet (UV) irradiation for the complete inactivation of African catfish Clarias gariepinus egg nucleus was investigated in this study. The UV light was suspended above the unfertilized eggs at four distances (5, 10, 20 and 30 cm) and for five durations (1, 2, 3, 4 and 5 min). Then, the irradiated eggs were activated with sperm from diploid C. gariepinus and cold shocked at 5°C for 5 min just moments before cell cleavage. Ploidy analysis was performed using karyotype chromosome counting. The results obtained suggested that the further the distance, the better the hatchability rate, however prolonged duration seemed to significantly reduced hatchability. All treatments with surviving progenies at the end of the study showed evidence of successfully diploid gynogen (2n = 56) induction at different percentages. However, the optimal protocol that gave a moderately high hatchability/survival rate and completely induced gynogens was exposure of the eggs to UV irradiation at 20 cm for 1 min. It was concluded that the distance and duration of UV irradiation affects gynogenetic induction in African catfish C. gariepinus.
