First report on the successful hybridization ofPangasianodon hypophthalmus(Sauvage, 1878) andClarias gariepinus(Burchell, 1822)

SummaryBreeding and larval performance of novel hybrids from reciprocal crosses of Asian catfishPangasianodon hypophthalmus(Sauvage, 1878) and African catfishClarias gariepinus(Burchell, 1822) were investigated in this study. Spawning was by hormonal injection of brood fish, artificial fertilization, and incubation in triplicate aquarium tanks (0.5 × 0.5 × 0.5 m3) with continuous aeration. Reciprocal crosses (♀C. gariepinus× ♂P. hypophthalmusand ♀P. hypophthalmus× ♂C. gariepinus) had lower hatchability (≤50%) than their pure siblings (≥75%). Fish from all crosses survived until the juvenile stage but survival at 35 days post hatching (dph) was higher for pureC. gariepinussib. ♀C. gariepinus× ♂P. hypophthalmuswas observed to be less resistant to degradation of water quality than the other crosses, however it had higher body weight compared with the other crosses that showed similar performance. Morphological comparison of surviving juvenile at 35 dph, showed that all ♀P. hypophthalmus× ♂C. gariepinusand 13% of the ♀C. gariepinus× ♂P. hypophthalmusexhibited the very same morphology as that of their maternal parent species, while the other portion of the ♀C. gariepinus× ♂P. hypophthalmuscross exhibited morphological traits that were intermediate between those of both parent species. This study been the first successful attempt to hybridize both species and therefore, laid the groundwork for further studies on the aquaculture potentials of the novel hybrids.

African catfish (Clarias gariepinus Burchell, 1822) has become a great important species in Indonesian aquaculture. Several strains of the African catfish have been introduced to Indonesia for aquaculture purposes, initiated by Dumbo strain from Taiwan in 1985, followed by Paiton strain from Thailand in 1998, then Egypt strain from Egypt in 2007, Masamo strain from Thailand in 2010 and later Kenya strain from Kenya in 2011. Since its introductions, there were no reports yet on their characterization studies. The present study was conducted to morphologically characterize the strains of African catfish introduced to Indonesia, i.e. Dumbo, Paiton, Egypt, Masamo, and Kenya strains. Morphometric and meristic data obtained were analyzed using Principal Component Analysis. Results of the morphometric characterization in the present study revealed that Dumbo, Paiton, Masamo, and Kenya strains were indistinguishable, while morphometric characteristic of Egypt strain was more or less different from those of the other strains. On the other hand, results of the meristic characterization suggested that meristic characteristics of all strains of the introduced African catfish were not different from each other. Therefore, to keep the genetic purity of those introduced strains, they should be properly maintained in isolated places.

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.
