Abstract

Lele Dumbo was used to be a superior clariid catfish ardely cultured in Indonesia. Despite its aquaculture success, there was uncertainty about its taxonomic identity, whether it belongs to an African catfish (Clarias gariepinus Burchell 1822) or a hybrid resulted from a hybridization between African catfish C. gariepinus and an Asian catfish C. fuscus. Though lele Dumbo was no longer popular, the genetic improvement program has successfully developed lele Sangkuriang strain, and that have recently been extensively cultivated in Indonesia. As a lele Dumbo strain, the identity of lele Sangkuriang is also uncertain, thus need to be verified. The present study aimed to investigate the similarity of lele Dumbo through morphometric and meristic characterizations using samples of lele Sangkuriang (collected from BBPBAT Sukabumi, BPBAT Cijengkol and PT STP) compared to those of African catfish C. gariepinus introduced from Thailand and Kenya. The characterizations were carried out through measurement of 20 standard morphometric characters and five meristic characters the data obtained were then analyzed using principal component analysis. The results suggested that the values of morphometric and meristic characters of all three samples of lele Sangkuriang were not different from those of African catfish C. gariepinus. Likewise, the results of principal component analysis performed on morphometric and meristic characters also revealed that morphometric and meristic characteristics of all three samples of lele Sangkuriang were not different from those of African catfish C. gariepinus. Those results revealed that biometric characteristic of both lele Dumbo and African catfish C. gariepinus was not different, thus they seem belong to the same species.

Abstract

Fisheries output need tobe increased to meet the rising demands for fish incomingyears as the increasing of human population. Biotechnology approach has used forincreasing production on aquaculture sector. One of the advances biotechnologies thatused for aquaculture development is transgens technology. Transgenic fish is a speciesthat experience alteration of genetic structure that introduced from other organisms,with the result that change the their genetic function in accordance with the introducedgene. One of the things that support the development of transgenic fish strain formationis the ability of individual transgenic to bequeath the transgenes to the next generation,so that the genetic trait target genes stable in the resulting offspring. This study aims todetect and determine the expression of growth hormone gene (PhGH) on dumbo catfish(Clarias gariepinus) transgenic F3. Transgene detection performed on embryos andlarvae of catfish transgenic F3 using PCR with primers ACT 107 and PhGH2.Transgene expression was analyzed by using reverse transcriptase polymerase chainreaction (RT-PCR) methods with primers β-actin and ACT 107 and PhGH2. Theresults showed that the transgene was detected in some of the embryos and larvaeaccording to Mendel principle. β-actin primer amplification compared to primary ACT107 and PhGH2 showed that transgene can be expressed in some of the embryos andlarvae.Keywords: biotechnology, aquaculture, transgenic, detection, expression, growthhormone

Abstract

African catfish (Clarias gariepinus Burchell, 1822) transgenic containing Pangasius hypothalmus Growth Hormone (PhGH) has better performance compared with non-transgenic. However, before transgenic African catfish are released and utilized, their genetic impact on the natural environment must be examined. Predator avoidance is one of the major fitness traits determining potential environment risk. Transgene detection was performed using the PCR (Polymerase Chain Reaction) method and electrophoresis. Furthermore, the observation of the performance of growth including the growth of the length (the average length of the fish at the end - the average length of the fish at the beginning), the growth in weight (average weight of fish in the end – average fish at the beginning) and the survival rate (the number of fish that live in end / number of fish lived at the beginning). Results indicate that non-trangenic had better predator avoidance than transgenic African catfish. Non-transgenic has a better growth performance than transgenic African catfish and has a higher survival rate. Transgenic African catfish could be used for commercial aquaculture without affecting the natural environment because the increased susceptibility of transgenic to predators would most likely decrease or eliminate the transgenic genotype.Keywords: Clarias gariepinus, Transgenic, Environmental Risk

Abstract

Fish increasing in aquaculture production requires the fulfillment of the need toaccelerate the productivity. Transgenesis technology with the introduction of transgenes(PhGH) can be performed to produce the fish that grow faster and has better performance.Transgene detection was performed using the PCR (Polymerase Chain Reaction) method andelectrophoresis using seed of transgenic catfish F-3. Furthermore, the observation of theperformance of catfish transgenic F-3 by measuring the rate of fertilization (the number offertilized eggs / total eggs), hatchability rate (the number of hatched eggs / number offertilized eggs), the survival rate (the number of early fish / amount of fish end), theperformance of growth (weight average transgenic F-3 / weight average non-transgenic) andfeed efficiency (absolute growth rate / daily feed intake). Results indicate that thetransmission rate ranged from 5-75% with an average transmission in the female transgenikF-2 by 2.5% (15/600) and 14.4% (75/520) in the male transgenik F-2. Weight growth rate of1.7 fold compared with non-transgenic. F-3 transgenic catfish has a degree of fertilization0.37% smaller and has a hatching 4% higher than the non-transgenic. Transgenic catfish feedefficiency higher than non-transgenic This shows that transgenic catfish has betterperformance compared with non-transgenic.Keywords: Transgenic catfish F-3, transgene (PhGH), transmission, Polymerase ChainReaction, growth performance
