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

The African catfish (Clarias gariepinus) has been introduced several times to Indonesia, including from Thailand (Paiton strain). The breeding of Paiton strain resulted in albino individuals. The present study aimed to investigate the length-weight relationship, condition factor and biometric characteristic of those albinos. Five pairs of each albino and normal coloured Paiton African catfish were artificially bred. Larvae and juveniles from each pair were reared one month of larval rearing phase, one month of nursery phase and two months of grow-out phase, then the total length and body weight were measured for length-weight relationship and condition factor analysis, finally the biometric was characterized. The present study revealed that the relationship between total length (L) and body weight (W) of the Paiton African catfish was positive allometric (W = 0.0038L3.23 in the albino and W = 0.0027L3.27 in the normal coloured one). The albino Paiton African catfish was more rotund (condition factor of 0.79±0.07) than the normal colored one (condition factor of 0.68±0.06). Biometrically, the albino Paiton African catfish has a bigger head portion and fewer dorsal and anal fin rays than those of the normal coloured one. Despite the colour difference, the albino and normal coloured Paiton African catfish were morphologically different.
