SUMMARY
Evaluation on performance of African hybrid catfish has been conducted to obtain a superior seeds for aquaculture in West Nusa Tenggara Province. Reciprocal matting was done using three strains of African catfish i.e. Masamo (M), Sangkuriang (S), and Paiton (P) with four replications. Natural spawning was used with injection of ovaprim hormone. The highest value of heterosis in nursery and grow up levels is observed in hybrids of S-M. The hybrid vigor of S-M in nursery level is 6.68% (survival) and 2.79% (length), while those in grow up level is 6.90% (survival), 24.03% (weight), and -3.79% (feed conversion ratio). Catfish hybrid produced from Sangkuriang-female and Masamo-male brood resulted the highest value in hybrid vigor for all of parameters in nursery and grow up levels.
