A comparative analysis of growth performance in aquaculture of tilapia hybirids and their parent species

摘要

Growth parameters of hybrid tilapias (Cichlids) involving Oreochromis niloticus, O. mossambicus, O. Hornorum, and O. aureus as parent species were compiled from existing literature and their growth performances were compared with that of the parent species. Evidence of positive heterosis for growth in the F1 hybrids of these four species emerged. This trend was even clearer when parent species and hybrids were grown under the same culture system.
