Abstract:
Growth rates of overwintered males of several tilapia hybrid populations from Israeli commercial and experimental farms were compared in polyculture ponds when stocked together with common silver and grass carps and freshwater prawns. Tested tilapia hybrids included Oreochromis niloticus x O. aureus Fl hybrids from two commercial stocks and one experimental stock; commercially sex-inversed F2 generation of that hybrid; and
experimental O. niloticus x O. urolepis hornorum and Taiwanese red tilapia x O. aureus hybris.
