Abstract
Four Oreochromis species were used in the
study. Progenies from the 27 cross combinations
(5 pure breds and 22 crossbreds) were evaluated
in 10 environments with different salinity levels
and agro-climatic conditions using communal rearing
concept. Among the different cross combinations
reared across environments, O. aureus x O.
spilurus gave the highest body weight and
O. mossambicus x O. spilurus, the highest
survival rate. Positive percent mean heterosis
were observed in the crosses between O. mossambicus
x O. niloticus, FAC selected line and
O. aureus x O. spilurus.
