Progress
Towards Providing Fijian Farmers with a Better
Tilapia Strain: Evaluation of the GIFT Fish in
Fiji
P.B. Mather and S. Nandlal
Abstract
The
relative growth performance of the GIFT strain
Nile Tilapia (Oreochromis
niloticus) was compared
under integrated and non-integrated conditions
with the best performing ‘indigenous’ Fijian tilapia
strain, O. niloticus
‘Chitralada’ in Fiji.
Replicated trials in hapas
over two generations
(cool and warm seasons) showed that the growth
performance of the GIFT strain was significantly
better than Chitralada under both integrated and
non-integrated culture conditions. Part of the
significant difference in the mean final weights
between the two strains resulted from the relatively
‘late’ maturation of GIFT compared to Chitralada
so that somatic growth was not reduced by energy
being converted to reproduction. The data presented
here provide strong support for future fish breeding
programs to be based on GIFT strain so as to provide
Fijian farmers with a better culture strain.
