Abstract
Cyprinus carpio commonly referred as Koi carp is
one of the most traded fish in the ornamental
aquaculture industry. The study describes the effect
of different tank colour on growth and survival of
koi carp spawn to fry by rearing them in different
coloured tank at stocking density of 3 numbers/litre
for 45 days. The initial weight and length of spawn
was 3.68 ± 0.012 mg and 7.23 ± 0.163 mm
respectively. Adlibitum feeding was done with
commercial feed (powder) and live food twice daily.
The highest mean length and weight after 45 days
of rearing were recorded in green colour tank
whereas lowest in red colour tank. The SGR was
however lowest in orange colour tank. It may be due
to the lowest stress level and better vision for feed
intake in green colour tank as compared to others.
This study concludes that the green is the best
suitable colour for tanks use for koi carp larval
rearing.
