niloticus </i>and <i>Oreochromis macrochir </i>was investigated in earthen
ponds under greenhouse conditions at Henderson Research Institute. Six
experimental ponds, three in open atmosphere and three under greenhouses were
set up. Each pond was further subdivided by hapas to make 12 experimental units
of which half were stocked with <i>Oreochromis niloticus </i>and the other <i>Oreochromis
macrochir </i>. Fish weights and lengths were recorded fortnightly and feed
intake was based on current biomass. Fish sex and breeding activities were
noted. Results showed that mean weight gain for <i>O. niloticus </i>was
significantly higher than <i>O. macrochir </i>both in greenhouse ponds and open
ponds. Feed intake was also higher leading to greater weight gains in the
greenhouse than in open ponds. Growth performance of both species improved
significantly under greenhouse culture but <i>O. niloticus </i>was much
superior compared to <i>O. macrochir </i>. Even <i>O. niloticus </i>cultured in
open ponds had superior performance to <i>O. macrochir </i>cultured in
greenhouse ponds. Turbidity, alkalinity and sulphates had positive correlation
with the weight and length of <i>O. macrochir </i>in open ponds. The study
results demonstrated that the greenhouse can enhance growth performance of <i>O.
niloticus </i>and <i>O. macrochir </i>in climatic considered less favourable
for tilapia culture. </span> </p> <p> </p>}, number={1}, publisher={Nuray ERKAN ÖZDEN}
