| Abstract | ||||
| Four groups of Florida Red tilapia WEJre reared in marine cages in order to investigate the effect of water temperature and culture systems( intensive and semi- intensive) on their survival, growth, feed utilizaiion parameters as well as production performance. Results of the study showed that 1) 20-28°C may be near the optimal water temperature in capes: and 2) intensive and semi-intensive Florida Red tilapia mariculture did not affect the fish production inversely in floating cages. Intensive mariculture group had hi$lher fish production (10.24 kg/m3) than those of semi- intensive group (6.43 kg/m-). This due to Florida 'ed tilapia fingerlings could withstand conditions with high density. low content of disnolved oxygen and excess of organrc matter. | ||||
