PRELIMINARY INVESTIGATIONS IN THE INTENSIVE AND SEMI-INTENSIVE MARINE CAGE CULTURE OF FLORIDA RED TILAPIA UNDER DIFFERENT ENVIRONMENTAL CONDITIONS IN EGYPT.
National Institute of Oceanography and Fisheries, Kayet Bay, Alexandria, Egypt.
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.
