Description:
Tilapia is the second cultured fish in the world. Up to 135 countries produces tilapia. Intensive culture systems of
tilapia such as cage culture are recently developed because of limitations of water resources. In Iran, studies
about tilapia were started in National Research Center of Saline Water Aquatics from November 2008 and some
aspects of tilapia aquaculture and culture systems are surveyed. Investigation about cage culture of Nile tilapia,
Oreochromis niloticus was performed in two culture periods of 2012 and 2014 in fresh and brackish water
conditions of Iran for the first time. Stocking densities of fish in the cages were 25, 50, 75, 100, 125 and 150
fish/m^3
. 100g fish stocked reached 272-331 g during 80 days in the first study. However, 50g fish stocked
reached 329-450 g during 145 days in the second study. Results of cage culture of tilapia in fresh and brackish
water conditions showed ranges of FCR: 1.56-3.72 and 1.08-1.87, DGR: 1.63-2.91 and 2.14-2.92 g/day, SGR:
0.63-1.12 and 1.29-1.54, production: 5.98-38 and 7.17-41.6 kg/m^3
, respectively. Stocking densities 75-125 fish/
m^3
were appropriate especially in fish reared in brackish water cages.
