Study on feasibility of Nile tilapia (Oreochromis niluticus) in Markazi province; Environmental capability and criteria

Unique biological characteristics of Nile tilapia (Oreochromis niluticus), including high fecundity, maturation at young ages, well-adapted to environmental conditions, and high resistance again stresses and pathogens, make it a good candidate for aquaculture. However, its potential ecological risks are the major challenges for the decision makers. This study was aimed to study on the feasibility of Nile tilapia in Markazi province. Data on meteorology, water resources, species, and protected areas were collected as well as optimum ranges for environmental parameters which Nile tilapia depend on. Results showed some meteorological parameters including air temperature, the number of frost days, and not being connected to water resources were important for site selection. Zarandieh was the best area for Nile tilapia farming due to optimum water temperature and not connected to water resources. Saveh also will be suggested if the environmental criteria are considered completely. It seems the best way to farm Nile tilapia is closed culture system. Details on the suitable commercial diet need to be investigated to develop the Nile tilapia farming in Markazi Province.
