In the Indian Ocean, salty water masses from Persian Gulf and Red Sea are important sources of salt, heat, nutrients. Across Arabian Sea, these outflows impact human biological activities, their thermohaline characteristics shapes exhibiting spatial seasonal variability. The knowledge properties is to validate realistic simulations Ocean. A classical approach study track them on specific isopyc...

Length frequency data of the longtail tuna, Thunnus tonggol collected from October 2006 to September 2007 were analyzed for evaluation of the stock parameters. T. tonggol is mainly caught by gillnet method. Yearly tuna and tuna-like catches in Iran are of the order of 174,234 mt, close to 46% of which are longtail tuna. The VBG parameters for longtail tuna were: L∞ =133.72cm K=0.35 year−1.The l...
