Abstract :

Abstract[1] This study was conducted to determine the potential for development of aquaculture activities of Aras River with measurements of water quality parameters in the region of Ardabil province in northwestern Iran. Sampling, over a year from June 2008 to April 2009 on a monthly basis and was carried out in three research stations. The results showed that in most cases (except for total nitrogen) between parameters in different months, the difference was statistically significant (P<0.05). Although some physical and chemical factors of water from station (St) 1 to St 3 with a rising trend, but at different stations, the difference was not significant (P<0.05). Minimum and maximum physico-chemical factors including water temperature 3 to 27 °C, DO: 7.5 to 14.4 mg.l-1; pH: 7.7 to 8.6, TDS: 0.42 to 0.79 g.l-1; EC: 0.83 to 1.57 ms.cm-1; SiO2-2: 7.17 to 12.25 mg.l-1, NH4+: 0.018 to 0.174 mg.l-1; NO2-: 0.004 to 0.081 mg.l-1; NO3-: 0.492 to 2.076 mg.l-1; TN: 9.12 to 12.92 mg.l-1; PO4-3: 0.042 to 0.102 mg.l-1; TP: 0.205 to 0.536 mg.l-1and total hardness: 290 to 685 mg.l-1 calcium carbonate, respectively. Therefore, there are potentials of aquaculture development for warm water fish and cold water fish in the Ardabil province with Aras river water. But, because of limitation of water temperature should be used in initial storage of juveniles with higher weights than 100 grams. * Corresponding Authors; Email: [e-mail]
