Abstract
Iran has the first rate of coldwater fish culture in Asia since 2005. Rainbow trout, Oncorhynchus mykiss is the main and the first fish in fisheries production of Iran. However, there is a few information about carcass composition of cultured fish in Iran. Rainbow trout samples were collected from six fish fresh and brackish water fish farms of Yazd province during February 2008. Fish muscle samples were freeze in -30°C after being homogenized, till laboratory analyses. Concentrations of metals were analyzed by atomic absorption spectrophotometer after digestion of homogenate muscle tissues with concentrated acid. Measured concentrations of minerals were as: Na822.58-1052.78ppm, K12272.75-13715.25ppm, Ca 104.75-171.03ppm, Fe 19-40ppm, Cu0.044-1.01ppb, Zn7.02-12.47ppb, CdO.879-1.099ppb and Cr 1.895-3.86ppb. Concentrations of studied minerals were not significantly different in fish muscle raised in fresh and brackish water farms. Results showed muscle of cultured O. mykiss in Yazd province of Iran were a good source of Na, K and especially Fe, with markedly low concentrations of Cd and Cr, then without any risk for human consumption. © IDOSI Publications, 2011.
