This paper present results of a study on stock of Kawakawa (Euthynnus affinis) in the Persian Gulf and Oman Sea (Hormuzgan marine waters) in 1378. Fork length-weight and Forklength - Girth length relationships were W=0.053E-03L2.71 and G=0.56FL+1.2 respectively.Catch analysis showed that catch value were significantly monthly and by landing places.Major landing place was Lengeh and Peak of fishing obtained in May. The Length infinity and growth coefficient were estimated 94cm and 0.53( /yera). Natural mortality, fishing mortality and total mortality were obtained M=0.66, F=1.9 and Z=2.5 6 respectively and exploitation coefficient was 0.74 in this year. Keywords: Growth parameters, Mortality rate, Exploitation coefficient, Catch, Kawakawa, PersianGulf and Oman Sea
