Abstract

EUTHYNNUS AFFINIS with Common name Kawakawa is an important species in scombrid fishery in the Hormozgan and southern proviences in Iran. So, study of growth and mortality parameters of this species in the region is a very crucial factor for catch management. In this research according to migration behavior of kawakawa in Hormozgan, Samples were collected from landing at four stations: Gavbandy, Kong, Salakh and Gask. During the three-year study, from 2003 to 2005, more than 25000 specimen were measured, mean±S.D Values for each year were 64/58±6/27, 64/73±7/2, and 62/96±5/31 respectively. The maximum and minimum total lengths were 25cm and 86cm respectively. Growth and mortality parameters were calculated for the 3 years as below, L¥: 89, 87 and 87 and K: 0.5, 0.52 and 0.53 and t0: -0.30,- 0.46, and -0.48, Z: 1.78, 2.72 and 2.62, M: 0.64, 0.66 and 0.67, F: 1.14, 2.06 and 1.95 respectively. Exploitation ratio (E) was estimated 0.64, 0.75 and 0.74 respectively and according to exploitation coefficient E. affinis stock is over fishing and deaceares exploitation coefficient proposed. Based on the result and in comparison with to American fisheries society (AFS) indices, Kawakawa is classified as moderate vulnerable group fishes.
