Abstract: (45 Views) |
This study was conducted for estimation growth of R. kutum from October 2023 to March 2024 in fishing grounds of Hormozgan province. A total of 286 specimens were weighed and measured. 149 samples, including 65 males and 84 females, were transferred to the University of Sari and Gonad laboratories for evaluation age and gender. Length-frequency distribution of both sexes had significant differences. The Exponential relationship between Fork length and total weight were estimated of population, males and females were as W=0.0045L2.947and W=0.0191L2.894 and W = 0.0076L3.154 respectively. Age at length data were used for evaluated parameters of K and L∞ By Goland and Holt equation. K and L∞ for population male and female were calculated of R. kutum, were calculated 0.179 year-1 and 62.84 cm, 0.23 year-1 and 52.25cm, 0.164 year-1 and 64.16 cm respectively. Tmax of R. kutum for population, male and female were estimated, 15.38, 12 and 18.29 year respectively. Phi Prime ф index of population, male and female were estimated 2.94, 2.79 and 2.82 respectively. W∞ for population, male and female were estimated, 3619, 2011 and 3807gr respectively.
