Abstract
The morphometric parameters of Pomadasys jubelini were studied using 413 specimens from June 2011 to May 2013 using different fishing gears. The length of fish ranged from 9.60 – 55.3cm (TL). Positive allometric growth (J>1) was obtained for the length - girth relationship with growth rate values J = 1.21 and 2.28 for males and females respectively. Correlation coefficients (r) for male and female were 0.91and 0.82 respectively. “r” was positive for both sexes studies. The standard – pectoral fins’ length relationship showed positive proportionate growth rate (b = 0.27) and r = 0.994. Positive proportionate growth was also obtained for total – pelvic fin’s length relationships were b = 4.49 and r = 0.947. The relationship between the girth and head length was positive where b = 4.35 and the correlation coefficient r = was 0.678.
