Size Structure of Areolate Grouper (Epinephelus areolatus, Forsskal, 1775 ) from the Saudi Coast of Arabian Gulf

Abstract

Areaolate grouper, Epinephelus areolatus are one of reef-associated fish species that is highly sought-after in the seafood trade. The high market demand resulted to overexploitation and population decline of the species in the wild. This paper aimed to determine the size structure of E. areolatus from the Arabian Gulf. A total of 355 samples of E. areolatus collected over the 12-month sampling period revealed high proportions of females in the sample were observed throughout the year and in size class. Males (29.3 cm, 358.44 g) are observed to be bigger and heavier than females (28.8 cm, 326.66 g). The “b” values are close to 3, which is an indication of an isometric growth. The relationship between length and weight showed significant positive correlations with p<0.0000 and r2 values ranging between 96.05 - 97.12%.
