“…This size of fish found to be similar to those documented for the species by Resen et al [14] from Iraqi waters, Arabian Gulf (13.0-43.0 cm) but was higher than those stated by Riaz et al [32] on the Karachi coast, Pakistan (16.5-35.4 cm). However, Mohamed et al [33] recorded higher lengths for A. arabicus from Iraqi waters, Arabian Gulf (14.0-40.0 cm as standard length). These differences may be related to various factors, including water temperature, food availability, population density, fishing pressure and fishing gears [34,35] .…”

In this study, the population dynamics of the Arabian yellow fin sea bream, Acanthopagrus arabicus in the Iraqi marine waters, Arabian Gulf were assessed, to contributing towards the development of management plans for its sustainable exploitation. A. arabicus is one of the species caught in large quantities as commercial by artisanal fishers. Fish samples were collected by the Shaheen steel-hulled dhow and from the artisanal fishermen from February 2020 to January 2021. The length-weight relationship was described as W = 0.030L 2.867 , indicating a negative allometric growth pattern. Of 3484 individuals ranging in total length from 13.0 to 41.0 cm were used to evaluate the growth and mortality parameters. The asymptotic length (L∞), growth rate (K) and growth performance index (Ø') were 44.6 cm, 0.34 and 2.830, respectively. The total mortality (Z) was calculated as 1.17, while the natural and fishing mortality rates were 0.75 and 0.42, respectively, and the current exploitation rate (Epresent) was 0.36. Length at first capture (L50) was 21.9 cm. The recruitment pattern occurs throughout the year, with two recruitment peaks. The yield per recruit analysis indicates that the current exploitation rate was below the economic yield target and the maximum sustainable yield, indicating that this stock underexploited. Virtual population analysis results showed that the mid-lengths (16-22 cm) experienced the highest fishing mortality. So, for management purposes, more yields could be obtained by increasing the fishing activities on this species for a substantial harvest.

“…However, the two meristic characters are inadequate to confirm the presence of two different species. Mohamed et al (2010) compared the meristic and morphometric characters of A. latus (= Acanthopagrus sp. ), their results show some relative differences of morphometric characters as the ratio of SL to height of the dorsal fin ranged from 4.75 in Shatt Al-Arab river to 6.15 in the Iraqi marine water, moreover the meristic character of dorsal fin (XI, 10) was not conspecific with the known characters of A. arabicus or A. sheim (XI, 11 or XII, 10).…”

“…Hussain et al (2001) investigated some biological aspects of juvenile and immature of it in Khor Al-Zubair lagoon. Mohamed et al (2010) studied the taxonomy of A. latus (= Acanthopagrus sp.) from Shatt Al-Arab river, Shatt Al-Basrah canal and Iraqi marine water.…”

Morphometric and meristic characteristics of two species of genus Acanthopagrus (A. arabicus and A. sheim) were described based on 19 specimens of A. arabicus and 10 specimens of A. sheim. Distinguished morphometric characteristics between two species are included; obvious black streak on anal fin in fresh specimens and the black spots on the membrane between spines of dorsal fin found in A. sheim only, while yellow lower lobe of caudal fin in A. arabicus in compared with black or dusky once in A. sheim. Pectoral, pelvic and anal fins being vivid yellow (yellow in A. sheim, anal fin with black streaks), caudal fin being yellow in the lower part, while grayish on the upper part of A. arabicus. The biometric characters of 33 out of 42 morphometric characters of A. arabicus were larger than that of A. sheim, which reported for the first time in Iraqi waters
