A study of some of the biology of the Metapenaeus affinis in the waters of the North Western Arabian Gulf

The study showed that the sex ratio of shrimp Metapenaeus affinis was highest in the summer, reaching 65% females and 35% males. This was followed by summer (58% females and 42% males), then autumn (52% females and 48% males), and the lowest was recorded in winter (51% females and 49% males). Laboring females were recorded throughout the year at various stages of maturity, with the most mature and developed occurring in the summer and spring. The largest lengths of females and males were recorded (16.7 and 12.5) cm, respectively, while the weights were (28.9 and 15.2) g, respectively.
